In the embodiment of the invention, the blockchain is a decentralized distributed database, and the characteristics of collective maintenance by a plurality of fund transaction participants added to the blockchain are represented. The data blocks are stored in the database in time sequence, a plurality of fund transaction records are stored in each block, and the non-tamper property, the non-forgery property and the verifiability of the data in the block are ensured by using a cryptography method; using a consensus algorithm to enable all nodes (theoretically all nodes) of the whole network to finish approval of the block; and exchanging data between different nodes through Peer-to-Peer (P2P).

As an alternative embodiment, after the reporting node obtains the altered fund transaction data and before the reporting node broadcasts the fund transaction data to the blockchain, the method may include the following steps:
the reporting node judges whether the reporting node has reporting authority for the transaction data type of the fund transaction data; if the reporting node has reporting authority, broadcasting the fund transaction data to a blockchain; if the reporting node does not have reporting authority, the fund transaction data is not broadcast to the blockchain.
202. The verification node receives and verifies the fund transaction data; if the fund transaction data is successfully verified, the verification node broadcasts a notice of the successful verification of the fund transaction data to the blockchain, so that each node in the blockchain records the fund transaction data into each account book maintained after receiving the notice; the verification node is any node except the reporting node in the block chain.
As an alternative embodiment, after the verifying node receives the fund transaction data and before the verifying node verifies the fund transaction data, the method may include the steps of:
the verification node judges whether the verification node has verification authority for the transaction data type of the fund transaction data; if the verification node has verification authority, executing verification of the fund transaction data; if the verification node does not have the verification authority, the fund transaction data is not verified.
In the embodiment of the present invention, optionally, a manner in which each node in the blockchain records the fund transaction data into each maintained ledger after receiving the notification may specifically be:
for any node in the blockchain, the node judges whether the node has recording authority of the transaction data type of the fund transaction data after receiving the notification; if the node has the recording authority, the node records the fund transaction data into an account book maintained by the node; if the node does not have the recording authority, the node does not record the fund transaction data into an account book maintained by the node.
As an optional implementation manner, a plurality of specific fund transaction participants can be selected, and nodes corresponding to the fund transaction participants form a alliance chain; the alliance chain refers to a blockchain with the consensus process controlled by a preselected node, only transaction member nodes belonging to the inside of the alliance have rights to access, when data change occurs to the transaction member nodes forming the alliance chain, the change data is broadcasted to the whole alliance chain, for example, 10 financial institution systems participating in a certain fund transaction project together form the alliance chain.

the node judges whether the alliance chain node identification information/digital certificate information of the node to be verified is matched with the alliance chain node identification information/digital certificate information of the node to be verified;
If the nodes are matched, judging that the node to be verified belongs to the alliance chain node, and executing verification or recording operation on the changed data; if the nodes do not match, the node to be verified is judged not to belong to the alliance chain node, and further processing operation on the modified data is not executed.
Therefore, by implementing an alternative implementation manner, through one alliance chain operated by a plurality of specific fund transaction participants, only authorized nodes in the alliance chain can be ensured to access shared data in the alliance chain, so that the problem of privacy disclosure of the nodes is avoided, and meanwhile, the efficiency of processing the fund transaction is improved.
203. The query node detects a query request; if the query node detects the query request, extracting target fund transaction data queried by the query request from an account book maintained by the query node; the query node is any node in the blockchain.
In the embodiment of the invention, the account book maintained by any node in the blockchain stores the fund transaction data in a connected data block structure. Each data block includes a block header and a block body, the block body stores a plurality of fund transaction data records and a binary merck tree formed by hash values of each record, and the block header generally includes a version number, a hash value (hash pointer) of a previous data block connected with the data block, and the like. The block header/body data item and block chain structure (e.g., single-chain and double-chain structure) may also vary according to the application requirements.
As an alternative embodiment, the query request may include a hash value and an index number of the target fund transaction data. The query node extracts the target fund transaction data queried by the query request from the account book maintained by the query node specifically comprises the following steps:
the query node obtains a hash value and an index number of target fund transaction data included in the query request;

the query node extracts the target fund transaction data corresponding to the index number from the block according to the index number of the target fund transaction data.
