/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin

The First-generation Terminal — MoonBot

The First-generation Terminal — MoonBot

Moonbot
Our team has developed and is supporting the trading terminal MoonBot which was introduced in October 3, 2017. Currently, the performance of MoonBot surpasses that of most existing trading systems as a result of its advanced functionality and the high security features designed to protect your trading activities.
Secure Connection to the Exchange
The connection from MoonBot to an Exchange is carried out using special keys that the user receives from an exchange such as Binance or Bittrex.
MoonBot connects securely to cryptocurrency trading Exchanges through two special keys which are uniquely and only known to their owner. These are the API key, and the Secret key, both of which the users receives directly from the Exchange.
The MoonBot terminal then receives data and information from the exchange’s API collected at several different access levels, including:
Public information (publicly accessible data related to trading in general):
  • charts;
  • quotes;
  • orderbook;
  • real-time executed orders.
  • Authenticated information (unique to the users and which requires authentication access using the special keys): personal account status (wallet balances);
  • user transactions (such as the details of executed trades).
After receiving the various data information from the exchange, the terminal records these data in a local database for further processing and application.
Security Systems
The MoonBot terminal provides completely private storage of all your personal data!
The MoonBot team has absolutely no access to personal data, you are the only one controlling its security and have complete control over access to your details.
The MoonBot team are not able to withdraw, nor to move, any funds from your personal Exchange account or wallet.
You can therefore safely use the terminal for trading, receiving public information from the Exchange, and should you wish to share with others, the trading data on your account.
You therefore are the only person with control and access to your Exchange wallet, and can be completely assured of the absolute security of your private funds.
Lightning-fast Execution of the Orders on the Exchange and Order Status Update
Depending on the distance of the user from the exchange servers, the delay in order execution should not exceed 1 second. Theoretically, the delay can be reduced to a minimum intangible — 10–20 ms. Below is presented a very short extract(4 seconds in total) of the MoonBot log text file with brief explanations and highlights of the key features.

The MoonBot log text file with brief explanations and highlights of the key features.

Tick Chart. Display of All Orders on the Chart
Thanks to the API connection to the exchange, the terminal receives stream data of all filled orders on the exchange as soon as they were processed by the exchange servers and immediately displays them on the chart.
Tick Chart.
Thus, the visualization of the current state of the market is provided in real time with an accuracy of tens of milliseconds and as detailed as displaying each order on the chart.

Auto Trading on Signals
Fully automatic processing and trading off Telegram signals as well as parced TradingView alerts.

Automatic Detection of Market Conditions and Reaction to its Changes
Thanks to streaming data acquisition, the terminal monitors all available markets simultaneously, and is therefore able to react almost instantaneously as favorable trading possibilities are presented. And due to the minimal delay in the execution of orders, MoonBot responds to abnormal changes almost instantly.

Advanced Orders. Stop Loss, Take Profit, Trailing Stop
OCO orders (one cancels the other) are one of the most sought-after functions from both the Exchanges providing liquidity to the markets, and applications running on top of the exchanges. The modern Trader cannot trade without the basic “smart” functions and addons to traditional exchange orders and considers them to be the minimum necessary set in their armory.

https://preview.redd.it/3gsh12b42m931.png?width=1200&format=png&auto=webp&s=7f21bd7e7505f9bb5a95555cf355bb6f1f5efab4
Stop Loss
One of the most important tools for Traders is to be able to place orders whilst practicing safe money management in order to mitigate against losses. One of the most important safety tools is to use a Stop Loss, which is especially important in volatile, low liquidity markets.
With MoonBot, the user can set a Stop Loss threshold (either as a percentage of the order price, or as a number of price points), which their strategy can accept should the price move in the opposite direction to that expected. When this threshold value has been reached, the order will be closed automatically.
Technically, a Stop Loss can be set up in two ways: either as a stop-limit order placed directly on the exchange at the same time as the initial position is opened; or as a function controlled in real-time by the MoonBot terminal itself. Additional types of conditional Stop Loss functions include:
  1. Additional and conditional Stop Losses – these are activated by a timer, and depend on the price reached. Thus Moonbot can raise the Stop Loss to a break-even point, or can be set to move upward to follow coin growth and to achieve higher profitability.
  2. BV/SV Ratio Stop Loss — this is a measure of buying/selling pressure and depends on the ratio of the volume of coin purchases compared against sales over a given time range. For example, if the number of sales exceeds the number of purchases, then this Stop Loss would be activated
  3. V-STOP — this is a stop which depends on the volume in the orderbook, where a price and volume level is set, which if broken will activate the Stop Loss.
  4. Trailing Stop — Trailing Stop is a General Stop Loss Management Tool. This very important feature allows the Trader to maximize profit in an automatic mode by following upward price movements, until the price reverses by a preset amount. At that stage the Stop Loss is activated.
    Take Profit
The Trader can fix the profit gained as the value of an asset increases in several ways:
  • By closing the position after a predefined profit percentage has been reached.
  • By remaining in the position, and setting the Stop Loss level to break-even, or to higher profit levels.

