The version number of this block is written in the block head of each block.
In a particular application, version number specifically refers to the transaction version for identifying the digital asset block chain that block is recorded
The trading rules of this code name, the digital asset block chain of different editions number are different, need to distinguish transaction rule by version number
Then.
The present embodiment generates multiple blocks and is saved according to chain model by carrying out blocking processing to digital asset,
Without being converted and being recombinated to digital asset data, can direct storing data, data structure is natural, intuitive；Pass through basis
Holding time is sequentially generated unique ID of each block, each block is divided into block head and block body, and in each block
Block head in unique ID, timestamp, cryptographic Hash and address of this block and cryptographic Hash and the address of previous block is written, side
Just it quickly searches and positioning block, included data verification function prevents data to be tampered.
It should be understood that the size of the serial number of each step is not meant that the order of the execution order in above-described embodiment, each process
Execution sequence should be determined by its function and internal logic, the implementation process without coping with the embodiment of the present invention constitutes any limit
It is fixed.
