Agricultural planting app blockchain

1. The application of blockchain in the field of agriculture is developing day by day. Jiminsheng connects the front, back, left and right blocks of "things" into a chain with one technology, but the original data of each block can not be tampered with. It is a technology of "each mole chain" in the field of Internet of things that can be trusted by participants.

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 decentralization of blockchain will greatly rece the cost of Internet maintenance and enhance the intelligent and large-scale level of Agricultural Internet of things. At the same time, the agricultural procts traceability system based on blockchain technology solves the trust crisis of consumers for procts, and makes people's dining tables healthier and safer
in the field of agriculture, what are the trends of blockchain agriculture
1. Internet of things + UAV + blockchain
logistics ensures the interconnection of everything, UAV provides proction management services, and blockchain provides recording and traceability technologies. It will be concive to the development of precision agriculture, rece pesticide investment and improve the quality of agricultural procts
2. Blockchain + data + artificial intelligence
the application of blockchain in agriculture can eliminate information asymmetry to the greatest extent, improve the information transparency and timely response ability of the whole instrial chain, and realize the value-added of the whole instry
the integrated development of blockchain + data + artificial intelligence can maximize the value of agricultural big data and rece the input cost< In early February, the Chinese government issued "guidance on the revitalization of rural financial services". The new framework proposed this time is part of the financial service efficiency improvement plan in the National Rural Revitalization Plan
blockchain + agricultural finance will provide a convenient way for small farmers' loans and bring authenticity and predictability to the credit investigation of agricultural financial institutions
4. Blockchain + rural logistics
e to the small distribution of rural logistics, package loss and difficulty of agricultural procts ascending are caused. But blockchain technology can solve these problems
5. Blockchain + agricultural supply chain
this kind of application is the reason why major shopping malls graft blockchain. For example, Wal Mart, Carrefour and other large supermarkets bring the whole fresh food and food supply chain into the block chain management, so as to rece costs and improve proct safety. At present, Cargill, an American agricultural giant, is vigorously developing the application of blockchain + agricultural supply chain finance
in addition to agriculture, the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

5. At present, the combination of blockchain and agriculture can be divided into two parts:
one is the traceability mode, which is commonly used nowadays. All agricultural activities, from planting to proction and sales, are recorded on the blockchain, so as to achieve the purpose of proct traceability. However, this method costs a lot, and usually has a special team or company to do it, Because the follow-up after-sales is very troublesome
the second is to use the form of blockchain token combined with the online mall to sell agricultural procts through the Internet. Instead of the usual cash, it uses the form of digital currency to circulate, which is equivalent to linking with the blockchain

6. I saw an agricultural traceability project of dmtc rice before -

is to install an RFID chip on the proct, which records the whole life cycle of the proct, 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 probably like this, so should other traceability procts
you can also ask me if you have any questions, I hope it will help you!

7. The first question is not very clear, but if someone else's platform wants to provide services that are useful to you, it also requires you to go up the chain to let them know that you trust him and that there are still a lot of them, so that they can have the confidence and resources to do this. If you can't get on the chain, it depends on whether you need their service. If their service is good for you, you can get on the chain.

8. What's block company for

9. I don't know, but Shenzhen Nanshan and Shenzhen Huaqiangbei both have SEG electronic markets. You can go to see them.
