Embodiment one:
A kind of distribution relation record method based on block chain provided below the embodiment of the present application one is described, and asks
Refering to attached drawing 1, the distribution relation record method based on block chain in the embodiment of the present application one includes:
Step S101, the distribution relation record request that the first user sends is received, the distribution relation record request includes
The signature of the distribution relationship of first user and second user, the signature of first user and the second user；
After the first user and second user establish distribution relationship, the first user can send distribution to management platform
Relation record request, by management platform by the distribution relation record of the first user and second user in block chain.
It may include the signature of the distribution relationship of the first user and second user, the first user in distribution relation record request
With the signature of second user, the distribution relationship of the first user and second user may include distribution relationship between superior and subordinate and distribution commission
Allocation plan, for example, the first user can be second user higher level distribution person, when second user complete transaction after need according to
Distribution commission allocation plan pays commissions to the first user, or can also be the higher level distribution person of the first user with second user.
The signature of first user and the signature of second user are in order to which the authenticity to distribution relationship is verified, and first uses
Family pair distribution relationship relevant to the first user carries out available first cryptographic Hash of Hash operation, and second user pair is used with second
The relevant distribution relationship in family carries out available second cryptographic Hash of Hash operation, and the signature of the first user can be used by the first user
The private key of first user is encrypted to obtain to the first cryptographic Hash, and the signature of second user can use second user by second user
Private key the second cryptographic Hash is encrypted to obtain.
Step S102, the signature of first user is decrypted to obtain the first Kazakhstan using the public key of first user
Uncommon value, is decrypted the signature of the second user to obtain the second cryptographic Hash, to described using the public key of the second user
The distribution relationship of first user and second user carries out Hash operation and obtains third cryptographic Hash, judges first cryptographic Hash and institute
Whether consistent with the third cryptographic Hash state the second cryptographic Hash；
The public key that the first user can be used is decrypted the signature of the first user to obtain the first cryptographic Hash, uses second
The public key of user is decrypted the signature of second user to obtain the second cryptographic Hash, closes to the distribution of the first user and second user
System carries out Hash operation and obtains third cryptographic Hash；
By judging the first cryptographic Hash and whether the second cryptographic Hash is consistent with third cryptographic Hash may determine that distribution relationship
Authenticity.
It step S103, will when first cryptographic Hash and consistent with the third cryptographic Hash second cryptographic Hash
The distribution relationship of first user and second user, first user's signature and second user signature are broadcasted to block
In chain.
Due to if operation content changes, even if amplitude of variation very little, also resulting in last calculating in Hash operation
Cryptographic Hash gap it is very big, therefore, if the first cryptographic Hash and the second cryptographic Hash are consistent with third cryptographic Hash, then it represents that calculate
First cryptographic Hash, the second cryptographic Hash are consistent with the content of third cryptographic Hash；
Meanwhile first the signature of user have passed through the private key encryption of the first user, the signature of second user have passed through second
The private key encryption of user, private key may indicate that the identity of user.
Therefore, when the signature decryption of signature obtained the first cryptographic Hash of decryption of the first user and second user obtain the
When two cryptographic Hash are consistent with third cryptographic Hash, show that the distribution relationship has been checked and approved to the first user and second user,
This distribution relationship is true distribution relationship.
After the authenticity that confirmed the distribution relationship of the first user and second user, management platform is by the first user and the
Distribution relationship, the signature of the first user and the signature of second user of two users, which is broadcasted into block chain, to be stored, and is avoided point
Situations such as pin relationship distorts or loses.
When not consistent with third cryptographic Hash there are any one in the first cryptographic Hash and the second cryptographic Hash, management platform can
Not execute the prompt of any movement or return recording unsuccessfully to the first user.
Further, described when first cryptographic Hash and second cryptographic Hash are consistent with the third cryptographic Hash
When, the distribution relationship of first user and second user, first user's signature and the second user are signed and broadcasted
It is specifically included into block chain:
A1, when first cryptographic Hash and consistent with the third cryptographic Hash second cryptographic Hash, use platform
Public key is signed to the distribution relationship of first user and second user, first user's signature and the second user and is carried out
Encryption；
Since the data on block chain are disclosed to each node, and distribute relationship and belong to for some enterprises and need to protect
Close content is therefore, wide by the signature of the distribution relationship of the first user and second user, the signature of the first user and second user
It casts to before block chain, can first be encrypted using platform public key.
