Embodiment

[0075] The following is a more detailed description of the specific implementation process of the present invention in combination with the blockchain-based personnel assessment system.

[0076] (1) Select the leader node: In the blockchain-based personnel assessment system, the administrator is the consensus node, and the generation of a new block needs to select the leader node that packs the data to generate the block among the consensus nodes, and the new block is validated by the consensus node are recorded in the blockchain ledger. exist In a system composed of consensus nodes, the leader node is selected according to formula (1), and zero or more leader nodes can be generated.

[0077] (2) The leader node generates blocks: In each round of new block generation, due to the uncertainty of the number of leader nodes, multiple blocks may be generated or no blocks may be generated, and the next round of consensus will be carried out without a leader node , and the leader ...

Abstract

The invention discloses a consensus method applied to a personnel assessment system based on a block chain, and belongs to the technical field of the Internet. According to the method, the system datais checked by the computing power while the consensus node performs block verification by using the computing power, so that the accuracy of the data is maintained, the behavior of tampering the datais avoided, and the computing power resource is effectively utilized; a plurality of leader nodes are selected for each round of consensus to generate new blocks, the blocks are stored in a directedacyclic graph mode, a main chain strategy is set to converge the blocks and reduce bifurcations, the block generation capacity of the block chain system is greatly improved, and the data processing capacity of the system is greatly enhanced; according to the method, for the calculation mode of the leader node, the node has an opportunity to become the leader node only when being superior to the average level, the probability of successful node competition is completely randomized by utilizing a cryptographic algorithm, competition cannot be participated through a strategy, and the honesty of the leader node and the randomness of election are ensured.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a consensus method applied to a blockchain-based personnel assessment system. Background technique [0002] Blockchain technology is a distributed storage system that can achieve decentralization, and can realize data transparency and immutability. Consensus algorithm is a method to achieve consensus among nodes in a distributed system. In the blockchain system, the distributed nodes reach agreement on the storage data through the consensus algorithm to jointly maintain the blockchain ledger. [0003] The current assessment of personnel based on blockchain technology is mainly to express the behavior of supervised personnel in the form of digital points, and use data to evaluate personal codes of conduct. This measure digitizes behavior and facilitates the assessment of personnel in a fair and just way and management, and easy to store and query. [0004] For e...
