Embodiment Construction

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention. Products that can achieve the same function are equivalent replacements and improvements, and are included in the protection scope of the present invention.

[0043] The specific method is as follows:

[0044] Step 1: Regulators mainly refer to the management agencies in the supply chain field. After identity authentication, these regulators build a peer-to-peer permissioned blockchain network model. All regulators directly become super nodes in this model, and private and public keys are generated by the model.

[0045] Step 2: The supply chain is mainly composed of the follo...

Abstract

The invention relates to a supply chain data double-chain storage optimization method based on a block chain, which utilizes a permission block chain technology, so that uplink data cannot be tampered, the information transparency is improved, and the problem of information asymmetry is solved. By the network model, point-to-point transmission is achieved. The security risk is reduced through identity permission; due to the double-chain model design of a main chain and an abstract chain, network access nodes can selectively store according to own requirements, so that the problem of waste of block chain storage space is solved to a great extent, and the storage threshold of node network access is reduced; an improved DPoS + BFT consensus mechanism is adopted, so that the consensus block output speed is increased, transactions can still be efficiently confirmed even under the conditions of many nodes in the whole network and large transaction volume, the performance and throughput are improved, and a supply chain system is greatly optimized.

Description

technical field [0001] The model of the present invention relates to the field of licensed blockchain technology and supply chain, and specifically relates to the dual-chain consensus storage model, which allows nodes to freely choose the storage mode, alleviates the storage pressure problem during the operation of the blockchain system, and improves system scalability and transaction throughput. quantity. Background technique [0002] The issue of food safety is a major issue related to people's lives and health, but in such an important field, mistakes have been made frequently in recent years. From Sanlu milk powder to "Clenbuterol", "Gutter Oil" to "Sudan Red", more and more food safety issues touch the fragile nerves of consumers. With the improvement of living standards, people pay more attention to whether the daily dietary intake is safe. Therefore, it is urgent to solve the problem of food safety. [0003] The reason is that there are problems in the circulation o...
