Trust / Attestation / Verify

In-browser verifier.

Drag a Felarity signed attestation chain JSON onto the box below. Verification runs entirely in your browser using WebCrypto, your chain JSON never leaves this machine, and no Felarity server is contacted at verification time.

How this works

The verifier executes the same three checks as our server-side endpoint:

  1. Walk each of the 8 nodes and recompute its node_hash as sha256(json.dumps(node_without_node_hash, sort_keys=True)). Any mismatch, a single character of tampering, invalidates the node.
  2. Confirm prev_hash chains from GENESIS through every node and matches the prior node's recomputed node_hash. The chain is hash-linked, so tampering at any node breaks every node downstream.
  3. Verify the signature over the final node_hash using the Felarity public key fetched from /.well-known/felarity-signing-key.pem. WebCrypto handles the cryptography; the verifier just feeds it bytes.
