In conjunction with the introduction of system above, the agricultural product information maintaining method of the embodiment of the present application is introduced below.It is first The recipient's node side for first belonging to agricultural product ownership recipient from block chain is introduced.

Such as, referring to Fig. 3, it illustrates a kind of signals of the process of agricultural product information maintaining method one embodiment of the application The method of figure, the present embodiment is applied to recipient's node above-mentioned, and this method may include steps of:

S301 obtains the intelligent contract for constraining commodities trading.

Wherein, intelligent contract is a kind of computer protocol for being intended to propagate, verify or execute in a manner of information-based contract.Intelligence Energy contract permission carries out credible transaction in no third-party situation, these transaction are traceable and irreversible.

In the present embodiment, the signing side of the intelligence contract is that agricultural product ownership recipient and agricultural product ownership turn Shifting side.Therefore, intelligent contract can be ultimately generated and be determined based on interacting between recipient's node and transfer side's node.Accordingly , in the embodiment of the present application, obtain the intelligence contract can be acquisition by recipient's node and transfer side's node it is final Determining intelligent contract.

The intelligence contract, which at least records, to be had: the identification information of the agricultural product of ownership to be transferred, the associated agriculture of the agricultural product The identification information of product information, the identification information of agricultural product ownership recipient and agricultural product ownership transfer side.

Wherein, the agricultural product of the ownership to be transferred can be transferred to another enterprise side from an enterprise side for needs A collection of agricultural product.

Wherein, the identification information of the agricultural product is used for the unique identification agricultural product.

Optionally, in the embodiment of the present application, for the ease of supervising to agricultural product, supervision can be passed through by monitoring party Fang Jiedian is that agricultural product distribute two-dimensional barcode information for identifying the agricultural product in advance.

The associated agricultural product information of the agricultural product may include: the attribute information of agricultural product and the quality letter of agricultural product Breath.

Wherein, the attribute information of agricultural product may include plantation side's information of agricultural product, for example, planting the kind of the agricultural product Plant the company information of enterprise；It can also include the information such as the place of production, the planting environment of the agricultural product, certainly, the attribute of the agricultural product The relevant informations such as the effect of information can also include agricultural product, nutritive value.

The quality condition of the agricultural product may include the credit rating etc. of agricultural product.

Certainly, the particular content which is included can also have other possibility, without restriction herein.

The identification information of agricultural product ownership recipient is used for unique identification agricultural product ownership recipient.Such as, agriculture Product ownership recipient is farm produce sale company, then the identification information can be the company name of the farm produce sale company The unique identifications such as title, trade mark.Optionally, it is contemplated that each node can be respectively node affiliated unit distribution block in block chain Public key in chain, therefore, the identification information of agricultural product ownership recipient can be the public affairs of agricultural product ownership recipient Key.

Correspondingly, the identification information of the agricultural product ownership transfer side is used for the unique identification agricultural product ownership transfer Side.Such as, which can be the information such as Business Name, trade mark or public key.

It is understood that intelligent contract is used for some related constraint information in clear agricultural product ownership transfer, because This, in order to be produced in agricultural product ownership recipient and agricultural product ownership transfer side there are dispute when dispute, can be specified Raw responsible party, which, which also records, has for constraining the agricultural product ownership recipient and the agricultural product ownership transfer The permission regulation of side.Such as, which provides to may include punitive measures and articles of law of promise breaking etc..

Optionally, in order to guarantee to sign intelligent contract both sides identity reality and reliability, intelligent contract Also carry the signature of agricultural product ownership recipient and the signature of the agricultural product ownership transfer side.Wherein, agricultural product The signature of ownership recipient is that the private key using the agricultural product ownership recipient in block chain generates；The agricultural product institute The have the right signature of the side of transfer is to be generated using private key of the agricultural product ownership transfer side in the block chain.

Wherein, the private key of agricultural product ownership recipient and agricultural product ownership transfer side is that the agricultural product ownership connects It is this two side point by the monitoring party node of monitoring party when block chain is added in the node of debit and the agricultural product ownership transfer side The private key not distributed.Carrying out signature by private key can be forged to avoid signature, to guarantee the reliability and authenticity of signature.

S302 sends the upload request of the intelligence contract to the block chain, to remove recipient's node in block chain After being verified with other nodes except transfer side's node to the intelligence contract, the intelligence is stored in the block chain and is closed About.

Wherein, which stores the intelligence contract into block chain for requesting.

In the embodiment of the present application, intelligent contract needs to formulate intelligence conjunction in block chain before storing to block chain Other nodes except node about verify the intelligence contract, to guarantee that the information truth recorded in intelligent contract is effective Property, and advantageously ensure that agricultural product quality.

Correspondingly, recipient's node can only into block chain except recipient's node and transfer side's node its His node sends the upload request.Certainly, which can also send the upload request by all nodes into block chain, But after transfer side's node receives the upload request, then it not will do it respective handling.

Wherein, for recipient's node in block chain and any one node except transfer side's node, the section Point stores intelligence in the block chain and closes in response to the upload request of the intelligent contract after being verified to intelligent contract About.

