Problems solved by technology

At the same time, because there is not enough data recognized by multiple parties, the credit evaluation of the acquirer cannot be established
At present, the food products on the market are basically impossible to trace
Deprives consumers of confidence in the original source of the product
When a safety problem occurs, the regulator cannot accurately check which step the problem occurred
[0003] At the same time, the relevant subsidies in the food sector are usually aimed at a certain item or a certain group, and it is impossible to provide precise subsidies for relevant links in the entire industrial chain, and the incentive effect is single
The safe distribution of subsidies itself is also a time-consuming and costly process

Embodiment 1

[0096] like Figure 4 As shown, the acquisition scenario process:

[0097] SG1. The purchaser enters the product to be purchased, price, and purchase volume in the mobile app;

[0098] SG2, the farmer opens the QR code in the mobile app; if the farmer can use the app of this system, go to step SG3, otherwise skip to step SG4;

[0099] SG3. The acquirer scans the QR code in the farmer's mobile app. Go to step SG5

[0100] SG4, the purchaser scans and inputs the mobile phone number of the farmer, and then goes to step SG5;

[0101] SG5. The transaction is completed, and relevant information is reported from the mobile phone to the trading platform system;

[0102] SG6, the transaction platform subsystem stores the transaction information into the blockchain;

[0103] SG7. The transaction information is distributed by the P2P network to the granary, supervision and other nodes on the blockchain;

[0104] SG8. After the granary and supervisory nodes confirm that the transact...

Embodiment 2

[0109] like Figure 5 As shown, the implementation process of reward token transfer algorithm:

[0110] MB1, the payer (personal account, or other smart contracts such as SG9) initiates a transfer payment proposal from account A to account B through the reward token management module on the node;

[0111] MB2, the proposal is broadcast by the whole network through the P2P protocol between subsystem nodes;

[0112] MB3, all parties in the network query the information of account A on their nodes to determine whether the transfer is legal (such as whether the account has sufficient balance, whether it is frozen, etc.);

[0113] MB4. Reach a consensus on the success of the transfer when all parties in the network confirm that the notebook is legal;

[0114] MB5, ​​the consensus will be broadcast by the payer node to the entire network, each node confirms that the consensus is effective, modifies its own local ledger, and records the transaction;

[0115] MB6. If the consensus ...

Embodiment 3

[0118] like Image 6 As shown, the algorithm flow of the purchase and storage process:

[0119] SC1. The acquirer delivers the grain to the granary, and after the granary checks, enters the relevant information from the purchase platform into the corresponding transaction order, among which,

[0120] SC1-1. If the grain quality or delivery time does not meet the requirements of the granary, the granary will trigger the credit contract, deduct 10 points from the purchaser's credit score, and the purchase will be terminated;

[0121] SC1-2. If Granary chooses to add points to the purchaser, it can increase the value of the purchaser's credit score through the platform;

[0122] SC2. The transaction information is sent by the acquisition platform to the blockchain through the PeerNode interface module to indicate the completion of the transaction.

[0123] SC3, the blockchain platform broadcasts the status of the transaction to other nodes through the P2P protocol;

[0124] SC...

Abstract

The present invention relates to a blockchain-based method and system for traceability and incentives of grain safety. The present invention can know the accurate source of grain origin for granary harvesting; for purchasers, it can encourage them to be recognized by all parties through honest operation credit evaluation, so as to better harvest grain; for farmers, they can get certain market feedback and bonuses to encourage them to hand in grain well and quickly, find reputable purchasers to sell grain, and continuously improve planting technology, and Choose better varieties; for regulatory authorities and end users, product traceability can be used to inquire about the specific purchase, storage and circulation process of grain raw materials; for grain product manufacturers, they can obtain complete grain circulation data to improve their market competitiveness ; For the food sector, reward tokens can be used to make relevant food subsidies more effective and maximize the economic benefits of subsidies.

Description

technical field [0001] The present invention relates to the technical field of grain block chains, specifically a method and system for traceability and incentives of grain safety based on block chains. Background technique [0002] At present, it is generally the purchasers who purchase grain from farmers. The purchaser then transports the grain to the grain depot for storage. In this link, the grain depot is not very clear where the grain of the purchaser comes from. At the same time, because there is not enough data recognized by multiple parties, the credit evaluation of the acquirer cannot be established. At present, the food products on the market are basically impossible to trace. Make consumers unable to have confidence in the original source of the product. When a safety problem occurs, the regulator cannot accurately check which step the problem occurred. [0003] At the same time, the relevant subsidies in the food sector are usually aimed at a certain item o...
