Bitcoin Core is open source -Referenzimplementierung the Bitcoin - cryptocurrency . It was originally published by Satoshi Nakamoto under the name Bitcoin and later renamed Bitcoin Core . The reference software validates the entire blockchain, including all transactions ever made. In addition, it has activated a wallet by default with which the user can carry out transactions. Bitcoin Core consists of the implementations bitcoin-qt (GUI, based on Qt ) and bitcoind (Bitcoin client without GUI).

History of origin

The Bitcoin network was created on January 3, 2009 with the creation of the first 50 bitcoins. A few days later, the first version of the Bitcoin reference software Bitcoin Core was published under the pseudonym "Satoshi Nakamoto" on the same mailing list as the white paper, at SourceForge and in the Internet discussion forum of the P2P Foundation . The first version of Bitcoin Core is written in the C ++ programming language, uses the program libraries wxWidgets , OpenSSL , Berkeley DB and Boost and contains program files for Windows as well as source code under the MIT license . At the end of 2009 , the Finn Martti Malmi ported the Bitcoin core software to GNU / Linux and supported Nakamoto in the development. Other developers from the open source community joined them later. Some of the developers, such as Jeff Garzik, also contribute to the Linux kernel . At the end of 2010 / beginning of 2011, Nakamoto withdrew from development and handed over the project management to Gavin Andresen. Today development takes place via Git , communication about changes takes place on Github . Many of today's developers are employed by Blockstream or Chaincode Labs.

development

Bitcoin Core is being developed by a large community. In August 2019, the project had over 638 contributors . Everyone has the opportunity to submit code, translation, tests, bugs or other improvements as a pull request on GitHub . These are then discussed. Everyone has the right to vote with either Concept ACK / NACK or Approach ACK / NACK . These terms come from the Internet jargon . Gets a pull request enough support, it will be from one of the six maintainer in the code merged .

Spin-offs

Due to the great disagreement of the community about the scaling of Bitcoin, there are several spin-offs of the software. These have or had the goal of increasing the block size limit in order to allow more transactions per time. The spin-offs Bitcoin XT, Bitcoin Unlimited and Bitcoin Classic did not reach the threshold for activating the hard fork due to insufficient support from miners. On August 1, 2017, Bitcoin Cash carried out the first controversial fork ("contentious fork") of the blockchain. Bitcoin Cash has increased the block size limit to 8 MB. Another hard fork was planned with Bitcoin SegWit2x and BTC1. Segwit2x increases the block size limit to 2 MB. The hard fork was postponed indefinitely on November 8, 2017 because there was no consensus.
