Abstract

The embodiment of the present invention discloses a smart contract security vulnerability detection method, device, terminal and storage medium, wherein the method includes: constructing a grayscale image matrix according to a bytecode file; transforming the grayscale image matrix into a grayscale image; extracting grayscale The features of the grayscale image are input into the preset security vulnerability identification model to detect whether there are security vulnerabilities in the bytecode file. By implementing the application, the security loopholes existing in the smart contract can be detected, and at the same time, the detection accuracy of detecting the security loopholes can be improved.

Description

technical field [0001] The present invention relates to the technical field of computer security, in particular to a method, device, terminal and storage medium for detecting security loopholes in smart contracts. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is a technical solution for decentralized trust and collective maintenance of distributed ledgers. In essence, multiple nodes collectively participate in data storage and multi-party computing. A distributed data system that cannot be tampered with and whose calculation results are credible. Blockchain is not a single technology, but the result of the integration of multiple technologies. Using blockchain technology to maintain a reliable and difficult-to-tamper ledger record can reduce the risk of trust and effectively reduce the risk of public participation. Collaboration maintenance costs. The continuous development and improvement of blockchain technology makes s...
