Bitcoin’s proposed defense against quantum-computing threats is broadening beyond BIP-360 and SHRINCS to include Lifeboat and Dropkick as contingency measures. BIP-360, still in draft form, would introduce P2MR (Pay to Merkle Root) to reduce prolonged public-key exposure and help users protect funds before quantum computers pose a practical cryptographic threat. Blockstream Research’s SHRINCS, a SHA-256-based hash signature scheme, is intended to support the transition to quantum-resistant signatures. The roadmap was outlined in a free X post published on the 15th by Christine D. Kim, who writes the BTCBeforeLight newsletter, and reflects an emerging combination of proposals rather than a completed Bitcoin upgrade.
