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] Such as 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 rights 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 re...

Abstract

The invention discloses a block chain DPoS (Delegate Proof of Stake) consensus method based on a trust mechanism. According to the method, concepts of trust degree and trust energy levels are importedfor nodes in a block chain system; the nodes with a trust energy level of error cannot participate in proxy node competitive election; proxy nodes are elected through utilization of a trust authoritymechanism; accounting nodes are extracted from the proxy nodes through adoption of a verifiable random function; and in a block chain network operation process, trust reward and penality are carriedout on node behaviors, and interruption and kickout policies employed for the accounting nodes of which trust energy level is reduced to the error energy level. According to the method, through tracking of the trust energy levels of the nodes and through trust reward and penality of the nodes, a probability that malicious nodes become the accounting nodes is reduced; participation active degree ofcommon nodes is improved; reliability of the whole consensus method is ensured; the trust degree is taken as a delegate proof of stake, so additional token money distribution is avoided.

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...
