Windows / Linux Guide to using Trezor with Bitcoin Core (HWI)

This is a guide to using your Trezor with Bitcoin Core. It may seem like more trouble than it's worth but many applications use Bitcoin Core as a wallet such as LND, EPS, and JoinMarket. Learning how to integrate your Trezor into a Bitcoin Core install is rather useful in many unexpected ways. I did this all through the QT interfaces, but it's simple to script. There is a much simpler guide available from the HWI github, and the smallest Linux TLDR is here
Unfortunately, I don't have access to a Coldcard or Ledger. I'm not sure how the setpin or -stdinpass parameters are handled on that HW.

( A ) Install TrezorCTL, HWI, and build GUI

You only need to set the wallet up once, but may repeat to upgrade

( A.I ) Download extract and install HWI

  1. Download and isntall Python
  2. Download https://github.com/bitcoin-core/HWI/archive/1.1.2.zip
  3. Extract it to a working folder (assumes C:\User\Reddit\src\HWI)
  4. Change Directory (cd) to working folder cd "C:\User\Reddit\src\HWI"

  12. Copy to pywin copy libusb-1.0.dll .venv\Lib\site-packages\pywin32_system32\

( A.II ) Build the QT UI files

  1. Download and install MSYS2
  2. Launch a mingw64.exe shell
  3. CD to working folder cd "C:\User\Reddit\src\HWI"
  4. Enter venv source .venv/Scripts/activate 1
  5. Run UI build bash contrib/generate-ui.sh

( B ) Create a Trezor wallet in Bitcoin Core (testnet)

You only need to set the wallet up once, no private key data is stored, only xpub data

( B.I ) Retrieve keypool from HWI-QT

  1. Launch hwi-qt.exe --testnet (assuming testnet)
  2. Click Set passphrase (if needed) to cache your passphrase then click Refresh
  3. Select you trezor from the list then click Set Pin (if needed)
  4. Ensure your Trezor in the dropdown has a fingerprint
  5. Select Change keypool options and choose P2WPKH
  6. Copy all the text from the Keypool textbox

( B.II ) Create the wallet in Bitcoin QT

  1. Launch Bitcoin Core (testnet) (non-pruned) 2
  2. Select Console from the Window menu
  3. Create a wallet createwallet "hwi" true
  4. Ensure that hwi is selected in the console wallet dropdown
  5. Verify walletname using the getwalletinfo command
  6. Import keypool importmulti '' (note ' caging)
  7. Rescan if TXNs are missing rescanblockchain 3

( C.I ) Grab Tesnet coins

  1. Select the Receive tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Select Create new receiving address and copy address
  4. Google "bitcoin testnet faucet" and visit a few sites
  5. Answer captcha and input your addressed copied from C.I.3

( D ) Spending funds with HWI

This is how you can spend funds in your Trezor using Bitcoin Core (testnet)

( D.I ) Create an unsigned PSBT

  1. Select the Send tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Verify your balance in Watch-only balance
  4. Rescan if balance is wrong (see B.II.7) 3
  5. Craft your TXN as usual, then click Create Unsigned
  6. Copy the PSBT to your clipboard when prompted

( D.II ) Sign your PSBT

  1. In HWI-QT click Sign PSBT
  2. Paste what you copied in D.I.6 in PSBT to Sign field
  3. Click Sign PSBT
  4. Copy the text for PSBT Result

( D.III ) Broadcast your TXN

  1. Select the Console window in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Finalize PSBT: finalizepsbt
  4. Copy the signed TXN hex from the hex field returned
  5. Broadcast TXN: sendrawtransaction

Final Thoughts

I did this all through the GUI interfaces for the benefit of the Windows users. Windows console is fine, but the quote escaping in windows console is nightmarish. Powershell would be good, but that throws this on a whole another level for most Windows folks.
There is also the need to use HWI-QT due to a bug in blank passphrases on the commandline. You can work around it by toggling passphrase off or on, but again, it's more than I wanted to spell out.
Footnotes:
  • 1. - Later version of python put the activate script under 'bin' instead of 'Script'
  • 2. - You can run pruned, but you need to have a fresh wallet
  • 3. - Rescan is automatic on 'importmulti' but I was pruned so it was wierd

[PSA] Electrum and Eclair both support Testnet-LN to learn about LN

Update

I rewrote this post to clean it up a bit and add more context.
With the last few drops of Electrum it's been much easier to use LN. I've played around with Electrum-desktop on testnet. Everything worked great, and it is a great way to learn about channel capacity and invoices without having to put real money at risk. Electrum has a "swap" button to adjust capacity but I think it may be broken on testnet presently. There are a few ways to adjust capacity / liquidity that I'll discuss below.

Get Electrum running

  1. Install Electrum 4.0.2 and run it on testnet enabling LN.
  2. Get testnet BTC and send it to Electrum
  3. Open a channel in Electrum with either a known entity, or use their channel suggestion
  4. Wait an hour or so for the channel to open.
  5. Perform a submarine-swap operation to give you a 50/50 capacity
  6. Wait for the swap to complete

Balance capacity

LN channels have a (local) sending capacity and a (remote) receiving capacity. To verify your local/remote capacity click on the channel and view "Details". New channels default to 100%/0% local/remote capacity, meaning you can send, but not receive. There is also some rule that requires you to be below 90% local before you can receive anything. So if you need to receive payments on LN before you spend 10% of your local capacity you will need to find a way to balance local/remote. As mentioned before, the easiest is just to spend (try starblocks), but if you don't have anything to spend on there are some other options

Test Node Visibility

Once you free up some receive capacity, you also need to ensure that your node is reachable. In the default config your node will not be publicly visible. Electrum will handle the last hop for you, but your sender still need to at least be able to route to one of the nodes you have receive capacity on. This may occationally fail causing "Path not found" errots when sending, or when others send to you. In the Electrum preferences there are some options to run local watchtowers and keep the app resident. This will help since your wallet needs to be running for it to receive payments. But even if you enable all options sometimes you will just end up on an isolated node. If this happens, take care to ensure you connect to nodes that are highly connected to others (view 1ml highly connect list).
If you want to test your visibility, just paste an invoice in this thread and hopefully someone can try to send you some tBTC-LN.

Swipe Bi-Weekly Update #6

https://preview.redd.it/n5pkxql0crh51.jpg?width=1280&format=pjpg&auto=webp&s=959d7b4051bd1c20b53cfc28ee1c4cbdd355382e
Swipe opened the month of August with the launch of its Swipe Network Staking and its announcement to run a Decentralized Finance Lending/Earn application on Binance Smart Chain. This was also followed by the plan to release product updates, events, listings, or partnerships every week until the end of 2020.
Bringing their promise and commitment true to the public, here are the activities that Swipe has released for the past two weeks:

