区块链 食品安全溯源,基于区块链的食品溯源

近年来，随着社会的发展，食品安全问题日益受到人们的重视，而基于区块链的食品溯源技术也成为越来越多公司重视的一种新技术。今天，我们就来谈谈基于区块链的食品溯源技术，以及它的三个关键词：安全追溯、可信认证和供应链金融。

安全追溯：基于区块链的食品溯源技术是一种利用区块链技术在食品供应链中进行安全追溯的技术。它能够帮助企业追踪食品的生产、流通、消费过程，并实时记录每一步的信息，从而使食品的安全追溯更加可靠、高效。

可信认证：基于区块链的食品溯源技术还可以提供可信认证，以确保食品的安全性。该技术可以通过收集和记录食品供应链中的各种信息，如原料来源、生产过程、检测结果等，从而确保食品的质量和安全性。

供应链金融：基于区块链的食品溯源技术还可以为食品供应链提供供应链金融服务。该技术可以为食品供应链中的各环节提供金融服务，如贷款、保险、票据融资等，从而改善食品供应链的效率和安全性。

总之，基于区块链的食品溯源技术是一种新兴的技术，它可以帮助企业实现安全追溯、可信认证和供应链金融，从而提高食品安全性，保障消费者的权益。

A. What is blockchain and agricultural traceability?

Answer: 1. The connotation of blockchain

Blockchain is a distributed The shared ledger and database have the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

2. The connotation of agricultural traceability

1. Agricultural traceability is the most complex and difficult part of food traceability. Currently, except internationally, there is no traceability based on food safety production and the entire supply chain. A fully integrated agricultural product traceability system that manages both aspects.

2. The most important thing in the construction of agricultural traceability system is "one center and three modules", which is a traceability cloud data center and three modules of producers, regulatory authorities and consumers.

3. Composition of blockchain

The blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

B. What is a food traceability system

Tracing means looking upstream for a new place of origin, which is a metaphor for looking upward for historical roots.
I think this is simply a certain food you buy in the supermarket. By scanning the QR code, consumers can know a series of information from the raw materials, transportation, production and delivery of the product. The traceability system is the information behind this. If there is a problem with this traceability in the food industry, it can accurately search, recall and other operations to ensure quality.

C. What is blockchain traceability technology?

From farm to table, blockchain traceability technology is equivalent to purchasing a liability insurance for the product

Bath crab, clenbuterol In recent years, there have been reports on the market of food added with white lumps (sodium formaldehyde sulfoxylate), poultry feeding hormones, whitening agents added to flour, seafood soaked in formaldehyde, etc., and ripening agents and enlarging agents are sprayed on fruits. , spraying highly toxic pesticides on green vegetables, etc. have made people change their color after hearing it. Food safety and health are becoming more and more important to us, so at this time, blockchain traceability technology emerged - a technology that allows agricultural products to be traced from planting to to selling all traceable technology.

Before figuring out the blockchain traceability technology, we must first understand the difference between "traceability" and "traceability".

"Traceability" includes two meanings: logistics tracking and traceability. People often think of traceability and traceability as the same thing. In fact, what companies care about is tracking (don’t lose the goods), while consumers care about traceability (whether what I bought is safe).
The biggest feature of Sanqing Fertile Farm is its traceability, which is a powerful means to ensure food safety. It starts from the source of planting and controls the source, production and processing, cleaning and disinfection, sub-packaging, packaging, storage, transportation, sales and other links.

In short, to be precise, food traceability is a cost and an essential early investment, which is equivalent to purchasing a "liability insurance" for your product. Maybe you won't see the effect for a year or two, when you really use itSometimes, it may be a life-saving straw.
