智能合约漏洞与安全审计手段浅析

Smart Contract Attacks and Protects

智能合约为区块链技术的核心,区块链的正常工作,依赖于缜密的智能合约。然而智能合约本身往往存在着漏洞,漏洞提供了攻击的可能性,将智能合约的攻击分为基本的四类,分析几种重要的攻击技术,揭示攻击防御、智能合约安全的重要性。同时分析了多种常用的智能合约检测工具,并指出各种工具的优劣。最后讨论了智能合约有关安全的建议和未来研究方向,希望能够将智能合约技术进一步融入到日常使用之中。

Smart contracts are at the core of blockchain technology,and the proper functioning of blockchain relies on meticulous smart contracts.However,smart contracts themselves often have vulnerabilities,and the vulnerabilities provide the possibility of attacks,this paper divides the attacks against smart contracts into four basic categories,analyzes several important attack techniques,and reveals the importance of attack defense and smart contract security.It also analyzes a variety of commonly used smart contract detection tools and points out the advantages and disadvantages of various tools.Finally,the recommendations and future research directions related to smart contract security are discussed in the hope that smart contract technology can be further integrated into daily use.
