Problems solved by technology

[0003] Traditional consensus algorithms such as PBFT have low performance in terms of Byzantine fault tolerance. In the existing blockchain system, the commonly used method for generating node bookkeeping rights is the blockchain consensus algorithm based on computing power (PoW), although It better solves the Byzantine fault tolerance problem, but still has the disadvantages of consuming a lot of computing resources, low transaction throughput, and being vulnerable to consensus attacks, such as double attacks, lightning attacks, and private mining.

Abstract

The invention provides a blockchain consensus mechanism implementation method and device, equipment and a storage medium, and the method comprises the following steps: carrying out the reliability evaluation of a basic node on a block chain, and obtaining a reliability value of the basic node; selecting a first preset number of basic nodes from the basic nodes according to the reliability values to form a consensus group; when a transaction bookkeeping request message is received, controlling the base nodes to carry out mining, and after a certain base node succeeds in mining, enabling the base node which succeeds in mining to select one base node from the consensus group to serve as a leader node; and controlling the leader node to publish the blockchain block. The method can achieve the purposes of saving computing resources, improving the transaction throughput and improving the anti-attack performance of the nodes.

Description

technical field [0001] The present invention relates to the technical field of consensus mechanism / proof of work (PoW), in particular to a block chain consensus mechanism implementation method, device, equipment and storage medium. Background technique [0002] Blockchain is a decentralized system structure. The core of blockchain technology is a consensus mechanism for reaching consensus on the legitimacy of transactions among individuals who have no basis for mutual trust without central control. [0003] Traditional consensus algorithms such as PBFT have low performance in terms of Byzantine fault tolerance. In the existing blockchain system, the commonly used method for generating node bookkeeping rights is the blockchain consensus algorithm based on computing power (PoW), although It solves the Byzantine fault tolerance problem better, but still has the disadvantages of consuming a lot of computing resources, low transaction throughput, and being vulnerable to consensus...
