The consensus mechanism achieves consistency of opinions across all nodes in the entire network, allowing smart contracts to automatically execute pre-set terms in a trustless environment, thus realizing the digital fulfillment of contracts without the intervention of third-party trust. At the same time, the consensus mechanism also ensures the data consistency, anti-tampering, and system stability in the blockchain network, enabling smart contract applications to run efficiently and securely worldwide."}]}],"pr":"8e780a0434320776bf94e5895d3c1cdeea81871f0c29954ddc5c2f522ab7404c"}
