Each node 101 may receive input information and maintain shared data (i.e., blockchains) within the blockchain network based on the received input information while operating normally. In order To ensure information intercommunication in the blockchain network, each node may have information connection, and any two nodes may implement Peer-To-Peer (P2P) communication, and specifically may perform P2P communication through a wired communication link or a wireless communication link. For example, when any node in the blockchain network receives input information, other nodes acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network are consistent.
The client 20 and the tax office server 30 may access the blockchain network and may communicate with nodes in the blockchain network, such as initiating service requests to the nodes, obtaining data from the nodes, and so forth. The client 20 may also communicate with the tax office server 30, where the client 20 may specifically be a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle-mounted intelligent terminal, and the like, and the embodiment of the present invention is not limited thereto.
It should be noted that the number of nodes shown in fig. 1a is only illustrative, and any number of nodes may be deployed according to actual needs, and the client 20 and the tax office server 30 may communicate with the same node in the blockchain network or communicate with different nodes in the blockchain network respectively.
Each node in the blockchain network has a corresponding node identifier, and each node in the blockchain network can store node identifiers of other nodes in the blockchain network, so that the generated block can be broadcast to other nodes in the blockchain network according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an Internet Protocol (IP) address or any other information that can be used to identify the node, and the table is described by taking the IP address as an example.
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |
| Node N | 119.123.789.258 |
Each node in the blockchain network stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 1b, the block chain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.
When each block in the block chain is generated, referring to fig. 1c, when a node where the block chain is located receives input information, the input information is verified, after the verification is completed, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the block chain network where the newly generated blocks are located according to the node identifications of the other nodes in the block chain network, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.
The intelligent contract can be operated on the nodes of the block chain network, the intelligent contract is realized by codes executed when a certain condition is met, developers can define contract logic through a programming language, issue the contract logic to the block chain (intelligent contract registration), and call keys or other events to trigger execution according to the logic of contract terms to complete the contract logic and simultaneously provide the functions of upgrading and cancelling the intelligent contract.
In some possible embodiments, a node 101 of the block chain network may obtain a bill validation request submitted by the client 20 or the tax authority server 30 for the first bill, where the bill validation request carries a characteristic value (e.g., a hash value) of the transaction information corresponding to the first bill, and the node 101 queries, from the block chain, bill information related to the characteristic value of the transaction information corresponding to the first bill to obtain a query result of the first bill, generates a validation result for the first bill according to the query result, and sends the validation result of the first bill to the client, where the validation result indicates authenticity of the first bill and/or tax payment conditions (including completed tax payment or incomplete tax payment) of the first bill, so that the bill can be validated conveniently through the block chain and accuracy of the query result is effectively ensured.
In some possible embodiments, when acquiring a bill validation request for a first bill, a node 101 of the blockchain network may query, on one hand, bill information related to a feature value of transaction information corresponding to the first bill from the blockchain to obtain a first query result, and on the other hand, may broadcast the bill validation request to other nodes 101 in the plurality of nodes included in the blockchain network 10, so that the other nodes 101 also query the first bill, that is, query, from the blockchain, bill information related to the feature value of the transaction information corresponding to the first bill to obtain a second query result, so that the node 101 uses the first query result of itself and the second query result of the other nodes 101 together as query results for the first bill, and can further improve the reliability in bill validation by combining the query results of the plurality of nodes, and ensuring the validity of the verification result.
