Technical and Strategic FAQs
Get clear, technical answers to the most common questions CTOs and engineering leads ask when evaluating a DAS ZK Circuit development partner.
A complete, production-ready DAS ZK circuit system typically takes 6-10 weeks from specification to audit-ready delivery. This includes 2 weeks for architecture & spec finalization, 3-5 weeks for core circuit development and integration, and 1-2 weeks for internal testing and documentation. Complexities like custom polynomial commitments or novel fraud-proof mechanisms can extend this timeline, which we scope and price upfront.
