Question 1

What is a notarial receipt?

Accepted Answer

A small certificate (about 1.5 KB) that records a specific action or document. You keep it yourself and anyone can verify it offline with our open-source verifier; it confirms the receipt is internally consistent and unchanged.

Question 2

Does TimeLayer use a blockchain or signatures?

Accepted Answer

No blockchain. Trust doesn't rest on a single key's signature — an independent quorum attests. Each receipt is signed by a quorum of independent operators (Ed25519), and their public keys are published for independent cross-check, so no single party — including us — can fabricate one. The data commitment is hash-based and algorithm-agnostic — SHA-256, BLAKE3, SHA-3, or any standard hash is accepted. Hash functions are quantum-resilient (Grover only gives quadratic speedup). The signing layer uses Ed25519 (classical ECC, same as TLS and SSH today); a signing-layer upgrade to post-quantum schemes would not require re-notarizing existing receipts.

Question 3

How do you notarize AI-agent actions?

Accepted Answer

Every action an AI agent takes — issuing an invoice, sending an email, making a decision — returns a tamper-evident receipt with memo and metadata, so a third party can later verify what the agent actually did.

Question 4

Can I attest a document without uploading it?

Accepted Answer

Yes. You hash the document locally and send only the fingerprint. We attest the fingerprint, never the contents — confidentiality stays intact while authenticity stays provable to a third party.

Question 5

Is TimeLayer quantum-resistant?

Accepted Answer

Two layers, two honest answers. The data commitment is hash-based and algorithm-agnostic (SHA-256, BLAKE3, SHA-3 and others are accepted). Hash functions only lose a quadratic factor to Grover's algorithm, so the hash binding remains strong against quantum computers. The signing layer uses Ed25519, the same classical ECC used by TLS and SSH — it is not post-quantum. If large-scale quantum computers become practical, the signing layer would need to migrate to post-quantum schemes (e.g. CRYSTALS-Dilithium). That migration does not invalidate existing receipts: the hash commitment layer is already quantum-resilient.

Question 6

How do I verify a receipt?

Accepted Answer

Download the open-source Public Verifier, drop in any receipt, and get a yes/no offline in one command. No account and no call back to our servers.
