In contemporary data-driven economies, data has become a valuable digital asset that is eligible for trading and monetization. Peer-to-peer (P2P) marketplaces play a crucial role in establishing direct connections between data providers and consumers. However, traditional data marketplaces exhibit inadequacies. Functioning as centralized platforms, they suffer from issues such as insufficient trust, transparency, fairness, accountability, and security. Moreover, users lack consent and ownership control over their data. To address these issues, we propose an innovative blockchain-powered, decentralized P2P data exchange model for self-sovereign data marketplaces. This user-centric decentralized approach leverages blockchain-based smart contracts to enable fair, transparent, reliable, and secure data trading marketplaces, empowering users to retain full sovereignty and control over their data. In this article, we describe the design and implementation of our approach, which was developed to demonstrate its feasibility. We evaluated the model's acceptability and reliability through experimental testing and validation. Furthermore, we assessed the security and performance in terms of smart contract deployment and transaction execution costs, as well as the blockchain and storage network performance.
在当代数据驱动的经济中，数据已成为一种有价值的数字资产，具备交易和货币化的资格。点对点（P2P）市场在数据提供者和消费者之间建立直接联系方面发挥着关键作用。然而，传统数据市场存在不足之处。作为集中式平台，它们存在信任不足、透明度不够、公平性欠缺、问责机制不完善以及安全性差等问题。此外，用户对自己的数据缺乏同意权和所有权控制权。为解决这些问题，我们为自主主权数据市场提出了一种创新的、由区块链驱动的去中心化P2P数据交换模型。这种以用户为中心的去中心化方法利用基于区块链的智能合约来实现公平、透明、可靠且安全的数据交易市场，赋予用户对其数据保留完全主权和控制权。在本文中，我们描述了我们方法的设计与实现，该方法旨在证明其可行性。我们通过实验测试和验证评估了该模型的可接受性和可靠性。此外，我们从智能合约部署和交易执行成本以及区块链和存储网络性能方面评估了安全性和性能。
