Abstract
Background: With the development of network technology and the continuous increase in user-generated content on the Internet, the protection of digital copyright is particularly important.
Objective: In order to better protect the copyright of digital works, this paper proposes a Polkadot scheme based on the advantages of blockchain cross-chain technology.
Methods: The scheme sets up three parallel chains, including digital work chain, copyright management chain, and dispute arbitration chain, and shows the information interaction process of Validators, Fishermen, Collators, and Nominators.
Results: The research shows that the scheme has more advantages than a single chain or alliance chain. It has a shorter block creation time, better security, and availability.
Conclusion: The findings provide new ideas for copyright registration, copyright trading, and infringement maintenance of digital works and also broadens the application of cross-chain technology of blockchain.
Keywords: Polkadot, copyright protection, parachain, digital works, blockchain, relay chain.
