Abstract

The invention provides an intelligent contract fuzzy test method and device, and a storage medium, relates to the technical field of block chains, and is used for improving the security of an intelligent contract in a block chain and avoiding unnecessary loss. AST scanning analysis is carried out on the intelligent contract to generate an intelligent contract method protocol; in combination with an intelligent contract method protocol, mutation operation is carried out on the test case sample to generate test case mutation data, and the test case mutation data comprises a method name of the tested intelligent contract and a test case mutation sample; the method also includes requesting the test case variation data to a blockchain service, and determining a tested smart contract in the blockchain service according to the method name of the tested smart contract; and executing the test case variation sample on the tested smart contract, and collecting an execution result of the tested smart contract for the test case sample so as to determine a vulnerability of the tested smart contract according to abnormal data in the execution result.

Description

technical field [0001] This application relates to the technical field of block chain, and provides a method, device and storage medium for smart contract fuzz testing. Background technique [0002] Smart contracts are programs that execute on a blockchain network. Unlike traditional programs, smart contracts cannot be modified after they are deployed on the blockchain. Due to flaws in the development process of smart contracts, there are security holes in smart contracts deployed in blockchain services. At this time, anyone can attack the security holes in smart contracts, causing frequent security incidents in smart contracts, resulting in inevitable loss. Contents of the invention [0003] The embodiments of the present application provide a method, device and storage medium for smart contract fuzz testing, so as to improve the security of smart contracts in the blockchain and avoid unnecessary losses. [0004] In the first aspect, the embodiment of the present appli...
