PROVEN PROCESS
Our Delivery Methodology
We deliver production-ready ZK attestation infrastructure through a structured, milestone-driven process designed for technical founders. Our methodology ensures predictable delivery, clear communication, and secure, auditable outcomes.
01
Architecture & Protocol Design
We begin with a technical deep-dive to design a custom ZK circuit architecture and attestation protocol tailored to your DePIN's data model and consensus requirements. This includes selecting optimal proving systems (e.g., Plonk, Groth16) and defining the trust model.

Frequently Asked Questions
Get clear answers on how our ZK-powered attestation service integrates with your DePIN project, from technical specs to security and pricing.
Our ZK Attestation Interface is a developer-first API and SDK that allows your DePIN's physical hardware (sensors, devices, nodes) to generate cryptographically verifiable proofs of real-world data and work. It converts raw device data into zero-knowledge proofs (ZKPs) that can be verified on-chain without revealing the underlying data. This enables trustless, automated rewards distribution, secure oracle feeds, and fraud-resistant reputation systems for your network.