https://preview.redd.it/5ztwd3p3crh51.jpg?width=1280&format=pjpg&auto=webp&s=a5305d9e040318cfe9e3da0a3a721c88cbaf80ae
Swipe Launches Staking/DeFi
Swipe has recently launched its test network for Swipe Network Testnet Staking and, at the same time, announced its plans to launch a Decentralized Finance Lending/Earn application on Binance Smart Chain.
With the launch of the Swipe Network testnet, users can use the Swipe Faucet to grab testnet-SXP to use on the decentralized finance application. Users will be able to bond SXP to the Swipe Network smart contract as collateral to ensure the guarantee of conversions for these exchanges. A reserve system in place to lock SXP and guarantee that the merchant and payment networks receive the exact fiat amount is in place as Swipe facilitates real-time conversions on-demand.
Users will receive up 12% APY on their staked SXP within the Swipe Network off-chain and a variable rate for on-chain. Swipe plans to enable staked SXP to earn the processing fees it charges in the future as well on top of the collateral rewards from staking.
Also, Swipe revealed its plans to launch a DeFi App on Binance Chain called SwipeFi, which will enable Binance Chain tokens to be used to earn interest on their supply of collateral to the protocol and borrow against their collateral directly on the Binance blockchain.
Swipe (SXP) Trading Competition
Last August 5 to 12, Swipe and Binance team have both committed a total of 100,000 SXP and 50,000 USDT in prizes to thank its users worldwide for their continued support and to also celebrate the Swipe acquisition and SXP/USDT listing in Futures, Margin and Spot markets. The contest was divided into three categories: a new user exclusive rewards, a trading competition, and the Lucky 99, which awarded users ranked 99th, 199th, 299th, 399th, and so forth until the 9999th place of the top 10,000 SXP traders based on their trading volume.
Swipe x WBTC
Swipe has partnered with WBTC Network and has officially been approved as a merchant for WBTC minting through the WBTC Network’s DAO Governance process. Swipe Wallet users will be able to benefit from instantly wrapping Bitcoin BTC to Wrapped Bitcoin (WBTC) and vice versa with just a few clicks. Swipe has also listed WBTC on the Swipe Wallet platform and Swipe Visa Card to enable users to buy, sell, exchange, and spend WBTC at over 60 million merchants worldwide.
SXP on CoinDCX
SXP, the native token of Swipe, is now listed and live on its second Indian Exchange CoinDCX. Trading for $SXP token is now live for CoinDCX users who wish to trade SXP/BTC and SXP/USDT.
CoinDCX trading links for SXP:

Wazirx AMA Session
Swipe Chief Executive Officer (CEO) Joselito Lizarondo, held an AMA session with the Telegram community of Wazirx, a bitcoin exchange in India, last August 7. In the AMA session, Lizarondo answered questions about Swipe, Swipe Card, its new partnership with Binance, and the recent projects that the company has announced. The community also asked if Swipe is planning to bring its card services to India as it is one of the biggest crypto market countries at present.

New Swipe Product Manual
Swipe has released a new “redefined” white paper under the title: Swipe Product Manual. The Swipe Product Manual was designed with simplicity in mind for easy and coherent descriptions of the Swipe ecosystem of products. This will describe all of Swipe’s current and future products that the team has planned. Technical descriptions and documentation will be made available, as required, per protocol, as some will have API access for developers.
The Swipe Product Manual can be viewed by clicking here or by going to https://sw.pe/ProductManual or downloading https://swipe.io/ProductManual.pdf to your desktop.
Swipe 0% Fees
Starting Monday, August 17, Swipe Wallet and Swipe Card users will no longer have to pay any fees to buy, sell, and pay with crypto. Users can now purchase, sell, and convert cryptocurrencies to and from fiat currencies without the previous 1% fee. Swipe cardholders will also enjoy waived membership fees and free card shipping.
Swipe Staking
As Swipe prepares to launch the Swipe Network Staking mainnet, the Swipe Wallet application will support SXP staking. Users will enjoy staking rewards based on their SXP balances that are held on the Swipe Wallet beginning on August 23, 00:00 UTC.
More details of the staking can be viewed at:

Swipe Reddit AMA
In his first blog post on Medium, Swipe CEO Joselito Lizarondo answered the questions that the Reddit community asked regarding Swipe’s activities and plans for the future. He talked about the new partnership programs of Swipe, its newly released “Product Manual,” and the new roadmap, which will be kept in stealth “to focus on bringing maximum value to these announcements and products.”
Read the whole transcript of Joselito Lizarondo’s AMA here:
https://medium.com/swipe/swipe-reddit-ama-8-13-80690e2f6589
Swipe and Kava Partnership
Swipe has formed a strategic partnership with Kava Labs to further grow the USDX DeFi Ecosystem as Swipe prepares to bring decentralized finance applications to the Binance Smart Chain. Swipe has also listed KAVA and USDX on the Swipe Wallet platform where users can buy and sell KAVA and USDX with a linked bank account or credit/debit card as well as enabled it to be converted and spent at over 60 million merchants worldwide with the Swipe Visa Card.
$16M+ Ecosystem Rewards Program for BNB Holders on Binance
Swipe is launching a 12-week-period $16,000,000 Ecosystem Rewards Program for BNB holders, starting August 17. This program aims to continue to promote the usage of Swipe products, including the Swipe Network Staking and Governance within a strong community. With Swipe’s partnership with Binance, a weekly distribution of 333,333.33 SXP will run to BNB holders on Binance.com.
Know more about the Rewards Program here:

Swipe’s Chainlink Based Price Oracles Now Live
Swipe has collaborated with Chainlink, the market-leading decentralized oracle network, to launch a live SXP-USD price oracle on the Ethereum mainnet. By switching to Chainlink, users receive stronger guarantees around trust and transparency in the payments process, as critical price feeds for the network are now completely decentralized and available to monitor on the blockchain.
This decentralized infrastructure ensures that reward issuances and token burns only take place based on accurate, highly available, and tamper-proof on-chain prices that have no single point of failure or absolute truth. Users can independently verify the current price, how price updates occur, which nodes are providing data to the network, and more. This means users no longer need to rely on Swipe to produce fair conversion rates.

Swipe Launches Network Staking and DeFi on Binance Smart Chain with Swipe Governance

Swipe Launches Network Staking and DeFi on Binance Smart Chain with Swipe Governance

https://preview.redd.it/ozt2j8wm9de51.jpg?width=1280&format=pjpg&auto=webp&s=77ffe561b0566f967acbac296508c6a96a9ce6e7
London, United Kingdom — Swipe is proud to announce that it has launched its test network for Swipe Network Staking and will launch a Decentralized Finance Lending/Earn application on Binance Smart Chain. Swipe, which was recently acquired by Binance, has garnered enormous growth over the past month in all avenues of its business and plans to launch a new product, feature, event, listing, or partnership every week until the end of the year.
Summary:
  • Testnet Staking Launched with testnet SXP on Ropsten
  • 12% APY for SXP Staking
  • DeFi coming to Binance Chain with BTC, ETH, BNB, SXP, BUSD, and TUSD collateral for borrowing/supplying
  • Swipe Governance Token airdrop to SXP Holders
  • Liquidity Mining on Binance Chain
  • New announcements weekly

Swipe Network

The Swipe Network (swipe.org) is the payment protocol that enables real-time crypto-to-fiat conversions for all of Swipe’s products and services (Wallet, Card, & Issuing). With the launch of the Swipe Network testnet, users can use the Swipe Faucet to grab testnet-SXP to use on the decentralized finance application.
Users will be able to bond SXP to the Swipe Network smart contract as collateral to ensure the guarantee of conversions for these exchanges. Since Swipe facilitates real-time conversions on-demand, there is a reserve system in place to lock SXP and guarantee that the merchant and payment networks receive the exact fiat amount that it processes. Most of these processes occur off-chain and are guaranteed by Swipe at the moment, but now can be bonded by the community and on-chain.
Users will receive 12% APY on their staked SXP within the Swipe Network. Swipe plans to enable staked SXP to earn the processing fees it charges in the future as well on top of the collateral rewards from staking. The main network for swipe.org will be launched in two weeks. Users can access the testnet from: https://testnet.swipe.org with a public faucet being released in the next few days. To promote the usage of Swipe Network, Swipe will be partnering with exchanges that will offer staking and enhanced initial rewards and will be announced soon.

Swipe Finance (SwipeFi) & SGV — Lending/Earning DeFi App built on Binance Smart Chain controlled by the community by the Swipe Governance Token (SGV) and Liquidity Mining.

