Bitcoin Core is free and open-source software that serves as a bitcoin node (the set of which form the Bitcoin network) and provides a bitcoin wallet which fully verifies payments. It is considered to be bitcoin's reference implementation. Initially, the software was published by Satoshi Nakamoto under the name "Bitcoin", and later renamed to "Bitcoin Core" to distinguish it from the network. It is also known as the Satoshi client. Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full node.
The software validates the entire blockchain, which includes all bitcoin transactions ever. This distributed ledger, which has reached more than 608.9 gigabytes (not including database indexes) in size as of October 2024, must be downloaded or synchronized before full participation of the client may occur. Bitcoin Core includes a scripting language inspired by Forth that can define transactions and specify parameters.
The original creator of the bitcoin client has described their approach to the software's authorship as it being written first to prove to themselves that the concept of purely peer-to-peer electronic cash was valid and that a paper with solutions could be written. The lead developer is Wladimir J. van der Laan, who took over the role on 8 April 2014. Gavin Andresen was the former lead maintainer for the software client. Andresen left the role of lead developer for bitcoin to work on the strategic development of its technology. Bitcoin Core in 2015 was central to a dispute with Bitcoin XT, a competing client that sought to increase the blocksize.
Over a dozen different companies and industry groups fund the development of Bitcoin Core. In 2019, MIT announced donations of $900,000 would be used to fund the Digital Currency Initiative, which would mainly go to developers of Bitcoin Core.
