Embodiment Construction

[0031] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0032] like figure 1 As shown, a blockchain DPoS consensus method based on a trust mechanism disclosed in the embodiment of the present invention, when the method is implemented, first defines the trust degree and trust energy level for the nodes in the blockchain system, and then through the trust right mechanism Proxy nodes are elected, and then a verifiable random function is used to select accounting nodes among the proxy nodes. Finally, in the operation of the blockchain network, trust reward...

Abstract

The invention discloses a blockchain DPoS consensus method based on a trust mechanism. The method first introduces the concepts of trust degree and trust energy level for nodes in the blockchain system. Nodes with a trust energy level of Error cannot participate in the election of proxy nodes. , and then select the proxy node through the trust rights mechanism; then use the verifiable random function to select the accounting node from the proxy node; finally, during the operation of the blockchain network, trust rewards and punishments for the node behavior, and reduce the error to the error Level accounting nodes adopt an interrupt elimination strategy. The present invention reduces the probability of malicious nodes becoming bookkeeping nodes by tracking the trust level of nodes and trust rewards and punishments of nodes, increases the participation enthusiasm of ordinary nodes, ensures the reliability of the entire consensus method, and uses the degree of trust as proof of equity, No additional token distribution is required.

Description

technical field [0001] The invention relates to a blockchain DPoS consensus method based on a trust mechanism. The method introduces the concepts of node trust degree and trust energy level, uses the trust mechanism to reduce the influence of malicious nodes on the system in the selection of proxy nodes and the work of bookkeeping nodes, and can Improving the enthusiasm of nodes to participate belongs to the field of blockchain technology. Background technique [0002] Blockchain can be regarded as a distributed ledger (distributed database), relying on "crowd intelligence" (distributed consensus mechanism) to build a distributed system of trusted consensus, with records that cannot be tampered with and traceable. The blockchain is a milestone in the history of human credit evolution following blood relative credit, precious metal credit, and central bank banknote credit. The consensus mechanism is the core of the blockchain, which solves the problem of how to reach a conse...
