Architectural Comparison
Traditional Audit Log vs. ZKP-Enhanced Audit Trail
A technical breakdown of how legacy logging systems compare to modern, privacy-preserving audit trails powered by Zero-Knowledge Proofs.
| Audit Capability | Traditional Audit Log | ZKP-Enhanced Audit Trail |
|---|---|---|
Data Privacy & Confidentiality | ||
Regulatory Compliance (GDPR, CCPA) | Partial (requires data masking) | Full (data never exposed) |
Proof of Data Integrity | Manual hash verification | Automated ZK validity proof |
Selective Disclosure | Not possible | Granular proof generation |
On-Chain Verifiability | ||
Audit Trail Size | Large (stores all raw data) | Compact (stores only proofs) |
Implementation Complexity | Moderate | High (requires ZK expertise) |
Time to Production-Ready | 2-4 weeks | 6-12 weeks with Chainscore |
Typical Annual Cost (Infra + Dev) | $50K - $200K+ | $120K - $300K (managed service) |

Frequently Asked Questions
Get clear answers on how our ZK-powered audit trail service works, from implementation to long-term support.
Traditional ledgers store transaction details in plain text, exposing sensitive business logic and counterparty information. Our solution uses Zero-Knowledge Proofs to cryptographically verify the correctness of transactions and state transitions without revealing the underlying data. This provides a verifiable, tamper-proof audit trail for regulators or auditors while keeping proprietary strategies and user data confidential. It's a paradigm shift from transparency-by-default to verifiability-without-exposure.
