01 • THE PROBLEM
Sensitive AI needs utility without data exposure.
Critical industries are blocked by a simple trade-off: powerful inference vs. confidential data.
THE PRIVACY GAP
Send data to a centralized model → lose control. | Put data on a public ledger → create permanent exposure.
01
Centralized AI APIs
Confidential prompts and records leave the organization and become dependent on a third party.
02
Public Blockchains
Sensitive payloads cannot safely live in immutable public state, even when access is controlled.
03
Trust Gap
A provider may return an answer — but users need a way to verify execution without revealing the data.
PrivateInfer is designed around the verification layer — not just the inference layer.

02 • THE PRODUCT
PrivateInfer turns confidential inference into a verifiable workflow.
Execution stays off-chain; the Midnight network coordinates state, proof verification and settlement.
01
Encrypt
Query Maker encrypts sensitive input locally.
02
Process
Provider executes the model inside a protected TEE.
03
Prove
Provider returns an inference result + ZK proof.
04
Settle
Smart contract verifies proof and releases tDUST escrow.
CORE PROMISE
The ledger sees proof.�The provider sees only what�it needs to execute.

06 • PROVIDER HUB
Providers monetize AI without becoming a data honeypot.
The provider receives a job through the marketplace, executes it in a protected runtime and submits verifiable output.

07 • TRUST MODEL
Three controls close the trust gap.
PrivateInfer combines confidentiality, verifiability and economic settlement in one workflow.
01
Confidentiality
Encrypted inputs + private witnesses keep sensitive payloads out of public state.
02
Verifiability
A proof-backed result lets the contract validate the requested computation before settlement.
03
Accountability
Escrow aligns payment with successful verification instead of blind trust in a provider.
