Problems solved by technology

It is difficult for data to be interconnected in a timely and effective manner among the various links in the rice supply chain, and there are security risks in the data interaction between the blockchain and the local database
[0006] (2) Due to the large number of links in the rice supply chain, the complexity of the participants, and the huge amount of rice circulation, the amount of data generated by the rice supply chain is huge
The storage space of the blockchain itself is limited, and the single-chain model cannot bear the huge amount of data in the rice supply chain, and has problems such as high latency and high storage costs
[0007] (3) The data storage of the rice supply chain is decentralized, the basic information of each link, the information of harmful substances, and the identity information of personnel are weakly related. Fraud is difficult to effectively monitor

Embodiment

[0142] According to the different types of data stored in each parallel chain, the present invention sorts out more than 200 types of key data according to relevant national / local / industry standards, data actually generated in each link of the rice supply chain, and the like. The data covers the whole process of rice from planting to consumption. It also stipulates that 9 parallel chains correspond to harmful substance information, enterprise information, consumer information, regulatory agency information, transaction records, cost information, data interaction records, hygiene records and other information. The key data generated by each batch is classified as follows. Table 1 shows:

specific Embodiment

[0155] The experimental simulation of the designed rice supply chain multi-chain supervision mode is carried out, and a cloud server is adopted, and the server is configured with 4-core CPU, 8G memory and 50G high-performance cloud hard disk. The cloud server has 32 nodes, 8 of which are used as main chain nodes, corresponding to the representative enterprises and 2 regulatory authorities in the 6 main links of the rice supply chain. 6 are arranged as relay chain nodes, and the relay chain game adopts CFR (virtual regret minimization algorithm). The remaining 18 nodes build 3 parachains, and each parachain deploys 6 nodes, corresponding to the stored enterprise information, supervisor information and cost information. The correctness of cross-chain transmission in the multi-chain supervision mode of rice supply chain is tested by setting different malicious nodes and wrong nodes respectively. The test set is divided into 3 groups, and the number of faulty nodes in each group ...

Abstract

The invention discloses a rice full supply chain information supervision method based on a parallel block chain and a smart contract, and relates to the field of rice quality safety. A rice supply chain information supervision model architecture is divided into three block chains including a main chain, parallel chains and relay chains, and different types of data are stored in different parallel chains; an acquisition cross-chain mechanism and a supervision cross-chain mechanism based on Hash locking, an intelligent contract and a relay chain are provided, a concurrence mechanism based on a K-means algorithm and a Bloom filter and an SPBFT consensus mechanism suitable for multi-chain consensus are used, and a rice supply chain supervision cross-chain mode is constructed. According to the method, the coupling of different types of data among the links of the rice supply chain is increased, the convenience and safety of data interaction among the links of the rice supply chain are improved, the storage cost of the data of the supply chain and the high delay of interaction are reduced, fine management of the data of the rice supply chain and personnel is realized, and the management efficiency is improved. The food quality safety of the rice is ensured.
