A Technical Comparison for CTOs
ZK Identity vs. Traditional Compliance Methods
Evaluate the architectural and operational trade-offs between building a custom ZK-based identity layer versus using traditional KYC/AML vendors for your Web3 application.
| Compliance Factor | Traditional KYC/AML Vendor | Custom ZK Identity Solution |
|---|---|---|
Data Privacy & Sovereignty | User data stored on vendor servers, high breach risk | User data remains on-chain or with user; proofs only are verified |
Regulatory Flexibility | Pre-defined rules, slow to adapt to new jurisdictions | Programmable logic via smart contracts, adaptable in days |
Integration Complexity | Heavy API integration, often requires centralized backend | Lightweight SDK for on-chain verification; decentralized by design |
Time to Initial Compliance | 4-8 weeks for vendor onboarding & integration | 2-4 weeks for protocol development and audit |
Ongoing Cost Structure | Per-user fees ($1-$5), recurring annual contracts | Primarily gas costs for proof verification; predictable, usage-based |
Audit Trail & Transparency | Opaque, proprietary systems; reports provided periodically | Fully transparent, immutable on-chain record of compliance events |
User Experience Friction | High: Document upload, manual review, wait times | Low: One-time proof generation, instant verification for future actions |
Technical Ownership & Risk | Vendor lock-in, dependency on third-party uptime/API | You control the protocol logic and security model |
Scalability for High-Volume dApps | API rate limits, scaling costs increase linearly with users | Verification scales with underlying blockchain; minimal marginal cost |

PREDICTABLE, TRANSPARENT DELIVERY
Our Delivery Process: From Audit to Integration
A structured, milestone-driven approach to ensure your ZK-powered compliance solution is delivered on time, on budget, and to the highest security standards.
01
1. Compliance & Technical Audit
We conduct a deep-dive analysis of your current KYC/AML workflows and technical stack. We identify regulatory touchpoints and architect a ZK-proof strategy to minimize data exposure while meeting jurisdictional requirements.

2. Architecture & Proof Design
Our cryptographers design custom ZK circuits (using Circom or Noir) to prove compliance assertions (e.g., age > 18, jurisdiction whitelist) without revealing underlying user data. We define the on-chain verifier and off-chain prover architecture.

ZK Identity Solutions
Frequently Asked Questions
Get clear answers on how our ZK-powered identity infrastructure enables regulatory compliance for DeFi, exchanges, and Web3 applications.
Our ZK Identity solution allows users to prove they are verified and not on sanctions lists without revealing their personal data. A user completes KYC once with a trusted provider. We then issue a zero-knowledge proof credential. Your dApp can verify this proof on-chain to ensure regulatory compliance, maintaining user privacy and meeting FATF Travel Rule and other AML requirements. This eliminates the need to store or process sensitive PII on your servers.
