Research And Implementation Of Digital Right System Based On Blockchain

With the booming development of the Internet,the digital rights and its related content creation industries have entered a stage of rapid development,and the various forms of digitally-created content that depend on the Internet can be easily and quickly delivered and reached through various channels in the network.However,the current digital rights protection system still has problems in the rapid development of digitalization and networking,such as high cost and low efficiency of rights protection,which makes it possible for rights piracy infringement to take advantage of.Blockchain technology,relying on the digital cryptocurrency that has exploded in recent years,has come into the public vision with its unique underlying data governance technology.In this thesis of digital rights protection,it can provide a different kind of solution.This thesis combines the consensus algorithm of PoP(Proof of Performance)of the data nodes in the coalition chain with the provision of Web access function to fulfill the many missing functional requirements in the digital rights protection system,such as rights authentication,rights authorization,rights transaction,and rights infringement protection but also maintains a smaller increase in network processing consumption when the number of nodes in the consortium chain increases compared with the common consensus algorithm of the consortium chain.The network processing consumption increases less when the number of nodes in the federated chain increases compared to the common consortium chain consensus algorithm,thus ensuring the performance of the overall chain.The research innovation points and system work in this paper are summarized as follows.(1)The operation logic of the PoP consensus algorithm is designed.This algorithm is a grouping application based on the implicit grouping attribute of the consortium chain.The idea of dividing and conquering to reduce complexity is associated with the consortium chain architecture,and through the demonstration,it can effectively suppress the flooding problem caused by the consensus data broadcast transmission between each node in the blockchain.Implemented and tested the feasibility and performance of the PoP consensus algorithm.The framework based on Hyperledger Fabric implements the PoP algorithm and tests the PBFT consensus algorithm and RBFT consensus algorithm commonly used in the alliance chain.The experimental results show that the PoP algorithm can effectively improve the throughput performance of the overall link system compared with the PBFT and RBFT algorithms more than 35%.(2)Completed the development of the blockchain digital rights system.According to the analysis and design of the functional requirements of the digital rights protection system,combined with the realization of the PoP consensus algorithm,the development and testing of the system functions are completed.The test results show that the system is able to smoothly run each module component designed in the digital rights protection process,and that it show that the system could guarantee 95%requests done with 10 millisecond and 99%requests done with 15 millisecond,even the QPS ran to the 800 of non-logical sequential requests in the specified test environment.
