Abstract： The application of blockchain technology makes the determination of the ownership of digital copyright and the transformation of digital copyright into digital assets and digital asset finance and transactions fairer and more just.Right holders only need to submit their works to the blockchain digital copyright system through the network,and the entire process is automatically completed. It has the following advantages: No geographical restriction; The whole process is automatically completed by the system; The ownership application is completed in real time; The original work or digital original is encrypted to ensure security. The digital copyright system of blockchain technology includes: the underlying infrastructure system of the blockchain; digital copyright legal process application system; digital copyright application process application system; digital copyright fingerprint encryption application system; digital copyright authentication application system; digital copyright rights confirmation application system; distributed data storage control application system; point-to-point control protocol. Blockchain digital copyright asset transaction application system includes: blockchain underlying infrastructure system; digital asset transaction application system; copyright asset value assessment and valuation alliance application system; legal lawyer affairs agency alliance application system; judicial institution joint application system. The blockchain digital copyright asset financial service system includes: financial asset financing institution application system; medium and short-term credit application system.