Algorithmic Trading
At the moment, MoonBot has 13 types of strategies in-built (manual) using specific and well-proven algorithms (algorithmic trading or algo-trading).
Together these have more than 200 adjustable parameters that can be adjusted to optimize their profitability across the wide range of trending and ranging markets that occur.

Trusted Management
MoonBot includes a successful and well-tested Trusted Management feature, in other words — Copy Trading:
  • All trade actions from the Master Terminal are repeated on the Follower’s Terminal (slave terminal).
  • The Follower’s deposit remains securely in their own personal exchange account.
  • The Trusted Management feature does not have direct access to money, or to direct trading on someone else’s account, but manages only its own Exchange orders, simultaneously broadcasting encrypted messages to Followers terminals containing all Master actions.

Trust Management is successfully implemented and used by members of our community. The statistics of those TM Traders who share their results can be reviewed on the website — stat.moon-bot.com on the RatingTM tab.
Community
During the two years of development of the MoonBot terminal, more than 30,000 copies have been registered and used by our Community of Traders.
Every day several thousand people trade cryptocurrencies using the MoonBot terminal, making daily approximately one hundred thousand manual and automatic transactions only on the leading crypto-currency exchange — Binance.
The existing community of traders is actively developing. The MoonBot project has its own active pages on popular social networks, in dedicated Telegram channels divided by topics, and also its own Trader’s forum available to subscribers.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Ecommerce and Accounting System Integration with BTC

Hello
I own a company that builds custom applications on top of a fairly popular financial system. The system has quite a few users and not only has accounting functionality, but also is used to host webstores/ecomm sites. It's a purely hosted app. No servers here that anyone has access to. Some very big customers use this system
I have been watching BTC for some time, and never pull the trigger on getting invested, but with the European craziness figure now is the time to support this.
If we want to have more companies accept BTC, we'll need to ensure their business systems have integrated support both for the end customer, and in the back office. Many customers have a hard time managing multiple fiat currencies let alone BTC.
I need your help. I need to write a functional spec to give to my coders. They're smart, but don't work well without a framework.
Do you have an accounting background? Do you have some ideas on what an ecommerce platform would need to do to accept BTC? Please help.
Can you collaborate with me on a functional overview doc? Here's a link to the doc. Edit away. I'm relying on the awesomeness of the internet to generate some ideas.
https://docs.google.com/document/d/1HFPbSEPws8V5EOziu_ANbNmjqS-DE4Kl9IE-HbrRpEk/edit?usp=sharing
If I can flesh out a decent spec, we'll give implementing it a go. If it works out, we'll have, perhaps 12,000 companies that could install this and accept BTC if they wish. It'll also, hopefully get my big vendor talking about BTC to the accounting world.
If it works out, I'll sell this app to them for BTC only. And cheaply so that cost is not an issue.
If you have other ideas for where integration with accounting needs to be, please comment below, or ask questions.
I created this as a non-identifying account as I'd like to keep my company and the software we support private until we get going on the idea. I will go public when we have something to talk about.
And if you just want to encourage us. 15w46FNAsovtj9EQ5bhxQ99g9xDM65dJ3T

[uncensored-r/Bitcoin] /r/Bitcoin FAQ - Newcomers please read

The following post by BinaryResult is being replicated because some comments within the post(but not the post itself) have been silently removed.

