Block chain consensus method based on random number mapping

Abstract

The invention requests to protect a block chain consensus method based on random number mapping, which is used for efficiently and fairly selecting accounting nodes, and an algorithm comprises three steps of selection of supervision nodes, generation and calculation of uniformly distributed random numbers, and selection of the accounting nodes. The supervision nodes are responsible for calculatingthe random number generated by each node participating in accounting on the chain, then selecting the accounting nodes, then sending a broadcast to other nodes, and publishing which node is the nextaccounting node; a calculation result of the uniformly distributed random numbers corresponds to the id of the node participating in accounting, namely the id of the next accounting node; the accounting node is responsible for recording and maintaining data on the chain; on the basis of random number mapping, a selection mode of a bookkeeper in a traditional consensus algorithm is improved, a consensus mechanism based on random number mapping is provided, bookkeeping nodes can be selected more efficiently and fairly, the social stratification phenomenon in an existing block chain is improved,consensus efficiency is greatly improved, and the centralization trend is resisted.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a block chain consensus method based on random number mapping. Background technique [0002] How to efficiently reach a consensus in a distributed system is an important research issue in the field of blockchain and even distributed computing. Similar to the opposition between "democracy" and "centralization" in social systems, the efficiency of reaching consensus in a system with more decentralized decision-making power The lower the value, the higher the stability and satisfaction of the system; while the system with more centralized decision-making power is more likely to reach a consensus, but at the same time it is more likely to appear autocratic and dictatorial. One of the core advantages of blockchain technology is that in a decentralized system with highly decentralized decision-making power, each node can efficiently reach a consensus on the validity and consistency...

Not only that, but this may also exacerbate the phenomenon of "the rich get richer and the poor get poorer" in the blockchain, which is not conducive to the healthy and sustainable development of the blockchain

[0006] Although the consensus mechanism is constantly evolving, the time to reach consensus is constantly shortening, and it can also achieve certain scalability, but the current consensus mechanism cannot support millisecond-level data on-chain, and cannot distribute accounting rights fairly and reasonably. In PoW In PoS, the node with the Hash value that meets the conditions is calculated to obtain all benefits; in PoS, the older the coin age, the greater the probability of obtaining the right to dig blocks and obtain all benefits; for PoW, if a node masters more than all With 50% of the computing power of the network, it is possible to manipulate the entire blockchain to obtain all benefits; for PoS, if a node has more than 50% of the currency age of the entire network, it is possible to share all the benefits
