Abstract

The invention discloses a block chain consensus mechanism based on an optimization problem, and relates to the technical field of block chains. The block chain consensus mechanism comprises the following steps: a generalized non-convex nonlinear integer programming optimization problem is constructed into a triple function, and the function has a solution space; when the sum of the lengths of allcomponents in the solution space exceeds a preset parameter, the components are cut, and functions and rewards are submitted and recorded to a block chain in multiple times; the function enters the waiting stage of the optimized life cycle and then enters the solving stage as a consensus problem of the block chain, to call whole network nodes to solve, and generate a new block; and the block chainmoves out the function in the settlement stage and issues a reward to the function effective solution submitter. According to the block chain consensus mechanism, the whole network computing power resource is effectively utilized while the data security of the block chain is ensured; the defect of resource waste caused by the fact that a large amount of computing power is used for hash operationwithout practical significance based on the block chain of an existing consensus mechanism is overcome; and the problem solving process provides rewards for the block chain, and the optimization rewards contribute to maintaining the stable development of the block chain.

Description

technical field [0001] The present invention relates to the technical field of block chain, and more specifically, relates to a block chain consensus mechanism based on an optimization problem. Background technique [0002] Blockchain technology realizes the transmission of credible information and the transfer of effective value on untrusted channels. In a decentralized scenario, the blockchain consensus mechanism solves the problem of data consistency and trust between nodes, which is a guarantee The key to the continuous operation of the blockchain system. However, the blockchain network with the existing consensus mechanism uses a large amount of computing power for meaningless hash operations, resulting in a huge waste of resources. Contents of the invention [0003] The present invention provides a block chain consensus mechanism based on an optimization problem, and the present invention aims to solve the above technical problems at least to a certain extent.
