A Byzantine Fault Tolerant Method and Its Governance System of Token Economy

Abstract

The invention discloses a Byzantine fault tolerance method and a token economy management system. The method comprises the steps of delegating right and interest of a node, which is to participate inblock chain operation, to a block chain network node, thereby obtaining a right and interest value; constructing a right and interest table with the length being coefficient multiple of the total nodequantity, wherein the occupied length of information of each node in the right and interest table is in direct proportion to the right and interest value of each node; generating a random number by using a random function, and selecting a numerical value in the right and interest table, thereby selecting multiple nodes to participate in the operation; allocating different working proposals and endorsements to the nodes participating in the operation, and performing confirmation to finish a consensus; and if alternative blocks obtain confirmation of a confirmation node, storing the blocks finishing the consensus by all consensus nodes. The system comprises a block chain network, a control unit, a detection unit, an operation unit and an allocation unit; and computing power of different nodes is detected, different work is allocated, and based on this, benefits are allocated. The right and interest ratio, the computing power and the input operation and maintenance cost are comprehensively considered, and the weights and the benefits are reasonably allocated.

Description

technical field [0001] The present invention relates to a consensus algorithm (consensus mechanism) of a blockchain (Blockchain) network, in particular to a Byzantine Fault Tolerance (BFT) method and a token economy governance system. Background technique [0002] At present, blockchain technology has been widely used, and its decentralized model ensures that data is not easy to be tampered with, thus improving security. [0003] In practical applications, a blockchain network containing multiple nodes (a node can be considered as a device participating in processing business in the blockchain) can provide corresponding business services for clients. Specifically, each node in the blockchain network will process the business request of the client and feed back the processing result to the client. During this process, the processing results generated by each node running independently may be inconsistent. In order to ensure The client can receive the correct processing resul...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is: more than 1 / 3 of the nodes of the traditional Byzantine algorithm cannot work after they stop working, and the proportion of the certificate owner nodes in the existing blockchain network, the weight and distribution of the operating nodes and ordinary nodes Unreasonable profit leads to frustration of node participation enthusiasm, lower investment and even withdrawal from the network, resulting in the degradation of the blockchain network
