Blockchain Verifier

Verify a Nostr event notarization directly on the Bitcoin blockchain.

This verification is independent of our database - it queries our Bitcoin Core full node directly to confirm your event was notarized on-chain.

The event ID you want to verify was notarized

The Bitcoin transaction that contains the notarization

How verification works

  • 1.We query the transaction directly from our Bitcoin Core full node (not our database)
  • 2.For timestamps, we check if the OP_RETURN output contains your event ID
  • 3.For inscriptions, we fetch the Ordinal content from ordinals.com and verify it matches
  • 4.This proves the notarization exists on Bitcoin independent of any database
