Why Build Native ZK Circuits Into Your AppChain
Native ZK circuits are not just an add-on; they are a foundational component for AppChains demanding privacy, scalability, and verifiable computation. We design circuits that are deeply integrated with your chain's consensus and state model.
01
End-to-End Privacy & Compliance
Implement selective data disclosure for regulatory compliance (e.g., travel rule) and confidential transactions without moving data off-chain. Our circuits enable private state transitions verifiable by your validators.

Native Scalability & Lower Costs
Offload complex computations (like batch DEX settlements or game logic) into a ZK-proof, reducing on-chain gas costs by 70-90% and increasing your chain's transaction throughput significantly.

Custom Virtual Machine Integration
Go beyond generic zkEVMs. We fabricate circuits for your AppChain's custom VM or opcodes, enabling verifiable execution of proprietary business logic that generic rollups cannot support.

04
Enhanced Security & Auditability
Every state change is cryptographically verified. Our circuits are built with formal verification methodologies and undergo rigorous audits (e.g., by Spearbit) before integration, providing a stronger security guarantee than traditional execution.

Sovereign Data & Interoperability
Generate portable proofs of your chain's state that can be verified on Ethereum, other L2s, or partner chains. This enables trust-minimized bridges and interoperability without relying on third-party attestation.

Technical & Commercial Comparison
Native Fabrication vs. Generic ZK Layers
A detailed breakdown of the key differences between our custom, application-specific ZK circuit fabrication and off-the-shelf, generic ZK layers. This comparison highlights the trade-offs in performance, cost, and long-term viability for production-grade Web3 applications.
| Key Factor | Generic ZK Layer (Off-the-Shelf) | Chainscore Native Fabrication |
|---|---|---|
Circuit Optimization | One-size-fits-all logic; bloated constraints | Tailored to your app's exact state transitions |
Prover Performance | 10-100x slower due to generic overhead | Optimized for speed; 2-10x faster proving |
Proof Size | Larger (5-50 KB), higher on-chain costs | Minimal (1-10 KB), reduces gas fees by 60-90% |
Development Time | 2-4 weeks for integration | 4-8 weeks for full design, audit & deployment |
Initial Cost | $0 - $50K (license/subscription) | $75K - $250K (custom development) |
Long-Term TCO (3 Years) | High (ongoing fees, scaling limits) | Lower (one-time build, predictable scaling) |
Security Audit | Shared responsibility; limited customization | Dedicated, full-circuit audit before mainnet |
Protocol Flexibility | Locked into layer's upgrade cycle & features | Full ownership; upgrade on your roadmap |
Best For | MVPs, hackathons, non-critical features | Production DEXs, gaming, enterprise settlement |
