Private key and Address Private key is 32-byte number.

Address (Hash) is 20-byte number.

Is it true that there is many Private keys that have the same 20-byte hash?

P.S. How to get Address from Private key:

Private key (32-byte number, random) --1--> 04+Public key (64-byte number, elliptic curve point) --2--> Hash, Address (20-byte number) --3--> Address string (Base58 string).


Elliptic curve point multiplication
SHA256, ripemd160
Hex converts to Base58
Yes, that is true.

However, to go from an address to any corresponding private key still requires an unfeasibly large amount of computing.
