Firstly, blockchain employs distributed node consensus algorithms to generate and update data, ensuring decentralization and security of the data. Secondly, blockchain utilizes cryptography to guarantee the  security of data transmission and access, preventing unauthorized tampering. In addition, smart contract programming and operation of data in blockchain technology can automatically execute upon satisfying specific conditions, thereby ensuring the correctness of transactions. Lastly, nodes in the blockchain network must reach a consensus to validate and record new transactions, ensuring the reliable propagation of transactions within the blockchain network. These mechanisms together guarantee the correctness of transaction execution in blockchain."}]}],"pr":"886e397a379129991e398b5f7d153dddc3488ad068425a6588ca79153d1b1d2b"}
