With the rapid development and application of information technology, blockchain technology (BT) has become an important means to promote the integration of the real economy and the digital economy. BT reached a certain level of development for application in asset transactions, finance, and traceability. However, existing technology provides no reasonable trading method and application framework for the use of BT in peer-to-peer (P2P) transactions. This article proposed a blockchain-based P2P transaction method, which we simulated using Go programming language. We apply BT to smart contracts and electronic transactions, and introduce a mechanism of association between digital assets and physical assets. The proposed method can ensure the data security and establish trust among entities. It can also reduce business divergence and costs. For the sensitive data involved in a transaction, we propose an encoding algorithm to prevent the leaks of sensitive data in circulation. The calculations of the matrices of the algorithm can use the computing resources of all nodes in the blockchain to calculate in parallel, and then summarize the results. This makes full use of the massive graphic processing unit resources in the blockchain, and makes the calculation valuable.

基于区块链的电子商务交易P2P交易方法及敏感数据编码


随着信息技术的快速发展和应用，区块链技术（BT）已成为推动实体经济与数字经济融合的重要手段。 BT在资产交易、金融、溯源等方面的应用达到了一定的发展水平。然而，现有技术并没有为BT在点对点（P2P）交易中的使用提供合理的交易方法和应用框架。本文提出了一种基于区块链的P2P交易方法，我们使用Go编程语言对其进行了模拟。我们将BT应用到智能合约和电子交易中，引入数字资产和实物资产的关联机制。所提出的方法可以确保数据安全并建立实体之间的信任。它还可以减少业务分歧和成本。对于交易中涉及的敏感数据，我们提出了一种编码算法来防止流通中敏感数据的泄露。该算法矩阵的计算可以利用区块链中所有节点的计算资源并行计算，然后汇总结果。这充分利用了区块链中海量的图形处理单元资源，让计算变得有价值。
