Security Mechanism Analysis of Blockchain Smart Contract in Cross-border Trade Field
跨境贸易领域中区块链智能合约安全机制分析

摘要

当前所说的智能合约，就是能够自动执行已经预制好的规则、条约，且基于计算机而存在的交易程序，最近几年，伴随区块链技术的创新与发展，其不仅备受关注更在各个行业领域当中被广泛应用。因为智能合约属于是网络环境之下，独立地进行自我验证与自动执行，所以其中存在诸多安全问题。文中对区块链中智能合约存在的安全隐患进行分析，基于实际业务的开展场景，提出全面、有效的安全机制，希望能够为跨境贸易中区块链智能合约的安全应用提供一些帮助。

Abstract

The current smart contract is a transaction program that can automatically execute prefabricated rules and treaties. In recent years, with the innovation and development of blockchain technology, it has not only attracted much attention but also been widely used in various industries. Because smart contracts are independently self-validated and automatically executed in a network environment, there are many security problems. This article analyzes the potential security risks of smart contracts in blockchain, and proposes a comprehensive and effective security mechanism based on actual business development scenarios, hoping to provide some help for the secure application of smart contracts in blockchain in cross-border trade.