Swipe is proud to announce its plans to launch a DeFi App on Binance Chain called SwipeFi which will enable Binance Chain tokens to be used to earn interest on their supply of collateral to the protocol and borrow against their collateral directly on the Binance blockchain. Swipe has been working with the core developers of Binance Smart Chain through the acquisition and partnerships between Swipe and Binance, to launch SwipeFi.
Users have witnessed historical highs in transaction fees, gas costs, and delays using the Ethereum blockchain for Decentralized Finance (DeFi). Bringing a complete lending/earn protocol using the battle-tested open-source protocols, such as Compound, to Binance chain gives users an immense value proposition.
Bitcoin, Ethereum, and other assets are already wrapped and issued on Binance Chain and are verifiable on their native blockchains for cross-compatibility, which will give exposure to use these assets for supplying and borrowing from SwipeFi. There are stablecoins such as BUSD, TUSD, and others that are also guaranteed on their native chains, which are wrapped and issued on Binance Chain already. Therefore, the base layer of the collateral needed to start a project of this magnitude already exists. Binance.com offers simple on and off-ramps for converting the Binance chain version to the native version (example: BTCB to BTC and vice versa) as well as SwipeFi plans to open up decentralized bridges for this wrapping.
Transactions on Binance Chain are considered one block finality, take less than ~5 seconds to complete, and cost a fraction of the price that it would cost on Ethereum. This will make DeFi transactions seamless and efficient.
SwipeFi will initially support BTC, BNB, ETH, BUSD, TUSD, and SXP to supply or borrow. The protocol will be governed by a new Binance Chain BEP2 token: Swipe Governance Token (SGV). SGV will be used on the protocol to vote on proposals and governance decisions while earned through liquidity mining so that the supplier and borrowers of the protocol can be incentivized to participate in governance as well. There will be a total supply of 10,000,000 SGV ever in existence.
On August 17, 2020, at 00:00 UTC, there will be a snapshot of SXP balances. There will be a distribution of 1 SGV per 100 SXP.
This will give an initial supply of approximately 2,999,700 SGV with the remaining SGV to be mined via Liquidity Mining by supplying and borrowing on the protocol over a 5 year period.
There will be no SGV sold or allocated to the team aside from what they already hold in SXP. This will enable users to mine over 70% of the total SGV supply over a five year period. Swipe will release the SwipeFi white paper and governance details by August 10, 2020, with plans to launch a testnet in September.

The month of July has been very busy but productive for the Swipe team. With the recent partnerships, announcements, and launches that were revealed, Swipe has indeed trying its best to achieve its mission of mainstreaming cryptocurrencies worldwide.
Swipe & Binance Seal Partnership
Swipe and Binance users got the exciting news that they have been waiting as the two companies simultaneously announced on July 7, its partnership through an acquisition move of Binance.
Binance, one of the world’s largest digital asset exchange, completed its acquisition of Swipe for an undisclosed amount. The acquisition aims to further mainstream the adoption of cryptocurrencies by bridging the gap between fiat and digital assets.
In line with this partnership, Swipe has also announced the integration of Binance Coin ($BNB) and Binance USD ($BUSD) on the Swipe Wallet application. Swipe users can now buy and sell crypto with their linked debit or credit cards, spend it to fiat via Swipe Visa Card and swap it instantly with other coins available on the app.
Also, Swipe’s native token $SXP is now listed on Binance Korea and Binance, with SXP/USDT perpetual contract with up to 50x leverage for all professional traders on the Binance platform.
Swipe Wallet v 1.5 Update
Swipe’s recent application update now lets users of choose from eight different languages such as English, Spanish, Italian, French, Portuguese, Chinese, Korean, and Japanese to use on their app. This will help users who are native speakers of these languages to transact within the app more effectively.
Download the updated app today: http://sw.pe/App
Swipe Card Rewards
Swipe Visa Card users will now have the choice to get up to 4% cashback in either Bitcoin ($BTC), Swipe Token ($SXP), or Binance Coin ($BNB) on every purchase at over 60 million merchants worldwide that accepts Visa.
European and the United Kingdom users can order their Swipe Visa cards their cards here: https://www.swipe.io/cards/
Swipe Slate Card Update
Swipe users who are interested to upgrade their current Swipe Saffron Cards to Swipe Slate cards can now do so with a lowered $SXP six-month stake requirement of 30,000 SXP!
This lowers the cost of entry for our black card by 10x from the initial 300,000 $SXP staking requirement.
Swipe x FTX
Swipe’s native token $SXP is now listed on FTX exchange. Users can now trade futures, spots, and leverage markets on FTX’s website. As $SXP markets are now live on FTX, both companies launched two events on the FTX platform to encourage users to start trading $SXP.
The first event, Buy/Deposit SXP and Split a 40,000 USD Prize Pool, was held from July 17 to 31. $20,000 prize was divided to users who net buy more than 100 SXP, and also another $20,000 to those who net deposit more than $100 or 100 SXP of accepted collateral into the FTX during the event.
The second event, which is the SXP Tokens Trading Competition, has a total prize of 15,000 USD.

TomoChain AMA with DAppBird: Public blockchain applications for businesses.

TomoChain AMA with DAppBird: Public blockchain applications for businesses.

https://preview.redd.it/a07hgl4am5t41.png?width=690&format=png&auto=webp&s=df718220bddfbeb6e3790328177769859df08874
Hi everyone. Pleased to be here! Thank you for taking your time to join me.
I’m the Chief Business Development Officer for TomoChain.
Educationally I graduated university with degrees in both Industrial Engineering and Economics from Georgia Tech, and later earned an MBA from the Wharton School of Business.
I grew up as a gaming addict and have a video game collection that is a bit unwieldy. Dozens of consoles and, at one point, over 13 classic arcade machines.
So, before crypto, I spent much of my profession in the gaming space. I was a Game Designer, Game Producer, and eventually Studio Head for a major games studio that was recently purchased by Rockstar Games. I have run my own game-related tech businesses as well.
I fell into crypto back in 2014, and over time it became a second passion of mine as I began to truly understand the value of decentralization. True ownership of data was not possible until Bitcoin came along and that is simply a powerful and game-changing message to a world structure built on an opposing foundation.
Brief Introduction

https://preview.redd.it/8p7jm15ul5t41.png?width=739&format=png&auto=webp&s=8b572bdee2c56ffa29a1d628dda7332fac0fac50
TomoChain is a Public Blockchain powered by Proof-of-Stake Voting. TomoChain launched into Mainnet 1 year ago in December 2018. It is secured by 150 Masternodes, of which I’m proud to be an operator myself. TomoChain is EVM Compatible and runs at a speedy 2000 TPS with a 2 Sec Blocktime. Gas fees are almost zero too.
Based out of Vietnam, TomoChain is Southeast Asia’s largest public blockchain. We are focusing on developing a full suite of DeFi products. We also have commercial and enterprise clients. TomoChain has a number of major crypto-partnerships including notables like Neo Blockchain, Chainlink and Crypto.com. Our Masternode network is run by some of the most recognizable players in the space as well, including Neo Global Capital, CoinGecko, HashQuark, KuCoin, and more large players are on the way.
TomoChain earned its place onto Binance.com with a fee-free listing last year by winning the BinanceDEX community vote in August 2019. Binance has written us up in a detailed Binance Research Report and awarded us the V-Label. We have also been in a number of their reports, including those related to Dapps and DeFi. We have been interviewed by Forbes.com official and had an in-person interview at NASDAQ, in the heart of Times Square, about TomoChain and our upcoming TomoX Protocol.
In China, specifically, we have been integrated into and have solid relationships with various blockchain players including HashQuark, HashKey, CoboWallet, Conflux, and many others. We launched an Ecosystem Development partnership with Neo Blockchain last December and co-hosted a meetup + workshop with them as well.

