Dad: Son, what is this again?
Son: Dad, this is just a random, 256-bit hexadecimal number. A bitcoin private key.
A private key is used to spend bitcoin and as the source of its public key. The public key is required to receive bitcoin.
Dad: Are public keys the same thing as addresses?
Son: No. Bitcoin addresses are derived from a public key using a one-way function. Or in other words:
A bitcoin address is a hashed version of a public key. It’s shorter than the original public key.
