DropKick is a proposed minimal commit/reveal rescue protocol for Bitcoin designed to protect 'quantum procrastinators' — users who haven't migrated to post-quantum-safe wallets before Q-day. The protocol leverages knowledge asymmetries (e.g., BIP32 xprivs, taproot internal keys, hashed address preimages) that honest users possess but quantum attackers cannot compute. DropKick combines merkle-tree aggregated commitments, Simple Commitment Verification (SCV), delayed reveal (hundreds to thousands of blocks), key certification via a PQ signing key, and salvage fees to incentivize aggregators. Compared to SNARK-based approaches, DropKick is simpler, faster to verify, and requires no heavy cryptographic machinery. Compared to LifeBoat, it trades tight miner-censorship resistance for simpler indexing, cheaper commitments, and broader KA generality. The protocol requires a two-step online process (commit then reveal after a delay) and a proportional fee to miners to disincentivize censorship attacks.
