Since when does the blockchain begin?
has since there been a digital transaction that involved several people with a complex set of codes?
I do not think so.!
The digital currency exchange system has actually been practiced since ancient times.
When a currency has not been used,
Early humans did a barter system.
And when technology has become more sophisticated,
humans continue to implement a barter system in the market.
does this have a basis?
I don't know.
because this is just my simple thoughts.
