Core Platform Capabilities We Deliver
We architect and deploy the complete technical foundation for your ZK-verified sensor data marketplace, from secure device onboarding to provable data monetization.
01
ZK-Proof Generation Engine
On-chain verification of sensor data integrity with zero-knowledge proofs. We implement custom circuits (Circom, Halo2) to prove data authenticity, location, and timestamp without exposing raw inputs, enabling trustless marketplace transactions.

Frequently Asked Questions
Common questions from CTOs and product leads about building a ZK-powered sensor data marketplace.
We deliver a production-ready MVP in 4-6 weeks. This includes core marketplace smart contracts, a basic data ingestion pipeline, ZK proof integration for data verification, and a frontend dashboard. Complex integrations (e.g., custom hardware oracles, multi-chain settlement) can extend this to 8-10 weeks. We work in 2-week sprints with clear deliverables.
