Does anyone have a public key that corresponds to a 30-character private key?
sure, here you go
Private key (30 characters): 0123456789abcdef0123456789abcd
Public key associated : 02b17074952d370c7b69ced0290fe82bf92321c9b9d8d7691f6aff716982bf4bc5
I'm looking for something like the Bitcoin Puzzle – an address with a balance, but where the private key is in decimal format and has at most 30 digits.
