Blockchain agricultural ppt

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. 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.

4. For example, the vonetracer traceability system of wangchain technology can record the information of planting links from the purchase of seeds / fertilizers, sowing, irrigation, fertilization and other systems to the information records of picking and testing, and collect and monitor the whole process data according to different batch numbers, so as to realize the traceability management of planting link information.
