Technical & Operational Comparison
ZK-Proof Gating vs. Traditional Methods
A detailed comparison of implementing access control for on-chain assets or functions using StarkNet's ZK-Proof Gating versus conventional Web2 and Web3 approaches.
| Feature | Traditional Web2 Auth | On-Chain Role-Based | Chainscore ZK-Proof Gating |
|---|---|---|---|
Privacy & Data Leakage | High (centralized database) | Medium (public on-chain roles) | None (proofs reveal zero user data) |
Gas Cost for Verification | N/A | High (on-chain logic execution) | Ultra-low (off-chain proof, on-chain verify) |
Time to Implement | 2-4 weeks | 3-6 weeks | 2-4 weeks (with our SDK) |
Security Model | Centralized server trust | Smart contract risk | Cryptographic (STARK) security |
User Experience (UX) | Passwords/2FA | Wallet pop-ups, gas fees | Single-click, gasless verification |
Compliance (KYC/AML) | Manual, intrusive checks | Impossible without doxxing | Selective, privacy-preserving attestations |
Scalability (TPS) | High (depends on infra) | Low (limited by L1/L2) | High (batched verification) |
Audit & Maintenance Burden | Your team's responsibility | Your team's responsibility | Fully managed by Chainscore |
Typical Implementation Cost | $50K - $150K+ | $80K - $200K+ | From $25K (development + 1 year support) |

Frequently Asked Questions
Common questions from technical leaders evaluating our StarkNet-based access control solutions.
Standard implementations take 3-6 weeks from kickoff to mainnet deployment. This includes requirements analysis, smart contract development, Cairo integration, testing, and audit preparation. Complex integrations with existing DeFi protocols or custom logic can extend to 8-10 weeks. We provide a detailed project plan within the first week.
