Consensus Mechanism

A Consensus Mechanism is a fault-tolerant method used in decentralized computer networks, such as blockchains, to achieve the necessary agreement (consensus) on a single data value or the state of the network among distributed processes or multi-agent systems, ensuring that all participating nodes maintain an identical and secure copy of the ledger. These mechanisms are fundamental to solving the Byzantine Generals' Problem in a trustless environment, allowing for the validation of transactions and the addition of new blocks to the chain without the need for a central authority.
