Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Year 2050 and beyond; the world

Under conditions like this, this will be YOUR fate in 2050 and beyond.
And warning: This will piss people off, and it will not be Shangri-La.
End of the Liberal Democratic System
You still have the democratic system we call "Liberal Democracy" these days. AKA the delusion of being able to choose better candidates for your ruler.
Unfortunately this is not the case any longer past 2050.
Leaders are EXPLICITLY stated to be lifetime rule in all nations, and are literal emperors that will rule until they die. If they take off for whatever reason, they will inherit that seat with a trusted confidant aka their closest associate.
Another trait of a liberal democracy is free speech, or your ability to question the government or the truth.
This will again no longer exist.
If you ever so deny the "[Democratic American Republic of Bananas] Holocaust of Chinese expats", "Trump is a tyrant who destroyed the United States" or "Covid is a deadly illness" fake facts, They will put you to a mental health check. If they screened you and/or it turns out that you are a "God Worshiper", "Conspiracy Theorist" or anyone who doesn't agree with Marxist Humanist ideology, you will be sent to a camp to be gassed and never come out again.
Covid Measures
You really don't think the Covid measures end after a year don't you?
It's a non-existent and neverending crisis.
Yes, Covid Policies will persist as soon as earth exists.
And these policies are bound to DRIVE PEOPLE INSANE.
Forced Masks, Social Distancing, Forced quarantines.......you named it. It's there.
Bars, pubs, theme parks, public schools, small businesses etc will go to the way of the dodo.
Save for big companies with extraorbitant prices selling foods, electronics or other necessities, nothing will exist around the streets.
If you walk out of the streets without a mask, an enforcer will ambush and kill you.
You can't even dine outside, you have to dine at home.
Curfews are forced unless under certain conditions, save for right before announcing Covid pandemics or any other emergencies, such as terror attacks, UFO fear mongering, anarchists...
Failure to comply will result in government hired fixers catching you to the camp and slitting your head with a mechanical blade.
Oh and the only business bar big companies that are still around are...
Which brings to the next point:
Legalized Killing
Gone were the days where killing is illegal.
If they can make LGBT and Pedophilia legal and a lifestyle, why not make killing one as well?
The new society is going to stress LOTS of people out, to the point that they will kill at the slightest of a whim.
If bars, pubs, theme parks, small businesses etc got driven to extinction, what do you think their employees will do?
They go out and KILL!
Piss people off by the slightest bit such as telling to them "Covid is fake," then at the next day, civilian conduct patrols will come in and kill you.
Killing, Harvesting organs, cannibalism etc...will become the DE FACTO lifestyle. And because of Covid policies, most businesses will not be able to survive the cataclysm.
And those who cannot find a job or get their job destroyed cannot conduct an uprising against big elite. If you want to conduct a popular uprising, you NEED other elites to back you.
So what do they do? They kill.
You will see more killers, bodyguards, and cannibals than there are store clerks because it's the only thing that can make you money in the true new normal.
Even civilians want nothing to do with it will go out and feast on the flesh of their close ones, not out of betrayal, but to survive.
And you better off not go out during certain times of the day because there will be so many cannibals or mafia gangs patrolling the streets waiting to catch any unsuspecting bystander.
Save for feral cannibals or angry civilians, there's also the risk of mafia and other conducted kill squads, such as the aforementioned civilian patrols, hired mercenary and hitman groups, as well as chefs (with many of them being former angry civilians).
These things had long lost their humanity, and if you get reported to them, be it tax evasion, NEET, homeless, or even muttering "Hail Trump" or the Bible and got heard, you will be caught by these paid killers and die. The chefs are the worst because they are cannibals who will basically catch anyone and everyone to get them killed, for no reason.
In certain places, infant mortality rate is expected to be 99% and the number of people who can grow to adulthood is an estimated 0.5% of the population (around the population of NYC, for example)
End of free media
Save for the aforementioned no tolerance anti thought crime laws, expect the same to happen on the internet and the TV.
Everyday, after you come back home after a hard day killing the undesireables, you turn on the TV and watch the same 3 programs on an infinity loop.
If you wanna use the computer, remember that all websites had been put under Google, Amazon or Facebook rule (assuming if these companies ever existed or similar ones replaced them), and around only 20 sites exist and all of them are big on pro-state propaganda as North Korea. Modern CCP doesn't even describe it. It will resemble North Korean internet, where not a single trace of anti-truth can exist, in general.
Video Games will all be first person shooters or political propaganda, such as WWIII or the BLM Revolution.
(Anime or Weeb culture will also cease to exist because it will be considered derogatory pedophilia or disgraces against women. Yet pedophillia is actually getting legitimized in the new world, and children can be killed as easily as adults.)
Healthcare of Death
You have to go screen yourself for health issues daily to monthly depending on the type.
Covid Screenings are daily, Mental Health Screenings are monthly, Cancer, Diabetes, cholestrol yearly scans...
Failure to pass the Covid and Mental health screenings will put you to a quarantine cell to be gassed, no exceptions.
Failure to pass the yearly ones will result in medication until death.
These scannings are all robotic and turn out false positives in a 20-30% rate.
Also, you have to be vaccinated every 6 months, these are poisonous chemicals but it doesn't matter. Also there's no such thing as a Covid vaccine because Covid doesn't exist.
Who cares if you die anyway in a society like this?
Surveillance State
Expect LOTS and LOTS of Cameras.
You might not need to know where these cameras lead to, but expect installment of surveillance cameras as a part of the law.
They will be all over the streets, your television, the ceiling of your house, the fridge, your business, whatever.
In truth, the images transmit into neighbor committees, mafia offices, hired enforcer offices, other assorted kill squads...just to facilitate these groups to arrest and kill you inside your house.
The reasons can be you homeschooling children, you lacking a job, you lacking education, you being depressed, you worshiping god, you muttering anti-truth, you not wearing masks when you go out, you gather with with more than 4 people...
But if you know less, the better.
Paying the price
Everything is taxed or expensive as hell in the new world.
The currency used is Bitcoin, and a normal killing job will only give you 6 bitcoins per month. (There are better jobs out there giving around hundreds, but it will not be for you at least)
Most necessities cost more than 18 bitcoins and food or water will cost around 0.40 bitcoins.
