摘 要

随着科技的不断发展，区块链成为继云计算之后的又一热议话题，以区块链作为底层技术的应用不断涌出，学术界围绕区块链技术去中心化、安全可信等特点，对其应用场景也展开了广泛的探讨。现阶段，社会化电子商务系统的数据呈现出数据类型多、数据体量大和数据存储中心化等特征，过于中心化的数据处理方式容易出现效率低、成本高和安全性差等问题。为此，本文利用区块链技术对社会化电子商务系统“小红书”进行去中心化的设计。

本文首先阐述了研究的背景和意义，对国内外在区块链、社会化电子商务领域的研究进行了综述。其次，对区块链和社会化电子商务的相关技术与概念进行介绍与说明。然后，从产品结构与功能流程等方面分析“小红书”的现状，并据此对基于区块链的“小红书”的系统需求进行分析。最后，从系统架构和功能模块方面进行系统设计，基于区块链的“小红书”社会化电子商务系统主要包括登陆与注册、商品管理、主页管理、互动管理、购买、搜索、数据授权管理和区块链维护模块，各功能模块均有较详细的文字说明和直观图示。

关键词：区块链，社会化电子商务，系统分析与设计

Abstract

With the continuous development of science and technology, blockchain has become another hot topic after cloud computing, and the application of blockchain as the underlying technology has continued to emerge. The academia has extensively discussed the application scenarios of blockchain based on its characteristics of decentralization, security, and credibility. At the present stage, the data of social e-commerce systems presents features such as multiple data types, large data volume, and centralization of data storage. Over-centralized data processing methods are prone to problems such as low efficiency, high costs, and poor security. For this reason, the paper implements blockchain technology for the design of “Xiaohongshu”, a decentralized social e-commerce systems.

This paper first elaborated the background and significance of the research, and reviewed the domestic and international research in the field of blockchain and social e-commerce. Secondly, the relevant technologies and concepts of blockchain and social e-commerce were introduced in detail. Then, from the aspects of product structure, function flow and other aspects, the status quo of "Xiaohongshu" was analyzed. Based on this, the system requirements of "Xiaohongshu" were analyzed. Finally, the system was designed from the aspects of system architecture and functional modules. The blockchain-based social e-commerce system with “Xiaohongshu” as an example mainly includes modules of login amp; registration, merchandise management, homepage management, interactive management, purchase, search, data authorization management, and blockchain maintenance. The functional modules are equipped with detailed text descriptions and intuitive graphs.