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV.
Key properties of bitcoin
  • Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary.
  • Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable - The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
  • Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
  • Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
  • Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
  • Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
  • Nearly instant - From a few seconds to a few minutes depending on need for confirmations. After a few confirmations transactions are irreversible.
  • Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
  • Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable - Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
  • If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
  • If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy
Android Android
iOS iOS

There are also lots of charities which accept bitcoin donations, such as Wikipedia, Red Cross, Amnesty International, United Way, ACLU and the EFF. You can find a longer list here.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
  • 1-3% savings over credit cards or PayPal.
  • No chargebacks (final settlement in 10 minutes as opposed to 3+ months).
  • Accept business from a global customer base.
  • Increased privacy.
  • Convert 100% of the sale to the currency of your choice for deposit to your account, or choose to keep a percentage of the sale in bitcoin if you wish to begin accumulating it.
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.

Bitcoin wallets are inaccessible for blind people

So I am a fully blind person who uses a screen reader and every bitcoin wallet I have downloaded (Bitcoin QT, Multibit, Armory) are inaccessible to my screenreader.
This is making me very annoyed as I am a bitcoin supporter and I have acquired my own bitcoin I just cant god damn use them with out getting help from someone else. Multibit Is a java based wallet and as such, could have easily been made accessible if the Java accessibility JDk were included from the start. If we want bitcoin to truly be successful, this has to be dealt with. Any ideas outhere in the readit ethos??
Oh and by the way, when I signed up for readit, I had to fill in a visual captia (which I had to get someone to help me) and as if that was not enough, for posting in this readit forum, I have to get someone to help me fill in another visual captia before I submit. I was going to donate some bitcoin to this forum, but obviously that is a little bit hard when I cannot even really access my bitcoins from my wallet. Kind of makes me not wan to donate now.
Does anybody know of a wallet that would be accessible to screenreaders?
yIf there is not one, does any one know a developer that would take some time to build or develop one? I am sure it would not be all that hard if lets say an open source, java based wallet were redeveloped to include the accessibility JDK/API.
Thanks '
Okay I am going to append a couple of comments to this if I can figure it out:
first thanks for the amazing response!
Second, although I have been creeping the Readit Bitcoin forums for a while, I have never actually posted or interacted and have only been a member for a couple of days so I am a bit clueless as to how to engage the forum and I think I actually posted this same post (above) a fewe times by accident (sorry).
So in response to to some of the comments in general, I am a marginally technically capable blind screen reader user, and as such do not mind spending the time to learn anyway that will help me access the bitcoin technology. That being said, part of the reasoning behind making wallets accessible is so that people who are not technically inclined ( blind or not blind) will be able to more readily access Bitcoins and as such, adoption and uptake will be more fricktionless making the technology more appealing. accessibility for the blind and usability for the sighted are two sides of the same coin in that one compliments the other.
in term terms of the braille suggestions, I am interested, however I only started learning braille recently and I am only in grade one as I have been blind for only five years, so I have a ways to go in that regard.

Why the Segwit2X hardfork will fail

Why the Segwit2X hardfork will fail
"Its time-frame is extremely absurd. Actually, absurd doesn't do it justice which is why between that and number #1 several engineers have been just responding "LOL" to the proposal. They don't set any time for design review and analysis, they don't set any time for writing a specification (they don't have one and don't appear to intend to have one), they set aside two weeks for testing-- which is less time than even minor releases of Bitcoin get (and need!) even when they were comprised of small fixes which had mostly existed for months already. They don't allot any time for alternative implementations to implement it (which is especially bad because they can provide useful design feedback). They don't set aside time for meaningful deployment by users (some of whom may have their own lengthy patching and qualification process). They don't seem to have any concern about how forced upgrades erode decentralization and privileged hosted wallets/apis/pools over running your own infrastructure. Basically every stage of the consensus rule change pipeline should take (and always has taken) more time they allotted for everything. BU+Classic BIP109 ran on testnet for months before their interoperability failure was revealed and they forked apart from each other and abandon BIP109."
Now, let's assume for a moment that 80% of the hash power runs this fork as well as some of the economic ecosystem that signed the New York agreement like Abra, Bitpay, Coinbase, Blockchain, Purse, Shapeshift, Xapo, etc. What would happen? First, a large number of users and other parts of the ecosystem might not support it. There are many economic parties that were not part of the agreement, such as wallets like Trezor, MyCellium, Armory, Bitcoin Wallet (Android), Green Address, Breadwallet, Electrum, etc. There were a lot of exchanges that weren't part of the agreement, like Kraken, Poloniex, Bitstamp, Gemini, Bithumb, Bitfinex.
What if several of those mentioned major economic players decide not to support Segwit2X and don't run the Segwit2X/btc1/NY client? I believe what would happen in that scenario is the following:
An important point to keep in mind is that nearly every core developer has at one point in time supported the idea of a hard fork and even larger blocks. But what they haven't supported is doing it without a high degree of consensus on forking safely, without the best research, lots of testing, and a very long time horizon.
If we truly want to hard fork Bitcoin, we need to do it wisely, following the very challenging but necessary process for making such critical consensus changes. And it needs to be done with an open community process, not with a New York style agreement that leaves out major parts of the ecosystem. Bitcoin core is not the enemy of hardforks, or even block size increases. But there has to be very good justification for making these changes, a high degree of consensus and buy-in from the whole ecosystem, lots of research, good code, lots of testing, and a compelling need. It's a high bar, but not impossible. While there exists methods of getting more scale with safer methods (Schnorr signatures, bi-directional payment channels, transaction cut-through, extension blocks, lightning, flex caps, drivechains, etc.) hard forks seem less compelling for the moment.

