Recently, the food anti-counterfeiting traceability system formally commercial, Carrefour signed its traceability system for large-scale project construction, mainly to improve food transparency, Carrefour use blockchain technology to build a traceability system, docking the entire production process, to achieve open and transparent supervision.
Blockchain technology will change the financial system for the next 20 years and 30. At the same time, blockchain technology can also be used in other industries, because of the trust, credit and security characteristics of data, the Social credit system is very important.
Not only can improve their product trust level, such as problems can be found in a timely manner, from the future credit and trust era development perspective, Carrefour this time walk in the forefront of the industry.
What contribution can the construction of blockchain traceability system make to social development? What are the advantages and benefits of the blockchain traceability system products to manufacturers? How is the principle of the development and construction of its traceability system?
Using Blockchain for trusted transactions, you can quickly query and trace food sources in a matter of seconds without spending days or weeks. Unlike traditional records-only data systems, blockchain features and the ability to authorize data enable users in their networks to gain higher levels of trusted information. Once the transaction has been recognized by many Parties, it will be given a unique version and cannot be tampered with. It is also to help customers more safe and secure traceability of food or commodities, so that users ' rights and interests are more maximized.
Source in the Rui Blockchain system development, Baidu search consultant, said that "strangers to each other before the trust is mainly produced from their understanding of the extent of their understanding of the more transparent, the greater the degree of trust, people want to protect their rights and interests at the same time, but also to obtain greater rights and interests, and to achieve real fairness, Is the need for all participants to share their responsibilities and obligations ", from the point of view of building a blockchain traceability system for food or commodities, to bring commercial benefits to participants while also bringing safer food or goods.
Why can blockchain break the traditional traceability system?
In blockchain technology, its main features include cryptography, distributed ledger, Intelligent contract, node network and so on. Use these technologies to achieve truly tamper-proof transactions
what shortcomings exist in the traditional traceability system?
(1) Can not be exhaustive, there will always be the omission of the link, such as buyers do not fake, the acquirer may be false, logistics parties, warehouses, distributors, distributors, agents, processing plants and so on may have a party fraud, its track of responsibility is huge, problems are difficult to solve, the enterprise and society will bring great impact. The Blockchain key analogy: it can record a lot of information, his generation is unique, the role of the secret key can be guaranteed to tamper, because there is no way to forge a cottage, copy another secret key out, and the secret key to carry the text picture information is unique.
(2) Risk of liability, the problem is not that all participants are willing to take responsibility, and no one is willing to take the risk, despite the regulatory or legal intervention, everyone in the industry is more than a few things. and distributed ledger records is to solve this problem, everyone has a secret key address, through the distributed storage and synchronization of the ledger technology, a party to publish information or upload pictures, all the other keys will be the information recorded once, in the blockchain industry is also called mining, accounting. Anyone who has a hard record is rewarded more.
The blockchain traceability system is not clear whether the information uploaded is true or false, but if you want to modify information system will send instructions to all nodes, some people want to modify their ledger, really in the responsibility of the time can also be in everyone's ledger to determine who is responsible, if the false become a fact, can not change its information.

How to make blockchain traceability?
From production to sales there are too many links, any commodity will go through a complex process, a lot of people to take over, the key lies in its link node, we can give those nodes to set the secret key, the key is like a blockchain wallet, the above carries the details of its goods, people and things will be the key mark. Source-Rui Blockchain development consultant, mobile phone or v search front 138 middle 2315 back 3926 directly ask to understand that the specific construction of the blockchain traceability system needs to be discussed in detail with the developers. As a developer of early blockchain system, we use blockchain technology to build a centralized blockchain traceability platform system, provide safe and traceable product solutions, enhance the trust of users, we have a professional research and development team, solve all aspects of the blockchain system, and build a project in line with long-term development. Every information transmission, trading, location change of a product is recorded on the blockchain and is real and effective, which is the smart contract.
What is the blockchain traceability smart contract?
For example, the merchant takes the consumer's order to receive, this is a contract, the merchant delivers the goods to the logistics is also a contract, the logistics carries the goods to the designated storefront, the store receives also will have a contract, in the entire link transportation, the production process, has numerous contracts to contract, but this series of contract construction to the chain, Complete on the chain is done through the concept of its smart contract.
Carrefour is a blockchain traceability system commodity landing, the future there are all kinds of goods will fall, the source of the blockchain itself is to give the public a transparent regulatory environment for businessmen can also let their users trust themselves, blockchain traceability to add a trust between strangers.
Carrefour uses blockchain, traceability system principle development
