Optimized stateful hash-based signatures can offer better trade-offs than the standard schemes available today. SHRINCS is live on the @Liquid Network in production today via Simplicity. Jonas Nick at OPNEXT on why this may allow Bitcoin to operate in a post-quantum world without betting on specific future software. Full technical writeup:

OP_CHECKSHRINCS: A Hash-Based Signature Opcode for Post-Quantum Bitcoin

OP_CHECKSHRINCS is a proposed Bitcoin opcode for post-quantum signatures whose security rests on SHA-256, the hash function Bitcoin already uses.

There is no concrete post-quantum signature scheme for Bitcoin today. But over the last year Blockstream Research has been working on exactly this. Director Jonas Nick lays out the proposal: OP_CHECKSHRINCS, a hash-based signature opcode for post-quantum Bitcoin. SHRINCS reaches up to 3 TPS on the compact path. 580-byte signatures from a dedicated signing device. A stateless fallback always available. Already demonstrated on the @Liquid Network . The C++ implementation, Simplicity verifier, and draft spec are all on GitHub.
