The consensus mechanism is an algorithm used to reach  a unified agreement on the network state in a distributed network. It helps to verify and validate the information added to the ledger, ensuring that only genuine transaction records are stored on the blockchain. The consensus mechanism is responsible for safely updating the data state in a distributed network and balancing the relationship between efficiency and security.↵↵In a blockchain system, the role of the consensus mechanism is to ensure that all nodes follow the same rules when processing transactions and recording data. The consensus mechanism can be divided into two types: one is the consensus algorithm for ordinary errors (such as Paxos, Raft, etc.)"}]}],"pr":"ca978c27a37aced453eecde04a3df9fca37aa1996f7ae801bcd429f24886f61e"}