Specifically, verification tip can be exported after receiving the upload request for uploading the intelligence contract in the node, with Prompt user verifies the intelligence contract.Such as, enterprise side or monitoring party belonging to node can be in the intelligence contracts Agricultural product information and quality are verified, and verification result is uploaded in node, so that node obtains verification result.

In view of each node is the storing data into block chain based on common recognition mechanism in block chain.Therefore, in this Shen Please be in embodiment, node can store the intelligence into the block chain based on common recognition mechanism after being verified to the intelligence contract It can contract.

It in the embodiment of the present application, can for recipient's node in block chain and other nodes except transfer side's node To carry out common recognition verifying to intelligent contract, if confirmation is verified the quantity or ratio of this node in other all nodes Example is more than preset threshold, then other all nodes are reached common understanding, to can make every other node that can also store the intelligence Contract.

In the present embodiment, common recognition verifying can be with are as follows: using the common recognition verifying of ballot.Specifically, each node is right After intelligent contract verifying, the node can send ballot instruction, the throwing to other nodes except the node if the verification passes Ticket instruction is verified intelligent contract for characterizing the node.Correspondingly, if the quantity for the ballot instruction that node receives Ratio with node total number amount is more than preset threshold, then it is assumed that is verified, on this basis, each node in block chain is equal The intelligence contract can be stored.

Optionally, if other nodes in for block chain except recipient's node and transfer side's node are based on altogether Knowledge mechanism confirms that the intelligence contract is verified in underproof situation, and the monitoring party node in the block chain is tested in the intelligent contract of confirmation It demonstrate,proves in underproof situation, can also indicate that monitoring party carries out case study to the intelligence contract, so that monitoring party node can be with The analysis of monitoring party input is obtained as a result, and uploading to analysis result in block chain.

Wherein, which can be is detected by the quality of the intelligence contract and agricultural product, from the agricultural production In all participants involved by product ownership transfer, determine that there are the sides of breaking one's promise of non-honest behavior, and will the side of breaking one's promise with And the non-honest behavior of the side of breaking one's promise uploads in block chain.

It should be noted that the embodiment of the present application is to be asked with recipient's node to the upload that block chain sends the intelligence contract Illustrate for asking, but it is understood that, due to all having the intelligence contract in recipient's node and transfer side's node, because This, in the embodiment of the present application, is also possible to transfer side's node and sends the upload request for uploading the intelligence contract to the block chain. In that case, the treatment process of block chain interior joint is similar, specifically may refer to the introduction of step S302, no longer superfluous herein It states.

S303, confirmation agricultural product it is up-to-standard after, send contract to the block chain and come into force instruction.

Wherein, contract is sent to block chain come into force indicate to be actually each node transmission contract life into block chain Effect instruction.

Wherein, which, which comes into force, indicates that the node being used to indicate in the block chain makes a living the state setting of the intelligence contract Effect state, and the ownership transfers of the agricultural product is recorded to the recipient.

It is understood that when intelligent contract uploads to block chain, the intelligence contract and Pending The Entry Into Force, only in the agricultural production Product ownership recipient it is qualified to the quality verifications of agricultural product and indicate recipient's node agricultural product it is up-to-standard after, this connects Debit's node just confirms that the intelligence contract comes into force, while confirming the reception agricultural product, realizes being transferred to for agricultural product ownership The recipient of the agricultural product ownership.

Correspondingly, block chain interior joint is also used to, comes into force after instruction, stored for recording the agriculture receiving the contract The ownership of product is recorded by the ownership transfer that the agricultural product ownership transfer side is transferred to agricultural product ownership recipient. Such as, agricultural product M ownership is transferred to enterprise B from enterprise A, then ownership transfer record will record: agricultural product M: enterprise A is transferred to Enterprise B.Therefore, it is recorded by inquiring the transfer of the available ownership to agricultural product of block chain.

It is understood that being received when the ownership of each agricultural product shifts it can be seen from the embodiment of the present application Recipient's node of the agricultural product ownership all can be by intelligent contract involved during this ownership transfer and institute Transinformation of having the right is stored into block chain.In this way, can store in block chain involved by each ownership transfer of agricultural product Information, thus by inquiry block chain it is available to the quality of the agricultural product of links, institute during Circulation of Agricultural Products It has the right recipient etc. relevant information.

As it can be seen that in the embodiment of the present application, during agricultural product ownership transfer occurs, belonging to agricultural production in block chain Recipient's node of product ownership recipient can obtain the intelligent contract for constraining commodities trading, and uploading to block chain should Intelligent contract, and other nodes in block chain can just store the intelligence contract after being verified to the intelligence contract, thus So that each node supervises the intelligent contract during agricultural product ownership transfer in block chain, intelligent conjunction ensure that The safety and reliability of the relevant agricultural product information of agricultural product recorded in about.

Moreover, recipient's node can confirm the agricultural product it is up-to-standard after, can just trigger the intelligence contract and come into force, And make the transfering state of the nodes records agricultural product ownership in block chain, to advantageously ensure that the peace of agricultural product quality Full property and reliability are also beneficial to securely and reliably obtain the agricultural product information during Circulation of Agricultural Products by block chain And the related datas such as ownership transfer.

