PROVEN METHODOLOGY
Our Structured Optimization Process
A systematic, four-phase approach to deliver measurable improvements in circuit performance, security, and cost-efficiency. We focus on concrete outcomes, not just theoretical gains.
01
Architecture & Bottleneck Analysis
We conduct a deep technical audit of your existing ZK circuit design to identify critical performance bottlenecks and architectural inefficiencies. This includes analyzing constraint system complexity, memory usage patterns, and prover/verifier resource allocation.

Constraint System Optimization
Our experts refactor and streamline your R1CS or Plonkish arithmetization. We apply advanced techniques like custom gate design, lookup argument integration, and non-native field operation reduction to minimize constraint count and improve proving time.
