Abstract

The invention provides a smart contract security detection method and device based on a blockchain, a computer readable storage medium and electronic equipment. The method comprises the steps of obtaining a target smart contract and a file size thereof; obtaining each function from the target smart contract; obtaining and recording an initial-order parameter change relationship of each function; generating a first-order parameter change chain according to a change relationship between at least two parameters in the first-order parameter change relationship of each function; obtaining a targetparameter name in the target smart contract according to the file size; and traversing the target parameter name in a primary parameter change chain, and determining the tracking correctness of the primary parameter change chain according to the target parameter name to obtain a security detection result of the target smart contract. According to the technical scheme provided by the embodiment ofthe invention, the parameter change process of the target smart contract to be uploaded to the target blockchain can be correctly tracked, and the security of the target smart contract finally uploaded to the target blockchain is ensured.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a blockchain-based smart contract security detection method and device, a computer-readable storage medium, and electronic equipment. Background technique [0002] With the development of blockchain technology, blockchain technology is applied to more and more fields. For example, it has been widely used in the fields of finance, information security, computing resource sharing, entertainment, social networking, supply chain management or medical treatment. [0003] Among them, blockchain is a new application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. As a programmable blockchain, its main feature is to allow users to write sophisticated and intelligent agreements, also known as smart contracts. [0004] A smart contract is a contract program that is automatically execut...
