Problems solved by technology

[0004] In the pre-execution mechanism, because the clocks of different nodes are inconsistent, and there are reasons such as network delays, it provides developers of smart contracts with the ability to obtain time, that is, it is impossible to implement smart contracts that depend on time

[0047] figure 1 It is a flow chart of the smart contract-based data processing method according to the first embodiment of the application. This embodiment can be applied to the situation of invoking time-dependent smart contracts and processing transaction requests based on the pre-execution mechanism. This method can be configured in the area The data processing device based on the smart contract of the endorsement node in the block chain network is executed, and the device is implemented in the form of software and / or hardware. Such as figure 1 As shown, the method specifically includes the following:

[0048] S110. In the process of invoking the smart contract, determine the current time of the endorsement according to the time of the previous block in the endorsed blockchain.

[0049] Based on the pre-execution mechanism, the blockchain network determines at least one endorsement node. For example, in Baidu Super Chain, only one endorsement node is determined in a sing...

Abstract

The embodiment of the invention discloses a data processing method and device based on a smart contract, equipment and a storage medium, and relates to the technical field of block chains. According to the specific implementation scheme, in the process of calling the intelligent contract, the current endorsement time is determined according to the time of a previous block in an endorsement block chain; and the current transaction processing request is processed according to the endorsement current time to obtain an endorsement processing result, so that other nodes in the blockchain network process the current transaction processing request according to the endorsement processing result. According to the embodiment of the invention, in the process of calling the smart contract, the currenttime is determined according to the time of the previous block in the block chain, and the current transaction processing request is processed according to the current time, so that the time-dependent smart contract can be supported in the pre-execution mechanism.

Description

technical field [0001] The embodiment of the present application relates to the field of computer technology, especially to the field of blockchain technology, and specifically to a data processing method, device, electronic device, and storage medium based on smart contracts. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In the field of blockchain technology, smart contracts refer to computer programs that cannot be tampered with and are automatically executed. [0003] In some blockchain networks, such as Fabric and Baidu Super Chain, the smart contract is executed based on the pre-execution mechanism, that is, before the transaction processing request is packaged into the block, the transaction processing request is pre-executed through the endorsement node. The node processes the transaction processing request accor...
