The consensus mechanism is the process by which nodes in a blockchain network reach a consensus opinion,  which is used to verify and record new transactions. In a blockchain system, after a node receives a proposal, it will analyze and verify it. After the verification is passed, the node will add the proposal to its local blockchain and send it to other nodes for consensus voting. During the voting process, the node will compare the voting results of different nodes according to the requirements of the consensus algorithm. When the consensus threshold is reached, the proposal will be confirmed and added to the global blockchain. This process ensures the consistency and security of blockchain data, while avoiding the risks of centralized control."}]}],"pr":"2748aa29e485b8c472bfa63e62f426db179dce219a6db19d7fb5c45e7595b523"}
