How Much Possible Address In Bitcon Blockchain?

[crismass1225]

As i understand... There will be no possible same address in bitcoin blockchain count how many letters and numbers in one address and count every units of it, it takes million of combination or even a billion of combination...

millions? billion? it's a 25-34 (IIRC) long almost alphanumeric case sensitive combination, just to keep the maths simple, if you had only 10 combinations per character slot (and in reality you have plenty more), then you'd be looking at a number of combinations ending with 34 zeroes, or thereabouts. think that, but considerably larger.

plus, it's not really a big issue, as addresses are use-once, any incredibly unlikely collision wouldn't be particularly damaging.
