Envelope nel ledger
…
How to read this page
- Crovia publishes two JSON files per observation: an envelope (the signed record, shown in the cockpit) and a proof bundle (the envelope plus the Merkle path, the seal signature, and the Bitcoin anchor — fetched here).
- Paste an
axm_…id. This page downloads only the proof bundle and runs every cryptographic check locally. Nothing is ever sent back to Crovia. - A 404 / bundle not yet available means the envelope is newer than the last bundle batch. Bundles are regenerated hourly at :15 UTC. The Bitcoin anchor itself is upgraded daily at 04:00 UTC.
- See the AXIOM Receipt v1 spec to implement your own verifier.
Paste an axiom_id to start.
Every Crovia observation is a signed AXIOM envelope. This page retrieves the envelope's proof bundle and verifies four independent layers of evidence directly in your browser: content integrity, Ed25519 signature, Merkle inclusion in a sealed batch, and OpenTimestamps anchor in the Bitcoin blockchain.
