The essence of time is to carry on
The essence of space is extension
The law of causation runs through it
Blockchain, one block after another, with one height overlapping and one height closely linked
As time goes:
No one can change what has been written into history
And all the laws of change will be recorded in the next link
Rule is algorithm
Blockchain: different chains open up territory according to their own rules. A piece of land follows a piece of land and is extended endlessly
