Abstract:

In the current era of digitalization and networking,the demand for digital copyright transactions is increasing.The traditional centralized copyright protection system has series of problems such as high registration costs,long work acceptance times,and being vulnerable to tampering by saboteurs.Blockchain as a decentralized network structure and based on P2P network and cryptographic technology,which can establish trust relationship on the network by pure mathematics.Without relying on the middle platform,blockchain technology can naturally alleviate the above problems.With the help of self-regulatory,traceable and decentralized features of blockchain technology and digital copyright trading scenarios,a digital copyright trading system model was designed.The new system is based on the advanced permissioned blockchain provided by IBM.The implementation of copyright registration and copyright transaction can ensure the integrity and tamper-resistant of the information.Finally,the installation time of chain code deployment was tested.The results show that the system is simple to install and has low maintenance costs.Compared with the traditional trusted third party copyright authentication mechanism,the blockchain-based digital rights trading system has a short registration time,no registration fee,and better architecture security and scalability.

Key words: digital rights trading, blockchain, superbooks, system design and implementation
