Bitcoin
Published in Sandeep Kumar Panda, Ahmed A. Elngar, Valentina Emilia Balas, Mohammed Kayed, Bitcoin and Blockchain, 2020
Bitcoin is an open-source mission, and MIT holds the license for its source code. Bitcoin Core can be downloaded for free. A community of volunteers had created the Bitcoin project. Initially, only Satoshi Nakamoto was there in the project. Later by 2016, it had around 400 contributors with a handful of developers and several part-time developers. Bitcoin Core can be regarded as the reference implementation of the Bitcoin system by Bitcoin since it is the authoritative reference on how to implement each part of the technology. It is labeled as the Satoshi client. Bitcoin Core acts as a Bitcoin node, and a collection of Bitcoin nodes form a Bitcoin network. Nakamoto initially released the “Bitcoin” software, but to make it different from the network, he later renamed it to “Bitcoin Core.” Bitcoin Core has all features of Bitcoins such as wallet, block validation engine, transaction, and full network node in P2P Bitcoin network.

Note that there may be a diversification in the peers in the blockchain network, depending on their function in the blockchain. For example, in the Bitcoin blockchain, one may have Full Nodes (which run the Bitcoin Core Client and store the entire Bitcoin blockchain ledger) or Simple Payment Verification Clients (SPVs, which only perform block and transaction validations). Each of the blockchain full nodes runs the same code and has the same copy of the ledger. As we will see in later sections, permissioned architectures may allow further diversification of peers into specialized roles to allow data compartmentalization.

In October 2008, Nakamoto introduced the first blockchain model to the world through a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System”.1 Then, in January 2009, the company unveiled the Bitcoin Core program, using the concept of “blockchain” to introduce its first cryptocurrency.
