…By creating a standard measurement for the blockchain’s validity — in this case, the amount of computational resources (or ‘hashing power’) spent on it — Nakamoto opened a new direction for solving the Byzantine Generals Problem in a permissionless setup; one that would lead to the emergence of many new consensus algorithms, including Proof of Stake (PoS), Proof of Authority (PoA), Proof of Reputation (PoR), and Proof of Importance (PoI). Proof of X The idea behind this proof of someth…

…We introduce three below: Nakamoto, Classical, and Leaderless. Nakamoto Consensus Mechanisms Satoshi Nakamoto’s PoW consensus mechanism opened up a new direction for solving the Byzantine Generals Problem in a permissionless setup. Following the development of the PoW consensus mechanism, many new consensus algorithms emerged. These include Proof of Stake (PoS), Proof of Authority (PoA), Proof of Reputation (PoR), and Proof of Importance (PoI). In general, these are categorised as Nakamoto con…

…These mechanisms aim to make the system fault-tolerant. To learn more about the underlying principles of blockchain and the challenges of achieving consensus in a distributed, decentralised system, read What Is Blockchain? From the Byzantine Generals Problem to Consensus. What Is Consensus in Blockchain? Consensus is the process by which a group of peers — known as ‘nodes’ — on a network determine which blockchain transactions are valid and which are not. Consensus mechanisms are the met…

…The decentralised nature of blockchains means that nodes on the network must be able to come to an agreement (i.e., consensus) as to the shared state of the blockchain. Learn all about blockchain — from the Byzantine Generals Problem to consensus — in our University article What Is Blockchain? The Function of a Fork In the world of cryptocurrencies, a fork is more often used to implement a fundamental change or create a new asset with similar (but not equal) characteristics as the original. …
