The first embodiment is as follows:
referring to fig. 1, a distribution relationship recording method based on a block chain according to a first embodiment of the present application is described below, where the distribution relationship recording method based on a block chain according to the first embodiment of the present application includes:
step S101, receiving a distribution relation record request sent by a first user, wherein the distribution relation record request comprises the distribution relation between the first user and a second user, the signature of the first user and the signature of the second user;
after the first user establishes a distribution relationship with the second user, the first user may send a distribution relationship recording request to the management platform, and record the distribution relationship of the first user and the second user in the blockchain through the management platform.
The distribution relationship record request may include the distribution relationship between the first user and the second user, the signature of the first user, and the signature of the second user, and the distribution relationship between the first user and the second user may include a distribution superior-superior relationship and a distribution commission allocation scheme.
The signature of the first user and the signature of the second user are used for verifying the authenticity of the distribution relationship, the first user performs hash operation on the distribution relationship related to the first user to obtain a first hash value, the second user performs hash operation on the distribution relationship related to the second user to obtain a second hash value, the signature of the first user can be obtained by encrypting the first hash value by the first user through a private key of the first user, and the signature of the second user can be obtained by encrypting the second hash value by the second user through a private key of the second user.
Step S102, decrypting the signature of the first user by using the public key of the first user to obtain a first hash value, decrypting the signature of the second user by using the public key of the second user to obtain a second hash value, performing hash operation on the distribution relationship between the first user and the second user to obtain a third hash value, and judging whether the first hash value and the second hash value are consistent with the third hash value;
the public key of the first user can be used for decrypting the signature of the first user to obtain a first hash value, the public key of the second user is used for decrypting the signature of the second user to obtain a second hash value, and the distribution relationship between the first user and the second user is subjected to hash operation to obtain a third hash value;
the authenticity of the distribution relationship can be judged by judging whether the first hash value and the second hash value are consistent with the third hash value.
Step S103, when the first hash value and the second hash value are both consistent with the third hash value, broadcasting the distribution relationship between the first user and the second user, the first user signature and the second user signature into a blockchain.
In the hash operation, if the operation content changes, even if the change amplitude is small, the difference distance of the hash value calculated last is very large, so that if the first hash value and the second hash value are consistent with the third hash value, the calculation of the first hash value, the second hash value and the third hash value is consistent;
meanwhile, the signature of the first user is encrypted by the private key of the first user, the signature of the second user is encrypted by the private key of the second user, and the private key can indicate the identity of the user.
Therefore, when the first hash value obtained by decrypting the signature of the first user and the second hash value obtained by decrypting the signature of the second user are both consistent with the third hash value, it indicates that both the first user and the second user have viewed and recognized the distribution relationship, and the distribution relationship is a real distribution relationship.
After the authenticity of the distribution relationship between the first user and the second user is confirmed, the management platform broadcasts the distribution relationship between the first user and the second user, the signature of the first user and the signature of the second user to the blockchain for storage, and the situations that the distribution relationship is tampered or lost and the like are avoided.
When any one of the first hash value and the second hash value is not consistent with the third hash value, the management platform may not perform any action, or return a prompt indicating that the recording fails to the first user.
Further, when both the first hash value and the second hash value are consistent with the third hash value, broadcasting the distribution relationship between the first user and the second user, the first user signature, and the second user signature into the blockchain specifically includes:
a1, when the first hash value and the second hash value are consistent with the third hash value, encrypting the distribution relationship between the first user and the second user, the first user signature and the second user signature by using a platform public key;
since the data on the blockchain is disclosed to each node, and the distribution relationship belongs to the content needing to be kept secret for some enterprises, the distribution relationship between the first user and the second user, the signature of the first user and the signature of the second user can be encrypted by using the platform public key before being broadcast to the blockchain.
A2, broadcasting the encrypted distribution relationship between the first user and the second user, the first user signature and the second user signature into a blockchain.
After the platform public key is used for encryption, only the platform private key is used for decrypting the encrypted data, namely, only the management platform can check the encrypted data, and other block chain nodes can receive the encrypted data but cannot know specific content.
Therefore, the distribution relationship between the first user and the second user, the first user signature and the second user signature are encrypted by using the platform public key and then broadcast to the blockchain, so that not only can the confidential contents such as the distribution relationship be ensured to be received and recorded by other nodes of the blockchain, but also the other nodes can be ensured not to know the specific details of the confidential contents, and information leakage is avoided.
Further, the method further comprises:
b1, receiving a distribution relation query instruction and a signature of a third user, and verifying the signature of the third user by using a public key of the third user;
when the inquiry user needs to inquire the distribution relation related to the third user, the inquiry qualification needs to be proved, so that the inquiry user needs to send a distribution relation inquiry instruction and the signature of the third user to the management platform, and the management platform verifies the signature of the third user by using the public key of the third user.
The signature of the third user may be obtained by encrypting, by the third user, the specified content by using the private key of the third user, and the specified content may be determined according to actual needs, for example, the specified content may be a distribution relation query instruction, and may also be a fourth hash value obtained by performing hash operation on the distribution relation query instruction.
