The current copyright protection and copyright transactions have problems such as high platform fees, opaque transaction information, difficulty in copyright protection, and slow speed. The current interplanetary file system has gaps in file-sharing; Most blockchain frameworks do not use national secret algorithms, which causes security uncertainty. This system uses smart contract accounts to define copyrights, uses multi-person accounts to define cooperation, treats copyright deposits from the perspective of transactions, and uses many fully automatic key "center" to be responsible for the key distribution of encrypted files, which can reduce the single point pressure of the copyright center server, reduce the negative impact of single-point invalidation of the copyright center on transactions and reduce the review time. We also achieved decentralized copyright transactions and secret key transmission. By using national secret algorithms for encryption, signature, and hashing, we can get rid of excessive dependence on foreign algorithms.
