Proof verification
Verify the authenticity and integrity of entries anchored on Madara L3.
What is L3 anchoring?
Each Brain Protocol entry is hashed via the Poseidon function (ZK-native, quantum-resistant) and the resulting hash is anchored on Madara L3 — a validity chain derived from Starknet.
This guarantees that no entry can be modified retroactively without the on-chain proof becoming invalid. Verification is public, without a trusted third party.

Manual verification via Brain MCP
If you have an entry's hash, you can verify it directly from your agent or terminal via the Brain MCP :
# Verification via Brain MCP brain verify --hash <entry-hash>
The verify tool is exposed in the proof group of the MCP server. Configure the MCP from the Settings page.
Security guarantees
- Poseidon hash — ZK-friendly, no trusted setup
- STARK proof — resistant to quantum computers (post-quantum)
- Public verification — any observer can recalculate the hash and compare
- On-chain immutability — anchor recorded in the Madara L3 contract
