The embodiment of the invention provides a specific implementation mode of a financial product transaction share determination method based on a block chain, and referring to fig. 1, the method specifically comprises the following steps:
step 100: the first node sends a share transaction request to the service node.
It is understood that the first node is a client node, and the first node in step 100 may also send the share transaction request in a group manner, specifically: the client node group initiates share transaction application of fund and financing, and transmits application data of share transaction to the block chain network; in addition, the client node may also obtain query transaction information from acknowledgement data that the share transaction was received in the blockchain network.
Step 200: and the mining node carries out validity verification on the share transaction request according to a consensus algorithm.
Specifically, the mining node (mining node group) performs a validity check on the share transaction request through some kind of consensus mechanism (which may be PoW, PoS, etc.), adds a new transaction block to the blockchain, and transmits the block to all nodes of the network at the same time. Wherein the validity check of the transaction block is typically a validity check of the transaction block signature.
Step 300: the service node sends the share transaction request to a second user according to a validity verification result so as to complete share transaction, wherein the share transaction request comprises: an identification, an input array, and an output array.
When the share transaction request passes the validity verification in step 200, it is sent to the second user. It will be appreciated that each share transaction request (transfer of transaction share information between nodes) consists of three parts: the method comprises the steps of identification, input array and output array, and in addition, in order to clarify different transaction service scenes, a transaction service type field and a transaction content field can be added, so that a certain transaction record can be conveniently and quickly searched, and the whole block chain does not need to be traversed.
As can be seen from the foregoing description, in the method for determining transaction shares of financial products based on blockchains according to an embodiment of the present invention, a first node sends a share transaction request to a service node; then, the mining node carries out validity verification on the share transaction request according to a consensus algorithm; and finally, the service node sends the share transaction request to a second user according to a validity verification result so as to complete share transaction, wherein the share transaction request comprises: an identification, an input array, and an output array. The invention adopts the block chain technology, and embeds the characteristics of decentralized block chain, tamper resistance, openness and transparency and the like into the transaction share confirmation and control process of financial products, thereby realizing the beneficial effects of data security, efficient and traceable transaction, transparent transaction, supervised transaction and the like.
In one embodiment, referring to fig. 2, the method for determining transaction shares of financial products based on blockchains further comprises:
step 400: the first node encrypts the share transaction request according to a pre-generated key.
Step 500: and the mining node, the service node and the second node decrypt the share transaction request according to the public key corresponding to the secret key.
Step 600: the first node generates the key using a symmetric encryption algorithm.
A symmetric encryption algorithm (also called private key encryption) refers to an encryption algorithm that uses the same key for encryption and decryption. Sometimes called traditional cryptographic algorithm, the encryption key can be derived from the decryption key, and the decryption key can also be derived from the encryption key. Requiring the sender and receiver to agree on a key before securely communicating. The security of symmetric algorithms depends on the key.
In one embodiment, referring to fig. 3, step 300 further comprises:
step 301: when the result of the validity verification is legal, the service node root sends the share transaction request to the second user; and
step 302: the service node registers the share transaction request and broadcasts it into the blockchain.
Specifically, the unused Transaction Share Output (UTXSO) is a number locked with the Share owner's Public Key (PK), and in fact is a number encrypted using the owner's public key, which can only be unlocked by the owner's private key (SK). When the share transaction of the financial products is carried out, a user uses the UTXSO of the user and generates a new UTXSO, the UTXSO needs to be locked by using a Public Key (PK) of a receiver, each node has a public and private key pair (SK, PK) of the user, wherein the SK is a private key, and the PK is a public key.
In one embodiment, the share transaction consists of an interface field of the financial product.
The interface field records user share transaction data in detail, different transaction share contents can be generated in a configurable manner according to different transaction service types, and a data encryption mode can be set according to customer requirements, generally a symmetric encryption algorithm such as DES (data encryption standard) and AES (advanced encryption standard) can be set.
As can be seen from the foregoing description, in the method for determining transaction shares of financial products based on blockchains according to an embodiment of the present invention, a first node sends a share transaction request to a service node; then, the mining node carries out validity verification on the share transaction request according to a consensus algorithm; and finally, the service node sends the share transaction request to a second user according to a validity verification result so as to complete share transaction, wherein the share transaction request comprises: an identification, an input array, and an output array. The invention comprehensively uses the block chain core technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, improves the traditional transaction share confirmation method of the financial products, and provides a safe, efficient and traceable transaction share determination method by taking block transactions as carriers.
To further illustrate the present solution, the present invention provides a specific application example of the block chain-based financial product transaction share determination method, which specifically includes the following contents.

The unused Transaction Share Output (UTXSO) is a number that is locked with the Share owner's Public Key (PK), and in fact is a number encrypted using the owner's public key, and can only be unlocked by the owner's private key (SK). When carrying out fund share transaction, a user uses own UTXSO and generates a new UTXSO, the UTXSO needs to be locked by using a Public Key (PK) of a receiver, each node has own public and private key pair (SK, PK) in the invention, wherein SK is a private key, and PK is a public key. This embodiment provides four types of block link points for financial transaction share confirmation: the client node, the service node, the mining node and the supervision node are described in detail as follows:

Wherein the validity check of the transaction block is typically a validity check of the transaction block signature.
And a supervision node D: the system has the main functions of receiving and checking the authority of all transaction data in the block chain network, analyzing and processing the transaction data, displaying illegal nodes in the whole network, limiting the transaction authority of the illegal nodes, ensuring the legality of fund and financial transaction and ensuring the safety and transparency of a financial market.
Fig. 5 shows a block transaction format suitable for the financial product transaction share confirmation method.

In the scene, the circulation of transaction share data among all nodes is communicated through block transaction (Tx), so that not only can the data isolated chain be effectively eliminated, but also the efficiency of transaction share confirmation can be improved. All nodes involved in FIG. 6 have a unique public and private key pair, where the public and private keys of client node A are (SK)A,PKA) The public and private key of the service node B is (SK)B,PKB) The public and private keys of the mining node C are (SK)C,PKC) The public and private keys of the supervision node D are (SK)M,PKM). In the invention, the data interaction between nodes is divided into two data flow processing directions of sending transaction data and receiving transaction data, and the detailed description is given by taking the example from the transaction of share application initiated by a client to the transaction of share confirmation received.
