Quality traceability of agricultural products based on blockchai

1. It can provide information of procing area for consumers and make people feel more at ease.

2.

A: first, the connotation of blockchain

blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

Agricultural traceability is the most complex and difficult part of food traceability. At present, there is no complete agricultural proct traceability system based on food safety proction and whole process supply chain management

2. The most important part of the construction of agricultural traceability system is "one center and three moles", which is a traceability cloud data center and three moles of procers, regulators and consumers

Third, composition of blockchain

blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer

3. I have seen a dmtc rice agricultural traceability project, qisheng
that is, an RFID chip is installed on the proct to record the whole life cycle of qisheng, which is equivalent to that every commodity has an identity tag. These data will be linked in real time and form a tamperable information to ensure the safety and traceability of goods
my understanding is about this, and so should other traceability procts

4. The existing conditions can't handle such a large-scale liquidation, but with the blockchain system, the confirmation of the right of each transaction is fixed. The liquidation only needs to be carried out according to the existing results, and there is no need for review. A lot of manpower and material resources are saved in the process, and the speed of liquidation will certainly be greatly increased, which is determined by the non tamperable characteristics of the blockchain, For example, Nanjing Rongze has a similar block chain inclusive financial platform.

What is blockchain? Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about network transactions of bitcoin, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

and traceability blockchain is a technology based on the nature of blockchain, which is to improve people's quality of life and food safety. Now there are all kinds of traceability, from pig traceability, to dmtc's Agricultural traceability , and then to cosmetics traceability, which are all around this commodity closely related to our life

6. Dmtc mainly uses blockchain technology to integrate the resources of agricultural supply chain, combined with the support of soft and hard chain technology, so as to realize the whole process of agricultural organic food proction record, check, tamper proof and traceability, and thoroughly solve the practical problems of agricultural development. It includes data acquisition, data security and data sharing
in terms of data collection, through artificial intelligence and Internet of things technology, dmtc runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data, proction process data, transportation, sales and consumer behavior data of agricultural procts

in terms of data security, the existing traceability IT architecture is used to maintain the security of the system through network equipment and Agricultural Internet of things (IOA)
in terms of data sharing, the data collected in the whole process of dmtc can be conditionally shared with users in the whole supply chain of ecological agriculture, and the proction and transportation data can be shared with consumers, so as to trace the origin and development of procts, guide agricultural procers to adjust proction direction and improve proction efficiency.
