Copyright Certificate Storage and Trading System Based on Blockchain

In the era of digitalization and networking, the high cost and long time of traditional centralized copyright protection methods make the copyright of digital works cannot be well protected and the infringement phenomenon be serious. Blockchain, as a decentralized distributed database, can store the copyright information of works. This paper researches and analyzes the advantages of blockchain in copyright protection and the current research status, and finally a copyright certificate storage and trading system based on blockchain is designed. In this system, registration confirmation, transaction certificate, and dispute protection are researched as a complete process. And the certificate storage data on the blockchain are precisely designed, which greatly reduces the time and cost of rights protection. What's more, the copyright of digital works is divided by studying laws related to copyright in China, which makes this system more suitable for practical applications.