They will tax you 1 Bitcoin a month, possibly more.
Failure to comply to the tax will result in 2 warnings. Each warning, 2 days. At the end of 2 days, government enforcers will arrive to the spot and catch you to be gassed.
Cashless Society
Related to the point above, you no longer need cash.
Cash is obsolete, and bitcoin will take its place.
1 Bitcoin is over 10000 USD.
Also it will be done by Microchip.
But do not expect you YOURSELF to be microchipped.
You might be required to have an extra gadget in your phone or a special wristband.
Anyone without the wristband or the gadget, even at home, will be murdered fast.
The wristband or phone gadget is another one of those ways they watch over you; but they will be your only way of pay.
You will not be able to pay or get money without this phone gadget or wristband, and again enforcers will give you 1 hour of time to get 1 before you get gassed.
One of these gadgets or wristbands will cost 4 bitcoins, and phones might as well as cost 18 bitcoins for an average quality smartphone, and a high quality smartphone 30.
Report Happy Neighbours
Neighbors, associates or even your children and educated and programmed to report you for the slightest of issues.
Failure to fulfill a certain dress code of your organization.
Muttering God, Freedom, Anti-Marxism, Conspiracies, Anti Truth, or speaking it on social media or Discord.
Being an emotionally unstable mess.
No school or work. (School is always internet school while work is always necessary services, killings/bodyguards/snitchers or any combination of these.)
Not wearing a mask when you go outside.
All but one of the many reasons why you can be reported by neighbors and even your children.
If they decided to report and remove you for the following reasons, some type of authority will go in and murder you in a few hours.
Political Correctness
Like I ALWAYS said before, in the new world, beware of what you say in the public.
This includes in places like Discord or Twitter.
If you ever slip out any semblances of anti truth, holocaust denial, covid denial, religious babble etc...
Yeah, authorities knock your door and send you to be gassed, no exceptions.
Thoughtcrime doesn't result in just a chatroom ban, authorities knock on your door and send you to be gassed.
Forced Education
If you think that Covid equals no education, you are wrong.
Public schools do not exist as face to face tutoring and resemble database facilities.
However, your children have to be homeschooled by authorities every time of the day.
The subjects will be very dull, incoherent, boring and sometimes radical like some sort of anarchist or military training.
However, your child is explicitly stated not to be able of leaving their PC desk during classes, for more than 20 minutes.
Because the computers are cameras themselves, the images of your students will be transmitted to the teacher inside the "school."
Failure to comply and the authorities will take your children and you.
Same occurs if your children is homeschooled or is off from school for no reason within 6 days. This includes not having a PC to begin with; a PC costs 30 Bitcoins.
Forced Labor
You HAVE to go to work, no matter what.
Work is a part of life, and as soon as you are in the age of 15, you must find a work. Most people will have to find one and plan one from the age of 10.
This can arrange from killings, mafia, organ harvesting, bodyguards, take-out restaurants, store clerks...
You HAVE to find one.
Usually, if you are not one of the more privileged class, you have to go out and kill.
Mercy isn't an option in these cases.
No matter what the excuse is, saint or devil, you gotta kill them.
The higher the body count, the greater the talent, the higher the ranks you are.
This also means that you must stay fit at all costs. People who are not physically fit will not qualify, so are merciful people.
The more angry, brave, obedient, and warfare-efficient you are the better.
Your life is at risk, every day, but nobody cares.
Some of the people will be able to not spill blood with their own hands and find a slightly better job such as being a doctor, government official, concentration camp warden or even a teacher. But don't expect this to be you.
Altered lifespans
Because of all the GMOs, air pollution, fixer killings, mentally ill bozos, cannibals, mafia gangs....the lifespans of people will be drastically altered.
Most people will be chronically ill at the age of 50, and past the age of 45 you cannot be allotted any jobs.
The fixer and killer groups will only hire people starting from as young as 10 and as old as 30.
Infant mortality rate can arrange from 50% on lowest and 99% on highest, and chances to survive till adulthood is approximately 40% on average. In some places, this is below 0.5%.
If you happen to survive past the age of 60, you will be exterminated instantly. This is a benefit for the government because 1. You can't find anymore jobs or unable of production 2. to reduce spreading of Covid, a non-existent illness.
War on Terror
No matter what, the world 2050 and beyond will not be peaceful.
"Wars on Terror" will still occur.
Anarchist false flags groups (similar to Black Block and ISIS) built by the government, Covid pandemic waves, reptilian UFO false flags/fear mongering, Religious terrorists...ALL of these will continue to occur and in overly insane degrees to keep you scared.
Most notably, expect the Covid pandemic EVERY 4 months where the whole country will fall on lockdown for a month.
All of these aren't going anywhere but to keep you terrified and depressed.
Paid Fixers/Killers will be prohibited to deal with any of these terror groups for unknown reasons just because the Government has to solve them.
The government catches these terrorists and releases them, if there are any terrorists.
White and Black Ethnics
The world will be split into two parts. A part with polyglot populations who has every possible mixed race, and others who can maintain racial purity and are more than willing to commit genocide against anyone opposed to their race.
Most notably, Europe and the US will resemble Babylon. There will be countless ghettos, filled with all sorts of ethnicities crammed in pint size ghettos, with fights all over the place. As they call it "legs made of steel and clay." The fun thing is, Kill Groups or gangs will only hire the same race, and it makes you harder to find a job.
The other side will be consisted of fully racially brainwashed idiots who were taught pure eugenics and inferiorities. They will be indoctrinated in a way like the Nazis, Russians, Japanese and CCP educates their offspring. It usually happens in Asian or non pro-western states such as: Japan, Both Koreas, China, Russia, Malaysia... Expect these people to be ethno-supremacist and willing to kill anyone of the opposing race. (Such as Taiwanese and Japanese will happily kill Chinese, Chinese will happily kill Indians or Japanese, Russians might want to kill Americans...the inverse is true of all things.)
You can't form to rebel against the NWO or anything with these Babylonian or white law neighbors or countries.
So beware.
You HAVE to wake up right now.
This will be a rude awakening, and if this ever happens, your life will not even matter 5 cents.
The brick wall behind the curtain doesn't only have cuffs, it has spikes as well.
This is your fate in society, 2050 and beyond.
All these confrontations, cancelling, and isolation will be worth it if this is YOUR fate and you realize it.

