Abstract

The invention provides a consensus method, device and system based on effective computational force contribution. The method includes the steps of receiving computational tasks issued by a computational publisher and computational requirements corresponding to the computational tasks; configuring computing tasks according to computing requirements; obtaining the data needed by the computing task and compiling the computing task into a Boolean circuit; forming a plurality of parallel computing tasks, and distributing the parallel computing tasks to a plurality of computing nodes for computing;receiving the calculation result and the calculation proof of the parallel calculation task by the calculation node, and determining whether the calculation result is valid or not according to the calculation proof; if it is valid, determining the cumulative calculation contribution value of the calculation node corresponding to the calculation result, and allocating the preset reward for each calculation node; receiving voting data of each computing node as cumulative calculated contribution value, and voting on the candidate nodes; obtaining the N consensus nodes, wherein the practical Byzantine fault-tolerant algorithm is used to complete the consensus of the block data among the N consensus nodes.

Description

Technical field [0001] The present invention relates to the field of blockchain technology, and in particular to a consensus method, device and system based on effective computing power contribution. Background technique [0002] At present, blockchain technology is developing rapidly. For example, some current digital currencies (Bitcoin, Ethereum, etc.) all use blockchain technology. In blockchain technology, a consensus mechanism needs to be adopted, that is, through the voting of special nodes, the verification and confirmation of the transaction can be completed in a short time; for a transaction, if several nodes with irrelevant interests can reach a consensus , It can be considered that the whole network can reach a consensus on this. [0003] At present, the blockchain, especially the mainstream of the public chain, still uses consensus such as Proof of Work (PoW), Proof of Stake (PoS) or Delegated Proof of Stake (DPoS). Mechanism or its variants, and consensus mechanisms...
