Abstract

The invention discloses an intelligent contract execution method and system in a blockchain, and electronic equipment. The method comprises the following steps: after a target proposal reaches a consensus, a blockchain node calls a smart contract to execute a target transaction in the target proposal, and stores a transaction execution result of the target transaction generated in an execution process in a first cache; if the target transaction is successfully executed, the blockchain node stores a transaction execution result of the target transaction stored in the first cache into a second cache; and the blockchain node performs a block writing operation based on the transaction execution result in the second cache.

Description

technical field [0001] This document relates to the field of computer technology, and in particular to a smart contract execution method, system and electronic device in a blockchain. Background technique [0002] During the execution of smart contracts in the blockchain, there is usually a problem of transaction rollback. For example, when a transaction calls a smart contract for transaction execution, the transaction execution may fail due to operational logic errors or gas exhaustion. Since the smart contract will modify the account status of both parties during the transaction execution process. When the execution of the transaction fails, the modification history needs to be rolled back, that is, the account status of the parties to the transaction modified by the smart contract is restored to the state before the modification. [0003] At present, in Ethereum, the operation log (change log) is usually used to record all modification records, and when the modification...