A2, by the distribution relationship of encrypted first user and second user, first user's signature and described
Second user signature broadcast is into block chain.
After having used platform public key to be encrypted, only using platform private key just can to encrypted data deciphering,
I.e. only management platform can check encrypted data, and other block chain nodes can receive the data after being encrypted,
But it can not learn specific content.
Therefore, the distribution relationship of first user and second user, first user's signature and described second are used
Family signature can both guarantee the secure contents such as distribution relationship by block chain using broadcast after platform public key encryption into block chain
Other nodes receive record, and can guarantee that other nodes can not learn the specific details of secure content, avoid information leakage.
Further, the method also includes:
B1, the signature for receiving distribution relational query instruction and third user, using the public key of the third user to described
The signature of third user is verified；
When inquiring user's needs inquiry distribution relationship relevant to third user, the qualification for proving to have inquiry is needed,
So inquiry user needs to send the signature of distribution relational query instruction and third user to managing platform, management platform uses the
The public key of three users verifies the signature of third user.
The signature of third user can specify content to obtain by third user using the private key encryption of third user, specify content
It can be determined according to actual needs, for example, specified content can be distribution relational query instruction, or distribution relationship
Inquiry instruction carries out the 4th cryptographic Hash obtained after Hash operation.
B2, when the signature verification of the third user passes through, from local data base obtain and the third user phase
The distribution relationship is back to inquiry user by the distribution relationship of pass；
When the signature verification of third user passes through, indicate that third user has authorized inquiry user query and third user's phase
The qualification of the distribution relationship of pass, third user and inquiry user can be same or different user at this time, for example, user A
Want to inquire the distribution relationship of oneself, at this time third user and inquiry user all refer to alternative family A, user A need to send oneself
Signature extremely management platform；Alternatively, user A wants to inquire the distribution relationship of user B at this time, third user refers to user B, inquiry at this time
User refers to user A, and user A needs to inquire qualification to user's B application, and user B returns to signature and gives user A, user A that can just lead to
The distribution relationship of the signature inquiry user B of user B is crossed, otherwise user A can not inquire the distribution relationship of user B.
After the signature verification of third user passes through, distribution relevant to third user can be obtained from local data base and closed
Distribution relationship is back to inquiry user by system.
Alternatively, obtaining the encrypted and third from block chain when the signature verification of the third user passes through
The relevant distribution relationship of user is decrypted the distribution relationship using platform private key, and the distribution relationship after decryption is returned
To the inquiry user.
Distribution relationship can also obtain, due to block chain other than can be in local data library inquiry from block chain
The distribution relationship of middle acquisition is encrypted distribution relationship, it is possible to the distribution relationship is decrypted using platform private key,
The distribution relationship after decryption is back to inquiry user again.
If the signature verification of third user fails, any movement can not be executed, or authentication failed can also be returned
Prompt information to inquiring user.
Further, the method also includes:
C1, data base recreation instruction is received, the area for obtaining each node in block chain is instructed according to the data base recreation

D1, data base recreation instruction is received, each node in the block chain is obtained according to data base recreation instruction
Block chain data merkle root；
D2, the corresponding block chain data of merkle root approved using the node for being greater than preset proportion are as standard block chain number
According to the distribution relationship and commission settlement records reconstruction local data base in the standard block chain data.
When carrying out the comparison of block chain data of each node, can directly it be compared using complete block chain data
Compared with, but the data volume for needing operation extremely huge, and arithmetic speed is extremely slow, accordingly it is also possible to be referred to according to data base recreation
The merkle root for obtaining the block chain data of each node in block chain is enabled, the merkle root of each node is compared, with
Greater than the node of preset proportion approve the corresponding block chain data of merkle root as standard block chain data.
The block chain data of each node storage are segmented into multiple affairs, such as using the data of a block as one
Affairs, each affairs can carry out Hash operation and obtain cryptographic Hash, and two neighboring cryptographic Hash can carry out Hash operation and obtain
One layer of cryptographic Hash successively calculates and forms merkle tree, when the block chain data of two nodes storage are consistent, the two nodes
Block chain data formed merkle tree it is identical, root node having the same, i.e. merkle root.
It therefore, is the block chain number that can determine whether each node by comparing the merkle root of the block chain data of each node
According to whether unanimously, the comparison of complete block chain data is become to the comparison of merkle root, the number of operation can be greatly reduced
According to the speed for measuring and improving operation.
