Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0042] The present invention provides a novel blockchain consensus method based on shared storage, such as figure 1 As shown, this method introduces a shared storage message passing mode and a mutual exclusion competition mechanism, which has the characteristics of large throughput, short consensus time, and good fault tolerance. This technology provides a new idea for the node consensus problem in the blockchain network. And to a certain extent, it avoids the problem of bifurcation and waste of resources in the blockchain network.

[0043] Such as figure 2 As shown, the specific examples are as follows:

[0044] A new blockchain consensus method based on shared storage, comprising the following steps:

[0045] S1. Leader election phase:

[0046] S11. If the validator nod...

Abstract

The invention discloses a novel blockchain consensus method based on shared storage. The novel blockchain consensus method comprises the following steps: S1, a leader election stage: selecting a unique leader node from validator nodes through mutual exclusion based on the shared storage; S2, a block generation stage: generating a corresponding new block by the leader node generated in the electionstage, and notifying other validator nodes to carry out verification and the leader node to check a result generated in the verification stage; S3, a block verification stage: verifying the new blockby the validator node in the system; S4, a blockchain updating stage: enabling a leger node and a validator node in the system to access the verification information to determine whether to update the local blockchain or not to achieve a consensus. The method has the advantages that a shared storage mode is used for replacing a traditional P2P communication mode, a unique leger node is selected through a mutual exclusion algorithm, resource waste caused by selection of a main node of a transmission block chain can be avoided while the information transmission frequency is reduced, and the whole block chain network achieves consensus at low cost.

Description

technical field [0001] The invention belongs to the field of block chain consensus, and in particular relates to a consensus method in a block chain that introduces a shared storage mode. Background technique [0002] Currently, the mainstream consensus algorithms used in the blockchain include Proof of Work, Proof of Stake, Delegated proof of stake and Practical Byzantine Fault Tolerance. . [0003] The proof-of-work mechanism (PoW) is a consensus algorithm used in the Bitcoin network. It was proposed by Satoshi Nakamoto. Its idea can be summarized as obtaining specified results through work, and using the results to prove the efforts made. The consensus process is that the node uses its hash computing power to find a random number that meets the requirements. Once the Nonce that meets the requirements is found, the node will broadcast the result to the network, and other nodes will verify whether the received random number meets the difficulty requirements. It proves tha...
