▪ Verifier

Verify any Ryvion receipt.

Paste a TranscriptDigest CID. No auth. We return the lineage and the signature reference. Cross-check it against our public key bundle in your terminal — Ryvion holds no secret you need to be granted.

▪ verifier

no auth · no rate limit

Don't have a CID handy?

▪ How verification works

Four steps,all transparent.

step 01

You paste a CID

TranscriptDigest CID or output hash. No auth, no API key, no rate limit on lookup.

step 02

We resolve the object

The hub looks up the content-addressed receipt and returns the redacted envelope.

step 03

We walk the lineage

PromptRoot, Policy, ExecutionPlan, Assignment, TranscriptDigest, TargetReceipt — each is content-addressed and resolvable.

step 04

You see the chain + signature

Lineage tree, Ed25519 signature reference, and node hardware. Re-verify offline against our public key bundle.

▪ Verify offline

Don't trust us.Verify in your terminal.

Pull our public key bundle, recompute the canonical envelope, validate the Ed25519 signature locally. Works in Node, Deno, Bun, or browser.

// 1. Pull the receipt from your local export.
