CurrencyFair

An e-commerce business allowing payments and money transfers to be made through the Internet.
CurrencyFair can convert funds added from your bank account to a growing number of foreign currencies. The converted funds can then be transferred to a beneficiary account that you specify.
The service is available for both individuals and businesses.
This ability to send directly to the recipient's bank will likely make CurrencyFair a preferred method that will allow those purchasing bitcoins through a person-to-person marketplace, such as the Bitcoin-otc marketplace, to transact internationally.
Certain exchanges, such as Mt. Gox, may place restrictions on incoming bank transfers such that the name on the sender's account must be the same as name for the destination account at the exchange.
The service was launched in early 2009Currency Fair profile on CrunchBase. In 2010 a bitcoin community member contacted the service to request that the service add Bitcoin as one of the currencies supported though it does not appear that the organization has any plans to do soCurrency Fair.
Bitcoin Money blog covered CurrencyFair in July, 2011CurrencyFair: Bitcoin’s Arbitrage Helper.

Current Network Status

Bitcoins day to day functionality depends on the peer to peer network. This is just a collection of bitcoin clients running on various machines across the internet. The health of that network is critical to the functioning of the bitcoin currency.
===Total Number of Bitcoin Clients===
There are currently as of September 2011 approximately 60,000Sourced from BitcoinStatus, web site displaying numerous stats on the bitcoin network. active clients. We know this because as part of the protocol every client broadcasts their address across the network every 24 hours. By listening for these broadcasts and counting the number of unique addresses we can count the number of clients.
===Number of Listening Bitcoin Clients===
One of the issues that the peer to peer network faces is the fact that most users of the internet use machines that are behind a Firewall/NAT gateway. This means that they are only able to make outgoing connections to hosts on the internet and not receive incoming connections (unless they manually or automatically - using PnP - configure their firewall). There are over 12,000 bitcoin clients that can be connected to. This figure is be an underestimate of the actual number of hosts that are not behind a firewall as each host is configured to only accept 125 connections, and so if they are full we would not know if the host was behind a firewall or just ignoring out connection request due to too many connections.
===Ratio of Listening to Total Number of Hosts===
All hosts are configured to make 8 outgoing connections. With this and the fact that there is a limit of 125 total connection it can be concluded that once the ratio of total hosts to listening hosts approaches 15 there will be issues with hosts being unable to connect to the network. As of September 2011 this ratio is between 4 and 5 so is not an issue.
===Block Chain Availability===
In order for the network to be stable the current blockchain must be downloadable from the majority of clients on the network. As part of the handshake when a client connects to another client it informs them of the length of blockchain that it has. Currently (September 2011) the network has over 10,000 clients that are listening and have an upto date version of the blockchain. Should this number drop significantly (e.g. due to a network partition or DDOS attack) there would be issues in ensuring that all clients agreed on the current best chain.

Cwallet

A tool used to easily and securely create a paper wallet. It is designed to work with the Pirate Linux live disc (version 2.0 alpha 3).
What makes it different from the other paper wallet solutions?
- Pirate Linux does not use Ubuntu, but instead hardened Gentoo, regarded by many as the most secure operating system.
- Cwallet does not use a web browser. It is coded in pure C, and has both a graphical (gtk+) and command line interface.
- Cwallet uses only real random numbers from /dev/random and asks you to shake your mouse if it stalls and needs more entropy.
- Cwallet uses one-time-pads for encryption of the private keys. The passphrase is converted to a base-256 one-time pad that is byte-wise added to the base-256 private key.
- Cwallet performs many robust checks to make sure that the data that you print out is correct and not corrupted in the process. The last thing you want is to find out that you have the wrong private key for the address you sent your funds to.
- Cwallet has some other nice little features to make it easier to use.

DOS/STONED incident

On May 15, 2014, a virus signature of an antique virus called DOS/STONED was inserted into the block chain. This caused Microsoft Security Essentials to recognize the block chain as the virus, prompting it to remove the file in question, and subsequently forcing the node to reload the block chain from that point, continuing the cycle.https://answers.microsoft.com/en-us/protect/forum/mse-protect_updating/microsoft-security-essentials-reporting-false/0240ed8e-5a27-4843-a939-0279c8110e1c?tm=1400189799602&auth=1http://www.theregister.co.uk/2014/05/18/bitcoin_user_stoned_on_virus_warnings/
Stoned was a virus created by an unidentified student from Wellington, New Zealand in 1987."...a brief history of PC viruses.", IBM Research"The early days", History of Malware It was one of the first computer viruses, and had become common and widespread by the 1990s. When an infected computer started, there was a one in eight probability that it would declare "Your PC is now Stoned!""Analysis of Stoned", Peter Kleissner"The “Stoned” PC Virus", Commented disassembly of virus code at computerarcheology.com The phrase is found in infected boot sectors of infected floppy disks and master boot records of infected hard disks along with the phrase "Legalise Marijuana".
Only the signature of the virus had been inserted into the blockchain; the virus itself was not there, and if it were, it would not be able to function.
The situation was averted shortly thereafter, as Microsoft had prevented the block chain from being recognized as Stoned.http://thehackernews.com/2014/05/microsoft-security-essential-found.html Microsoft Security Essentials did not lose the ability to detect a real instance of Stoned.

