Research on digital copyright blockchain technology

As a decentralized network structure based on P2P network and with cryptography as its core, blockchain technology establishes trust relationship on the network by pure mathematical method without relying on intermediate platform. There are three problems in traditional digital copyright industry: difficult to confirm the rights, difficult to authorize rights and difficult to maintain rights. This paper makes a deep research on the blockchain technology of digital copyright. With the help of self-supervision, traceability and decentralization of blockchain technology, as well as the Map function, we can improve the data transmission rate in the multi-channel model and obtain accurate time complexity values. Hence the probability of all kinds of digital copyright infringement events is greatly reduced.
