METHOD FOR AUDITING SMART CONTRACT WITH MULTI LAYER AND APPARATUS THEREOF

摘要

The first smart contract audit department, which performs audits on smart contracts stored in bytecode, and SWC vulnerabilities that may be omitted from the first smart contract audit department, are compiled at the smart contract programming language level and stored as source code. Vulnerability of the smart contract by collecting the second audit report received from the second smart contract audit department, which performs an audit, and the first audit report received from the first smart contract audit department, and the second smart contract audit department. It includes a report and a vulnerability report unit that provides a smart contract with vulnerabilities supplemented, and the first smart contract audit unit reads the byte code from the stack in which the byte code is stored using a static single assignment (SSA) technique and into memory. A multi-layer-based smart contract audit device is provided that stores in a flat array and reads byte codes stored in a flat array in memory to perform audit on smart contracts.
