🌑 Built on Midnight · PREPROD

Confidential AI Inference. Zero Exposure.

Submit sensitive medical and legal queries to verified AI models on the Midnight blockchain. Your data stays encrypted end-to-end — every result is cryptographically proven, every payment trustlessly settled in tDUST.

The Protocol

How It Works

Three cryptographically enforced steps — from encrypted query to verified settlement.

Encrypt

Your query is encrypted client-side using zero-knowledge commitments. No raw data ever leaves your device — only a cryptographic envelope reaches the network.

Verify

The AI provider processes the encrypted payload in a confidential execution environment. A ZK proof of honest computation is anchored to the Midnight blockchain.

Settle

Once the on-chain proof is verified, a micropayment in tDUST tokens is released automatically to the provider. Trustless, instant, and auditable.

Why PrivateInfer

Privacy-First by Design

Every layer of the stack — from your browser to the blockchain — is built around your data never being exposed.

Zero Data Exposure

Queries are encrypted before submission. Providers compute over ciphertext — they never see your plaintext input or output.

ZK Proof Verified

Every inference result is accompanied by a zero-knowledge proof of correct execution, verifiable by anyone on the Midnight chain.

Trustless Settlement

Payments in tDUST are held in a smart escrow and released automatically upon on-chain proof verification — no intermediaries.

Midnight Native

Built entirely on the Midnight PREPROD network, leveraging its privacy-preserving smart contract primitives and DAppKit SDK.

Decentralized Providers

Any verified AI provider can register a model in the marketplace. No single point of failure, no central authority over inference.

Medical & Legal AI

Purpose-built for high-stakes domains where data sensitivity is non-negotiable — HIPAA-adjacent designs for medical and legal use cases.
