Embodiment 1

[0068] Such as figure 1 As shown, an asynchronous BFT&DPOS consensus mechanism that distributes validator rewards based on a verifiable random function includes the following steps:

[0069] S1: System initialization. In the VBDPOS consensus mechanism, the applicant who wants to become a node candidate submits equipment, facilities, personnel information and proof, and the candidate becomes a node after passing the application;

[0070] S2: Select super nodes. Token holders vote for each node candidate through the voting system. According to the ranking of votes, the 21 nodes with the highest number of votes are selected as super nodes. Every 252 blocks are produced as a block cycle. At the beginning of each block cycle, the number of votes will be updated in real time, and the ranking of super nodes and verifiers will be updated;

[0071] S3: Select a validator. When the standby node meets the following three conditions, it can apply to become a validator and participate in ...

Abstract

The invention discloses an asynchronous BFT & DPOS consensus mechanism for distributing verifier rewards based on a verifiable random function. The asynchronous BFT & DPOS consensus mechanism mainly comprises the steps that S1, initializing a system; S2, selecting a super node; S3, selecting a verifier; S4, generating a block; S5, confirming the blocks; S6, distribution of rewards; and S7, switching the super nodes. According to the invention, the role of a verifier is introduced; the verifier enables the standby node not to be idle any more; according to the VBDPOS consensus mechanism-based system, the super node does not participate in the verification work of the block but participates in the verification work of the block, and the verifier can enable the system to stop running by executing the verification right at the first moment when the super node is serially connected with the hostile attack system, so that the system based on the VBDPOS consensus mechanism can prevent the attacker from attacking the system at the first time, and system safety is improved. Through the design of the block confirmation scheme, the VBDPOS consensus mechanism enables the performance not to bereduced too much on the basis of improving the overall safety, and can meet the existing commercial requirements.

Description

technical field [0001] The present invention relates to the technical field of block chain, and more specifically, relates to an asynchronous BFT&DPOS consensus mechanism that distributes verifier rewards based on a verifiable random function. Background technique [0002] The emergence of blockchain technology is called a new generation of revolution. The emergence of blockchain technology allows distributed systems and distributed applications to flourish. The most important thing in the blockchain technology of chain distributed system is the consensus mechanism. The consensus mechanism is the core technology for the security and good development of the blockchain distributed system. [0003] The blockchain system is decentralized, and the nodes are scattered and parallel everywhere, so a system must be designed to maintain the order and fairness of the distributed system's operations, unify the version of the blockchain, and reward the provision of resource maintenance ...