Therefore, when implementing the method described in fig. 2, when any node forming the blockchain changes the fund transaction data, the modified fund transaction data is broadcasted to the whole blockchain, so that other nodes in the blockchain can acquire the modified fund transaction data, thereby realizing real-time synchronous sharing of the fund transaction data without occupying excessive labor cost; in addition, the changed fund transaction data can be formally recorded into the account book corresponding to each node on the blockchain after verification and confirmation, so that the credibility of sharing the fund transaction data is improved, and the system is real and reliable.
Referring to fig. 3, fig. 3 is a flowchart illustrating another exemplary blockchain-based fund data sharing method according to an embodiment of the present invention. As shown in fig. 3, the blockchain-based fund data sharing method may include the steps of:
301. the reporting node obtains the changed fund transaction data.
302. The reporting node judges whether the reporting node has reporting authority for the transaction data type of the fund transaction data; if the reporting node has reporting authority, executing the steps 303-305; if the reporting node does not have reporting authority, ending the flow.
303. The reporting node encrypts the fund transaction data by using the stored first encryption parameter corresponding to the transaction data type of the fund transaction data, and broadcasts the encrypted fund transaction data to the blockchain.
304. The verification node receives the encrypted fund transaction data, and decrypts the encrypted fund transaction data by using the stored first decryption parameters so as to judge whether the verification node has verification authority for the transaction data type of the fund transaction data.
305. If the decryption is successful, the verification node determines that the verification node has verification authority, and obtains the decrypted fund transaction data.
In the embodiment of the invention, if the decryption fails, the verification node determines that the verification node does not have the verification authority, and the fund transaction data is not verified.
306. The verification node verifies the fund transaction data; if the verification of the fund transaction data is successful, the verification node encrypts the notice of the successful verification of the fund transaction data by using the stored first encryption parameter, and broadcasts the encrypted notice to the blockchain.
As an alternative implementation, a preset standard is set, and only when the verification result after the verification node in the blockchain verifies the fund transaction data meets the preset standard, the fund transaction data can be issued to the blockchain. Specifically, if the preset standard is a bayer fault tolerance standard, the bayer fault tolerance standard is that the number of verification nodes for successfully verifying the data of the foundation trade is greater than two thirds of the total number of verification nodes. For example, for one account registration data, if the total number of verification nodes is 12 and the number of verification nodes for successfully verifying the account registration data is 9, the verification result of the account registration data satisfies the bayer fault tolerance standard, and the notification for successfully verifying the account registration data may be broadcasted to the blockchain after being encrypted.
307. For any node in the blockchain, after receiving the encrypted notification, the node decrypts the encrypted notification by using the stored second decryption parameter to judge whether the node has recording authority of the transaction data type of the fund transaction data; if the decryption is successful, the node determines that the node has recording authority, obtains decrypted fund transaction data, and records the fund transaction data into an account book maintained by the node; if the decryption fails, the node determines that the node does not have recording authority, and the node does not record the fund transaction data into an account book maintained by the node.
In the embodiment of the invention, the verification/recording authority can be granted to the appointed node aiming at the transaction data types of different fund transaction data. And, each node granted authentication/recording authority for the transaction data type stores encryption/decryption parameters corresponding to the transaction data type. For example, for a piece of user asset data that is newly generated at the completion of a transaction, only the node corresponding to the specified asset registration system can verify the piece of user asset data and issue it onto the blockchain where the node corresponding to the asset registration system is located.
It can be seen that by implementing the embodiment of the invention, the fund transaction data can be sent to the node with verification/recording authority for the transaction data type according to the type of the transaction data type; and by encrypting the fund transaction data, the privacy of the data published on the blockchain can be ensured.
308. The query node detects a query request; if the query node detects the query request, extracting target fund transaction data queried by the query request from an account book maintained by the query node.
Therefore, when implementing the method described in fig. 3, when any node forming the blockchain changes the fund transaction data, the modified fund transaction data is broadcasted to the whole blockchain, so that other nodes in the blockchain can acquire the modified fund transaction data, thereby realizing real-time synchronous sharing of the fund transaction data without occupying excessive labor cost; in addition, the changed fund transaction data can be formally recorded into the account book corresponding to each node on the blockchain after verification and confirmation, so that the credibility of sharing the fund transaction data is improved, and the system is real and reliable; in addition, the fund transaction data can be transmitted to the node with verification/recording authority for the transaction data type according to the type of the transaction data type; and by encrypting the fund transaction data, the privacy of the data published on the blockchain can be ensured.
