Nakamoto consensus is the Consensus Algorithm
used within the Bitcoin Blockchain
On the Cryptography mailing list, Satoshi Nakamoto claimed that the Proof-of-Work chain is a solution to the Byzantine Generals Problem.
Satoshi Nakamoto’s proposed solution to the BGP has since come to be known as ‘Nakamoto consensus’ which is the following summarized protocol:
- Always use the longest history.
- Appending a block to any history requires a proof that a certain amount of work – proportional in expectation to the total ‘capability’ of the network – has been completed.
