Abstract

The embodiment of this specification discloses a transaction execution method, system and device. The method is executed by a block chain node, which includes: obtaining a transaction; executing the first transaction processing stage of the target smart contract to complete a part of the transaction processing flow, and obtaining a first processing result; triggering a verification program to verify the first The processing result is checked, so that based on the checking result, the second transaction processing stage of the target smart contract is executed to obtain the execution result of the transaction or terminate the processing of the transaction. In order to achieve the security monitoring of smart contracts and improve the security of smart contracts.

Description

technical field [0001] This specification relates to the field of blockchain technology, and in particular to a transaction execution method, system and device. Background technique [0002] In recent years, due to the openness of blockchain smart contracts, any tiny loopholes in them may be discovered and attacked by attackers, resulting in the low security of blockchain smart contract systems. Therefore, a method for smart contract security monitoring is needed to improve the security of smart contracts. Contents of the invention [0003] One of the embodiments of this specification provides a transaction execution method, and the method is executed by a blockchain node. The method includes: obtaining a transaction; executing the first transaction processing stage of the target smart contract to complete a part of the transaction process to obtain a first processing result; triggering a verification program to verify the first processing result, so that based on the ver...
