Blockchain

Blockchain is a system in which a record of transactions, especially those made in a cryptocurrency, is maintained across computers that are linked in a peer-to-peer network. Blockchain was implemented in 2008 behind an anonymous person under the name Satoshi Nakamoto.

In 1982 David Chaum doctoral candidate at the University of California at Berkeley (California) outlined a blockchain database in his dissertation, “Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups." Decades later in 2008 on an online discussion forum, a related research paper appeared. The paper written by Satoshi Nakamoto was titled “Bitcoin: A Peer-to-Peer Electronic Cash System” and a year later the first blockchain was implemented.
