It should be noted that the number of nodes shown in fig. 1a is merely illustrative, and any number of nodes may be deployed according to actual needs.
Each node in the blockchain network has a node identifier corresponding to the node identifier, and each node in the blockchain network can store the node identifiers of other nodes in the blockchain network, so that the generated blocks can be broadcast to other nodes in the blockchain network according to the node identifiers of the 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 internet protocol (Internet Protocol, IP) address, or any other information that can be used to identify the node, and the table is described only by way of example as an IP address.
Node name Node identification
Node 1 117.114.151.174
Node 2 117.116.189.145
… …
Node N 119.123.789.258
Wherein each node in the blockchain network stores one and the same blockchain. The blockchain is composed of a plurality of blocks, see fig. 1b, the blockchain 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 time stamp 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 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 of the father 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 are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
Wherein SHA256 is a eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the 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; TARGET is a eigenvalue threshold that can be determined from 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 blockchain network where the newly generated blocks are located according to the node identifications of other nodes in the blockchain network, 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.
