Proof-of-Inference (PoI)

Proof-of-Inference (PoI) is Hubic’s core mechanism for ensuring the authenticity of every AI-generated output. Each inference must be accompanied by a zero-knowledge proof (zk-proof), generated off-chain and verified on-chain through Ethereum smart contracts.

✅ Guarantees:

• The model used is identified by a unique cryptographic hash.

• Inputs are cryptographically committed and remain unchanged.

• Outputs are deterministically derived from a registered zk-compatible model.

• All outputs are verified on-chain before they can trigger any downstream logic.

🔁 Inference Flow:

User Input → zk-Inference Node → zk-Proof + Output → Ethereum Verifier Contract → On-Chain Result

🧠 Why It Matters:

• Enables trustless, cryptographically guaranteed AI predictions.

• Allows DeFi, DAOs and RWA contracts to depend on provable AI logic.

• Preserves user privacy by never exposing raw inputs or outputs on-chain.

• Creates a transparent audit trail for all inference activity.

🌍 RWA Integration:

PoI is critical to RWA tokenization — every zk-verified inference can serve as an on-chain proof of usage. These verifiable interactions underpin smart contracts that distribute revenue to RWA token holders, making AI outputs tangible, auditable and financially productive assets.
