Technical & Commercial Insights
zkML Data Marketplace Development FAQs
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a zkML data marketplace build.
Our standard engagement follows a structured 6-8 week delivery cycle, broken into clear phases:
- Week 1-2: Discovery & Architecture - We define data schemas, ZK circuit logic (using Circom or Halo2), and smart contract architecture.
- Week 3-5: Core Development - Parallel development of verifiable compute circuits, marketplace smart contracts (Solidity/Rust), and the frontend interface.
- Week 6-8: Integration, Testing & Audit - We integrate components, conduct rigorous testing (including proof generation/verification), and perform an internal security audit before deployment.
For complex customizations (e.g., custom consensus for data validation), timelines extend proportionally, which we scope and quote upfront.
