In the following, description will be given of specific implementation scenarios provided in connection with fig. 1b, fig. 1c, and fig. 1d, where the data sharing system shown in fig. 1b is a data sharing system, and the data sharing system 100 refers to a system for performing data sharing between nodes, where the data sharing system may include a plurality of nodes 101, and the plurality of nodes 101 may be respective clients in the data sharing system. Each node 101 may receive input information while operating normally and maintain shared data within the data sharing system based on the received input information. In order to ensure the information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and the nodes can transmit information through the information connection. For example, when any node in the data sharing system receives input information, other nodes in the data sharing system acquire the input information according to a consensus algorithm, and store the input information as data in the shared data, so that the data stored on all nodes in the data sharing system are consistent.
Each node in the data sharing system has a node identifier corresponding to the node identifier, and each node in the data sharing system can store the node identifiers of other nodes in the data sharing system, so that the generated block can be broadcast to other nodes in the data sharing system according to the node identifiers of other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol interconnected between networks) address and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.
Table 1 correspondence between node names and node identifications
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 data sharing system stores one and the same blockchain. The block chain consists of a plurality of blocks, referring to fig. 1c, the block chain consists 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 time stamp and a difficulty value, the block main body stores input information, the next block of the starting block takes the starting block as a father 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, the version number, the time stamp and the difficulty value of the father block, and the like, so that the block data stored in each block in the block chain are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.
When each block in the blockchain is generated, referring to fig. 1d, when the node where the blockchain is located receives input information, checking the input information, after the checking is completed, storing the input information into a memory pool, and updating a hash tree used for recording the input information, and then updating an update timestamp to be the time when the input information is received, and trying different random numbers to calculate 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
The SHA-256 is a eigenvalue algorithm used for calculating eigenvalues, version is version information of related block protocols in a block chain, prev_hash is a block head eigenvalue of a parent block of a current block, merkle _root is an eigenvalue of input information, ntime is update time of an update timestamp, nbits is current difficulty, is a fixed value in a period of time and is determined again after exceeding a fixed period of time, x is a random number, and TARGET is an eigenvalue threshold, wherein the eigenvalue threshold can be determined according to nbits.
Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the blockchain is located sends the newly generated blocks to other nodes in the data sharing system where the newly generated blocks are located according to the node identification of other nodes in the data sharing system, the other nodes verify the newly generated blocks, and the newly generated blocks are added into the blockchain stored in the newly generated blocks after the verification is completed.
