Consensus is reached through consensus algorithms (such as proof of work, proof of stake, etc.), ensuring the correctness and credibility of contract execution. The  decentralized verification mechanism reduces the possibility of single-node tampering or forging data, thereby improving the security and reliability of the data."}]}],"pr":"ddc9787629e16122d7af75c5f8252b0fd2c89bfbeee49fd5ddb8b31074c5b665"}
