Description
Technical field
The present invention relates to milk supply trace field, is a kind of milk supply traceability system based on block chain technology.
Background technology
As the fast development of China's economy and the rapid of living standard of the people improve, demand and concern to food
In terms of quantitative aspects turns to quality, the safe and healthy problem of food has been mentioned unprecedented height.In recent years I
State's dairy industry shows the growth momentum that both production and marketing thrive, but the quality and safety level of dairy industry is low, and dairy safety event frequently occurs,
From Fuyang inferior milk power event to light recycling milk event again to the exceeded events of Mongolia Ox aflatoxins M1, the safe thing of quality of dairy products
Therefore take place frequently, it is serious to have hit confidence of the consumer to quality of dairy products safety, while the health for also influencing China's dairy industry is held
Supervention exhibition.Therefore, quality of dairy products level of security is improved, the consumption safety for ensureing vast urban and rural residents has important meaning
Justice.
Since quality of dairy products problem is likely to occur in the cultivating link of cow, the production link of raw material milk, dairy products
The dispatching link of processing link, dairy products, so, ensure the quality safety of dairy products, security risk is reduced as far as possible, not only
Need the promotion in policy, it is also necessary to the support of correlation technique.Block chain technology can be followed the trail of in milk cattle cultivating production, dairy produce
Production and the loophole in the whole link of circulating, if there is problem, are also easy to investigate thoroughly the ins and outs of whole case.
The content of the invention
In view of this, the present invention provides a kind of milk supply based on block chain technology for solving or partly solving the above problems and chases after
Trace back system.Include herein below：
A kind of milk supply traceability system system based on block chain technology includes aquaculture management node, processing node, fortune
Defeated management node and query node；Participant includes agriculture and animal husbandry field, dairy industry company, logistics provider, consumer and supervision department；
Participant participates and draw a intelligent contract jointly；Contract is spread by P2P networks and is stored in block chain network；Area
The intelligent contract automated execution of block chain network structure；First engage in the user for being first registered as block chain network, block chain network
Return to participant a pair of public key and private key；Account address of the public key as participant in block chain network, private key is as behaviour
Make unique key of the account；Participant has decided through consultation a promise jointly, and rights and duties are included in promise；Participant is used respectively
Respective private key is signed, it is ensured that the validity of contract；Intelligent contract after signature, it will according to promise content therein, pass
Enter in block chain network；Intelligent contract is spread by way of P2P in block chain network the whole network, and each node can receive one
Part；
Aquaculture management node, processing node and transportation management node together decide on the generation of intelligent contract；To dairy produce
Record is signed in detail, and the detailed record of dairy produce includes milk cattle cultivating information, dairy produce production information and transit information；With
Time stepping method, the node noted down in detail of dairy produce is write while is responsible for the renewal recorded in detail of dairy produce；Node can be
All contracts preserved in a period of time recently, are packaged into a contract set, and calculate the Hash of this contract set together
Value, is finally assembled into a block structure by the hash value of this contract set, is diffused into the whole network；Other nodes receive this area
After block structure, the Hash for the contract set that the inside includes can be taken out, compared with the contract set that oneself is preserved；At the same time
The contract set of oneself a accreditation is sent to other nodes；By this transmissions taken turns and compare more；All nodes are most
Reach an agreement before the deadline to newest contract set eventually；The newest contract collection credit union reached is spread in the form of block
To the whole network, each block includes following information：The hash value of current block, the hash value of previous block, when reaching common understanding when
Between stamp and other description informations；The most important information of block chain network is to carry one group of contract reached common understanding at the same time
Collection；The node of contract collection is received, every contract can all be verified, the contract being verified just finally writes block chain network
In, the content of verification is mainly whether the private key signature of contract participant matches with account；
Aquaculture management node is agriculture and animal husbandry field, and agriculture and animal husbandry field writes supply of forage business examination ＆ verification, animal health condition, milk cow medication feelings
The information such as condition and environmental statement；Processing node is dairy industry company, write former milk receiving time, former milk storage condition, product batch number,
Processing staff and owner information；Transportation management node is logistics provider, and writing the environment such as the temperature in transportational process, humidity will
Ask, the unloading information of home-delivery center, inventory information etc.；
Consumer and supervision department, can participate in business, but keep aloof from accounting procedure, can be carried out by open API
Limit and inquire about the conditional read right of general node tool, the read right of limitation is only to belong to the permission of same manager
Under, the detailed of dairy produce that could read the manager for the belonging to same communication network write-in stored in block chain network is remembered
Record.
The present invention useful achievement be：, can the present invention provides a kind of milk supply traceability system based on block chain technology
Follow the trail of in milk cattle cultivating production, dairy produce production and the loophole in the whole link that circulates, if there is problem, be also easy to investigate thoroughly
The ins and outs of whole case.
