Darkbloom: Private AI Inference on Idle Macs

Darkbloom is a decentralized inference network that connects AI consumers with Mac owners running idle Apple Silicon hardware. As a consumer, you get access to frontier-quality models through an OpenAI-compatible API — with end-to-end encryption ensuring your prompts stay private. As a provider, you earn by running inference on your Mac during idle hours.

Call the API

Make your first inference request in under 5 minutes using any OpenAI SDK.

How it works

Darkbloom runs on a three-layer architecture: your requests go to a coordinator running in a Confidential VM, which routes them to attested provider machines running hardened inference processes on Apple Silicon.

Consumer (SDK / Web UI / curl)
    │
    │  HTTPS, OpenAI-compatible API
    ▼
Coordinator (Confidential VM, encrypted memory)
    │
    │  WebSocket — request re-encrypted to provider's key
    ▼
Provider (hardened process on Apple Silicon)
    │
    │  inference engine

The coordinator encrypts each request with the destination provider’s public key before forwarding it. Only the hardened provider process — running with debugger attachment blocked and memory-reading APIs disabled — can decrypt and process the request.