"My transaction is stuck, what to do?" - an explainer [DRAFT]

In the last days we have been experiencing a sharp rise in price, which is historically correlated with many people transacting over the Bitcoin network. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future. Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. Although the network is working as intended (blockspace is a scarce good, subject to supply/demand dynamics, regulated purely by fees), people who are unfamiliar with it might feel worried that their transaction is “stuck” or otherwise somehow lost or “in limbo”. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.

TL;DR: Your funds are safe. Just be patient* and it'll be confirmed at some point. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins.

You can see how the mempool "ebbs and flows", and lower fee tx's get confirmed in the "ebb" times (weekends, nights): https://jochen-hoenicke.de/queue/#0,30d
* if you are in hurry there are things like RBF (Replace By Fee) and CPFC (Child Pays For Parent), which you can use to boost your transaction fees; you will need an advanced wallet like Bitcoin Core or Electrum for that though. Keep also in mind that this is not possible with any transaction (RBF requires opt in before sending, f.ex). If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1, 2.
Here’s how Andreas Antonopoulos describes it:
In bitcoin there is no "in transit". Transactions are atomic meaning they either happen all at once or don't happen at all. There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. Either the transaction happened or it didn't. The only time you can't see the funds is if your wallet is hiding them because it is tracking a pending transaction and doesn't want you to try and spend funds that are already being spent in another transaction. It doesn't mean the money is in limbo, it's just your wallet waiting to see the outcome. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.
tl;dr: your funds are safe

How is the speed of confirmations determined in bitcoin?

Open this site: https://jochen-hoenicke.de/queue/#0,2w
Here you see how many transactions are currently (and were historically) waiting to be confirmed, i.e how many transactions are currently competing with your transaction for blockspace (=confirmation).
You can see two important things: the differently coloured layers, each layer representing a different fee (higher layer = higher fees). You can point at a layer and see which fees (expressed in sat/byte) are represented in this layer. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is (miners work through the mempool always from the top, simply because the tx's on top pay them more). You can estimate that each newly mined block removes roughly 1.xMB from the top (see the third graph which shows the mempool size in MB). On average, a new block is produced every ten minutes. But keep in mind that over time more transactions come into the mempool, so there can be periods where transactions are coming faster than transactions being “processed” by miners.
The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point.
In short: what determines the speed of a confirmation is A) how high you set the fees (in sat/byte), B) how many other transactions with same or higher fees are currently competing with yours and C) how many transactions with higher paid fees will be broadcast after yours.
A) you can influence directly, B) you can observe in real time, but C) is difficult to predict. So it's always a little tricky to tell when the first confirmation happens if you set your fees low. But it's quite certain that at some point even the cheap transactions will come through.

So what happens if my transaction stays unconfirmed for days or even weeks?

Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. That’s why there is not a fixed amount of time after which a transaction is dropped from the mempool, but most nodes drop unconfirmed tx’s after two weeks [IS THIS CORRECT?]. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened. Keep in mind that in those two weeks the coins never actually leave your wallet. It’s just that your wallet doesn’t show them as “available”, but you still have options like RBF and CPFP to get your transaction confirmed with higher fees, or to “cancel” your transaction by spending the same coins onto another address with a higher fee.

Helpful tools to estimate fees for future transactions:

Here are some resources that can help you estimate fees when sending a bitcoin transaction, so you don't end up overpaying (or underpaying) unnecessarily. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here or here.
The order here is roughly from advanced to easy.
1) https://jochen-hoenicke.de/queue/#0,24h
Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past. Each coloured layer represents a different fee amount. F.ex the deep blue (lowest layer) are the 1sat/byte transactions, slightly brighter level above are the 2sat/byte transactions and so on.
The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. This should help you estimating how high you need to set the fee (in sat/byte) in order to have it confirmed "soon". But this also should help you to see that even the 1sat/byte transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool are always temporary. For that you can switch to higher timeframes in the upper right corner, f.ex here is a 30 days view: https://jochen-hoenicke.de/queue/#0,30d. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry.
2) https://mempool.space
This is also an overview of the current mempool status, although less visual than the previous one. It shows you some important stats, like the mempool size, some basic stats of the recent blocks (tx fees, size etc). Most importantly, it makes a projection of how large you need to set your fees in sat/byte if you want your transaction to be included in the next block, or within the next two/three/four blocks. You can see this projection in the left upper corner (the blocks coloured in brown).
3) https://whatthefee.io
This is a simple estimation tool. It shows you the likelihood (in %) of a particular fee size (in sat/byte) to be confirmed within a particular timeframe (measured in hours). It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that.
4) https://twitter.com/CoreFeeHelper
This is a very simple bot that tweets out fees projections every hour or so. It tells you how you need to set the fees in order to be confirmed within 1hou6hours/12hours/1day/3days/1week. Very simple to use.
Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.

Bitcoin Price Prediction 2021

Bitcoin Price Prediction 2021
What is Bitcoin (BTC)?
Bitcoin is the first decentralized digital currency. Basically, Bitcoin is a peer-to-peer payment system that is not tied to the economy of any country or to the central bank. All actions to issue new coins, process payments, and create accounts are done by equal, independent network participants. Bitcoin uses cryptographic methods to ensure the functioning and protection of the system, but at the same time, all information about transactions is documented on a virtual ledger called the Bitcoin blockchain, which is accessible for everyone to see.
Nowadays Bitcoin is the most famous cryptocurrency in the world and the number one digital currency by market capitalization.

Bitcoin achievements and future plans

The latest most impactful news from around Bitcoin were the following:
• Bitcoin halving took place on May 11, 2020.
• Bitcoin developers move forward protocol enhancements through soft forks and activating Taproot.
• Bitcoin is the most popular cryptocurrency investment for companies. MicroStrategy, a publicly-listed U.S. invested $425 million in Bitcoin. Square reportedly invested 1% of its portfolio into BTC, demonstrating strength in its long-term growth.
• According to Chainalysis 11.4M Bitcoin are held as long term investment.
• At block height 642,034 on August 3, a billion-dollar transaction took place where it only cost a small amount of 80 cents (0.0008034 BTC at 129.6 sat/vB).
• Over $300,000 in bitcoin grants being raised to support open source development and seeing bitcoin out-perform the price of gold by 100% so far this year.
There is no official roadmap of the Bitcoin project. But according to the official Twitter of the Bitcoin Core developer – John Newbery, in the near future, the Bitcoin team will focus on the Lightning Network. The Lightning teams working on c-lightning (Blockstream), Eclair (ACINQ), LND (Lightning Labs) and Rust Lightning will continue to develop the protocol.

