The user end 1, the accounting end 2 and the bookkeeping end 3 are respectively connected with the block chain system 4 through a block chain network 5.
In the present embodiment, the block chain system 4 includes block link points that are gradually increased in a chain-generating manner, and the block link points are connected in a chain manner. The blockchain nodes are used for issuing related information of interaction of the user side 1, the accounting side 2 and the accounting side 3 and data information of each adjacent node in at least one target adjacent node to a blockchain network. The data information includes key information and address information.
In this embodiment, the blockchain network node includes: the system comprises a user node, an accounting node, a bookkeeping node, a response node and an information identification node.
The user end 1, the accounting end 2 and the accounting end 3 perform information interaction on the blockchain system 4 through the blockchain network 5, wherein the user nodes transmit data information of the server nodes through the blockchain network 5. The response node is used for feeding back information sent to the user node by the accounting node; the information identification node is used for converting the information of the user node and the accounting node, so that the user terminal 1 and the accounting terminal 3 can identify the information of each other.
In this embodiment, each user terminal 1 registers its own account on the blockchain system 4 to generate a corresponding user node, and the accounting terminal 2 and the billing terminal 3 also have accounts and nodes on the blockchain system 4. By setting the response node and the information identification node, the block chain system 4 can facilitate data interaction between the user side 1 and the accounting side 3 without privately performing corresponding information response and identification, improve data response and transmission speed, reduce performance requirements on hardware equipment, and improve expansibility of the scheme.
As an example of this embodiment, the blockchain system 4 further includes a blockchain underlying platform. The block chain bottom platform is any one of a platform adopting a Hyperlegger block chain technology or an Ethengfang block chain bottom platform.
As an example of this embodiment, the platform using the hyperlegger blockchain technology may be, but is not limited to, a hyper ledger technology platform that opens a source for the Linux foundation.
Accordingly, in the structure of the billing system of this embodiment, referring to the block chain-based billing method shown in fig. 2, the method includes the following steps:
step 201: the user side initiates a registration request to the accounting side, so that the accounting side generates a first private key of the user side on the block chain system according to the registration request, and generates a first public key and a query address according to the first private key.
In this embodiment, a user side initiates a registration request to a billing end, and after receiving the request, the billing end generates a first private key according to a random algorithm and generates a first public key from the first private key according to an elliptic algorithm; when generating the query address, the first public key is embedded into the query address.
In more detail, the accounting terminal 3 randomly selects 256 digits and selects a random entropy source according to the SHA256 algorithm for the selected data. If the first private key is made to display 64-bit numbers, a hexadecimal mark is adopted, and if the first private key is made to display the private key by using bitcoin, a dumpprivkey mark is adopted. And generating a first public key by the first private key according to the following formula: k ═ K × G. Where K is the private key, G is a discrete constant point, and K is the public key. Finally, a query address required by a user side is formed according to the public key, wherein the query address A is RIPEMD160(SHA256(K)), K is the public key, and the query address A is formed into a 20-byte address through Base 58.
Step 202: and the user side receives the first private key and the query address fed back by the accounting side, encrypts the data information according to the first private key to obtain first document data, and writes the first document data into the block chain system through the block chain network.
In this embodiment, step 202 specifically includes:
the method comprises the steps that a user side converts bill data information to be input into electronic information, and the electronic information is encrypted through a first random code;
the user side encrypts the first random code according to the first private key;
and the user side writes the encrypted first document data and the encrypted first random code into the block chain system through the block chain network.
In this embodiment, the first random code is generated by the user side, encrypted by the first private key, and then distributed on the blockchain.
In this embodiment, the data to be entered may include, but is not limited to: financial and newspaper data, invoice data, and the like.
In this embodiment, in step 202, the encryption method using the first private key is an asymmetric encryption method.
Step 203: and the accounting end receives the first public key sent by the accounting end, calls the first document data on the block chain system according to the first public key, and carries out electronic signature on the first document data after the first document data is verified and verified to obtain first accounting data.
In this embodiment, the accounting end receives the first public key sent by the accounting end, and queries the corresponding user end according to the first public key, so as to call the encrypted first document data and the encrypted first random code on the block chain. The accounting terminal decrypts the encrypted first random code according to the first public key to obtain a first random code, and decrypts the encrypted first document data according to the obtained first random code to obtain first document data.
And after the accounting end receives the verification and verification instruction, accounting signature is carried out on the first document data to obtain first accounting data. The accounting signature is an electronic signature, the accounting end can account for the first document data and electronically sign the data after accounting to form first accounting data.
Step 204: and the accounting terminal encrypts the first bookkeeping data according to the first public key and then issues the encrypted first bookkeeping data to the block chain system.
In this embodiment, the encryption manner in step 204 is asymmetric encryption, and may be decrypted by a first private key corresponding to the first public key.
In this embodiment, after the accounting end succeeds in accounting and issues the accounting result to the blockchain system, the blockchain system sends a notification message to the user end to inform the user end of the accounting progress. The first accounting data may be, but is not limited to, placed on the query address or an address corresponding to the accounting end, so that the user end can query the first accounting data conveniently.
Step 205: and the user side inquires the encrypted accounting data corresponding to the user side on the block chain system according to the inquiry address, decrypts the added accounting data according to the first private key, and acquires the account book data corresponding to the user side.
In this embodiment, the book data may include, but is not limited to, the first billing data of the current billing and the historical billing data. The user side can inquire all the accounting data of the user side.
