P2PKH · reuse-exposed

P2PKH addresses hide the pubkey behind a SHA-256 + RIPEMD-160 hash UNTIL the first outgoing spend, which reveals it in the signature script or witness data. This address has been spent from, so its pubkey is permanently on chain. Every subsequent UTXO at this address is just as exposed as the moment of first spend.

First revealed at block 293,229 on 2014-03-30 (input_spend).
