The field of food traceability continues to increase, and the "first traceability" needs to use the blockchain to realize the traceability of agricultural products

As far as the current food market is concerned, people have a low degree of trust in issues such as product origin, pesticide residues, and food quality and safety. From the perspective of production, the integrity value of production and suppliers cannot be reflected. Consumers cannot quantify the pros and cons of production and suppliers in terms of product quality.
Traceability + blockchain is the combination of traceability technology and blockchain, so that the information of a series of links such as the production, transportation, and transaction of agricultural products can be uploaded to the chain, and the whole process can be traced. Each piece of information is unique and attached to each subject. digital signature and timestamp for consumers to query and verify.
What are the advantages of the combination of blockchain and traceability technology? It enables consumers to understand the whole process information of the product more clearly, and ensures the authenticity of the information on the chain.
Odaily has recently come into contact with a project that combines traceability of agricultural products with blockchain, the first traceability technology.
The specific traceability technology of the first traceable production link is divided into three categories:Traceability by product, batch by batch, and one item by code.For product traceability, it is necessary to add the product code corresponding to the SKU on the package; for traceability by batch, it is to scan the code to select the production batch number to obtain further batch information; content. Provide different traceability methods, which can effectively reduce the time spent in the traceability process and improve the efficiency of information collection.
In the product circulation link, Shoutui proposed a retrospective quantitative certificate, that is, to provide a certificate based on the product quantity in the previous link. If the product is faked in a certain link, some counterfeit or defective products will be provided, and the genuine product will have no certificate and cannot be circulated.
In the sales of agricultural products, Shoutrace Technology will also adopt the model of mall + blockchain, and through the establishment of cooperation with the Liaocheng government of Shandong, launched an agricultural product mall. The next step is to build an online mall combined with blockchain technology. Let C-end users perceive the value of blockchain traceability in life scenarios.
At present, Shoutrace is developing the alliance chain, and there are more than 50 large and medium-sized production enterprises on the chain, and more than 1,400 small production entities such as cooperatives.
Why do companies choose to go on the chain, or even become a node?
Founder Wei Lei said that the first system has established an incentive scoring mechanism, and enterprise data on-chain can accumulate credit scores and improve competitiveness. Second, most of the farmers who plant and breed are of the younger generation. They are happy to see their products realize the process of information transparency, improve the trust of consumers, and enhance their purchasing power.
Even if the traceability + blockchain scenario is very suitable, it still faces many problems. Due to the need to maintain the complete transmission of information, each enterprise in the entire process needs to be chained. So how to let more enterprises join the ecology and lower the threshold of data collection and on-chain is very important.
But for now,Domestic technology is still unable to achieve fully automatic Internet of Things technology collection and on-chain,It is only extensive planting or partial scale production, or only partial scale smart farms with Internet of Things technology. Human-intensive issues such as information entry still need to be addressed.
Another problem that exists is that the blockchain can guarantee the authenticity of the chain, but how to ensure the quality of the products before the chain. Wei Lei said, "The pre-chain data is not isolated. It is the first to construct a multi-role system ecology. All nodes on the chain are connected. Interconnected data can be mutually verified by multiple parties. Reduce data fraud. Secondly, The system will degrade, downgrade, or even ban the account of the responsible subject."
However, it is undeniable that even if there is strict management, there are still fraudulent behaviors, which can be avoided as much as possible, but there is no guarantee of 100% authenticity.
There are currently 28 people in the Shoutrace technology team. The founder, Wei Lei, is a master of information security at Peking University. He has started his own business many times. He once established an agricultural product demonstration base in Beijing Fengheyuan (National) Modern Agriculture Demonstration Zone to conduct research on agricultural product traceability. Jiang Yong has served as the technical director of many companies; Wang Yuexiang, the head of blockchain finance, graduated from the Finance Department of Tsinghua University and has served as the strategic director of many large financial institutions.
