Infrastructure Decision Matrix
ZK-KYC vs. Traditional KYC for Prediction Markets
A technical comparison of identity verification approaches for compliant, high-stakes prediction platforms. Evaluate based on user experience, compliance burden, and technical overhead.
| Feature | Traditional KYC | ZK-KYC (Chainscore) |
|---|---|---|
User Onboarding Friction | High (Document upload, manual review) | Low (One-time verification, reusable attestation) |
User Privacy & Data Exposure | High (Sensitive PII stored centrally) | Zero-Knowledge (Only proof of validity) |
Regulatory Compliance | Manual, jurisdiction-specific | Programmable, automated rule enforcement |
Integration Complexity | High (API calls, data handling) | Low (On-chain proof verification) |
Time to First Trade | 24-72 hours | < 5 minutes |
Ongoing AML Monitoring | Batch processing, high latency | Real-time, on-chain compliance checks |
Developer Overhead | High (Build & maintain compliance logic) | Managed Service (We handle the stack) |
Annual Compliance Cost (Est.) | $100K+ in labor & tools | $25K-$75K managed service |
Attack Surface for User Data | Large (Centralized database target) | Minimal (No centralized PII store) |
Scalability for Global Users | Complex (Jurisdictional fragmentation) | Simplified (Unified verification layer) |

A PROVEN FRAMEWORK
Our Implementation Process: From Audit to Integration
We deliver production-ready, privacy-preserving identity attestation systems through a structured, transparent process designed for technical teams. This ensures security, compliance, and seamless integration into your existing stack.
01
1. Architecture & Protocol Audit
We conduct a deep technical review of your existing identity logic and data flows. Our team maps your requirements to optimal zero-knowledge proof frameworks (e.g., Circom, Noir) and on-chain verification patterns, ensuring a scalable and secure foundation.

Frequently Asked Questions on ZK-KYC Implementation
Get clear answers on timelines, costs, and technical specifics for integrating privacy-preserving identity verification into your application.
A standard integration takes 3-6 weeks from kickoff to production. This includes requirements analysis, circuit design, smart contract development, and security audits. For a pre-built module with minimal customization, deployment can be as fast as 2 weeks. Complex, multi-jurisdictional systems with custom credential schemas may take 8+ weeks.
