食品追溯区块链

近年来，随着区块链技术的发展，食品追溯也受到越来越多的关注。本文将介绍区块链技术在食品追溯中的三个关键词：食品安全、供应链可追溯性和食品质量控制。

食品安全：食品安全是指食品在生产、加工、经营、储运、检验等过程中，不会对人体健康造成危害，也不会损害消费者的利益。区块链技术可以有效地解决食品安全问题，它可以把食品的生产、加工、经营、储运等过程中的信息和数据都记录在区块链上，以此来保证食品安全。此外，区块链还可以为消费者提供更多的信息，以便他们能够更好地了解食品的产地、原料、生产和加工等信息，从而确保食品的安全。

供应链可追溯性：供应链可追溯性是指在食品供应链中，能够追溯食品的生产、加工、经营、储运等过程中的信息和数据。区块链技术可以有效地支持食品供应链的可追溯性，它可以把食品的生产、加工、经营、储运等过程中的信息和数据都记录在区块链上，以此来保证食品供应链的可追溯性。此外，区块链还可以提供更多的信息，以便消费者能够更好地了解食品的产地、原料、生产和加工等信息，从而确保食品供应链的可追溯性。

食品质量控制：食品质量控制是指在食品生产、加工、经营、储运、检验等过程中，确保食品质量的控制。区块链技术可以有效地支持食品质量控制，它可以把食品的生产、加工、经营、储运等过程中的信息和数据都记录在区块链上，以此来保证食品质量的控制。此外，区块链还可以提供更多的信息，以便消费者能够更好地了解食品的产地、原料、生产和加工等信息，从而确保食品质量的控制。

总之，区块链技术在食品追溯中，可以有效地解决食品安全、供应链可追溯性和食品质量控制等问题，从而确保食品的安全和质量。

① How blockchain is applied to the food chain

Summary

Chefs can make sure their food is sustainably sourced and organic through blockchain technology. How to make sure of that? IBM thinks the solution lies in Blockchain. IBM is connecting all players in the global supply chain from farmers, procers, suppliers, manufactures in a secure shared platform---blockchain.

Blockchain is a decentralized ledger where activities throughout the whole food supply chain are recorded, verified, and become immutable at each step. This technology applies to any numbers of vegetables from fresh to packaged.

It has three advantages :

Consumers can scan the code on the package to check where the food comes from and whether it is genuinely fresh etc.

It can remove the distributor in the middle. < br />
Traceablity (one of the functions of blockchain) can help spot the problematic food instead of decimating the whole farm in case of a food-born outbreak

Blockchain is a decentralized distributed ledger. All transaction data on the entire chain can be recorded and identified in the ledger and turned into Immutable evidence. The application of blockchain in the field of food supply has three major advantages:

1. Because every step of food from farm to table is recorded on the ledger, the information is traceable. Consumers can obtain the source information of food by scanning the code.

2. Because every step of the transaction and information is open and transparent, trust in the supply chain is increased, and the middle agent between the farmer and the purchaser can be eliminated.

3. Because the information is traceable, if a certain food causes mass poisoning/disease spread, the problem food can be accurately found and the accidental killing of other healthy foods can be reduced.

② With this certification (ant blockchain traceability), is it really authentic?

No, it can only prove that the product has a traceable identification (ID) , if it is assumed that all counterfeit and shoddy products cannot obtain this identification, then all genuine products have traceable IDs.

And the binding between a traceability logo and a product is not unique and unbreakable! The key is that the logo is on the block, but the product is not! In other words, a logo can also be used for counterfeiting. Increasing the difficulty of marking can raise the threshold for counterfeiting, but it cannot completely eliminate it!

Blockchain can only protect digital assets. If you want to protect commodities, the higher the social cost, the more difficult it will be to overcome it. Because commodity protection requires relevant social investment. In fact, the fact that this matter is attached to the concept of block chain is pure speculation! There are no block chains, and the classic technology stack has many solutions for traceability identification!

Is blockchain + anti-counterfeiting traceability necessary?

Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is a series of data blocks generated by using cryptographic methods. Each data block contains a change of hands. or transaction information.

It can be used in the food sector so that each party in the supply chain (producers, processors and distributors) can provide traceability information about their specific role (such as date, location, farm construction, distribution channels).

At present, among the many application fields of blockchain, blockchain food traceability and anti-counterfeiting is currently one of the most promising blockchain fields.

The reasons can be summarized in three aspects:

First, for consumers, this technology will meet their growing demand for food quality transparency;

< p>The second is that for food suppliers (breeders), this is a means to demonstrate the high quality and professionalism of their products;

The third is that the technology is easy to promote and use, and the outer packaging of each product Each will include a QR code that consumers can scan using their smartphones, eliminating the need to purchase additional equipment.

③ What is blockchain? In addition to food traceability, what other common applications does blockchain have?

Save production and distributor costs, use blockchain technology and material Networking can realize automated data collection and storage, reducing labor investment and other equipment investment; in addition, the application of blockchain technology and the Internet of Things can help manufacturers and distributors reduce various expenditures and reduce the price of agricultural products, thereby realizing customer satisfaction. profit.

The key to blockchain technology is a distributed digital ledger that can store all types of information, including cryptocurrency transactions, NFT usage rights, and DeFi blocks chain.

Although any traditional database system canIt is not enough to store this kind of information, but digital currency is unique in its complete blockchain technology. In contrast to systems maintained in a core organization by central administrators (such as Excel spreadsheets or bank database systems), blockchain databases have many identical copies stored on multiple computers that exist on the network, but these independent electronic Computers are called connection points.

The name "blockchain technology" is not a whim. Data ledgers are generally described as "chains" composed of separate "data blocks". When new data is imported into the network, a new "block" is created and added to the "chain," which involves all nodes updating their versions of the blockchain ledger so that they are the same.
