BLOCKCHAIN CONSENSUS METHOD BASED ON TRUST RELATIONSHIP

WIPO Patent Application WO/2019/222993

A1

The present invention is applicable to the field of improvements in Internet technology, and provides a blockchain consensus method based on a trust relationship, the method comprising: S1. quantifying a trust relationship between nodes according to trading and block data; S2. constructing a trust relationship graph and generating a trust matrix according to the trust relationship between the nodes; S3. iteratively calculating a trust value of each node using the trust relationship between the nodes of a whole network; and S4. for each round of consensus, randomly selecting a representative node as a primary node having the bookkeeping rights, and the primary node selecting several trading creation blocks from a trading pit. A representative mechanism is used to professionalize a bookkeeping node, thereby reducing the consensus cost, reducing energy consumption, and improving the efficiency of node consensus and an expansion capability of an algorithm at the same time. A representative node is selected based on a trust relationship, without depending on a token of a blockchain, thereby preventing the bookkeeping rights from being concentrated to a few "rich people".
