The invention discloses a blockchain operation method, device and equipment and a storage medium, relates to the technical field of blockchains, and can be applied to the field of cloud computing andcloud services. The specific implementation scheme is the method comprises the steps: in response to a pre-execution request initiated by a client based on a target smart contract, calling the targetsmart contract to execute the pre-execution request to obtain a pre-execution result; signing the pre-execution result according to the account key of the client to obtain a first result signature; and feeding back result data including the pre-execution result and the first result signature to the client, so that the client executes the following operations: initiating a verification transactionrequest to the verification node based on the result data, and enabling the verification node to verify the pre-execution result based on the first result signature. The verification efficiency of theoperation result of the smart contract is improved, and the method can adapt to different blockchain systems and has universality.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to block chain technology, and specifically to a block chain operation method, device, equipment and storage medium. Background technique [0002] In the blockchain system, after the blockchain node processes the transaction request and obtains the transaction data, it will transmit the transaction data to other nodes for verification to ensure the decentralization and security of the blockchain. [0003] However, the verification methods in the prior art have the problems of low verification efficiency or poor versatility. Contents of the invention [0004] The present application provides a block chain operation method, device, equipment and storage medium with higher efficiency and better versatility. [0005] According to one aspect of the present application, a blockchain operation method is provided, which is executed by an endorsement node, including: [0006]...
