From backend upgrades to protocol refinements — this week’s dev update brings another round of performance boosts.
1/
Circuit Performance Optimization
Successfully implemented a significant optimization to reduce circuit complexity by leveraging gnark's hint system. Instead of computing MiMC hash operations directly within the circuit constraints, we now use hints to handle the computation off-circuit while maintaining proper constraint validation. This approach substantially reduces the number of constraints in the circuit, leading to improved proving times and lower memory consumption.
2/
Polyhedra i-D Integration Refinement
- Completed the integration of the circuit optimization into the full Polyhedra i-D verification workflow. Key accomplishments include:
- Streamlined the proving pipeline to incorporate the hint-based MiMC optimization
- Validated the multi-level recursion structure to ensure end-to-end soundness
- Cleaned up the codebase, removing redundant proving steps and consolidating the recursive verification layers
The system now maintains cryptographic soundness while operating more efficiently across all recursion levels.
Stay tuned for more updates.