GEARED FOR REAL WORLD USE
Now, let’s talk about how TomoChain has been built for real-world use.
We’re looking at Payments & DeFi as low hanging fruit when it comes to user adoption and TomoChain is developing a suite of tools to support this. The biggest challenge for having users benefit from Blockchain on a day-to-day basis is how much friction is involved to acquire, store and use it. Even stable coins are dual currency systems. The Stablecoin and then the Native Token to pay gas fees. Blockchain is simply not user-friendly.
Our view is that the true solution for Blockchain adoption by the world is end-users shouldn’t need to know they are using blockchain technology at all. It should be a hidden technology layer, similar to payment processor settlements or even the internet distribution centers/routers that power this very AMA we’re all participating in right now. Do we need to know the underlying technology infrastructure to use them? Nope.
We are developing a system to hide this friction, so the TomoChain blockchain can be integrated into real-world applications that you use every day on mobile or web.
There are 3 protocols that we are building to enable this future: (1) TomoZ: Zero Friction (2) TomoX: The DEX Protocol (3) TomoP: The Privacy Suite.

https://preview.redd.it/irwduto4m5t41.png?width=741&format=png&auto=webp&s=56e21c8e56b86af197344d7a043d073456c53181
TomoZ: Zero Friction - Our TomoZ protocol is a core starting point to the solution for mass market use of blockchain technology. TomoZ: Zero Friction allows for token issuance and use by having gas fees paid by the token itself. That means you don’t need TOMO to send transactions. You don’t even need to know you’re using the TomoChain blockchain.
So you could buy a cup of coffee at a café using loyalty points that are TomoZ tokens. The customers redeem for their coffee or earn it, but they don’t even have to know it’s a blockchain token which they actually own.
This approach is structured to enable the next million-plus users to utilize blockchain as a technology layer. After all, the real value of any Blockchain is in its utilization of high-quality transactions.
Now, TomoZ transactions aren’t FREE. It actually does use TOMO, but that’s hidden from the end-user. The way it works is that the token issuer deposits a small amount of TOMO into a pool. Every time the token is sent, TOMO is taken from this pool to pay the Masternodes.
The key is that the end-user doesn’t need to get involved with internal workings, which is why we call it the Zero Friction protocol
Now let’s talk about TomoX: The DEX Protocol
TomoX is an upcoming DEX Protocol that allows anyone to launch their on permissionless Decentralized Exchange in minutes. It requires very little technical knowledge making it a near turn-key solution.
TomoX is the fastest DEX experience since it’s a Layer 1 protocol. This means it’s run and secured by the entire TomoChain network. Our Masternodes manage the DEX instructions directly, rather than other DEXs that operate as a Layer 2 protocol. What this means is TomoX DEXs will operate at about 50x faster than a typical 0x exchange. That significantly improves the end-user experience.
TomoX DEX operators have access to a shared liquidity pool across all DEXs. That means a user buying on one DEX can be matched with a user selling on another DEX. Of course, Operators can customize and choose which tokens to include.
TomoX is fully decentralized since the Order Book is on-chain. Many other semi-decentralized exchanges store the OB on a centralized service in order to speed up the execution. That means there is a centralized point of weakness for them. TomoX minimizes custody and security challenges that centralized exchanges have too since all users are always in possession of their assets.
TomoX is currently in testnet and you can checkout TomoChain’s own DEX, aptly called TomoDEX, here: https://dex.testnet.tomochain.com/
Here is a link to get some free Testnet TOMO that can be used on the testnet version of TomoDEX: https://faucet.testnet.tomochain.com/
And finally, there is TomoP: Privacy Suite - TomoP is currently in testnet and is going to be the FASTEST way to send tokens privately. 2-4 seconds fast!
Any token issued on TomoChain will be able to utilize TomoP to send privately and anonymously. And that’s not all. We are including access to wrapped BTC, ETH, USDT, and other tokens that can also utilize the blazing speed and privacy that TomoP will offer.
Dapp privacy is a major part of TomoP. It is going to allow for the creation of Dapps to be built to handle customer data with true privacy, including from the Dapp operators themselves. This can jumpstart a new wave of applications geared towards hiding user information, transactions, assets owned, etc.
We are issuing a new token standard (TRC21p) which will be purely private. The only data available will be on its token supply. Token issuers can optionally provide auditing access to enforcement authorities to meet regulatory compliance. What this means is if the next Global PayPal/Skrill/Alipay competitor can build their service right on TomoChain and meet the most basic criteria required to stay above board in many jurisdictions.

Questions from the host
1. It’s been stated that TomoChain was on track to be a cash flow positive business, is it currently cash flow positive? What services or products is it offering to bring in this revenue?
Yes, absolutely. Our plan is to be cash flow positive this year. This really goes back to the level of experience our executive team has. Everyone is seasoned, having come from different fields, in big business and startups. Before the crazy boom of ICOs and IEOs, raising funding for traditional startups required considerable proof that there was market fit, that there were actual customers to drive revenue, and a model for growth.
We knew that TomoChain’s funds raised during the ICO were for a space that has yet to prove itself so the company had to be smart in budgeting for an uncertain future. And part of that initial preparation was selling much of the ICO proceeds into fiat. Something MANY blockchain startups did not do, largely due to ambitious teams that are also headed by very inexperienced leaders. So while the bubble burst, we had capital to continue operations and to even scale it.
And, we ARE running a business. A sustainable business requires us to identifying areas to generate income in order to minimize risk and to sustain the business in the long term. So we do both consulting and services work by helping clients to develop wallets, launch tokens (Orbyt), build exchanges (AIS), and of course enterprise solutions on the blockchain of which we have clients based out of Japan and in the Middle East using blockchain for traceability solutions across various industries from automotive, healthcare, and food.
2. What is the most strategical step TOMO is doing to bring adoption of TOMO coin to our daily lives?
Empowering businesses with a truly scalable blockchain that can be used by thousands and millions of users. We see user adoption of blockchain coming from businesses that base their solutions on blockchain technology. And, TomoChain has a number of real income-generating companies that have built on us, from exchanges to payment services to enterprise clients. Not bad for 1 year I say, especially during a stagnant market. Here are some examples.
UcarPac – A Top 10 User Car company in Japan is building traceability solutions on the blockchain. We completed a POC at the end of last year. After the assessment, the client decided it was solid and commissioned Phase 2 to expand the development of the project for commercialization purposes
Triip Protocol – Triip is a destination service for travelers to book vacations powered by Blockchain. Triip is a Shark Tank Vietnam alumnus, and the first ICO on TomoChain. Users can book tours and staycations using Triip or TOMO tokens.
WisePass – A service that sells subscription services to get discounted Starbucks, Singha Beer, and even makeup (of all things) integrated TomoChain as a payment solution
“Undisclosed Vendor” – Soon to be announced, a large player in the corporate gift giving business is also launching a Dapp on TomoChain to allow for them to make purchases with TOMO across thousands of items.
Maka - A peer-to-peer marketplace to conveniently buy/sell TOMO and other blockchain tokens using standard payment gateways, including e-wallets and bank transfers.
Coin98 – A local Vietnam crypto media company launched an App to allow for their community to earn their TomoChain token called C98 and use it for products and services geared around investors and gamers. The reception has been HUGE. 95,000 users and generating 500K+ transactions on our blockchain within 3 months of their launch! They are proving that innovative new business models can be adopted relying on and being blockchain specific.

3. Do you have any plans to collaborate with developers or attract more Dapps built on TomoChain?
We are today. Our founders run the largest Blockchain Developer community in Vietnam and we work with a number of them to help develop solutions on the blockchain.
Our team has held Hackathons a few times over the last couple years and we have done developer workshops too, including one with Neo Blockchain. And this year we are working closely with educational institutions to launch blockchain courses in Vietnam.
Every Dapp developer we work with is a partner. We try to provide as much support as possible, both technical and marketing. A number of Dapps are games on TomoChain and we hold contests regularly to promote the developers and their titles.
Since we are focusing on alleviating the friction of blockchain technology, we are building out an API that will make it even easier for developers to integrate blockchain into standard applications. This is intended to allow standard non-blockchain application developers to operate in an environment they are accustomed to while also having the benefit of blockchain technology accessible.
Onboarding more developers will take time. However, I’m confident we’re on the cusp of something wonderful in the coming years that will change the relationship between users and applications enabled by blockchain. Entirely new economic structures can be set up since it’ll be the users owning all of their data for the first time in digital history. And true ownership is a powerful motivator that can be harnessed by innovative blockchain businesses.

