Healthcare ZK Marketplace Integration FAQs
Common questions from CTOs and product leads evaluating zero-knowledge marketplace solutions for sensitive healthcare data.
A production-ready MVP with core marketplace features (data listing, ZK-proof generation, and secure settlement) typically deploys in 4-6 weeks. This includes smart contract development, integration with your existing data systems, and frontend implementation. Complex integrations with legacy EHRs or custom ZK-circuits can extend this to 8-10 weeks.
