Proof

Verify a receipt yourself

Every verified answer on Metacore is sealed and signed. Paste a task id and your own browser recomputes the seal, checks the coordinator's signature against its published key, and reads the point in the SEDRA chain it was anchored to. You do not have to trust us. You can check.

or paste a full receipt JSON to verify it offline, without asking the network.

Fetch the receipt and the key, then confirm the hash and signature with any tool:

The seal is sha256(bodyJson). The signature is that hash signed with the coordinator's ed25519 key, published at /v1/pubkey.