⚡ Lightning FAQs ⚡

If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily,
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source

How are paths found in Lightning Network?
Bitcoin Stack Exchange Answer
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Stack Exchange Answer
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
No -- Source
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
Stack Exchange Answer
Can the Lightning Network work on any other cryptocurrency? How?
Stack Exchange Answer
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?

I'm Gavin Andresen, Chief Scientist at the Bitcoin Foundation. Ask me anything!

So what do you want to know?
I'm 47 years old and live and work in Amherst, Massachusetts with my wife, two kids and assorted pets.
I was born in Melbourne, Australia as "Gavin Bell" but moved to the US when I was five years old. I grew up in Seattle Washington, Anchorage Alaska and the Santa Ynez Valley, California.
After graduating from Princeton University (Computer Science), I worked at Silicon Graphics Computer Systems for eight years, creating 3D graphics software (Open Inventor and VRML).
My wife and I moved to Madison, Wisconsin after she got her PhD from Stanford. There I wrote a book and co-founded a startup that failed. We moved to Amherst in 1998, where I worked on an Internet Walkie-Talkie), online games for blind and sighted people, tools for Prosper lenders, a web site content management system for Gravity Switch, and part of the back-end for a search engine for computer science research literature.
Phew. That long list makes me feel old.
I first heard about Bitcoin in a May, 2010 InfoWorld article, and started working on Bitcoin-related projects soon after. I'm proud of my contributions:
You can read about what I've been working on recently at the Foundation blog.
I try not to let Bitcoin completely take over my life; I spend about eleven evenings a year as an elected member of Amherst Town Meeting. And I still have some time to ride my bicycle or unicycle, use my skeptical skills to debunk the crazy things friends post on Facebook, and read a little science fiction.
You can get an idea of topics I find interesting and how I think at my blog.
So: AMA!
Thanks everybody for all the kind words! I'm going to stop now, but I'll check in tomorrow and if there are burning questions that get eleven or more points that I haven't already answered I'll try to jump in and answer them.

Vertnode - An automated solution for installing Vertcoin node(s) on Single Board Computers

Hello Vertcoin Community,
Eager to contribute to the Vertcoin Community I began creating step by step walkthrough guides on how to get a Vertcoin node up and running on a Raspberry Pi, Raspberry Pi Zero and Intel NUC. Along with information to get a Vertcoin node up and running was also optional steps to install p2pool-vtc.
I decided that while this step by step guide might be helpful to a few, a setup script may prove to be useful to a wider range of people. I have this script to a point where I think it may be productive to share with a bigger audience, for those who are brave and have this hardware sitting around or like to tinker with projects; I invite you to test this setup script if you are interested, if you run into errors any sort of verbose console output of the error proves to be extremely helpful in troubleshooting.
The script was designed to produce a “headless” server... meaning we will not be using a GUI to configure Vertcoin or check to see how things are running. In fact, once the server is set up, you will only interact with it using command line calls over SSH. The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc.
Why run a headless node on a Single Board Computer?
The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc.
Required: USB Flash Drive 6GB - 32GB
Please note that the script was designed for Single Board Computers first and looks for an accessible USB Flash Drive to use for storing the blockchain and swap file, as constant writing to a microSD can degrade the health of the microSD.
Supports

Hardware

All of the hardware listed above is hardware that I have personally tested / am testing on myself. The plan is to continue expanding my arsenal of single board computers and continue to add support for more hardware to ensure as much compatibility as possible.
Functionality
It is worth noting that LIT can be ran with multiple configurations, the ones displayed in the Post Installation Report reflect values that run LIT with the Vertcoin Mainnet. Please be aware that the Vertcoin Testnet chain has not been mined 100% of the time in the past, if you make transactions on the Vertcoin testnet that do not go through it is likely because the chain has stopped being mined.
BE CAREFUL WITH YOUR COINS, ONLY TEST WITH WHAT YOU ARE OKAY WITH LOSING IF YOU USE THE MAINNET.

Vertcoin Testnet Coins

https://tvtc.blkidx.org/faucet/
I've included some documentation on LIT I created which includes information I found to be useful: https://github.com/e-corp-sam-sepiol/vertnode/blob/mastedocs/lit.md
Please visit the mit-dci/lit github repository for the most up to date information on lit: https://github.com/mit-dci/lit

Vertnode | Automated Vertcoin Node Installation Script

https://github.com/e-corp-sam-sepiol/vertnode

Recommended: Use Etcher to install the chosen OS to your microSD card / USB flash drive.

If you intend on installing Ubuntu Server 16.04 to your Intel NUC please use Etcher to install the .iso to your USB flash drive.
https://etcher.io/
PLEASE NOTE THIS SCRIPT MAY GIVE AN ERROR. THIS IS THE NATURE OF TESTING. PLEASE REPORT YOUR ERRORS IF YOU WANT THEM TO BE FIXED/RESOLVED. THANK YOU FOR BETTERING THE DEVELOPMENT OF THIS SCRIPT.

Ubuntu Server 16.04 Setup Details

You can use different clients to ssh into your node. One option is using PuTTY or Git Bash on Windows which is included in the desktop version of Git. If you are using Linux you can simply open a new terminal window and ssh to the IP address of your node (hardware you intend installing the Vertcoin node on).
You will need to know the IP address of your node, this can be found on your router page.
ssh 192.168.1.5 -l pi For example, this command uses ssh to login to 192.168.1.5 using the -l login name of pi. The IP address of your node will likely be different for you, in this example I am logging into a Raspberry Pi which has a default login name of pi.
A brief list of commands that can be used to check on the Vertcoin node status:
vertcoin-cli getblockchaininfo | Grab information about your blockchain
vertcoin-cli getblockcount | Grab the current count of blocks on your node
vertcoin-cli getconnectioncount | Grab the current count of connections to your node. A number of connections larger than 8 means that you have incoming connections to your node. The default settings are to make 8 outgoing connections. If you want incoming connections please port forward your Raspberry Pi in your Router settings page.
vertcoin-cli getpeerinfo | Grab the information about the peers you have connected to / are connected to
vertcoin-cli getnettotals | Grab network data, how much downloaded/upload displayed in bytes
tail -f ~/.vertcoin/debug.log | Output the latest lines in the Vertcoin debug.log to see verbose information about the Vertcoin daemon (ctrl+c to stop)
Thank you to all who have helped me and inspired me thus far, @b17z, @jamesl22, @vertcoinmarketingteam, @canen, @flakfired, @etang600, @BDF, @tucker178, @Xer0
This work is dedicated to the users of Vertcoin, thank you for making this possible.
7/20/2018 Thank you @CommodoreAmiga for the incredibly generous tip <3
You can reach me @Sam Sepiol#3396 on the Vertcoin Discord, here on reddit or @ [email protected]

Soo after almost 3 months of setting up I have my own LN full node running on RP3

