Problems solved by technology

However, they all have scalability problems. At the same time, traditional algorithms such as Paxos and Raft are not suitable for Byzantine fault-tolerant environments. Therefore, we propose a cross-fault-tolerant method for consortium chains to solve the above problems

Embodiment Construction

[0056]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0057] refer to Figure 1-9 , a cross-fault-tolerant method for consortium chains, including the following steps:

[0058] S1. Implement XRaft sorting backend in Fabric;

[0059] S2. Each XRaft Orderer group elects its own Leader node, and then the Leader in each group sends the Leader identification message of the group to the next group in a clockwise direction

[0060] S3, run the XRaft algorithm among the councilors to generate their own Leader nodes;

[0061] S4. The internal fault handling of the shard master cluster will notify the Leader of the group where the faulty node is located to re-elect a new member node;

[0062] S5, processing load and failure; ...

Abstract

The invention relates to the technical field of block chain application, and discloses an alliance chain-oriented cross fault tolerance method. The method comprises the following steps: realizing XRaft sorting back end in Fabric; in each XRaft Order group, performing electing to generate a Leader node of the XRaft Order group, and then enabling a Leader in each group to generate a Leader identification message of the group to a next group clockwise; and operating an XRaft algorithm among the negotiators to generate own Leader nodes. According to the method, a specific fault node can be positioned, so that the fault node is simply isolated into a Passive node, the fault recovery speed is improved, the change of global configuration information is reduced, consistency check is carried out in a small range, and the complexity of algorithm view change is reduced.

Description

technical field [0001] The invention relates to the technical field of block chain applications, in particular to a cross-fault-tolerant method for consortium chains. Background technique [0002] With the gradual expansion of the application scope of blockchain (Blockchain, also known as distributed shared ledger), it has received extensive attention from the industry and academia. As a distributed system, blockchain can be divided into public chain, alliance chain and private chain from the perspective of access control. The consensus algorithm plays a decisive role in maintaining data consistency and ensuring system security and reliability in a distributed system. At present, non-deterministic algorithms such as PoW are basically used in the public chain, and PBFT series deterministic algorithms are mainly used in the alliance chain and private chain. However, they all have scalability problems. At the same time, traditional algorithms such as Paxos and Raft are not su...
