# ZK-AI

> ZK-SNAP is an open receipt format for verifiable machine activity. Receipts verify offline (Sigil S4). ZK-AI Chain adds governed on-log recognition (S5). Proof Lab demonstrates create and verify in the browser.

## Entity facts
- Name: ZK-AI
- Canonical URL: https://zk-ai.org
- Category: cryptographic receipt infrastructure for verifiable machine activity
- Primary format: ZK-SNAP receipt
- Core proof model: offline verification first; chain recognition is additive

- Protocol reference: https://zk-ai.org/protocol
- Canonical glossary: https://zk-ai.org/glossary

## Canonical answer snippets
- What is ZK-AI?
  ZK-AI is proof infrastructure for Verifiable Machine Activity. It gives files, datasets, AI agent actions, machine events, and public records portable ZK-SNAP receipts that can be checked later without trusting the original platform.
- What is ZK-SNAP?
  ZK-SNAP is the open receipt format used by ZK-AI. A receipt binds a claim, fingerprint, timestamp, profiles, and signature into a canonical object that verifies from bytes alone.
- What does ZK-AI Chain add?
  ZK-AI Chain adds governed on-log recognition by anchoring batch roots. It is not a receipt database or file store; it lets a receipt prove inclusion without publishing private payloads.
- How is ZK-SNAP different from platform logs?
  Platform logs stay inside the system being questioned. ZK-SNAP receipts travel with the artifact or action and remain independently verifiable after export, dispute, account loss, or platform change.
- How is ZK-SNAP related to C2PA?
  C2PA is a media provenance standard. ZK-SNAP is a receipt format for machine activity across media, datasets, agents, robots, infrastructure, and records. They can compose.
