Description
Technical field
The present invention relates to a kind of traceability systems, and in particular to a kind of chicken cultivation traceability system and side based on block chain technology
Method.Belong to food safety trace back administrative skill field.
Background technique
Chicken cultivation has very long history, as the improvement of people's living standards, quality safety of the people to cultivation chicken
Increasingly pay close attention to.Be confined to technology development in the past, in breeding process the monitoring intelligent, information platform of many links also in
More original and passively state, it is main or by being manually monitored and information exchange, either information it is comprehensive also
It is that reliability is had a greatly reduced quality.
In the growth course of chicken, the breeding environment of chicken, real-time feed intake, mass motion amount etc. will have a direct impact on chicken
Meat undoubtedly can be convenient for consumption if consumer is capable of the entire breeding process of the selected chicken of scene understanding when buying chicken
Person selects, and from the explanation of sellers' mouth parched and tongue scorched, can also promote the success rate of dealing, but food tracing information is comprehensive
Property, accuracy and authenticity be the bottleneck for restricting food safety trace back always.
Block chain technology is very popular in recent years, is a kind of novel decentralization agreement, can safely store digital goods
Coin transaction or other data, information can not be forged and be distorted, and can be performed automatically intelligent contract, without any centralization mechanism
Audit.Decentralization and by way of going to trust, collective safeguards authentic data library to block chain, and there is decentralization, distribution to deposit
Storage, encryption and it the characteristics such as can recall.
Block chain is calculated and is stored using distributed, and there is no the hardware of centralization or management organization, the power of arbitrary node
Benefit and obligation be all it is impartial, data block in system is safeguarded jointly by having the node of maintenance function in whole system.Area
The basis of block chain is distributed network, and the data generated on each node are broadcast to other nodes by distributed network, other
Node is by proof of work come the authenticity of verify data.
If block chain technology is introduced into the monitoring of chicken breeding process, spy can not be distorted using block chain
Point, so that the reliability of traceability system greatly promotes.
Summary of the invention