DarkWallet

DarkWallet is an experimental, privacy-focused bitcoin client initially developed by Amir Taaki, Cody Wilson and others.
The software is written in JavaScript and runs as an extension for Google's Chrome browser.
The project gained significant media attention for its use of modern BIP 0032 wallet format and privacy-preserving features such as Stealth Payments, and passive CoinJoin mixing, development on the project has waned and it appears to be abandoned. The last release was Darkwallet Alpha 8 (announcement on wiki) on Jan 23, 2015. 
As of 2020 it's not really maintained anymore and JoinMarket, Wasabi and Samourai can be considered reasonably useful alternatives.

Decoding BitPay payment requests

BitPay annoyingly forces users to pay via a non-standard version of the BIP70 payment protocol. BIP70 was created in 2013, and is deprecated due to its complexity, reliance on the insecure & centralized certificate authority architecture, privacy issues, and lack of compelling reasons to use it. Therefore, it is not widely supported by wallets, and it probably never will be. This page shows you how to pay to these requests without wallet support.
==Easy Way==
Paste the request URI into https://alexk111.github.io/DeBitpay/, and it will give you the address. This is slightly insecure, since that page could be suddenly changed to give you an incorrect address instead of the real one.
==Doing it yourself==
BitPay supports a non-standard extension to BIP70 which uses JSON instead of a binary format. Therefore, you can use curl or similar to get the payment info. Use a command like:
curl -H 'Accept: application/payment-request' https://bitpay.com/i/...
curl supports Tor and proxies. For Tor, you'd add --socks5-hostname localhost:9050 before -H. Replace 9050 with 9150 for Tor Browser.
In the response, address is the address you pay to, amount is the exact number of satoshi you are expected to send (divide by 100000000 for BTC), and requiredFeeRate is the minimum satoshi/byte fee rate that you must pay. Warning: if you don't pay at least the fee rate specified, then BitPay might not register your payment. Round your fees up if necessary.
It should be possible to use built-in tools such as PowerShell to do the same thing on Windows. Edit this page if you know how.

DeepBit

DeepBit was a mining pool. The site currently reports a hash rate of 0 Gh/sWeb site, many users report the pool as abandonedRe: (1.3 TH) DeepBit.net PPS+Prop,instant payouts, we pay for INVALID BLOCKS too and the last block seems to have been found on 28. November 2013Re: (1.3 TH) DeepBit.net PPS+Prop,instant payouts, we pay for INVALID BLOCKS too. The pool operator who opened the announcement / support thread on the BitcoinTalk Forum was last active on 16. March 2014View the profile of DeepBit.
This pool aimed to provide a simple reward sharing scheme and fast payments. It was once the biggest mining pool and at one point had more than 50% of the overall hash power at the timedeepbit has 50.18 % now.
The service was first available for beta testing starting February 26, 2011New mining pool with proportional reward distribution.
==Reward distribution==
* Proportional: 3% fee.
* Pay-Per-Share mode: Current rate shown on website.
==ASIC hardware==
On September 10th, 2012, the owner of DeepBit announced plans for a custom Bitcoin mining ASIC termed Reclaimer.https://bitcointalk.org/index.php?topic=108375. On April 8th, 2013, cancellation of the project was announced, citing lack of public interest.https://bitcointalk.org/index.php?topic=108375.msg1767578#msg1767578

Development process

== Bitcoin Core Open Source Development Process ==
The Bitcoin Core project operates an open contributor model where anyone is welcome to contribute towards development in the form of peer review, testing and patches.
Bitcoin Core has transitioned from what was essentially a one-person software endeavor, with Satoshi functioning as the primary developer and gatekeeper for all changes, to a more distributed, free software model of development with hundreds of contributors. The Linux Kernel development process is being used as the model for how changes flow into the original Bitcoin application:
# Developers work in their own source code trees, sharing and testing patches with each other. Git, using github, is the preferred source control system for development.
# When a developer thinks a patch is ready, they submit a pull request for the bitcoin github repository and post a message on the Development and Technical Forum.
# Pull requests are discussed on the forums and if there is consensus they're safe, tested, useful, well written, match coding style, etc. then they're merged into the 'master' branch.
# The master github branch is regularly built and tested, and periodically given a "release candidate" tag followed by a version tag which is then an official, stable Bitcoin Core release.
# After being accepted into the mainline master branch, bugfixes are merged or backported into the current stable branch, which periodically releases stable older versions.
Please read and follow the Bitcoin Core Coding Standards document.
== How to get started ==
One of the best ways to dive into the code is to help review pull requests.
How to Review Pull Requests in Bitcoin Core is a great place to start reading about this. And the Bitcoin Core PR Review Club is a weekly event on IRC which helps newbies with this process.
