The consensus mechanism is a consensus algorithm in the blockchain system, used to determine which node has the right to record accounts and receive corresponding rewards. In the Bitcoin system, a consensus mechanism called Proof of Work (abbreviated as PoW) is adopted. Under the PoW mechanism, miners compete against each other by comparing computer processing power and racing to solve a complex mathematical problem. The node that solves the problem first can obtain the right to record accounts and add new blocks to the blockchain.\n\nSpecifically, in the Bitcoin system, the implementation of the fixed reward mechanism mainly includes the following two aspects:\n\n1."}]}],"pr":"4db5b97828f777a520fb09f7e52acc9f8e37954e403d646ee7ce24c3645654fc"}