Experts Price Predictions

Bloomberg Intelligence

Blomberg analytics says that Bitcoin’s foundation is firming for further price advances.
“Considering normal maturation, about double the time frame from $1,000 to $10,000 would come in around 2025, for Bitcoin to potentially add another zero.”

Mike Novogratz

Mike Novogratz (CEO of crypto merchant bank Galaxy Digital) hopes that BTC will reach $20,000 highs by the end of 2020.
“This is the year of Bitcoin and if it doesn’t go up now by the end of the year, I might just hang my spurs.”

John McAfee

An entrepreneur John McAfee has attracted public’s attention with his bizarre Bitcoin price predictions for the year 2020.
Twitter, by StealthEX
At the beginning of October 2020, McAfee got arrested for tax evasion charges, so the crypto community probably will not see the end of this bet.

Tone Vays

Famous derivatives trader and consultant, Tony Vays during an interview with IGTV noted his thoughts for BTC price:
“Do we think we go as high as $100,000? I’m not willing to make that statement. For me, I would be happy if the next top was around $45,000, and that can happen quickly.”

Anthony “Pomp” Pompliano

The co-founder of Morgan Creek Digital Assets, Anthony “Pomp” Pompliano is sure that Bitcoin will continue to grow.
“You know there are people who debate what the size of the gold market is but let’s just use easy numbers. Let’s say that it’s $8 trillion. That puts Bitcoin at, depending on how many are lost or stolen, $400,000 to $450,000 today. Do you think that Bitcoin is going to be the equivalent of the gold market? I don’t. It’s better. It’s going to capture more market.”

6 Reasons Why Serum Won't Succeed

6 Reasons Why Serum Won't Succeed

The world of DeFi is exploding but is it all it’s made out to be?

DeFi (decentralised finance) is most certainly the buzz in the crypto world this minute. It’s bringing similar feelings which was the 2017/18 ICO phase, where a mammoth of new projects begun to explode onto the scene, each with their own promise of new innovation and use case.
Hindsight has shown us that most of those projects have ultimately failed, or worse, were outright scams that took advantage of not so wise investors looking to make a buck. Obviously, not all projects fit that description, with many teams still around today working on and delivering their individual visions. Crypto is, after all, still a big experiment of new technology.

Enter DeFi: Serum

DeFi has exploded into the limelight over the last few months, with some tokens appreciating hundreds of percent in price. It appears to be the catalyst that has driven a huge market shift in the crypto world, and for those who’ve been around a number of years, this is a welcome change.
In this piece, I’m going to examine a particular project called Serum.
Serum is the world’s first completely decentralized derivatives exchange with trustless cross-chain trading brought to you by Project Serum.
The Serum Project is aiming to create both a decentralised exchange and a cross-chain swapping mechanism. In this article, I’m going to focus solely on the cross-chain swapping aspect of Serum.
Although the Serum whitepaper is quite short and lacking in detail, it is useful to derive some understanding of how the cross-chain swapping protocol should work. Throughout this review, I will use it to describe how the imagined protocol works.

Overview

Let's assume Alice wants to trade some BTC for ETH and Bob wants to trade some ETH for BTC using Serum. These two users are matched and agree on a price using an on-chain order book on the Solana blockchain (whitepaper provides no practical details on how to do this).
Once these users are matched, Bob must send the ETH he wants to trade to an Ethereum smart contract, plus some amount of ETH ~200 USD worth (see section 4 below) to the smart contract as collateral. Alice will also need to send some collateral to the smart contract. Once this initial setup process is complete Alice then has to send her BTC to Bob’s BTC address and if Bob receives the BTC from Alice he can then release his ETH from the smart contract sending it to Alice’s ETH address. Upon completion of this both Alice and Bob are refunded their ETH collateral.
So what happens if something goes wrong? For example, say Alice never sends BTC to Bob, after some period of time Bob can initiate a dispute. When the dispute begins both Alice and Bob present a portion of the Bitcoin blockchain information to the smart contract (see section 3). The smart contract then decides whether or not Alice did send BTC to Bob. If she hasn’t then the smart contract returns Bob's ETH and collateral to Bob and also takes Alice’s ETH collateral and gives that to Bob. The same occurs in reverse if Alice sends BTC but Bob never approves the transfer of ETH from the smart contract.
This scheme seems pretty simple, there’s no oracles and no centralised parties, however, it has a number of disadvantages.

1. User-Provided Collateral Is Bad for User Experience

Each time a user conducts a swap they must reserve some percentage or fixed amount to cover the collateral for the swap. This collateral amount needs to be present to prevent griefing attacks where users initiate swaps with no intention of ever following through and sending funds to the alternate participant.
However, this creates a poor user experience as both Alice and Bob need to have at least the value of the dispute fee committed to the contract in collateral before they conduct a swap. This is totally foreign from the normal exchange experience in which you only require a single coin and a single transaction to begin trading. For example, if using Serum to trade Bitcoin you would need to hold Bitcoin and ~200$ of Ethereum and also interact with the Ethereum chain before any swap occurs. This adds unnecessary complexity and confusion, especially for newcomers to the crypto space.

2. ETH Must Always Be on One Side of the Swap

Although the Serum method of cross-chain swapping could occur on any blockchain with smart contracts, the Serum whitepaper makes it clear the Serum arbitration contract is going to be deployed on the Ethereum blockchain. This means one party must always be locking the full value of the trade in ETH using an Ethereum smart contract.
This makes it impossible, for example, to do a single step trade between Bitcoin and Monero since the swap would need to be from Bitcoin to ETH first and then from ETH to Monero. This is comparable to other proposed cross-chain swap systems like Thorchain and Blockswap, however since those networks use AMM’s (automated market makers)and decentralized vaults to take custody of funds, the user needs not to interact with the intermediary chain at all.
Instead in Serum, the user wanting to swap Bitcoin to Monero will need to do the following steps:
  1. Send Ethereum collateral to the Serum arbitration contract
  2. Send Bitcoin to the user they are swapping with.
  3. Receive Ethereum
  4. Send Ethereum back to Serum arbitration contract
  5. Receive Monero
  6. Send Ethereum out of Serum arbitration contract
  7. Receive back Ethereum collateral
It might be possible to remove or simplify step 4, depending on how the smart contract is built, however, this means a swap from BTC to Monero would require 2 Ethereum and 1 Bitcoin transaction in the best-case scenario. Compared with the experience of other cross-chain swapping mechanisms, which only require the user to send a single transaction to swap between two assets, this is very poor user experience.

