Application of blockchain in traceability of agricultural produc
the traceability of blockchain technology is used to increase the traceability and security of commodities through the deep combination of logistics management, commodity anti-counterfeiting, commodity traceability, manufacturing management, instry collaboration and other fields. Password finance, focusing on blockchain information.
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 management2. 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
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
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
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.
