Frequently Asked Questions
Clear answers to common questions about implementing blockchain for KYC and identity verification.
A traditional database is a single point of failure; if breached, all data is exposed. A blockchain distributes data across a network in an encrypted, tamper-proof manner. It uses cryptographic principles to ensure that data, once written, cannot be altered or deleted, and access can be tightly controlled, providing a much higher level of security and auditability.
Absolutely. In fact, blockchain can enhance GDPR compliance. By implementing concepts like Self-Sovereign Identity (SSI) and Zero-Knowledge Proofs, users retain control of their data and can provide consent for its use on a granular level. We design our systems to respect the "right to be forgotten" and ensure data minimization principles are followed.
The timeline varies based on complexity. A Proof of Concept (PoC) can often be developed in 6-8 weeks. A full production-grade implementation with legacy system integration typically takes 4-6 months. Our agile process ensures we deliver value incrementally and keep the project on a clear timeline.
ROI is multi-faceted. Financially, clients typically see significant savings from reduced manual review costs, lower fraud losses, and avoidance of regulatory fines. Strategically, the ROI comes from faster customer onboarding, higher conversion rates, improved customer trust, and creating a significant competitive advantage.
