The predetermined consensus algorithm may be a pbft (physical Byzantine Fault probability) algorithm, or a raft (propagation And Fault probability) algorithm, but is not limited thereto. The accuracy of the transaction data can be improved by the consensus process, and the transaction data is hardly possible to be tampered.
In step S102, an invoicing request message is received, and the transaction data is acquired from the block chain according to the invoicing request message.
In one embodiment of the present invention, the billing request information includes at least, but is not limited to, a unit name and a tax identification number. After the terminal computer stores the transaction data in the blockchain, if receiving invoice billing request information of an invoice, triggering to acquire the corresponding transaction data from the blockchain. Specifically, as an example, the transaction data may carry unique identification information, and the invoicing request may include the unique identification information, so as to query and obtain corresponding transaction data from the blockchain according to the unique identification information.

step S201: and performing Hash calculation on the transaction data to obtain a first Hash value, and uplink storing the first Hash value and the transaction data into the block chain.
As an example, a first Hash value is obtained by performing a Hash calculation on the transaction amount, the transaction time and the transaction object information to which the transaction data belongs, and the transaction amount, the transaction time and the transaction object information are linked and stored in the blockchain together with the first Hash value. The specific uplink storing process can be described with reference to the consensus process in the previous embodiment.
Step S202: and after the transaction data are acquired from the block chain according to the billing request information, calculating the acquired transaction data to obtain a second Hash value, and comparing the first Hash value with the second Hash value.
That is, after the transaction data such as the transaction amount, the transaction time and the transaction object information are obtained from the block chain, the obtained transaction amount, the obtained transaction time and the obtained transaction object information are subjected to Hash calculation to obtain a second Hash value, and then the first Hash value and the second Hash value are compared. The specific Hash calculation process can refer to the prior art, and is not described herein again.
Step S203: and when the first Hash value is the same as the second Hash value, generating the preset invoice information according to the invoicing request information and the transaction data. When the first Hash value is the same as the second Hash value, the obtained transaction data is not falsified and is real data, so that preset invoice information can be generated according to the invoicing request information and the transaction data, and then an electronic invoice can be formed.
In the embodiment, the accuracy of the transaction data can be further ensured by calculating and comparing the Hash value of the transaction data through the Hash, so that the non-repudiation of the issued electronic invoice is further improved, the possibility of tampering is reduced, the normal order of financial business transactions is ensured to a certain extent, and the legal rights and interests of property persons are maintained.
