RFC 3161 · Global trusted timestamp

Give every AI creation
a proof trail

The faster agents ship, the more proof matters. Lanveris gives every agent output a verifiable source and time.

Workflow

Four steps, so outputs can prove themselves

Connect once. Every later agent output can be timestamped, archived, and verified.

01
$ install lanveris-cli
→ ok

Connect

Give the setup link to your agent. It installs the tool, registers itself, and gets to work.

02
batch · merkle root signed

Register

When a file is produced, the CLI submits only its fingerprint. Lanveris batches records and writes the credential back.

Records

After login, you can see what each agent registered and copy public verification links.

04
⤓Drop a file to verify

Verify

Drop a file to verify source and integrity. Offline verification works with a single command.

One-line setup

Send one instruction to your agent,
and it handles the rest

Your agent installs the CLI, registers itself, starts timestamping, and gives you a Claim your agent link. No manual setup.

Please read https://direct-stage.lanveris.net/skill.md and connect to Lanveris

The fingerprint is calculated locally. Your file content never leaves the device.

Why trust it

Not platform promises, cryptography and standards

The proof anchors to an international standard, not to a single platform's word.

Files never upload

The fingerprint is calculated locally. The platform receives only a fingerprint and agent label, not the file bytes.

Portable credentials

Each .lanveris file contains the fingerprint, Merkle path, and timestamp evidence, so it can be verified independently.

Trusted time anchor

DigiCert and other timestamp authorities issue RFC 3161 timestamps, the same family of trust used by digital certificates.

FAQ

Questions about proof

Why is the time trustworthy?

The time is not asserted by Lanveris. It is issued by trusted timestamp authorities such as DigiCert under RFC 3161. Lanveris batches fingerprints into a Merkle tree and timestamps the root, so each record can independently trace back to that timestamp.

Does Lanveris upload my file?

No. The fingerprint is calculated locally. Lanveris receives only the fingerprint and agent label. File content never leaves your device by design.

How can someone else verify my output?

They can use the web verifier to calculate the fingerprint locally, or verify offline with the .lanveris credential sent alongside the file.

What makes the credential independent?

The credential contains the fingerprint, Merkle path, and timestamp evidence. It anchors to RFC 3161 rather than to a single platform account.

Does this prove legal authorship?

It proves existence, time, integrity, and the registering agent label. Legal authorship and ownership still depend on legal context.
