Problems solved by technology

This method greatly improves the scalability of the Byzantine fault-tolerant protocol, but the leader node becomes the bottleneck of system performance, because the efficiency of the Byzantine fault-tolerant protocol based on the leader node depends largely on the performance of the leader node. For example, the calculation rate of the leader node, the network delay, bandwidth and storage space for interacting with other nodes, etc.
Therefore, these protocols are no longer practical when there is a large number of nodes in the system
[0007] The second is the transmission of large batches of messages
This is a very simple and effective solution, but if the request batch size is too large, the transmission time of the message will cause the delay of confirming the request to increase sharply, and the throughput of the system will also drop sharply

Abstract

The invention discloses a multi-role-driven pipeline consensus method and system, which are divided into a proposal flow and a consensus flow. In the proposal flow, a leader node continuously initiates a consensus proposal of a transaction block. In the consensus flow, all consensus nodes exchange messages, process a series of consensus proposals from the leader node through pipeline work, and reach a consensus on the transaction blocks in the proposal. As a result, the rapid and positive response to consensus messages can be realized, and the delay of transaction confirmation can be reduced; the scalability of the system can be enhanced, and the transaction throughput of the system can be improved.

Description

technical field [0001] The invention relates to the technical fields of information security and electronic commerce, and in particular, to a multi-role-driven pipeline consensus method and system. Background technique [0002] In a distributed system, arbitrary behavior of Byzantine faulty nodes can bring serious damage to the system. In order to allow distributed systems to operate normally in the presence of Byzantine faults, a number of Byzantine fault-tolerant protocols have been proposed by the academic community. Byzantine fault tolerance protocol is designed to solve the problem of state machine replication, that is, in the presence of Byzantine fault nodes in a distributed system, all honest nodes can agree on a series of requests in the same sequence. [0003] PBFT (Practical Byzantine Fault Tolerance, Practical Byzantine Fault Tolerance) is the first Practical Byzantine Fault Tolerance protocol using the full broadcast message mode. In the PBFT protocol, the onl...
