A Flexible Electronic Data Exchange Framework Based on Consortium Blockchain

Abstract

With the rise of Internet-based services and platforms to address and support system scalability, data security, service trustability and user privacy protection, it is hard for traditional electronic data exchange systems based on centralized architecture and private network to serve enterprises and organizations well. In this study, an electronic data exchange framework based on consortium blockchain is proposed to support Internet-based flexible decentralized electronic data exchange service. By adopting blockchain and decentralized public key infrastructure technologies, the proposed framework natually achieves system scalability, service trustability, data security and user privacy protection. A system prototype is constructed to evaluate the performance of the proposed framework. The experimental results show that the prototype can generate 60 data exchange contracts per second; it is around 5 million data exchange volume in 24 hours.
