SHRINCS-L. On-Liquid Performance Report
We have designed and benchmarked a version of SHRINCS optimized for Liquid (the signature verifier is written on Simplicity). It has the same building blocks as an original SHRINCS, but trades the signature size for the number of hash operations required to verify the signature. For comparison, Simplicity verifiers for different signature instances:
- SLH-DSA: ~770,000 kWU
- SHRINCS: ~222,000 kWU (stateless)
- SHRINCS-L: ~92,500 kWU (stateless) and ~37,800+ kWU (stateful)
The specification and parameters for an initial and -L versions can be found here.