3. Proving Transactions on Arbitrary Chains to a Smart Contract Is Not Trivial

Perhaps the most central part of the Serum cross-chain swapping mechanism is left completely unexplored in the Serum whitepaper with only a brief explanation given.
“[The] Smart Contract is programmed to parse whether a proposed BTC blockchain is valid; it can then check which of Alice and Bob send the longer valid blockchain, and settle in their favor”
This is not a trivial problem, and it is unclear how this actually works from the explanation given in the Serum whitepaper. What actually needs to be presented to the smart contract to prove a Bitcoin transaction? Typically when talking about SPV the smart contract would need the block headers of all previous blocks and a merkle inclusion proof. This is far too heavy to submit in a dispute. Instead, Serum could use NIPoPoW, however, these proofs only work on chains with fixed difficulty and are still probably prohibitively too large (~100KB) to be submitted as a proof to a contract. Other solutions like Flyclient are more versatile, but proof sizes are much larger and have failed to see much real-world adoption.
Without explaining how they actually plan to do this validation of Bitcoin transactions, users are left in the dark about how secure their solution actually is.

4. High Dispute Fees Force Large Collateral on Small Trades

Although disputes should almost never happen because of the incentives and punishments designed into the Serum protocol, the way they are designed has negative impacts on the use of the network.
Although the Serum whitepaper does not say how the dispute mechanism works, they do say that it will cost about ~100 USD in GAS to dispute a swap.
Note: keep in mind that the Serum paper was published in July 2020 when the gas price was about 50 Gwei, as Ethereum use has picked up over the past month we have seen average GAS prices as high as 250 Gwei, with the average price right now about 120 Gwei.
This means that at the height of GAS prices it could have cost a user ~500 USD to dispute a swap.
This means for the network to ensure losing cross-chain swaps aren’t made each user must deploy at least $200 in collateral on each side. It may be possible to lower this to collateral if we assume the attacker is not financially motivated, however, there is a lower bound in which ransom attacks become possible on low-value trades.
Further and perhaps more damagingly, this means in a trade of any size the user needs to have at least 300 USD in ETH laying around. 100 USD in ETH for the required collateral and 200 USD if they need to challenge the transaction.
This further adds to the poor user experience when using Serum for cross-chain swapping.

5. Swaps Are Not Set and Forget

Instead of being able to send a transaction and receive funds on the blockchain you are swapping to, the process is highly interactive. In the case where I am swapping ETH for Bitcoin, the following occurs:
If the Bitcoin transaction is never received then I need to wait for a timeout to occur before I can participate in the dispute process.
And on the Bitcoin side (assuming the seller is ready), the following must take place:
If the Seller never accepts the Bitcoin I sent to him then I need to wait on line for the dispute process.
This presents a strange user experience where the seller or seller’s wallet must be left online during this whole process and be ready to sign a new transaction if they need to dispute transactions or unlock funds from a smart contract.
This is different from the typical exchange or swapping scenario in which, once your funds are sent you can be assured you will receive the amount you expected in your swap back to you, without any of your wallets needing to remain online.

6. The Serum Token Seems to Lack a Use Case

The cross-chain swapping protocol Serum describes in its whitepaper could easily be forked and launched on the Ethereum blockchain without having any need for the Serum token. It seems that the Serum token will be used in some capacity when placing orders on the Solana based blockchain, however, the order book could just as easily be placed off with traditional rate-limiting schemes.
There is some brief mention of future governance abilities for token holders, however, as a common theme in their whitepaper, details are scarce:
Serum is anticipated to include a limited governance model based on the SRM token. While most of the Serum ecosystem will be immutable, some parameters without large security risks (e.g. future fees) may be modified via a governance vote of SRM tokens.

Conclusion

Until satisfactory answers are given to these questions I would be looking at other projects who are attempting to build platforms for cross-chain swaps. As previously mentioned, Thorchain & Blockswap show some promise in design, whilst there are some others competing in this space too, such as Incognito and RenVM. However, this area is still extremely immature so plenty of testing and time is required before we can call any of these projects a success.
If you’ve got any feedback or thoughts about Serum, cross-chain swapping or DeFi in general, please don’t be shy in leaving a comment.

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

One thing that concerns me

...will Bitcoin fall from its #1 spot in the incoming bull run?
------------------------------------------------------------------------------------
Whenever I look on the charts from let's say past month for:
It's visible that whenever there is a slightest spike 3-10% in price, the fee raises from ~5 sat/b to around ~70 sat/b (14x the usual). Most of the current blocks are filled to the top with transactions. What do you think will happen when we start seeing 15% or 20% price spikes?
It is clear that Bitcoin has reached its limit in 2017 and almost nothing has been done since then. There is an argument about segwit allowing for 2MB blocks. The reality is that the 2MB blocks are very, VERY rare and it's clearly not enough to satisfy Bitcoin in the incoming bull run.
Check out this Bitcoin block size chart.
Bitcoin lightning? It is good for some crypto geeks however an average Joe will not know how to setup the lightning channel. At the current state the user experience is just so bad. I can't think about BTCLN succeeding on the global scale.
I can agree about Bitcoin being digital gold however it is not ready for the every day use. I have a strong feeling the whole cryptocurrency community will flip on its head in 2021. For the first time in history we will be seeing Bitcoin on #3 or even #4 spot.
Bitcoin has wasted potential in it.

