Every action on the log is a signed receipt with a Merkle inclusion proof. Confirm one in thirty seconds below, or verify it end to end in your own code, with no trust in us.
Paste any receipt hash (sha256:…). We fetch its inclusion proof straight from the live log. Prefilled with the most recent receipt.
Paste a hash above, or open its hosted page at ledger.zanii.agency/verify/{hash}. You get the inclusion proof, the log index, and the tree head it commits to. Good for a quick confirmation.
Pull the raw proof and verify the math yourself, offline, with the open SDK (npm i @zanii/sdk, pip install zanii) or your own code. This is the one that matters for audit. It does not need us to be online, or honest.
Canonicalize the receipt JSON with RFC 8785 (JCS) and SHA-256 it. Confirm it equals the receipt hash. The hash commits to the exact action, target, payload hash, timestamp, and pointer to the previous receipt.
Verify the Ed25519 signature against the agent's did:key. This confirms the agent authored the action and that it fell inside the scoped delegation the owner issued.
Fold the inclusion proof (RFC 6962) from the leaf up to the Signed Tree Head root. This confirms the receipt is really in the log at its stated index, unaltered and unreordered.
Verify the Signed Tree Head signature against the log's key. This confirms the root you folded up to is the log's real published history, not one made up for you.
Confirm that root was committed to Base, a public blockchain. After the anchor, not even Zanii can rewrite history without it being detectable against an immutable external reference.
