Digital Copyright Transaction Scheme Based on Blockchain Technology

In the current digital and networked era, the demand for digital copyright transactions is growing, and the traditional centralized registration method has problems such as high costs and long time limits for copyright registration, and difficulties in copyright protection. The technical features of blockchain technology, such as decentralization, immutability of information, openness and anonymity, offer new opportunities for digital copyright protection. We design a digital copyright transaction scheme based on blockchain technology. Firstly, we use Java to build an underlying platform that simulates the operation of the blockchain data layer, consensus layer and contract layer, on top of which we design a distributed underlying blockchain platform that can securely generate blocks, generate transactions, validate transactions, add transactions into blocks, broadcast blocks, validate blocks and add blocks into the blockchain, and use an interface tomanipulate the database for the trading functions to be implemented by the platform, and a visual interface is provided to facilitate users' transactions of digital copyright content. The results showthat our platform can effectively address trust, intermediary and execution problems in digital copyright transactions and help reduce copyright infringement.
