System and method for improving throughput of block chain

Abstract

The invention discloses a system and a method for improving the throughput of a block chain. The system comprises a load balancing module, a preprocessing module, a marking module, a receiving module, a sending module, a dynamic speed regulation module and a consensus module, wherein the preprocessing module, the marking module, the receiving module, the sending module, the dynamic speed regulation module and the consensus module are deployed in a block chain node, the method is characterized by comprising steps of providing a local global counter, wherein counting of the local global counter can be persistent; after the transaction is received, packaging the transaction according to counting of the counter and storing the transaction into local storage; sending a consensus packet to the whole network regularly to enable the whole network to realize constant-speed consensus; the consensus sending speed of the nodes can be adjusted in real time, and comprehensive utilization of computing resources is achieved. The limitation of a single node on the network performance in the block chain network is relieved, the transaction throughput capacity of the network can be greatly improved under the condition that a block chain network consensus algorithm and a network structure are not changed, and the comprehensive utilization rate of whole network computing resources and the network stability are improved.

Description

Technical field [0001] The invention belongs to the field of block chains and distributed systems, and more particularly to a block chain throughput lifting system and method. Background technique [0002] Traditional block chain techniques often use the simultaneous reception when receiving transactions, i.e., pack and broadcast them and broadcast when the node receives a sufficient amount of transaction. This receiving-consensus mode has a good effect in terms of network pressure or the network size is not large, and the timeliness and accuracy of the uploaded transaction can be guaranteed, but this technical solution has the following defects: [0003] (1) When a single node pressure is increased, the consensus speed of the entire network is constrained by a single node, so that the overall consensus speed is slow. [0004] (2) The consensus speed is the same as throughput. When the network scale is expanded, the overall throughput of the network is almost unchanged, and the c...

AI Technical Summary

Problems solved by technology

[0003] (1) When the pressure on a single node increases, the consensus speed of the entire network is restricted by a single node, which slows down the overall consensus speed of the network

[0004] (2) The consensus speed is the same as the throughput. When the network scale expands, the overall throughput of the network is almost unchanged, which seriously wastes computing resources

[0005] (3) Each node receives transactions equally, and the introduction of nodes with poor performance will become a shortcoming of the network, so the overall scalability of the network is poor, and the overall cost is also high