B2, when the signature of the third user passes the verification, acquiring the distribution relation related to the third user from the local database, and returning the distribution relation to the inquiry user;
when the signature of the third user passes verification, the third user indicates that the third user has granted the inquiry user the qualification of inquiring about the distribution relationship related to the third user, at this time, the third user and the inquiry user may be the same or different users, for example, user a wants to inquire about his distribution relationship, at this time, the third user and the inquiry user both refer to user a, and user a needs to send his signature to the management platform; or at this time, the user a wants to query the distribution relationship of the user B, the third user refers to the user B, the querying user refers to the user a, the user a needs to apply for the querying qualification to the user B, the user B returns the signature to the user a, the user a can query the distribution relationship of the user B through the signature of the user B, otherwise, the user a cannot query the distribution relationship of the user B.
After the signature verification of the third user is passed, the distribution relationship related to the third user can be obtained from the local database, and the distribution relationship is returned to the inquiring user.
Or when the signature of the third user passes the verification, obtaining the encrypted distribution relation related to the third user from the blockchain, decrypting the distribution relation by using a platform private key, and returning the decrypted distribution relation to the inquiring user.
The distribution relationship can be inquired in the local database and also can be acquired from the blockchain, and because the distribution relationship acquired in the blockchain is the encrypted distribution relationship, the distribution relationship can be decrypted by using the platform private key and then returned to the inquiring user.
If the third user fails to verify the signature, no action may be performed, or a prompt may be returned to the querying user indicating that the verification failed.
Further, the method further comprises:
and C1, receiving a database rebuilding instruction, acquiring the blockchain data of each node in the blockchain according to the database rebuilding instruction, taking the blockchain data approved by the nodes with the ratio larger than the preset ratio as standard blockchain data, and rebuilding the local database according to the distribution relationship in the standard blockchain data.
When the local database is damaged or a worker considers that data updating and reconstruction are needed to be carried out on the local database, a database reconstruction instruction can be sent, and the management platform acquires block chain data of each node in the block chain according to the database reconstruction instruction;
after the blockchain data of each node in the blockchain is acquired, the blockchain data approved by the nodes with the ratio greater than the preset ratio can be used as standard blockchain data, and the local database is reconstructed according to the distribution relation in the standard blockchain data.
The preset proportion can be set according to actual conditions, and can be set to be 50% for example.
Further, the receiving a database rebuilding instruction, obtaining the blockchain data of each node in the blockchain according to the database rebuilding instruction, and rebuilding the local database by using the distribution relationship in the standard blockchain data, where the blockchain data approved by the nodes greater than a preset ratio is used as standard blockchain data, specifically includes:
d1, receiving a database reconstruction instruction, and acquiring a merkle root of the block chain data of each node in the block chain according to the database reconstruction instruction;
and D2, using the blockchain data corresponding to the merkle root approved by the nodes with the ratio larger than the preset ratio as standard blockchain data, and rebuilding the local database by using the distribution relation and commission settlement records in the standard blockchain data.
When comparing the blockchain data of each node, the complete blockchain data can be directly used for comparison, but the calculation is extremely large in data amount and extremely slow, so that the merkle root of the blockchain data of each node in the blockchain can be obtained according to the database reconstruction instruction, the merkle roots of each node can be compared, and the blockchain data corresponding to the merkle root approved by the node with the ratio larger than the preset ratio can be used as the standard blockchain data.
The blockchain data stored by each node can be divided into a plurality of transactions, for example, data of one block is used as one transaction, each transaction can be subjected to hash operation to obtain a hash value, two adjacent hash values can be subjected to hash operation to obtain a hash value of a previous layer, a merkle tree is formed by calculating layer by layer, and when the blockchain data stored by two nodes are consistent, the merkle trees formed by the blockchain data of the two nodes are the same and have the same root node, namely, the merkle root.
Therefore, whether the blockchain data of each node are consistent or not can be judged by comparing the merkle roots of the blockchain data of each node, and the comparison of the complete blockchain data is changed into the comparison of the merkle roots, so that the data amount of the operation can be greatly reduced, and the operation speed can be improved.
In the distribution relationship recording method based on the blockchain provided by this embodiment, the distribution relationship between the first user and the second user is recorded through the blockchain, so that the situation that the distribution relationship is tampered or damaged and lost can be avoided.
Before data such as distribution relations are broadcasted to the blockchain, the platform public key can be used for encryption, only the management platform can use the platform private key for decryption and checking, and leakage of confidential contents is avoided.
When the inquiry user inquires the distribution relation of a third user, the signature of the third user is verified to judge whether the inquiry user has the inquiry qualification, and the distribution relation can be inquired only if the inquiry user has the qualification.
When the local database is damaged or needs to be updated and rebuilt due to other reasons, the block chain data of each node in the block chain can be obtained through the database rebuilding instruction, the block chain data approved by the nodes with the ratio larger than the preset ratio is used as standard block chain data, the local database is rebuilt according to the distribution relation in the standard block chain data, and the comparison process of the block chain data of each node can be compared through a merkle root, so that the data amount of operation is reduced, and the operation speed is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