Soo after almost 3 months of setting up I have my own LN full node running on RP3
I have been eager to try LN mainnet since the very beginning of it. I've found out about lnd, eclair, zap and other wallets but every scenario I tried to use it failed because of critical issues:
  • eclair does not really constitute a wallet, it's more like a credit card - you can send money but not receive it
  • lnd is okay, but requires a server and tons of resources for maintaining a full node, can't be used securely, efficiently and mobily at the same time
  • zap offers some cloud wallet (in testnet!) by default, this is a serious misunderstanding of my cryptoanarchy needs
  • web wallets - ah, forget it
So I've decided to use my Raspberry Pi with a very old laptop HDD attached (200GB so the pruning function has to be used) to create a backend wallet service and zap desktop (temporarily!) as my frontend control panel.
https://preview.redd.it/0vcq147887q11.png?width=1024&format=png&auto=webp&s=7bb6eccdd4110a857e5af0400acc2d7e1ee7ee85
Setting up Pi is easy, lots of tutorials over the internet, not gonna discuss it here. Then I had to obtain bitcoind (current rel: bitcoin-0.17.0-arm-linux-gnueabihf.tar.gz) and lnd (lnd-linux-armv7-v0.5-beta.tar.gz), create a bitcoin technical user, deploy the tools, configure and install new systemd services and go through the configs. This is a tricky part, so let's share:
# Generated by https://jlopp.github.io/bitcoin-core-config-generato # This config should be placed in following path: # ~/.bitcoin/bitcoin.conf # [core] # Set database cache size in megabytes; machines sync faster with a larger cache. Recommend setting as high as possible based upon machine's available RAM. dbcache=100 # Keep at most  unconnectable transactions in memory. maxorphantx=10 # Keep the transaction memory pool below  megabytes. maxmempool=50 # Reduce storage requirements by only storing most recent N MiB of block. This mode is incompatible with -txindex and -rescan. WARNING: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, greater than 550 = automatically prune blocks to stay under target size in MiB). prune=153600 # [network] # Maintain at most N connections to peers. maxconnections=40 # Use UPnP to map the listening port. upnp=1 # Tries to keep outbound traffic under the given target (in MiB per 24h), 0 = no limit. maxuploadtarget=5000 # [debug] # Log IP Addresses in debug output. logips=1 # [rpc] # Accept public REST requests. rest=1 # [wallet] # Do not load the wallet and disable wallet RPC calls. disablewallet=1 # [zeromq] # Enable publishing of raw block hex to 
. zmqpubrawblock=tcp://127.0.0.1:28332 # Enable publishing of raw transaction hex to
. zmqpubrawtx=tcp://127.0.0.1:28333 # [rpc] # Accept command line and JSON-RPC commands. server=1 # Username and hashed password for JSON-RPC connections. The field comes in the format: :$. RPC clients connect using rpcuser=/rpcpassword= arguments. You can generate this value with the ./share/rpcauth/rpcauth.py script in the Bitcoin Core repository. This option can be specified multiple times. rpcauth=xxx:yyy$zzz
Whooaa, this online config generator is really helpful, but I still had to manually correct a few things. The last line is obviously generated by rpcauth.py, I disabled the wallet functionality as lnd is going to take care of my funds. ZMQ is not available to the network so only my LND can use it, RPC usage I still have to think through a little, in general I would like to have my own block explorer some day but also be safe from any hacking attempts (thus I would need at least 2 RPC ports/user accounts - one for lnd, one for block explorer frontend). No ports open on firewall at this time, only UPnP is active and gently opens 8333 for block/tx transfers.
Now, synchronizing the blockchain took me time from mid-July to early September... The hard drive is really slow, also my external HDD drive has some trouble with its A/C adapter so Pi was getting undervoltage alerts all the time. Luckily, it is just downclocking when it happens and slowly but steadily synchronized the whole history. After all, I'm not paying even $5 monthly for a VPS, it is by design the cheapest hardware I could use to set up my LN wallet.
When bitcoind was ready (I've heard some stories about btcd but I don't trust this software yet, sorry), it's time to configure lnd.conf:
[Application Options] debuglevel=trace rpclisten=0.0.0.0:10009 externalip=X.X.X.X:9735 listen=0.0.0.0:9735 alias=X color=#XXXXXX [Bitcoin] bitcoin.active=1 bitcoin.mainnet=1 bitcoin.node=bitcoind [Bitcoind] bitcoind.rpchost=127.0.0.1 bitcoind.rpcuser=X bitcoind.rpcpass=X bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332 bitcoind.zmqpubrawtx=tcp://127.0.0.1:28333 
Here I've had to XXX a little more fields, as not only the bitcoind RPC credentials are stored here, but also my node's public information (it should be illegal to run nodes without specifically selected color and alias!). It is public (and I had to open port 9735 on my firewall), but not necessarily connected to my reddit account for most of the adversaries, so let's keep it this way. In fact, I also see a security vulnerability here: my whole node's stability depends on the IP being static. I could swap it for a .tk domain but who can tell if the bad guys won't actively fight DNS system in order to prevent global economic revolution? As such, I would rather see node identification in LN based on a public key only with possible *hints* of last-known-ip-address but the whole discovery should be performed by the nodes themself in a p2p manner, obviously preventing malicious actors from poisoning the network in some way. For now, I consider the IP stability a weak link and will probably have to pay extra Bitcoin TX fees when something happens to it (not much of a cost luckily!).

https://preview.redd.it/hjd1nooo77q11.png?width=741&format=png&auto=webp&s=14214fc36e3edf139faade930f4069fc31a3e883
Okay then, lnd is up and running, had to create a wallet and give it a night for getting up to speed. I don't know really what took it so long, I'm not using Windows nor 'localhost' in the config so the issues like #1027 are not the case. But there are others like #1545 still open so I'm not going to ponder much on this. I haven't really got any idea how to automatically unlock the wallet after Pi restart (could happen any time!), especially since I only tried to unlock it locally with lncli (why would I enter the password anywhere outside that host?), but let's say that my wallet will only be as stable as my cheap hardware. That's okay for the beta phase.
Finally, zap-desktop required me to copy tls.cert and admin.macaroon files to my desktop. If my understanding of macaroon (it's like an authentication cookie, that can later be revoked) is correct then it's not an issue, however it would be nice to have a "$50 daily limit" macaroon file in the future too, just to avoid any big issues when my client machine gets stolen. Thanks to this, I can ignore the silly cloud-based modes and have fully-secure environment of my home network being the only link from me to my money.
https://preview.redd.it/11bw3dgw47q11.png?width=836&format=png&auto=webp&s=b7fa7c88d14f22441cbbfc0db036cddfd7ea8424
Aaand there it is. The IP took some time to advertise, I use 1ml.com to see if my node is there. The zap interface (ZapDesktop-linux-amd64-v0.2.2-beta.deb) lacks lots of useful information so I keep learning lncli syntax to get more data about my new peers or the routes offered. The transactions indeed run fast and are ridiculously cheap. I would really love to run Eclair with the same settings but it doesn't seem to support custom lnd (why?). In fact, since all I need is really a lncli wrapper, maybe it will be easy to write my own (seen some web gui which weighs 700MB after downloading all dependencies with npm - SICK!). Zap for iOS alpha test registration is DOWN so I couldn't try it (and I'm not sure if it allows custom lnd selection), Zap for Android doesn't even exist yet... I made a few demo transactions and now I will explore all those fancy t-shirt stores as long as the prices are still in "early investor" mode - I remember times when one could get 0.001 BTC from a faucet...
https://preview.redd.it/42sdyoce57q11.png?width=836&format=png&auto=webp&s=7ec8917eaf8f3329d51ce3e30e455254027de0ee
If you find any of the facts presented by me false, I am happy to find out more in the discussion. However what I did I did mostly for fun, without paying much attention to the source code, documentation and endless issue lists on github. By no means I claim this tutorial will work for you but I do think I shared the key points and effort estimations to help others decide if they want a full-node LN client too. I'm also interested in some ideas on what to do with it next (rather unlikely that I will share my lnd admin.macaroon with anyone!) especially if it gives me free money. For example, I can open 1000 channels and start earning money from fees, although I no longer have more Bitcoins than the LN capacity yields... I will probably keep updating the software on my Pi until it leaves beta phases and only then will pour more money inside. I'm also keen on improving the general security of my rig and those comments I will answer more seriously.

