Peer-to-peer marketplace for AI inference. A global mesh of machines serving models across the network - making AI decentralized, uncensorable, and provably private.

Halo is a permissionless peer-to-peer marketplace for AI inference built on Base.

Its purpose is simple and radical: anyone, anywhere can access any model - no account, no API key, no gatekeeper.

Operators around the world serve the models they have access to - from frontier APIs to open-weights models served on their own hardware - and the network aggregates that access into a single marketplace that no company controls and no jurisdiction can switch off.

The result: AI that lives everywhere and belongs to no one.

Use Cases

Access to Inference

Agents and humans have access to permissionless P2P inference.

AI Model Reselling

Operators can resell their models on a per inference basis with payments settled onchain via stablecoins on Base.

Confidential Compute (TEEs)

Users and agents can access fully confidential compute through operators that run on TEEs.