PSA: "My bitcoin got stolen" is now a daily post here. Use paper wallets, only keep 5% of your bitcoin online. More security analysis in this post.

Almost all bitcoin thefts happen because of trojans, compromised Windows machines.
The scenario is eerily repeating: User logs on to Mt.Gox or another exchange or online wallet and does some transactions. While they are online, their compromised browser inserts an API key into the service. A few hours later, after logging off, they get an email: "Your funds withdrawal has completed!". Their bitcoin is stolen, nothing they can do, gone forever.
This will keep happening, again and again. Bitcoin trojans are now common - it makes sense, this is money and easy to steal
Here are a few things that DON'T HELP:
Here's what DOES HELP:
What you should do ANYWAY, on clean OS and offline:

Need some advise/help according development on bitcoin/ethereum.

Hi everyone!
I am looking and trying to create my own project, which would accept BTC and ETH. I successfully created deposit module to both blockchains (to let users be able make deposits), which is working pretty good, but I should notice - info is not gathered from blockchain and I dont have full nodes anywhere.
Now I want to create withdrawal module - again, for Ethereum and Bitcoin. Main issue is that I do not really know how could I create/sign transactions on those blockchain, without downloading full node. Like there are some wallets (bitcoin core, armory) and even online services (for airgapped pcs) on blokchain.info and myetherwallet.com, but they do not have any API or either they require full node. I am simply looking for some algorithm/tool which will let me create and sign transactions with my private keys, so then I would be able to broadcast them.
Any kind of help is really appreciated,Thanks!

Difference between ChromaWallet and CoinPrism colored coin wallets

I am the lead developer of ChromaWallet colored coins wallet, and after CoinPrism release people often ask me about relationship between these two projects, compatibility, differences and so on. Apparently there is a substantial degree of confusion, so I'd like to clear things up in this post.
First of all, these two projects are completely independent.
ChromaWallet is essentially a descendant of colored coin initiatives which started in 2012, we went through several prototypes (ArmoryX, WebcoinX, etc) until we started NGCCC project in June 2013, and now NGCCC evolved into ChromaWallet. It is completely open source from day one, development process is open (you can see 11 contributors here), and we created reusable components (coloredcoinlib, ngcccbase) which can be used in customized wallets and applications.
CoinPrism is a new project, AFAIK it started in 2014. No source code was published so far.
Of course, for end users features matter more than a development process, so let's go through substantial differences:
Compatibility: currently ChromaWallet and CoinPrism use different "color kernels", so they are not compatible (although future versions might be).
Other features:
Development status:
ChromaWallet version 0.0.7 was released few days ago, it is the first version with enabled SPV, and it seems to work. But it definitely needs more testing before I can recommend people to use it in production.