In addition, since the node in block chain is during verifying intelligent contract, alsos relate to treat and turn The verifying for moving the quality of the agricultural product of ownership, can just upload intelligent contract, to be further ensured that only after being verified The safety and reliability of agricultural product quality.

It is understood that determination leads to agricultural production in time in order in the case where there is the underproof situation of agricultural product quality The underproof responsible party of quality, recipient's node determine the agricultural product it is off quality in the case where, the recipient Node can also send the instruction off quality for being directed to the agricultural product to the monitoring party node in block chain.The quality does not conform to Lattice instruction is used to indicate the quality of the agricultural product of the ownership to be transferred through disqualified upon inspection.

Correspondingly, the monitoring party node can turn in response to the instruction off quality from the ownership for participating in the agricultural product In the multiple participants moved, determine that there are the sides of breaking one's promise of non-honest behavior, and the non-honest of the side of breaking one's promise is stored into block chain Record.

Wherein, multiple participant includes at least the agricultural product ownership recipient and agricultural product ownership transfer side.It can With understanding, during Circulation of Agricultural Products, the agricultural product ownership recipient of different links and agricultural product ownership transfer Side is all different.Therefore, if deposited between the agricultural product ownership recipient in some part and agricultural product ownership transfer side In non-honest behavior, cause agricultural product quality undesirable, then subsequent agricultural product ownership occurs in transfer process, next The agricultural product ownership recipient of link also will detect that agricultural product quality is unqualified, and in that case, there are non-honest rows For the side of breaking one's promise be possible to agricultural product ownership recipient and agricultural product institute not necessarily in this ownership transfer link Have the right the side of transfer.

Such as, referring to fig. 4, it illustrates a kind of a kind of processes of agricultural product information maintenance system of the application to interact schematic diagram, The present embodiment may include steps of:

Recipient's node of S401, agricultural product ownership recipient are obtained for constraining agricultural product ownership recipient and agriculture The intelligent contract of commodities trading between product ownership transfer side.

The intelligence contract can recorde the identification information of agricultural product to be transferred, e.g., the two-dimensional barcode information of agricultural product；Also It can recorde the relevant agricultural product information of the agricultural product such as the attribute information of the agricultural product, quality information of agricultural product.Meanwhile it should Intelligent contract also records the mark letter of the identification information and agricultural product ownership transfer side that have agricultural product ownership recipient Breath.

Certainly, which can be with quality between agricultural product ownership recipient and agricultural product ownership transfer side Constraint rule utilizes the signature for the agricultural product ownership recipient that the private key of agricultural product ownership recipient generates, Yi Jili With the signature etc. for the agricultural product ownership transfer side that the private key of the agricultural product ownership transfer side generates.It specifically may refer to front The related introduction of embodiment, details are not described herein.

S402, recipient's node send the upload request for uploading the intelligence contract to block chain.

S403, node in block chain in addition to recipient's node and sender's node in response to the upload request, After being verified to the intelligence contract, belongs in the storage region of block chain in the node and store the intelligence contract.

Wherein, the operation of step S402 and step S403 may refer to the related introduction of preceding embodiment, herein no longer It repeats.

S404, recipient's node obtains the quality verification of the agricultural product of ownership to be transferred as a result, if quality verification knot Fruit characterizes the up-to-standard of the agricultural product, thens follow the steps S405；If not, thening follow the steps S407.

Wherein, the quality verification result that recipient's node obtains can be passed through by agricultural product ownership recipient to agricultural production The quality of product tests to determine, specific implementation process the application is without restriction.Wherein, which can be with table Levy agricultural product quality it is whether qualified, either, characterize the agricultural product quality whether with require or retouch in the intelligence contract The uniform quality etc. stated.

It is understood that confirming the up-to-standard of the agricultural product in recipient's node, then the confirmation of recipient's node is to agriculture The quality verification of product passes through, and in that case, then can trigger intelligent contract and come into force, and complete the ownership of the agricultural product Transfer.

, whereas if recipient's node confirms the off quality of the agricultural product, then recipient's node will not then touch It sends out intelligent contract to come into force, be damaged to avoid to agricultural product ownership recipient.In that case.Recipient's node The instruction off quality to the monitoring party node feeding back of monitoring party is needed, also so that finally determination leads to quality to monitoring party node Underproof concrete reason, and determine to cause responsible party off quality.

S405, recipient's node confirm agricultural product it is up-to-standard in the case where, each node hair into the block chain Contract is sent to come into force instruction.

S406, node in block chain come into force instruction receiving the contract, the state setting of the intelligence contract are made a living Effect state, and store in the storage region for belonging to block chain for recording the ownership of the agricultural product by the agricultural product ownership Transfer side is transferred to the ownership transfer record of agricultural product ownership recipient.

It is understood that recipient's node confirm agricultural product it is up-to-standard in the case where, recipient's node Also active states can be set by the intelligence contract recorded in the storage region for belonging to block chain in itself, and records the agricultural production The ownership of product is transferred to agricultural product ownership recipient from the agricultural product ownership transfer side.
