Abstract

The invention relates to a method, a device and equipment for detecting vulnerability of a smart contract. The method comprises the following steps: acquiring a to-be-detected contract file; obtaininga logic expression corresponding to each terminal node in the to-be-detected contract file according to the operation logic of the executable code in the to-be-detected contract file; detecting eachlogic expression to obtain a detection result; and judging whether the contract file to be detected has a vulnerability or not based on the detection result. According to the method, the logic relationship in the to-be-detected contract file can be detected, and known or unknown vulnerabilities in the to-be-detected contract file can be detected without depending on known vulnerability feature information, so that the detection accuracy during detection of the vulnerabilities of the to-be-detected contract file can be improved, and various vulnerabilities can be detected, so the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of block chains, in particular to a detection method, device and equipment for loopholes in smart contracts. Background technique [0002] The blockchain is a distributed shared account book and database, which has the characteristics of decentralization, non-tampering, traceability, and traceability. The blockchain can solve the problem of information asymmetry and realize collaboration, trust and cooperation between multiple subjects. Acting in concert, these features enable the blockchain to be applied in a variety of scenarios. Ethereum (Ethereum) is an open source public blockchain platform, which has the characteristics of decentralization, consensus, and distributed ledger of blockchain. It provides all developers with a smart contract solution platform based on the Solidity language. It provides various modules for users to create smart contracts for their own projects. A smart contract is a computer protoco...
