Problems solved by technology

The problem with this commonly used deployment solution is: when the number of downtime in the computer room exceeds 1, the network failure will cause more than 1 / 3 of the nodes to fail to operate normally, and the entire blockchain system will not be able to continue to reach a consensus, resulting in system paralysis. continue to operate normally

Embodiment Construction

[0065] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0066] Such as figure 2 as shown, figure 2 It is a schematic diagram of the system architecture of an embodiment of the blockchain disaster recovery system of the present invention.

[0067] In this embodiment, the blockchain disaster recovery system is suitable for blockchains based on the practical Byzantine fault-tolerant consensus algorithm. The blockchain disaster recovery system includes: a first computer room 2, and the first computer room 2 At least one second computer room 3 connected by communication (this embodiment is described by setting up a second computer room 3), a backup computer room that is respectively connected to the first computer room 2 and each of the second computer rooms 3 4, and the ...

Abstract

The invention discloses a block chain backup for disaster recovery system, method, server and a computer readable storage medium. Block chain nodes are deployed to a first primary machine room, a standby machine room and at least one second primary machine room. When the downtime node amount is greater than the fault-tolerant capacity theoretic value of the practical Byzantine fault-tolerant algorithm, the standby machine room is started through the block chain backup for disaster recovery server to perform the backup for disaster recovery. Compared with the prior art, the system availabilityof the system is guaranteed while performing the backup for disaster recovery of the block chain.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain disaster recovery system, method, server and computer-readable storage medium. Background technique [0002] Practical Byzantine Fault Tolerance consensus algorithm (PBFT, Practical Byzantine Fault Tolerance) is a mainstream consensus algorithm in the blockchain system. The algorithm has high consensus efficiency and has the characteristics of fault-tolerant node failure or malicious attack. The nature of the algorithm itself ensures that when the total number of nodes N=3f+1, the correctness of the consensus result will not be affected, that is, when the total number of invalid or malicious nodes f is less than 1 / 3 of the total number of nodes N in the blockchain system, the overall block The chain system can still continue to operate normally. refer to figure 1 , in the blockchain system scheme based on the PBFT consensus algorithm deployed online, ...
