Smart contract execution constraint method and device, terminal and storage medium

Abstract

The invention provides a smart contract execution constraint method and device, a terminal and a storage medium. The method comprises the following steps: determining a target user sending a transaction request and a transaction requested by the target user, wherein the target user is an enterprise user; obtaining first permission information pre-assigned to the target user by a target enterpriseto which the target user belongs; determining an execution constraint condition of a business method for executing the transaction in a smart contract provided by the target enterprise, wherein the execution constraint condition comprises second permission information of the target enterprise for an enterprise user allowed to execute the business method; and determining an execution constraint result of the smart contract on the transaction request according to the first permission information and the second permission information. An enterprise transaction scene can be realized, and the service security can also be improved.

Description

technical field [0001] The present invention relates to the technical field of block chain, and more specifically, relates to a method, device, terminal and storage medium for executing constraints of smart contracts. Background technique [0002] The core functions of the blockchain are packaging, consensus, bookkeeping, etc. At present, the blockchain usually serves transactions between individuals. For this kind of business interaction, the blockchain supports the operation of smart contracts customized by individuals. The business logic of the transaction is realized by the smart contract, which only requires unilateral approval by both parties to the transaction. That is, as long as the transaction initiator signs, it can be considered to meet the constraints of the smart contract and then execute the smart contract. [0003] This method of executing smart contract constraints not only has limited transaction scenarios and can only serve transactions between individual...

AI Technical Summary

Problems solved by technology

[0003] This method of executing smart contract constraints not only has limited transaction scenarios and can only serve transactions between individuals, but also triggers the execution of smart contracts as long as the transaction initiator signs, which means that anyone who provides the transaction initiator’s signature can Can run smart contracts and run business methods in smart contracts, which will bring great business security problems
