Reverse Real-Time Model Detection of Chain Smart Contract Security Based on Association Method

Abstract

In the Internet age, user information is easily leaked and destroyed, and users are increasingly concerned about the privacy and security of information. If the smart contract itself has hidden security risks, it may threaten the user’s personal information and property security, and cause unpredictable losses. This article focuses on the security problems of smart contracts, based on the rules of association mining, and adopts a reverse approach to the intelligence in Ethereum Analyze the contract source code, extract the logical flow of the contract, and further analyze whether the contract has obvious security risks. Finally, from the privacy, mechanism design and security, performance and formal verification of the smart contract itself, and the existence of the three major platform applications Analyze and forecast the future research direction of blockchain smart contracts.
