摘　　要：当今网络交易日趋频繁,各种网络交易系统层出不穷,使得网络交易安全面临众多挑战,并成为信息安全领域的研究热点,确保网络交易安全具有重要意义。鉴于交易安全需要,区块链技术正逐渐被金融、市场、经济等领域交易环节研究和采纳,文章针对区块链技术的基本知识、交易架构、工作模式、区块链投资交易过程进行分析和研究,构造了一个基于以太坊区块链技术的投资交易平台,采用智能合约的方式进行投资交易活动。文章详细论述了系统的开发和实现过程,展示了交易全过程,讨论并分析了交易过程的安全问题以及智能合约本身的安全问题。最后通过实验验证了该投资交易系统的可用性。Nowadays, with the increasing frequency of network transactions and the emergence of various network transaction systems, the security of network transactions is facing many challenges, and it has become a research hotspot in the field of information security. It is of great significance to ensure the security of network transactions. In view of the need for transaction security, blockchain technology is gradually being studied and adopted in the fields of finance, market and economy. In this paper, the basic knowledge of blockchain technology, transaction structure, working mode and the process of blockchain investment and transaction are analyzed and studied, and an investment and transaction platform based on Ethereum blockchain technology is constructed. Smart contract is adopted on this platform. In this paper, the development and implementation process of the system are discussed in detail, the whole transaction process is displayed, the security problems of the transaction process and the security problems of the samrt contract itself are discussed and analyzed, and the availability of the investment trading system is verified by experiments.