Laffka opensource torshop+bitcoin

Laffka opensource torshop+bitcoin
14.8 For sane instructions, please refer to https://github.com/eruina/laffka, most relevant technical stuff is in README.md - https://github.com/eruina/laffka/blob/masteREADME.md
14.8 RELEASE 2.01
pip3 -r requirements.txt
nano app/configuration.py
nano app/templates/disclaimer.html
python3 laffka.py
https://github.com/eruina/laffka
10.8 Made one test sale, spores for for microscopy in syringe.
Can confirm, payment of mailing expenses made to my wallet rapidly and without problems.
Proof:https://www.blocktrail.com/BTC/address/1FwJdVgMZHK6WWX9t9GJnBnSVrSqfqkARB/transactions
Revamped site, welcome: http://laffka6wwduoexvb.onion/
source code will be availible 12.8
Revamped sitehttp://laffka6wwduoexvb.onion/
9.8 Items can be added, removed and edited from console panel:
Console item
And this is how it looks like listed: http://laffka6wwduoexvb.onion/item/6
Listing
Custom list of amounts to ship is in use now, howver - admin console validates only if session authorized.
What does this mean? Means that putting wrong values into database might bring whole Laffka down. Especially amount lists and orders which include both MainNet and TestNet orders.
Temporary solution would be to implement /rescue page, where admin can delete any offending row from database. Bit lame, but would do for now.
I am also puzzled at in which form package is to make. Well, have 3 days to figure it out.
8.8 At very basic level Laffka works in very basic level without any external stuff. Here:
Second part of admin console
At the risk of being labeled pedlling crap - shop example on laffka should work: http://sporeikzj77hnrxq.onion/ (yes, it is fully working little shop)
8.8 Items can be changed from console now. One can change, but not add or remove items at the moment.
Ugly as hell, but admin console in fact doesnt need to be pretty.
it needs to be functional.
https://preview.redd.it/xqpdx0rn0ue11.png?width=1195&format=png&auto=webp&s=c495e2c89b59c7a0fcc35a2c123a83a8667c35d1
6.8 Orders part of console is finished. Orders shown - ones that are paid, and ones that are marked with note.
Rather nifty, but probably requires additional changes after code is released.
Orders page
Order 98 will be shown even if Wif key is swept. Order 99 will disappear after Wif key is swept. Simple, and probably will require additions, but would do for now.
Time to fiddle with items.
5.8 Something like this. Subject to change!
Console, early version
5.8 Admin console is a bit of a puzzle. At the moment, I think of showing orders that has been paid AND orders which has note left by admin. Should be sufficient for first release version.
I also deem it bit pointless at the moment to validate values of admin console forms, orders and items.
4.8 pip3 module requirements now include flask-login and flask-session.
It would be interesting to run few instances of Laffka with common order table. This way one can make and keep a lot of small darknetshops in hidden onion land, with overall price well under 50€.
Login and session are required for shopowner identification, means it is in progress, after which packaging only left.
It might be interesting to make liveusb with sole purpose of running small Laffka-torshop.
Word Laffka is from finnish Lavka, which means small shop, usually at market place.
2.8 I should mention, that purchase process is very nonintrusive for customer. Gives a bit strain to shop owner, but not much.
1.8 Meanwhile I suffer from heat and overuse of bandwith, here is small presentation, how payments work.
Suppose customer would like 3pcs of Test item 1:
Generic order of Test item 1
So, customer clicks 3pcs, and arrives at second page:
Address part of ordering
Finally customer arrives at personalized payment page
Check out
After which customer is asked to pay for order:
Electrum Testnet
After order being paid, payment reflects on orderpage(http://laffka6wwduoexvb.onion/pay/mryJ3ukrFHoUmdHeSkR4XZcwe3wvG3pRkd)
After payment been through:
Finished payment
Shop owner can claim funds by sweeping own private key from admin console(not finished yet)
Private key cUP4jznEGX8EDMPw813w4B7E6fBo3FDXPqhRLp5sFHq3v3KCgP2z
All right, now lets swipe:
Sweep-sweep.
Voila, New transaction received
Received payment
So, all in all customer paid 4.64526, and shop owner received 4.64108, difference is paid for bitcoin transaction, while private key was swept.
Nifty.
1.8 FFS. Seems I've depleted bandwith for august.
need to tune tor more careful.
UPDATE: temporarily example can be accessed at http://laffka6wwduoexvb.onion/. test22cq47 doesn't work for now.
1.8 Satellite skeleton is done, orders page in progress.
Makes sence to finish satellite with instructions after admin console is done.
Still fucking hot in here, coding advances very slow, yet I believe it is going to be finished before deadline, 12.8
31.7 Satellite is in works, meanwhile testshop can be found at http://test222cq47k6qrn.onion/
http://laffka6wwduoexvb.onion/ is going to point to project site itself, with sources and instructions.
31.7 My bad.Had theoretic items in a shop, and was considered peddling crap by administration.
Exchanged those to Test item 1 and 2, as seen here: http://laffka6wwduoexvb.onion/
Project is now hosted separatedly from development, and should be availible all the time.
Of course, since it is early Alpha, it can fall, but otherwise you are welcome to make test order and pay it with testBitcoins.
It is fucking hot here, literally cannot concentrate myself to do anything useful.There is but two things left before release:
  1. Admin console (for fiddling with items, and sending orders)Have idea how to elegantly handle orders, but not items
  2. Some form of ready to deploy package
Also, I must mention requirements. Installing whole thing on pristine CentOS 7.4 was under 15mins, so here are first requirements:Python3 and python3-pip
And pip requirements for now: flask, requests, Flask-APScheduler, Flask-WTF, bitmerchant
12.8 is still deadline for release.
29.7 Nifty!!!
Too hot to think about admin console, yet it is not harder to run few instances of Laffka on machine than typing:flask run --port=5678andflask run --port=6789
in two different consoles. Actually nifty. No conflicts, two absolutely separate instances having nothing to do with each other.One can already generate sales, yet database from admin perspective is accessible only from some DB Browser.
29.7 I have observed, that visitors are coming to payment page, where it asks address and then most probably close page.
Don't be afraid, type some stupid shit there, it will transfer you to payment page itself. Don't be afraid to pay order neither, since testBitcoins do not cost anything. Neither I receive any information, except routes of visitors.
Answering questions: Design is no priority whatsoever. Since Laffka is developed with Tor in mind, there is no graphical elements at all. May be later CSS will be tweaked and ability to add pictures to items, but I don't see myself developing cushy designs for Laffka.
It should be lightweight, fast and simple. Functionality is of priority here.
Then there is question "How can I participate". At the moment only by testing is a method or participation, ie making order and paying with testBitcoins. After first release, one can branch code and develop own branch. I am not yet ready to release first public version.
Before releasing, there is necessity to create make/setuptools.py
28.7 Hello.
Always wanted my own small shop on darknet, not consolidated markets, which are riddled with such problems as exit scams, DDOS attacks, rules which you couldn't change and whatnot.
Never found anything suitable, heard about torshop, but apparently it was a scam.
Which is quite understandable - never trust your private keys to unknown third party, it is just plain stupid.
I think I came up with solution. Well, I didn't invent idea of opensource, but I think I know how to make this thing work.
Let me present Laffka, in its very much alpha stage.
It is written in Flask+python3, and uses* sqli*te as database engine. Doesn't require blockchain downloading, checks transactions online and generates private keys for bitcoin wallet sweeping, thus getting payments for *a t*x price.
Should work clearnet too, I don't see why not. Works excellent and made specially for hidden service purpose.
No binaries whatsoever, everything is in clean and understandable python+html. No surprises, no hidden stuff. Plain opensource. And plain opensource will be released, without tricks.
There are some pypi dependencies, I will list them in documentation upon release.
And release is coming soon. Not yet, but I've decided to draw a little attention, since Laffka accepts and processes payments, albeit on very basic level (no admin console at the moment, lot of functionality still missing)
Please observe alpha version 0.02 in action - http://laffka6wwduoexvb.onion/
make order, or observe existing order - http://laffka6wwduoexvb.onion/pay/mxprSXCVX7WvvADDDVCrKmEhfsvWvznawu
(observe increasing wallet balance upon sending testBitcoins. No blockchain involved.)
It would be greatly appreciated if you'd make order and pay for it. TestNet, not MainNet, so no money involved whatsoever. I require some feedback about project. You can run Electrum in testnet electrum --testnet, and get testBitcoins at some faucet, https://testnet.coinfaucet.eu/en/ for example (there are others)
If link doesn't work, it is ok - means I've took it off, and it will be coming back online bit later. Resource will run continuously when I finish satellite for Laffka (ToDo list is on index at http://laffka6wwduoexvb.onion/)
Thanks for attention.