Referring to fig. 4, fig. 4 is a flowchart illustrating another exemplary blockchain-based fund data sharing method according to an embodiment of the present invention. As shown in fig. 4, the blockchain-based fund data sharing method may include the steps of:
401. the reporting node obtains the changed fund transaction data.
402. The reporting node judges whether the reporting node has reporting authority for the transaction data type of the fund transaction data; if the reporting node has reporting authority, executing the steps 403 to 405; if the reporting node does not have reporting authority, ending the flow.
403. The reporting node encrypts the fund transaction data by using the stored first encryption parameter corresponding to the transaction data type of the fund transaction data, and signs the encrypted fund transaction data by using the node identification of the reporting node.
404. The reporting node broadcasts the encrypted fund transaction data signed by the reporting node to a blockchain.
405. The verification node receives the encrypted and reporting node signed fund transaction data, and identifies the node identification of the reporting node in the encrypted and reporting node signed fund transaction data.
406. The verification node judges whether the reporting node is a trusted reporting node according to the node identification of the reporting node, if so, the stored first decryption parameter is utilized to decrypt the encrypted and signed fund transaction data to judge whether the verification node has verification authority for the transaction data type of the fund transaction data.
407. If the decryption is successful, the verification node determines that the verification node has verification authority, and obtains decrypted fund transaction data.
In the embodiment of the invention, besides limiting the verification/record authority of the nodes in the blockchain to the specific transaction data type through encryption/decryption parameters, the node identification can be used for identifying whether the source node of any fund transaction data is a trusted reporting/verification node.
Specifically, as an optional implementation manner, the mode that the verification node judges whether the reporting node is a trusted reporting node according to the node identifier of the reporting node is specifically as follows:
the verification node judges whether the node identification can be searched in the stored white list according to the node identification of the reporting node; if yes, judging that the reporting node is a trusted reporting node; if not, judging that the reporting node is not the trusted reporting node.
Further, each node in the blockchain stores a paired public key and a secret key in advance, the secret key is used for encrypting the node identifier from plaintext to ciphertext, and the public key is used for decrypting the ciphertext to plaintext, so as to obtain the node identifier, therefore, the manner that the reporting node broadcasts the encrypted and signed fund transaction data to the blockchain can be as follows:
the reporting node encrypts the node identifier by using the stored key to obtain the encrypted node identifier;
the reporting node broadcasts the encrypted node identification and the encrypted and signed fund transaction data to the blockchain.
Correspondingly, the verification node receives the encrypted and reporting node signed fund transaction data, and identifies the node identification of the reporting node in the encrypted and reporting node signed fund transaction data, comprising:
the verification node receives the encrypted node identification and the encrypted and reported node signed fund transaction data, and identifies the node identification of the reported node in the encrypted and reported node signed fund transaction data;
the verification node decrypts the encrypted node identification by using the stored public key, and judges whether the decrypted node identification is consistent with the identified node identification; if the report nodes are consistent, judging whether the report nodes are trusted report nodes according to the node identification of the report nodes.
Thus, the node identification can be prevented from being maliciously tampered, and the integrity of verification information is ensured.
408. The verification node verifies the fund transaction data; if the verification of the fund transaction data is successful, the verification node encrypts the notice of the successful verification of the fund transaction data by using the stored first encryption parameter, and signs the encrypted notice by using the node identification of the verification node.
409. The authentication node broadcasts the encrypted and authenticated node signed notification to the blockchain.
410. For any node in the blockchain, after receiving the notification after encryption and verification node signature, the node identifies the node identification of the verification node in the notification after encryption and verification node signature; the node judges whether the verification node is a trusted verification node according to the node identification of the verification node, if so, the stored second decryption parameters are utilized to decrypt the notification after encryption and signature of the verification node; if the decryption is successful, the node determines that the node has recording authority, obtains decrypted fund transaction data, and records the fund transaction data into an account book maintained by the node; if the decryption fails, the node determines that the node does not have recording authority, and the node does not record the fund transaction data into an account book maintained by the node.
It can be seen that, by implementing the embodiment of the invention, besides defining the verification/recording authority of the node by the data type, the verification/recording authority of the node can be defined by the node type (trust degree), so that the fund transaction data can be directionally issued to the designated node, but the credibility of the fund transaction data is not influenced at the same time.
411. The query node detects a query request; if the query node detects the query request, extracting target fund transaction data queried by the query request from an account book maintained by the query node.
