【Abstract】The conventional centralized data trading system confront the problem that the Trusted Third Party (TTP) may be dishonest, which harms the fairness and transparency of the system. Besides, we notice that most data trading systems lack distinguishing between the copyright and the use-right in trading. To address these issues, we propose a novel blockchainbased data trading system with copyright-preserving, called CDTP, mainly including two blockchains and an agreement. The copyright chain, one of the blockchains, is designed for registering and trading copyrights stored in the form of atomic transactions. It adopts an auction-based Byzantine agreement, namely ABFT. Another is use-right blockchain, which records use-right transactions and stores data, combined with IPFS-based storage. Moreover, we carry out experiments to simulate the performance of ABFT when it is under attacks.
