This study proposes a blockchain-based copyright depository scheme. Blockchain is used as an underlying architecture to develop the digital copyright depository system. The system is built to solve the existing problems of the copyright depository, such as ambiguous ownership, low cost of piracy, rampant piracy, and difficulty in copyright monitoring, protection and sharing. Digital verification technology, supervision nodes, Oracle service and smart contract are introduced to provide certification depository, flow tracking, rights protection and sharing services for digital content. A system performance test is carried out for the registration service and query service, and the results show that the throughput of the two services was 195 and 366 times/second respectively with zero failure rate. The blockchain-based copyright depository system has been developed into a software as a service (SaaS) platform-blockchain copyright depository platform and provides services for dozens of institutions and enterprises, such as Zhijiang Notary Office, Xinhua Zhiyun, Himalaya, etc.
