Back in August 2008, the domain name Bitcoin.org was registered and later that year, the website linked to a paper titled “A Peer-to-Peer Electronic Cash System” by author Satoshi Nakamoto. This paper detailed a peer-to-peer based network that generated what was said to be “a system for electronic transactions without relying on trust”.
The first block of Bitcoin was mined by Satoshi Nakamoto himself (block number 0) and the reward was 50 Bitcoins.
The earliest supporters of Bitcoin was programmar Hal Finney, who adopted to, supported and mined Bitcoin starting from the day of release. He received 10 Bitcoins from Nakamoto and the first transaction occurred in January 2009.