Dev Meeting Notes, 2016 08 22

#namecoin-meeting notes, 2016 08 21 # Present: Jeremy Jonas Brandon Midnightmagic Pigeons Joseph Namecoin Core The wallet name operation bug in Brandon's name tab PR has been isolated by Jeremy. Appears to be a bug in upstream Bitcoin Core (or perhaps Namecoin Core master branch) that has been fixed. https://github.com/namecoin/namecoin-core/pull/67#issuecomment-231316792 Whit Jackson submitted a documentation PR for building on OS X. https://github.com/namecoin/namecoin-core/pull/97 If anyone can test, please do so! Jonas will test this. Jeremy noticed that Travis CI accidentally flagged our repo as "potential abuse detected". Jeremy contacted Travis CI support and got our account whitelisted. Jonas notices that the Travis CI builds for our 0.13 branch are failing at the moment. Jeremy suggests filing a GitHub issue. Jeremy asked Jonas to submit a PR for Gitian builds for OS X. https://github.com/namecoin/namecoin-core/issues/38#issuecomment-236101580 DrHaribo of BitMinter requested that getblocktemplate be re-added to Namecoin Core. https://github.com/namecoin/namecoin-core/issues/98 Jeremy points out that since nVersion=4 blocks are nearing the lock-in point, we should deal with this sooner rather than later so that BitMinter doesn't get kicked off the network. Brandon asked on GitHub about how wallet unlocking should be done with the name tab GUI. https://github.com/namecoin/namecoin-core/pull/67#issuecomment-240852324 Upon discussion, Brandon currently plans to try using the raw transaction API for this. Daniel submitted a PR to temporarily disable the low-S standardness check. This should improve confirmation times for the old 0.3.80 clients. The check will be restored after AAA activates. https://github.com/namecoin/namecoin-core/pull/100 Test reports would be great. Jeremy points out that this needs to be done before nVersion=4 blocks are locked in. Jeremy wonders whether we should cancel plans to release 0.12 as stable, and focus on 0.13 branch. Tentative plan: keep maintaining 0.12 until Bitcoin Core releases v0.13.0; backport the name tab to whatever stable branch exists at the time that it's merged to master. SPV Jeremy's initial PR for Namecoin support has been merged to libdohj. https://github.com/dogecoin/libdohj/pull/18 Jeremy still needs to rebase the bitcoinj-addons code based on the libdohj changes made during review, and then submit a pull request. In the meantime, Jeremy's latest bitcoinj-addons and libdohj code is posted. https://forum.namecoin.org/viewtopic.php?p=16788#p16788 Someone please test it? Jeremy asks if he should post a link on Reddit. Jonas says yes. Jeremy will do so. ncdns Jeremy asked about the old fork of a Conformal library (see previous meeting); Hugo doesn't recall details but thinks it had to do with pre-Namecoin-Core not following spec properly. Hugo would be happy to accept a PR to make it use the current Conformal libs. https://github.com/hlandau/ncdns/issues/12#issue-163964219 Jeremy pointed out that sometime in the future we should fix the Extended Key Usage Critical flag on the dehydrated cert template. Go's standard library doesn't have a built-in way of setting that flag, which is why it's not in the first draft. Jeremy and Ryan can't think of any plausible attacks where it matters. Jeremy suggests a 1.0 BTC bounty for an ncdns NSIS installer. Possibly funded 50/50 by NMDF and a fundraiser. https://forum.namecoin.org/viewtopic.php?f=18&t=2566 Mining Cassini noticed that BTCC and ViaBTC have started mining Namecoin. https://forum.namecoin.org/viewtopic.php?p=16703#p16703 This is good news for mining diversity. F2Pool's share of Namecoin blocks is down to circa 43% as of July 26, 2016. Public Relations Cassini represented us at GETD#4 in Berlin July 22-23. Jeremy mentions that we should think about translation workflow. https://github.com/namecoin/meta/issues/35 Jeremy notes that Bitcoin Core is using Transifex. https://github.com/namecoin/namecoin-core/blob/mastedoc/translation_process.md Jeremy says that whatever works for Bitcoin Core, should probably work for us. Midnightmagic concurs. Joseph believes that Armory (post-ATI) is trying Transifex. Brandon asks what the pricing looks like for Transifex. Joseph believes it's gratis for open-source projects. Jeremy notes that Wikipedia confirms this. Jeremy wonders what safeguards are in place on Transifex to reduce risk of malicious translations. Joseph isn't sure. Jeremy points out that the way we organize the list of exchanges doesn't make sense for decentralized exchanges like Bitsquare. https://github.com/namecoin/namecoin.org/issues/70 Jeremy suggests listing decentralized exchanges at the top of the list. Jeremy notes that this might annoy the centralized exchanges who pay us for placement, but that this doesn't bother him at all. Midnightmagic concurs. Pigeons mentions that he's seen an increase in Namecoin offers on Bitsquare recently. Jeremy will have a table at the OU CS welcome party on Sept. 9. Let's try to recruit some developers! Brandon asks what the status is of the students from last year. Jeremy is sad to report that the SPV student and the UX student from last year are not participating this semester. Pigeons says a "Namecoin vs Blockstack" FAQ entry would be helpful. Jeremy will work on it. Midnightmagic asks if a meetingbot would be welcome. Jeremy says yes. Midnightmagic will look at setting one up. Funding Jeremy has filed a complaint with Tip4Commit about their usage of CloudFlare CAPTCHAs. https://github.com/tip4commit/tip4commit/issues/300 Tip4Commit has not responded after 25 days. BountySource balance: $5/month from 1 recurring supporter Total funds available: $304 USD Pigeons suggests looking into Patreon. Jeremy notes that they have CloudFlare CAPTCHAs. Jeremy notes that Wikipedia says they take a 5% commision, which is half of BountySource's 10%. Jeremy notes that some free software projects use them currently. https://www.reddit.com/linux/comments/33dp6n/should_open_source_projects_use_patreonkickstartecqkrlkf Jeremy will look into this in more detail later. NMDF incoming funds: 0 mBTC received since 2016 07 03 0 NMC received since 2016 07 03 Pigeons suggests looking into Flattr. Jeremy notes that they have CloudFlare CAPTCHAs. Jeremy notes that Wikipedia says they take a 10% fee (same as BountySource). Jeremy will look into this in more detail later. 
Note: I made a typo in the title of this post on Reddit; the quoted date of the meeting is correct. (I can't see a way to edit the title of a Reddit post.)

