Construction of credibility evaluation system for blockchain-supported big data trading platforms
区块链支持的大数据交易平台可信度评估体系构建

摘要

区块链技术的快速发展使其在大数据交易平台中的应用越来越广泛，而平台的可信度直接影响数据交易的安全性与有效性。本文提出了一种基于区块链技术的大数据交易平台可信度评估体系，旨在通过区块链的去中心化、不可篡改等特性，提高平台的透明度和信任度。该评估体系包括平台的数据完整性、交易透明性、参与方信誉度等多个维度，结合智能合约技术实现自动化、实时的评估。本文重点探讨了如何在区块链环境下构建可信度评估模型，评估维度的选择及其相互关系，进而提升大数据交易平台的信任管理水平，为大数据产业发展提供保障。

Abstract

The rapid development of blockchain technology has led to its increasingly widespread application in big data trading platforms, where the credibility of the platform directly affects the security and effectiveness of data transactions. Therefore, this paper proposes a blockchain-based credibility evaluation system for big data trading platforms, aiming to enhance the transparency and trustworthiness of the platform through blockchain’s characteristics such as decentralization and immutability. The evaluation system covers multiple dimensions including data integrity of the platform, transaction transparency, and participant reputation, and integrates smart contract technology to achieve automated and real-time evaluation. This paper focuses on exploring how to construct a credibility evaluation model in a blockchain environment, the selection of evaluation dimensions and their interrelationships, thereby improving the trust management level of big data trading platforms and providing guarantees for the development of the big data industry.
