Flow chart, in the figure, it is assumed that relevant between every two manufacturer, that is, vendor A is relevant with manufacturer B and manufacturer C, factory
Quotient B is relevant with vendor A and manufacturer D, and manufacturer C is relevant with vendor A and manufacturer D, vendor A and manufacturer D onrelevant.
Step 601, manufacturer generates the electronic contract between the manufacturer and up-and down-stream vendors as transaction record.
In this step, both sides' title of transaction, such as vendor A and manufacturer B be may include in the transaction record；Wound
Build the promoter of transaction record, for example, vendor A；Target of transaction, such as iron and steel raw material, steel ingot etc. further include Object of Transaction
Price, loco, complete a business transaction the contents such as mode, the above content is identical as the content in electronic contract.Wherein, for example,
The upstream manufacturer of manufacturer B is vendor A, and downstream manufacturers are manufacturer D；The upstream manufacturer of manufacturer C is vendor A, and downstream manufacturers are manufacturer
D；Vendor A does not have upstream manufacturer, and downstream manufacturers include manufacturer B and manufacturer C；D upstream manufacturer, manufacturer includes manufacturer B and manufacturer C, is not had
There are downstream manufacturers.
In this example, the transaction record between vendor A creation and manufacturer B, is denoted as transaction record AB；Manufacturer C is created in factory
Transaction record between quotient D is denoted as transaction record CD.
Step 602, the relationship between the manufacturer is sent to management server, to establish authority checking table.
In this step, management server establishes authority checking table according to the relationship between manufacturer, wherein being stored with manufacturer
Whether the relationship of contacting between manufacturer, i.e. manufacturer and its up-and down-stream vendors, the authority checking table can for recording manufacturer
The relationship of transaction record between manufacturer is inquired, the manufacturer in upstream-downstream relationship can inquire relative transaction record, but
Be cannot inquire the transaction record unrelated with its, such as vendor A cannot inquire the record manufacturer B created by manufacturer B and manufacturer D it
Between transaction record, manufacturer B can inquire by vendor A creation record vendor A and manufacturer B between transaction record.
In this step, respective private key is also sent to management server by each manufacturer, so that management server can root
It is decrypted according to the transaction record that above-mentioned authority checking table is stored into block chain to different vendor.Private key is sent out by each manufacturer
The time for giving management server can be any time, might not carry out in this step.
Step 603, manufacturer adds the transaction record that it is created using respective public key by respective block chain node
It is close.
In this step, vendor A encrypts transaction record AB using its public key Ka, forms encrypted transaction record
Ka (AB), manufacturer C encrypt transaction record CD using its public key Kc, form encrypted transaction record Kc (CD).Wherein,
Transaction record Ka (AB) further includes the information of a part of unencryption or also has a transaction note teaching except secret transaction record
Header file is recorded, Noncoded Information or transaction record header file include at least both parties, create the transaction record manufacturer, may be used also
To include the information such as target, the date of transaction.
In the embodiment of the present application, due to being in specific cooperation in production relationship, all participants are all a spies
Determine the ring in cooperation in production relationship, therefore each participant will access the cooperation in production using the block chain node of oneself
Block chain network, the corresponding block chain node of manufacturer can take as same side, such as vendor A i.e. block chain node
A, manufacturer B i.e. block chain node B.
Step 604, by respective block chain node, the encrypted transaction created using respective private key to it is remembered for manufacturer
Record is signed.
In this step, vendor A signs to transaction record Ka (AB) with its private key PKa, the transaction after forming signature
It records PKa (Ka (AB))；Manufacturer C signs to transaction record Kc (CD) using its private key PKc, the transaction note after forming signature
It records PKc (Kc (CD)).Wherein, signature can a part only to encrypted transaction record sign, such as to transaction remember
Record header file is signed, the transaction after the transaction record of the encryption of signature with transaction record header file and thereafter to be constituted to signature
Record will either for before the transaction file of encryption or the character string of rear 5% (or other percentages) is signed
Signature constitutes the transaction record after signature with transaction record header file and the transaction record of encryption.
Step 605, the transaction record after signature is broadcast in block chain network by manufacturer, to pass through common recognition verifying.
In this step, the transaction record PKa (Ka (AB)) that vendor A is created on block chain node A is broadcast to it
On its block chain node B/C/D, these block chain nodes carry out common recognition verifying to the encryption transaction record, that is, utilize factory
The public key of quotient A carries out sign test to the signature of PKa (Ka (AB)), the public key decryptions of vendor A is signed, and will be in the signature after decryption
Hold, for example, transaction record header file perhaps transaction record preceding 5% with the transaction record header file (plaintext) that receives or friendship
Preceding 5% easily recorded compares, if unanimously, proving that the transaction record is the transaction for being sent, and being encrypted by vendor A
It is recorded as being tampered.
Step 606, block chain node will be in the account book of transaction record write-in block chain.
In this step, after through common recognition verifying, transaction that each node in block chain broadcasts block chain node A
In the account book for recording Ka (AB) write-in block chain.It wherein, include that the part of encryption and unencryption are used in the transaction record
The part of inquiry, content is the abstract of transaction record in this section, does not include the detailed content of transaction.
It is illustrated in figure 7 a kind of Transaction Information inquiry of cooperative system for producing based on block chain network of the embodiment of the present invention
Flow chart, management server judges whether to be able to access that detailed transaction record according to the permission of issuer in detail in this figure, enhancing