I can not sweep my Armory wallet address to counterparty

I am trying to use some coutnerparty tokes, years ago I moved tokens/coins to cold storage in Armory, but the backup format is base58 but the coutnerwallet needs a seed. I created another wallet and attempted to sweep the old address but the api is saying insufficient bitcoins to sweep address. I have sent almost $500 worth of bitcoins to the address but the wallet is still saying insufficient coins to sweep wallet
How can I get access to my counterparty tokes without spending hundreds of dollars worth of bitcons on fees?

Bitcoin Payroll: Centralized vs. decentralized solutions

Some bitcoin payroll solutions I've found that fall clearly in the "centralized" category are:
Bitwage - https://www.bitwage.com/ (individuals/employers)
Bitpay - https://bitpay.com/bitcoin-payroll-api/ (employers only)
Wagepoint - https://wagepoint.com/ (individuals/emps US/Canada)
Not decentralized, and not a payroll, but does keep its hands off your funds Coinsimple: https://coinsimple.com/ (Processor)
In the decentralized category, what I've found are: (Not actual bitcoin payroll, but rather, decentralized payment processor or plugin solutions)
Bitcoin Payments for Woocommerce: https://wordpress.org/plugins/bitcoin-payments-for-woocommerce/ (Plugin)
CoinKite's: https://github.com/coinkite/coinkite-real-time-invoice (Processor)
https://ck-rt-invoice.appspot.com/
Mycelium's: https://github.com/MyceliumGeastraight-server (Processor)
or just use https://gear.mycelium.com/
To answer the inevitable question, I have not found any software repository on github which holds itself up as an example of a decentralized bitcoin payroll solution explicitly. If you've seen one, please leave a link to it in the comments.
Edit: If you're looking for stuff that's a decentralized exchange (you know, to exchange one currency for another), I recommend Mycelium LT or Bitsquare. Both are now entirely functional and have been working very well for some time. If you are looking for a wallet, try Electrum, Mycelium, Core, Armory, or Trezor (the latter being a hardware wallet) -- DO NOT use web wallets.

Working on a program to expand Bitcoin-Qt's capabilities.

