What are the chances of anyone accidentally creating the same Bitcoin address? Is it remotely possible or there is some kind of checks before network, software, God or something would do a check first before approving the Bitcoin address. Again, I'm just thinking out loud. Hmmm...🤔
It is extremely unlikely that two identical Bitcoin addresses will be created accidentally. This is because Bitcoin addresses are generated by a cryptographic hash function, which transforms the input into a unique, pseudo-random string of fixed-length characters.
The probability that two different inputs produce the same hash output is extremely low, almost negligible. However, while the probability is extremely low, it is not technically impossible for two identical Bitcoin addresses to be created accidentally. But the probability is so low that the possibility of such an occurrence is generally regarded as insignificant.
Anyway , a similar question had already been asked
