Record types

Event

Paste an Event ID to fetch the signed envelope and confirm the record has not changed since it was written to the ledger.

Verify event

AI attestation

Paste an Attestation ID to fetch the signed record of a model exchange and check that the input and output you hold are the ones that were attested.

Verify ai attestation

Document

Paste the Event ID from a document's proof link, then choose the file you hold. It is hashed in your browser and the hash is compared with the anchored one.

Verify document

Trace

Paste a Trace ID to open a sealed bundle: every event, document and AI attestation it groups, in order, with the composite hash that closes it.

Verify trace

Audit log

Paste an Audit Event ID from an export, a SIEM delivery or the audit portal to confirm the event is genuine and unchanged.

What a proof page showsHow it works
  • The issuer, and whether its domain is verified
  • The SHA-256 hashes that were signed
  • The Ed25519 signature and the public key that made it
  • When the record was ingested or anchored
  • A verdict for the copy you hold, when you submit one
Never shownPayloads, documents, prompts and outputs. Only their hashes are public.
Hash checksA pasted hash is compared in your browser. A pasted payload or a file is hashed and checked against the signed record once, then discarded.
OfflineThe Node and Python SDKs verify audit exports against the issuer's public key without Invoance. Audit log docs

Verified documents and records. Invoance records the exact version of every invoice, report and notice your company sends, so the people who receive them can confirm they have the version you sent, without taking your word for it.