Originally posted about it here but it got overlooked (or nobody cared) -- thought it might fare better here.
Essentially it acts as a layer on top of Bitcoin-Qt. It needs to run at the same time, like Armory, but unlike Armory it is not a wallet in its own right, and it doesn't take forever to start up and doesn't use a bunch of memory. It is just a graphical interface to some of the API functions.
Right now it doesn't do too much -- it just shows you which addresses have how many bitcoins. This ought to help a user understand how transactions work, and where fees are coming from (even if you set the fee to 0).
I intend to expand this over time, likely next focusing on some more complicated transaction types.
Any suggestions (including better names, since "advbtc" is a bit crap) would be nice.

BitContracts.org bounties

BitContracts.org is ready to award 10 BTC in bounties to project(s) which make use of advanced Bitcoin features. (Such as use of multi-signature transactions, other unusual ways of making transactions, etc. As of particular uses, check posts to this subreddit.)
It works this way: if you want to implement something cool, submit your proposal (reply to this thread). I will consider all proposals and select worthy ones, they will get funding. Say, if I see two worthy proposals each might get 5 BTC bounty upon completion.
I recommend trying to make a demo of some interesting feature. Implementation quality does not matter much, it's only important to demonstrate how it can work (of course, it should use tech correctly, faking it isn't OK).
Recommended platform:
  1. Electrum (Python, thin client, standalone)
  2. guts of Electrum (you can rip transaction-handling part out of it)
  3. script which uses bitcoind API
But other platforms are OK too. MultiBit, Armory, Bitcoin-Qt, etc.
Criteria: It should be an improvement over existing state. Say, it's already to possible to create multi-signature-using transactions and whatnot using bitcoind raw transaction command line interface (see examples), or via friendlier txtool. (Which is a good example of using bitcoind API from JS.)
I think friendlier user interface requires some communications between clients. E.g. merchant might upload tx details to some sort of messaging server and give customer a link, then customer's client can negotiate tx details through messaging.
Assistance: I will provide assistance in form of advice and whatnot, but, of course, people need to know what they doing, which requires some knowledge of Bitcoin protocol.
How to apply: I want to know
Goal: I want to continue development of perspective tools as part of BitContracts.org effort. I plan to get more funding for it, but it's not guaranteed.
And while we are at it, I'm looking for JS and Python developers to work on colored coins clients. This is unrelated to these bounties though, it's on a different budget, potentially much more money.

Decentralized exchange using a client that runs over QT

I don't know much about programming, but there has been a lot of talk about creating a decentralized exchange.
Would it be possible to create a client that runs over Bitcoin-QT (like how armory does) that could communicate to other clients over the p2p network to establish consensus on price?
It would need to integrate escrow functionality and communicate with a payment processor API. I like dwolla, but they charge a $.25 flat fee for accepting amounts over $10.

Working on an interface to Bitcoin-Qt's / bitcoind's API calls.

Right now, all it does that might be a bit handy is show you which addresses have how many bitcoins.
GitHub
Needed: python 2.7, wxPython 2.8
It is a bit rough at the moment, appearance-wise: a screenshot
I made this because the bitcoin-qt wallet does not have a way (that I've seen) to easily see all addresses, including un-labelled ones. There's the debug console, but that isn't really "easy", especially if you have a lot of addresses... I also use Armory, which will show you all addresses, but it is slow to start and a huge memory hog -- and it won't use the original client's wallet.
You'll need to set up the bitcoin.conf file to accept JSON-RPC commands (see this sample conf -- set server=1 and rpcuserpcpassword to whatever; this script will read them from the file)
It should work on Windows, *nix, and Mac, but I've only tested it in Windows.
If there's any interest, I might work on fleshing this out into a fuller interface. There's a lot of API calls that might be of use to someone.
PS: if you can think of a better name than "advbtc" please suggest it; I am terrible at naming things.

Bitcoin-Qt is the “Graphical User Interface” around the core Bitcoin protocol that is run by the majority of nodes on the network. ”bitcoind” is the same software but without the user interface — it is simply a process that runs in the background and only allows access to it through its API. For the purposes of running Armory, either one is sufficient, but one of them must be running. Armory Bitcoin Wallet is GPU-Resistant . The in-built GPU-resistant encryption protects your wallet’s encryption passwords. Thus, it disallows hacker attacks.
