摘　　要：针对以太坊Solidity语言智能合约设计问题,在研究开源合约程序的基础之上识别了面向智能合约的六种设计模式,包括访问约束、状态机、前置条件、后置条件、紧急制动和代理。面向智能合约的设计模式有益于提升合约代码可读性,降低合约语言学习难度,也是提高区块链合约代码审计效率的途径。Focused on the smart contract design in Solidity language on Ethereum,this paper identifies six design patterns for smart contract based on the study of open source code of contracts,including Access Restriction,State Machine,PreCondition,PostCondition,Emergency Stop,and Proxy.The design patterns identified can be utilized to improve the readability of contract code,reduce the difficulty of contract language learning.Moreover,it is also an approach to improve the efficiency of blockchain contract code audit.
