Why Custom Optimization Matters
Optimized vs. Generic ZK Circuit Development
A direct comparison between generic, off-the-shelf ZK circuits and the performance-optimized, EVM-compatible circuits we develop for production applications.
| Development Factor | Generic / In-House Build | Chainscore Optimized |
|---|---|---|
Time to Production | 4-6 months | 6-10 weeks |
Circuit Size (Gates) | 1M+ (unoptimized) | 200K-500K (optimized) |
Proving Time (Local) | 30-60 seconds | 2-5 seconds |
EVM Gas Cost per Verification | 800K - 1.2M gas | 250K - 450K gas |
Custom Constraint Support | Limited / None | Full (Tailored to your logic) |
Security Audit & Review | Your responsibility | Included (2 rounds) |
Ongoing Optimization | Manual, costly updates | Managed service (SLA available) |
Total First-Year Cost | $180K+ (Team + Tools) | $75K - $150K (Fixed Scope) |

PROVEN METHODOLOGY
Our Optimization Process
Our systematic approach to ZK circuit optimization delivers measurable improvements in performance and cost, moving your project from concept to production with predictable results.
01
Circuit Architecture Review
We analyze your existing circuit design for inefficiencies in constraint systems, gate composition, and proof generation logic. This initial audit identifies the highest-impact optimization targets, typically reducing verification costs by 30-50%.

02
Constraint System Optimization
We refactor and minimize your R1CS or Plonkish arithmetization to reduce the total number of constraints. This directly translates to faster proof generation and lower on-chain verification gas costs for your dApp users.
