Abstract

The invention provides a consensus resource slicing method based on a block chain, and relates to the technical field of block chains. The improved block chain consensus resource slicing method is based on a traditional practical Byzantine fault-tolerant algorithm (PBFT) consensus mechanism, and specifically comprises the steps of performing slicing management on consensus resources in a block chain system, dividing consensus nodes into a plurality of different consensus sets, and concurrently performing consensus on the plurality of consensus sets. Meanwhile, in order to ensure the stabilityof the consensus process, a main node with a high stability value is dynamically selected through the stability value, the main node generates a plurality of preparation blocks from the collected dataneeding consensus, each consensus set performs consensus on the corresponding preparation block, and finally, the main node generates a formal block from the data passing the consensus. Compared withthe prior art, the phenomena of low throughput in the consensus process and resource waste in the consensus process are mainly solved, the throughput of the blockchain system can be improved, and theconsensus resource waste is reduced.

Description

technical field

[0001] The invention relates to a block chain-based consensus resource slicing method, which belongs to the technical field of block chains. Background technique

[0002] Now the commonly used consensus mechanism of the alliance chain is PBFT, which is the Practical Byzantine Fault Tolerant Algorithm. PBFT is a state machine copy replication algorithm, that is, the service is modeled as a state machine, and the state machine performs copy replication on different nodes of the distributed system. In the common PBFT algorithm, all nodes participate in the consensus process, resulting in high consumption of communication resources and strong destructiveness of malicious nodes. In the patent "A Consensus Method Based on PBFT Improvement", nodes with high stability values ​​are selected to participate in the consensus, and the stability values ​​are dynamically adjusted. Although the communication consumption in the formula process is reduced, the consensus speed...
