Quantum exposure Reuse-exposed

P2SH · reuse-exposed

P2SH 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 954,308 on 2026-06-18 (p2sh_nested_p2wsh_reveal).