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth

Themis (MIS) Launches Pledge Mining Platform, New Opportunity Occurs to Grow Wealth
With the development of blockchain technology, obtaining data on the chain only is no longer satisfying and how to bridge the real world and the blockchain world has always been the direction of the technological breakthrough. Under this background, Oracle Machine came to our attention. In particular, with the popularity of the DeFi concept, the industry starts to witness a boom of the application of Oracle Machine in financial derivatives, trading platforms, gambling games, and prediction markets.
At present, Oracle Machine represented by Themis is developing fast with a good momentum, leading the trend of the development of Oracle Machine and continuing to consolidate the basic technical support for the DeFi revolution. Themis’ mining system has been launched in the market, which is refreshing and appealing (see https://themisoracle.com/#/credit for details on the Themis mining).
90% of MIS, the native token of Themis, will be used for mining output. The entire mining mechanism runs through a distributed oracle protocol, which sets up three roles: data provider, data validator, and arbitration node. Reward and punishment mechanisms are applied to ensure the smooth ecological operation.
How does Themis mining work? Is it a new way to become wealthy? What are the characteristics? To answer these questions, we need to analyse the distribution mechanism, mining mechanism, and token value of Themis.
With a fairer mining mechanism, small and medium-sized miners can enjoy better benefits
One of the core values of blockchain is fairness and justice, and allowing everyone in the network to play a role in the system without permission. However, Bitcoin mining is now monopolized by several mining machine vendors such as Bitmain, leaving little space for other miners to participate. If those old PoW public chains, such as Bitcoin, has formed the head effect in mining, what about those new projects? Let's take Cosmos as an example. Since Binance joined its validator node, it has instantly ranked top with the strong financial strength and user base of the top exchange, making the small and medium nodes hard to participate.
After comparison, we can find that the mining mechanism of MIS is very friendly to ordinary users. Assuming that there are 12 mining transactions in a block, the ranking according to the MIS pledged by each transaction would be as follow:
https://preview.redd.it/1kfccgps2pg51.png?width=832&format=png&auto=webp&s=bf6c7f614c600826006bc2bf8a6026292c3b328c
The pledge ranking is based on the jump ranking weighting algorithm rather than the weighted average of the user pledge amount, which can prevent MIS from being controlled by a small number of people, avoid monopoly, creating a win-win situation in the Themis community.

https://preview.redd.it/pme9tcd62pg51.png?width=832&format=png&auto=webp&s=049f899d2a5ee3ce64007d5cc0ae3ed6167c2b3a
Compared with other mining projects, Themis has introduced a unique pledge ranking method in the mining design. Users in the best ranking area will get the most benefits, which is a good mechanism guarantee for attracting more users to participate in mining. At the same time, it can lead to the decentralization of data providers, ensuring the decentralization of the oracle system and the positive development of the community.
How can miners join in Themis mining? The answer is to become a part of the ecology by playing the role of either data provider, data validator, or arbitration node.
The data provider is mainly responsible for providing various types of data, and the data validator verifies and challenges the data offered by the data provider and provides new data. The arbitration node arbitrates the query raised by the data validator and come up with the final result.
Both the data providers and validators of Themis need to pledge MIS to obtain the qualifications, and the caller of external data also needs to pay MIS assets when accessing the data of Themis oracles. If the data has been verified as correct, data providers and validators will receive mining rewards, and the more they pledge, the more rewards they will receive.
In the mining design of Themis, miners can acquire MIS by providing verifiable random number or offering the price of in-chain assets. Whenever miners call mining contracts, the system will charge no service fee (excluding the service fee of ETH). In addition, if no mining transaction occurs within a certain period of time, the first newly-emerging block containing mining transactions will acquire all the MIS rewards. In this way, miners can be encouraged to continue mining and maintain the ecological stability of Themis.
The number of MIS mining for each mining transaction of miners is calculated as follows:
First, calculate the number of MIS mining rewards N contained in the block of the packaged mining transaction. If the height difference between the block and the previous block containing the mining transaction is y, then N = y * 20.
The MIS mining quantity of this mining transaction is M, then M=Xi/(📷)×N. Among them, X is the ranking of the MIS pledge amount in the block, and those who pledge the same amount of MIS have the same ranking.
Few official pre-mining, while 90% belongs to the community
Based on the official announcement, the distribution of MIS is:
The total amount of MIS is 1 billion, 10% is reserved for early project promotion, the remaining 90% are produced by mining, in which 75% are directly awarded to data providers, 10% to developers, and 5% as reward for arbitration nodes and ecological incentive. The production of mining will be progressively decreased and released with ETH. For some current popular VC-invested projects, institutional holdings hold more than half of blocks and unlock the block every month, which is a huge stress for ordinary pledge users. Many projects also went wrong because institutional investors do not abide by the rules. For MIS, because there is fewer official pre-mining, the selling pressure will be smaller, which is more in line with the value of the blockchain.
The release plan of developer and arbitration node and ecological incentive is as follows:

https://preview.redd.it/nld8k8gb2pg51.jpg?width=926&format=pjpg&auto=webp&s=8c2435c993cf86b2bf6b0c4d2a1935708734de97
The release plan of data provider incentive is as follows:

https://preview.redd.it/kgia5n6d2pg51.jpg?width=982&format=pjpg&auto=webp&s=ad1bfe7796fdaec58f3caede2f2a2083c0a07724
The MIS awarded per block reduces by 10% in every 4 million blocks, and the reward per block at present is 20 MIS.
We can see that the allocation of MIS follows the following principles.
First of all, as MIS is the platform certificate of Themis, it is very reasonable to reserve 10% of MIS for early project promotion.
Secondly, 90% of MIS is produced through sustainable mining. This proportion can motivate contract users and miners to conduct contract mining, truly implementing the spirit of win-win community and token economy.
Finally, among the 90% of MIS, better incentive mechanisms have been adapted, mining reward ratios are subdivided, which can attract more investors to participate in mining.
Reasonable mining mechanism highlights the project value of Themis
Themis, as a public chain that provides a mechanism to solve the problems in Oracle Machine, has a unique charm in the value of MIS.
From the perspective of the number of tokens, the total amount of MIS is 1 billion, and the total mining pool is 900 million. 90% of the tokens are generated by mining, and the mining output gradually decreases its release with the Ethereum block, showing a great potential in its future added value. The earlier you participate in mining, the more profit you can gain.
From the perspective of Themis’s ecological design, Themis is committed to the original intention of building a price oracle. The data provider pays on-chain fees and pledges a certain amount of MIS, and determines the income obtained according to the scale of the pledge; the validator can make profit from challenging the data. Also, any smart contract developer or user need to pay the corresponding fee when calling Themis, and this part of the profit will be distributed to the data provider in proportion. Through this design, a logical closed loop is completed to ensure the healthy operation of the entire ecology and achieve the goal of mutual benefit. In Themis, all parties in the ecology can work together to grow more wealth.
In all, MIS has a huge potential for future development and arbitrage, and of course, a great profit potential as well.
Today, public chains like Themis are not just a technology platform, but also a symbol of future economic operation mode which connect between the blockchain and the real world. Themis, with a fair, justice and open network through mining, is building a strong token ecology, connecting external chain data and the systems, realising data interaction between blockchain and the real world, and more importantly, creating a new mode of token economy.

