Re: I found a collision. The hard part is proving it.

If one private key and diffirent address. Can it possible?

Actually its the other way around.

Actually, it depends on what you mean by "address".

There are 2 different P2PKH addresses for every private key (compressed, and uncompressed).

There are 2¹⁶⁰ different P2SH addresses for every private key.

Puplic address key.
I mean that one private key (A) for addresses (AA) and (BB).
where AA and BB compressed.
