The server generates a new block based on the transaction data and the new version number and chains the new block.
For example, the new chunk includes a chunk header including the local chunk hash value, parent chunk hash value, mercker root, timestamp, transaction identification, version number, and target difficulty, and a chunk, which may include transaction data. The parent block hash value is the hash value of the last block of the new block. The timestamp is the time at which the new chunk was generated. The target difficulty is the number of M which is 0 before the hash value of the new block is calculated, and M is set according to actual needs. The hash value of the transaction data in the block of zones may be calculated as the mercker root. The block hash value can be obtained by calculating the hash value of the parent block hash value, the Mercker root number, the timestamp, the transaction identifier, the version number and the first M bits of the target difficulty, wherein the first M bits are 0.