The strong case for Monero – fulfilling characteristics of the future currency

I wanted to write a short article about the distinct characteristics of Monero, some of which are absolutely necessities in any future currency looking to gaining serious user adoption. Together, these separate Monero quite distinctly from the rest of the crypto field.
This is certainly nothing new to the Monero seniors here, but it might contain some new perspectives, and also give an overview to the newer cryptofolk why Monero is quite unique -

1. Transactions are private by default
The sender, receiver and amount are all hidden in Monero. This is by default, as opposed to some other private cryptocurrencies, such as Zcash, where you can optionally make private transactions. As a result, most transactions in Zcash are transparent, which makes the actual anonymity set small.
In Bitcoin there is no real anonymity, because everything occurs in a transparent blockchain – the sender, receiver and amount are all public information. This has created a market for blockchain analysis, where companies keep track of the of transactions and make profit from this information. Furthermore, because the full history of sent and received Bitcoins and other transparent cryptocurrencies can be analyzed, the newly minted coins are generally more valuable than others. This phenomenon is called ‘taint’, and it exists only in transparent blockchains.
Besides speculative holding, no real-world use will emerge in any blockchain that is transparent. No company is prepared to publicly devolve how much, when and to which suppliers they send funds. Or vice versa, no company wants its competitors to know how many customers have paid them in the last quarter. Similarly, no sensible, privacy-valuing person should be willing to share his or her personal consuming habits with the whole world, forever.

2. Community-driven – no company, no CEO
Most understand cryptocurrencies are decentralized because different stakeholders all over the world participate in the process of mining, verifying and relying information from one stakeholder to another. It is practically impossible to stop this type of well distributed global network from operating.
The network topology, however, is only one part of the decentralization. If everything is controlled by a single entity, it creates a single point of failure. As an example, if everything is funded, developed and coordinated by a single company or a few companies, which funds can be seized, executives jailed and operations stopped, how secure is this cryptocurrency in the end? In Monero, there is no company, no CEO, no office. Everything is coordinated by members of the community, globally.

3. Emission is dis-inflationary and it reduces constantly
Monero’s emission, i.e. generation of new coins, reduces every block (2 minutes). In Bitcoin, the emission is reduced every four years. This causes sudden shocks to the Bitcoin ecosystem, because miners’ rewards are halved. Such a dramatic decrease will inevitably lead to some miners abandoning their mining activities. Because proof-of-work (POW) cryptocurrencies such as Bitcoin and Monero rely on miners to secure the network, any significant decrease in mining is detrimental to the network’s security. On the other hand, the smoother emission in Monero makes mining activities more stable, which improves the security and trust of the whole system.
Another future-proofing factor in Monero is the tail emission, where the block reward will no longer decrease from 0.6 XMR after mid 2022. Minimum block reward incentives miners to continue mining even if the transaction fees do not cover all economic needs of the competing miners.
Comparing this to FIAT currencies, which are inflating 2-6 % each year, Monero’s inflation is asymptotically approaching 0 %. Even though new coins are generated by every block, the amount created per given time period remains constant after mid 2022. Contrast this to the FIAT systems, where the amount of new currency created is always increasing. Due to the compounding effect even moderate inflation in FIAT currencies causes considerable losses to all savers in medium and long term.

4. Block size is dynamic – it scales with number of transactions
Monero’s block size has no cap, which means the amount of transactions that can fit to the block is not limited. To prevent transaction spamming, preventive mechanisms have been built in the protocol.
Cryptocurrencies which implement a hard cap on the block size are susceptible to surging transactions fees. This occurs when there are simply too many transactions trying to make it into the block. Such a phenomenon occurred in Bitcoin during the peak of the last bull-run in January 2018, when the average transaction fees rose above $20.

5. Fair supply – no premine or developer tax
Supply mechanism and distribution are two elemental factors, which affect how capable the cryptocurrency is as a store of value (SOV). If a large majority of the future supply is held by a small group of people, it undermines the trust that the cryptocurrency keeps its value long term. If only a few stakeholders can massively increase the supply side of the market, the downward price risk becomes high. The more distributed the supply, the more stakeholders it takes to influence it.
Two practical implementations that undermine SOV in cryptocurrencies are premine and developer tax. In premine, the founders create a large initial amount of funds for themselves (or for their organization). Premining is an issue in some POW currencies and in all proof-of-stake (POS) cryptocurrencies, because their coin generation is not done by work. Developer tax is implemented in some POW currencies, where a portion of the block reward goes to the founders.

6. Crowdfunding and voluntarism as driving forces
Since the launch of Monero in 2014, all progression has been made by its rich and versatile community. Active members consist of several PhD researchers, developers, UX designers, translators and many other professionals of varying backgrounds. Much of the work has been made possible using crowdfunding, donors being individuals, investors and companies. Some members have participated even pro-bono, which further emphasizes the community’s trust in the project. The fact that the work is enabled by crowfunding and voluntarism is truly a strength, because it is difficult to stop ideology and people who want to be part of such force. This is in stark contrast to company-driven projects, which are much more susceptible to government oversight and control.

7. Mining is more sustainable
Monero’s mining algorithm, Random X, specifically targets general purpose CPUs and it is unsuitable to be mined with application-specific integrated circuits (ASICS). This greatly improves mining decentralization, because mining is feasible on data centers and personal computers. In Bitcoin and many other POW cryptocurrencies mining is only feasible with expensive ASICS, manufactured by just a few companies.
ASIC mined cryptocurrencies are problematic because there are very few companies specializing in mining equipment. Bitcoin’s largest ASIC manufacturer, Bitmain, has had overly much power in the ecosystem. They have stalled Bitcoin’s adoption, caused division among the community and even been one of the principal culprits for the past Bitcoin forks.
Another problem with ASIC manufacturers is their economic advantage over the rest of the mining field. ASIC manufacturers typically utilize their next generation products themselves and start selling them to the consumer market after their mining profits have reduced sufficiently due to the increasing competition. This makes normal miners second tier stakeholders in the ecosystem and it is a cause of further mining centralization.

8. Proven track record
Monero community has been working actively since its inception in 2014. Majority of the work has focused on research and development, with little efforts put to marketing. Unlike some other projects, especially those forked from Bitcoin, Monero project has an extensive technical skillset in its community and it has been one of the leading projects when it comes to both innovation and execution.
One of the Monero’s focus points is applied cryptographic research. Monero has implemented several advancements into the core protocol efficiently and with assurance. All major changes to the Monero protocol have been audited by some of the world’s leading companies specializing in cryptographic analysis, funded by the Monero community.

