Questions tagged [address]
This tag should be used for Bitcoin addresses. A Bitcoin address is an encoding of the hash of an ECDSA public key or a script. Knowledge of this value allows a user to send Bitcoins to another person over the network. Bitcoin addresses begin with a '1', '3', or 'bc1'. Not to be confused with mailing addresses or IP addresses.