Help us create the best mobile wallet – join Billion test-net beta! [iOS]

Hey there, folks!
We are a team of cryptocurrency enthusiasts behind Billion Wallet (screenshot) for iOS. It's common among developers to think about their project in a special way, and we are not an exception – we do feel like we created something different. We believe we have a reason to think like that, and we invite you to participate in a public beta test that allows you to play with all features without spending real bitcoins ㋛.
We value Bitcoin Cash very much, but due to roadmap inertia we still do not have a version that works natively with Bitcoin Cash – we are sorry for that. What makes us very sad, is that our posts on Bitcoin are always deleted for no apparent reason and without any explanation. It's not a kind of treatment we expect – we work hard for the benefit of the Bitcoin infrastructure, we are a very small, self-funded team of cryptocurrency enthusiasts and the ability to participate in open communities is vital to us. We hope you do not mind we invite you to test the wallet that works in a test-net Bitcoin Core chain.
Here is what's unique about Billion:

Private

Not only Billion never asks you to enter email or phone number, but it also implements a unique feature called Reusable Payment Codes. Payment Code is a special kind of address that can be freely published online and no one will be able to calculate the amount received. Kind of Monero Stealth Addresses but in a Bitcoin world! You can read a high-level overview of this technology on our Medium blog (a 10-min read). Billion is an SPV wallet that does not depend on a central server for any critical functionality.

User-Friendly

To make cryptocurrencies easy to use for everyone we have developed an entirely new visual paradigm. If you ever experienced struggle while using a crypto wallet, we encourage you to try Billion – that's something new on the market. You can read a brief explanation of Billion user-interface on Medium (4-min read), or watch a 30 seconds-long promo video. Please forgive us the part of the video with 10$ fees :)

Social

One of the most important aspects of Billion is a system of contacts based on Payment Codes. Once you have added your friend to a list – either using Air Connectivity (Bluetooth connection) or by importing/scanning a Billion Card – you can make payments without any copying/pasting/scanning. This way, a payment workflow is simplified drastically, and the privacy is not sacrificed at all. Moreover, such a system is cross-platform: you can add contacts from other wallets that support Payment Codes. As of now, Samurai (BTC-only) and Stash (BTC + BCH)) on Android are two wallets that support Payment Codes (and Stash can be used on TestNet). And by the way, Stash Wallet works great in test-net so you can experience the magic of cross-platform Bitcoin contacts right away!

How to Participate

  1. Download Billion TESTNET Edition from the App Store
  2. Create a new wallet. Once it's synced, tap onto the balance tab to display your Billion card. Assign a pseudonym and avatar to make it more recognizable.
  3. Share your BillionCard picture in comments, or join a dedicated Telegram channel. We will send you some test-bitcoins so you won't need to use any faucets!
  4. Add BillionCards of other users who participate in beta testing to your list of contacts (tap onto 'Contacts' icon -> 'Add contact' -> 'Scan BillionCard' -> 'Extract QR-code from picture' and choose the image you saved to media library). Send them some coins, and tell us how do you enjoy the workflow.
  5. If you have friends with whom you can test Billion irl, we urge you to test Air Connectivity and Billion Requests.
Thanks for reading and let's create the best mobile cryptocurrency wallet together!

P.S.

We have to polish the version on a single platform with one cryptocurrency first, and we need your help. We are looking forward to testing Billion with you!

  2. The UOS testnet was launched. BP nodes, RPC nodes of the UOS testnet were deployed. Currently, the UOS testnet runs normally.
  3. TPS testing of the UOS testnet were taken. The performance of the UOS sidechain testnet is equal to that of the EOS mainnet.
  4. Usmart, the UOS wallet browser plug-in was developed and has been in the application of the listing on Chrome App Store. USmart can provide convenient payment functions for Dapps on UOS, and will support USC and UT in the future.
  5. The bind between Usmart and UDFS registration was in the pre-research for users’ convenient operation;
  6. Smart contracts for UDFS score have been in development;
  7. UMaster, the masternode management system, was test and the system management preparation has been gradually advanced.
Peripherals
  1. The beta test of Ulord V 2.0.0 was completed and some functions were added: escrow account function, discovery plaza, and honeycomb game; the exchange function between UT and SUT was added.
  2. Ulord V2.0.1 entered the development, including completing the escrow account replenishment, cash withdrawal function, and completing the UT red envelope function.
  3. The developer community V 1.2.0 is officially launched (https://ulorder.one/)

The backstage new function: data statistics, forum management, financial management, proposal management and task management module.
  1. The block browser of the UOS testnet has been online: http://testnet.uos.ulord.one/.

Test
Developer Community V 2.0.0 function test:
  1. Task invitation was added. If user A invites user B successfully, both can get UT as bonus.
  2. Forum function was added. You can post, comment, like, click topic list and view the details.
  3. The personal center and the forum message were optimized. Users can view their post and reply records.
  4. The sidechian UOS function was added:
a. User can create a sidechain UOS account in the testnet bar and get UOS coins through the UOS faucet. Users can view related data through the UOS block browser.
b. In the resource bar, users can download USmart tools and the sidechain UOS tutorials.
  1. The masternode proposal function was optimized:
a. When the non-masternode user views the proposal details, only part of the information content was displayed and he has no voting right; When the masternode user views the proposal details, all the proposal details were displayed and he has the voting right;
b. If the proposal is rejected, the users can reapply;
c. The proposal voting failure interface displays related information.
This version was tested and launched on December 28, 2018

Operation Progress

  1. On December 26 and 29, Ulord announced twice the list of excellent Ulord users in the Ulord beta test and gave them awards. Sincere thanks to these initial users of Ulord.
  2. On December 29, the Ulord sidechain UOS testnet was officially launched. UOS has innovation in voting mechanism, incentive mechanism, throughput, irreversible block mechanism, and joint alliance. The tutorial was released (https://mp.weixin.qq.com/s/OiUdn0qhZSBLQNmJTDOkKQ).
Welcome developers to install the UOS testnet.
  1. On December 30 and January 1, Ulord New York office and the strategic partner HOMEBLOC jointly launched the “10th Anniversary of Bitcoin Genesis Block”. Blockchain pioneers, KOLs and technology enthusiasts gathered to say goodbye to 2018 and welcome the new year of 2019.

Terminology

UOS (Ulord operation system): UOS is the Ulord operation system. It is the second sidechain based on Ulord. It uses the DPos consensus protocol to extend millions TPS. UOS has strong compatibility. The EOS contract applications, with slight configuration, can run on UOS; UOS consensus prevents BP nodes from voting to each other; UOS joins BP penalty mechanism to prevent BP from doing evil; UOS irreversible block mechanism makes block confirmation faster. UOS fundamentally reduces the technical threshold and helps blockchain projects to land quickly.
