摘要
区块链为构建社会价值传递和信任机制提供了一种新的技术。区块链的快速发展促进了智能合约与人工智能、大数据、物联网等技术的深入融合,其安全性受到重点关注。近几年,区块链与智能合约安全研究取得了较大进展,基于区块链智能合约,对智能合约的运行机制、链上安全和链外安全的最新相关研究成果进行归类、分析、比较、总结和讨论,并展望了智能合约安全性的研究方向和趋势。
Blockchain provides a new technology for building transmission and trust mechanism of social ralue.The rapid development of blockchain has promoted the deep integration of smart contract with artificial Intelligence,big data and internet of things,so its security has attracted attention.In recent years,researches on security of blockchain and smart contract have made great progress.Thus,based on smart contract on the blockchain,the related works on security of operating mechanism,on-chain smart contract security and off-chain security were classified,analyzed,compared,summarized and discussed.The hot issues of smart contract security in the future were forecasted.
