Problems solved by technology

The efficiency of these designs is generally not ideal. The former is not practical because of its poor performance in terms of data throughput and delay. Although the latter has a certain improvement compared to the former, it still has a large confirmation delay and a small transaction throughput

Abstract

The invention discloses an asynchronous block chain consensus method and system for data broadcasting and consensus decoupling. The system comprises: a plurality of nodes; the nodes can be jointly served by a plurality of mutually trusted physical or virtual devices; the method comprises the steps that data broadcasting and data sequence consensus decoupling are carried out, and nodes jointly maintain a plurality of broadcasting protocol instances and a Byzantine consensus protocol; the broadcast protocol is responsible for transmitting certain node data to other nodes, and the Byzantine consensus protocol is responsible for consensus of results of the plurality of broadcast protocol instances; and in the node, a plurality of broadcast protocol instances can be handed over to a plurality of devices in a one-to-one correspondence manner for maintenance, and an execution result of the broadcast protocol is transmitted to the device which is in the node and is responsible for executing the Byzantine consensus protocol. By implementing the method and the device, the efficiency of the block chain system can be improved, and meanwhile, the system efficiency can be more conveniently improved by increasing physical resources.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an asynchronous block chain consensus method and system decoupling data broadcasting and consensus. Background technique [0002] Blockchain technology refers to a technical solution that ensures that all participants jointly maintain a distributed ledger through a consensus mechanism. According to different network model assumptions, it can be subdivided into three types: synchronous, semi-synchronous and asynchronous, of which asynchronous is the weakest assumption. In the asynchronous network model assumption, neither the participants nor the designer can obtain the upper bound of the network delay, which makes the asynchronous blockchain consensus more complicated in design. Most of the existing designs adopt the idea of ​​direct consensus on the data, or first distribute the data, and then agree on the identity of the sender of the data. The efficiency of these designs i...
