Node name Node identification
Node 1 117.114.151.174
Node 2 117.116.189.145
… …
Node N 119.123.789.258

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
Wherein SHA-256 is a eigenvalue algorithm used for calculating 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; 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.