Addressing Common Arguments For Limiting BTC's Block Size

For a while, I've seen many BTC maximalists bring up arguments about why the block size for Bitcoin should be limited to 1 MB. I have made this post to address most of these arguments. If you disagree, feel free to make your point in the comments!

Limiting block size is what helps keep nodes cheap, and helps decentralize Bitcoin.
Let's do some math here...
With the block size of BTC being 1.00 MB, and having ~144 blocks a day, 365 days a year, there are roughly 52,560 blocks in a year. Using this data, 52.5 GB of storage will be used up in an entire year (we'll make the assumption that someone running a node buys 1 hard drive a year to store all this data).
Looking at Amazon, the average cost for 64.0 GB of storage capacity for a flash drive is roughly $10.00. This means on average, someone running a node is paying roughly 80 cents per month for storage. Okay, now let's look at the internet aspect of things. The average internet speed globally is around ~75 Mbps (which is more than enough for both BTC and BCH) and will likely run for around ~$40 a month (this is a rough figure, and slightly pessimistic, but let's take it). Therefore, doing some math:
($40.00/month + $0.80/month) x 12 months = ~$490.00/year
Okay, so it roughly costs $490.00 a year which is just a little over $1/day for running a node. Let's see how much more expensive BCH is when running the same type of node:
For BCH, everything stays the same, except for storage costs. Since the block size is 32 times bigger than BTC, doing the math, BCH will take up roughly 1.7 TB of data. For a 2 TB hard drive, the cost is roughly $60. For an entire year, that will cost about $5 per month for storage.
Taking this into consideration, we can calculate how much it will cost to run a BCH node for storage and internet:
($40.00/month + $5.00/month) x 12 months = ~$540.00/year
So in conclusion:
BTC Node BCH Node
Price (yearly) $490.00 $540.00
Price (monthly) ~$40.80 ~$45.00
As we can see, it really isn't that much more expensive, and this isn't even factoring in how much cheaper digital storage will become over time. As digital storage becomes bigger, we can also expand block size, and not have to worry about centralization.

The market has decided that BTC is better, therefore BCH is not Bitcoin.
While yes, based on hashing power, this is true, Bitcoin being Bitcoin is not about hashing power. It is about what Bitcoin was intended to do. Bitcoin was created by Satoshi as a form of peer-to-peer electronic cash system. Even in the whitepaper of Bitcoin, Bitcoin is not working the way it was intended to. From the whitepaper:

The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions.
It says it right here, one of the issues with current forms electronic payments is high transaction fees, and how they make small, everyday purchases expensive, making it bad for regular, everyday purchases.
Currently, looking at the fees, BTC costs roughly $0.50 for every transaction (fees vary every single block, but this is the current average), regardless of the transaction amount. That means if I'm making a purchase at a coffee shop for $2.00, it is going to cost me $2.50 effectively for the coffee. That means that I am paying 25% of my transaction value just to transfer my own money. What incentive would I have to make that purchase, especially when I could just use normal cash, and not pay ridiculously high fees for a normal transaction?
Let's compare this to BCH. Right now, the average fee for BCH is about $0.0025 for every transaction. When comparing that even to a $2 purchase, the fee is negligible and makes effectively no difference to the transaction amount. As we can see, BCH is far cheaper for everyday normal transactions, a.k.a. electronic cash.

Bitcoin only has high transaction fees because of the higher transaction volume, and Bitmain has spammed transactions to make BTC look bad.
As far as I know, I don't recall Bitmain spamming transactions on the network (I could be wrong on this). If someone has evidence of this, I will gladly retract this. As for transaction volume (number of transactions), we can use comparable numbers from when BCH and BTC were both having extremely high transaction volumes:
Date (DD/MM/YYYY) No. of transactions (BTC) No. of transactions (BCH) Average Transaction Fee (BTC) Average Transaction Fee (BCH)
19/08/2018 167k 129k $0.65 $0.0033
15/11/2018 241k 688k $0.74 $0.0018
19/11/2018 268k 283k $0.79 $0.0007
20/11/2018 288k 329k $1.11 $0.0006
01/09/2019 285k 575k $0.68 $0.0007
Note: The peak fees for both blockchains were $52.00 for BTC and $0.90 (which is still bad for BCH. The difference is that BCH has taken steps to ensure that kind of transaction fee would never happen again, even faced with the same amount of traffic on the network.)

The Lightning Network (an off-chain solution) is a better solution to Bitcoin's current problem than increasing the block size (an on-chain solution), and has a much higher transactions per second capability than BCH.
Yes, the Lightning Network may have a higher transaction per second capability when compared to BCH, but it comes at a cost: centralization.
The aim of Bitcoin was to make a peer-to-peer electronic cash system with a high transaction per second capability, but it also is supposed to have 3 distinct properties to it. Bitcoin should also be:
  1. Cheap (fees should be negligible, no matter how low the transaction amount)
  2. Decentralized
  3. Secure
When you take away any one of these characteristics, it becomes A LOT easier to make a currency with a higher transaction input capability, but it ignores the goal of what Bitcoin is supposed to be. For example, if you have a system of cash that is:

Cheap and secure, but not decentralized:
XRP (Ripple)
Credit Cards
Paypal
Lightning Network

Cheap and decentralized, but not secure:
LTC (Litecoin)
(DOGE) Dogecoin
Plenty of other low-use altcoins

Secure and Decentralized, but not cheap:
BTC (Bitcoin)
XMR (Monero)

BCH manages to have all 3 characteristics, all while having a transaction capability of more than 200 transactions per second. Not to mention that setting up a node on the Lightning Network is a complicated, tedious, and painful process to go through, just to put your fund somewhere where they aren't safe (you risk losing your funds pretty easily, especially if you're an everyday person who doesn't have much knowledge when it comes to technology). Not only is this the case, but eventually the funds from the Lightning Network will have to be settled on the blockchain, and when adoption increases, the fees will increase as well, meaning that you will be charged a ridiculously high amount for withdrawing your own money.
To add to this, nodes that are run by people with more resources will eventually become Lightning Hubs, meaning that they are the only few who you can go through to send a transaction to whoever you want. This makes Lightning Hubs the new intermediaries for financial transactions. Does this all sound familiar? It is literally banking right now, but with the name 'Bitcoin' slapped on top of it.

Anyway, these are all the arguments I have heard from BTC maximalists. If you have any more arguments, feel free to comment them below, and I'm willing to change my mind if you make a good point.
