P2PKH (Pay-to-Public-Key-Hash)
Classic Bitcoin address style that commits to a hash of the public key until spend—better exposure timing than P2PK, still classical signatures.
Definition
P2PKH locks value to HASH160(pubkey). The raw public key is typically revealed when spending. That delays key visibility compared with P2PK but does not make the signature scheme post-quantum.
Address reuse after spend removes the benefit: new funds arrive to a key the network has already seen.
