Copyright video network-wide viewing recording system based on CBC-PBFT consensus mechanism

The invention relates to a copyright video network-wide viewing recording system based on a CBC-PBFT consensus mechanism, comprising a plurality of clients, a plurality of video network-wide viewing record generating devices, and a plurality of information processing nodes, a plurality of confirming nodes, a plurality of peer nodes and certificate nodes that constitute a blockchain. The PBFT consensus mechanism is improve to obtain a system more suitable for recording video playback data, different information processing nodes are communicated with each other and performed with consensus to obtain consensus video playback information, the consensus playback information is secondarily confirmed by the confirming nodes to finally reach the consensus to ensure the reliability and reliabilityof the data. The fault tolerance of each node is high, and the number of communication times in the data recording process is small. The identity and function of each node are determined, and the copyright video network-wide
