Problems solved by technology

[0002] The currently existing cross-validation-based on-chain data verification mechanism is to broadcast the data to be on-chain to the entire network, and go to the chain after the entire network reaches a consensus. There are two problems in this way. One is that not all nodes on the entire chain All have verification capabilities, and the other is that a large number of messages will be sent and received during the broadcast process, which will seriously affect the verification efficiency

Embodiment 1

[0029] refer to Figure 1~3 , as an embodiment of the present invention, provides an improved POA consensus method suitable for multi-party verification in supply chain scenarios, including:

[0030] S1: The user submits an application for data uploading to the chain and selects a common verification node with verification capabilities;

[0031] S2: Carry out sharding + PBFT consensus processing based on the submitted data, and reserve authorized nodes for block generation of the current block and backup nodes calculated by the VRF random algorithm;

[0032] To clarify, sharding is one of several common methods developers use to increase transaction throughput. Simply put, sharding is a partitioning method that divides computing power and storage workload in a point-to-point network. After sharding, each node no longer needs to be responsible for processing the transaction load of the entire network, but only needs to process its own partition (or called shards).

Embodiment 2

[0066] refer to Figure 4~5 It is another embodiment of the present invention. This embodiment is different from the first embodiment in that it provides a verification test of an improved POA consensus method suitable for multi-party verification in the supply chain scenario. It is a test of the technology used in this method. The effect is verified and explained. In this embodiment, the traditional technical solution is used to conduct a comparative test with the method of the present invention, and the test results are compared by means of scientific demonstration to verify the real effect of the method.

[0067] Compared with the existing cross-validation method, the verification time of the present invention is as follows: Figure 4 As shown, with the increase of the number of nodes in the existing cross-validation method, the required verification time shows a linear change and continues to increase, while the cross-validation method based on the fragmentation and PBFT c...

Abstract

The invention discloses an improved POA consensus method suitable for multi-party verification in a supply chain scene. The improved POA consensus method comprises the steps of submitting data and selecting verification nodes; performing fragmentation + PBFT consensus processing based on the submitted data, and reserving an authorized node and a standby node; taking the remaining authorized nodes as main nodes of each fragment, fragmenting common nodes with verification capability by using a fragmentation algorithm, and performing Byzantine consensus; and judging the block attribution of the Byzantine consensus result of each fragment. According to the multi-party verification method, the mode that the user autonomously selects the verification node is adopted to improve the efficiency, and while the multi-party verification efficiency is improved, it can be guaranteed that the user can obtain a correct verification result even if the user buys the selected verification node.

Description

technical field [0001] The invention relates to the technical field of multi-party verification under supply chain scenarios, and in particular to an improved POA consensus method suitable for multi-party verification under supply chain scenarios. Background technique [0002] The currently existing data verification mechanism based on cross-validation is to broadcast the data to be uploaded to the entire network, and then upload the chain after the entire network reaches a consensus. There are two problems in this way. One is that not all nodes on the entire chain All have verification capabilities, and the other is that a large number of messages will be sent and received during the broadcast process, which will seriously affect the verification efficiency. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or omissions may be made...
