NEXT-GENERATION NOTARY NETWORK · A NEW KIND OF PRODUCT
Any action becomes a verifiable receipt the user holds and checks offline with open-source code. We don't store the content of your actions; the proof travels with you, as a receipt you keep.
TimeLayer is a next-generation notarial network. Today's digital notarization runs on a blockchain and on signatures (RSA/ECDSA) that a quantum computer will break. We use no blockchain, and trust doesn't rest on a single key — a quorum of independent nodes attests, and the proof is built on quantum-resistant hashes.
The proof rests on hash-linked structures and an independent quorum, not on a single key. We don't store the content of your actions, and because the proof is hash-based, a quantum break against RSA/ECDSA doesn't threaten it.
Honest status (test mode). Today the offline verifier proves a receipt is internally consistent and unchanged. The next step on our roadmap binds every receipt to the quorum's published keys (distributed k-of-n signatures), so that no single party — not even us — can fabricate one. Until that and an external review are done, we describe this as our construction and goal, not a finished guarantee. See the status note at the top of the page.
A receipt is attested by a quorum of independent nodes, not by one private key — the goal being that no single key, and no single server, is a point of failure.
We don't keep the content of your actions. The evidence lives with you as a small receipt; what the operator holds are compact proofs, not your data.
Verification is offline and open-source — run the verifier yourself and get a yes/no. It confirms the receipt is internally consistent and unchanged.
Most software defends itself by writing more — more logs, more queues, more monitors. That growing trail is also the attack surface. TimeLayer replaces the trail with a provable boundary: every meaningful action becomes a receipt the user already holds, and the operational garbage collapses. The software gets provable — and lighter.
Not different systems — different packagings of the same network. Tap any card for how it's used and where it fits.
Any action → a receipt → the user keeps it → anyone verifies. For SaaS, agent platforms, document workflows, legal-tech. Prove it happened and wasn't changed — without trusting the server.
Wrap one meaningful action — a payment, an approval, an order, a config change. The moment it's accepted you get a receipt; when it's done, a finality. No valid receipt, no action: if it can't be proven, the boundary safely refuses instead of half-succeeding.
SaaS, agent platforms, fintech approvals, legal-tech — anywhere "did this really happen, and was it changed?" must be answered without trusting the operator.
Every AI-agent action (issued an invoice, sent an email, made a decision) → an immutable receipt with memo + metadata. The agent carries proof of what it did, checkable by a third party.
Point your agent's tool-calls at TimeLayer. Every action it takes returns an immutable receipt with memo + metadata. The agent carries its own proof — instead of a mutable log someone could quietly edit after the fact.
Autonomous agents, AI ops, copilots acting on a user's behalf — anywhere a third party must later check what the agent actually did, not what a log claims it did.
Hash a document → get a receipt. Prove it's unchanged without storing the document itself. Zero-Data: we attest the fingerprint, never the contents — confidentiality stays intact.
Hash the document locally, send only the fingerprint, keep the receipt. You prove the file is byte-for-byte unchanged without ever uploading its contents — we never see the data.
Contracts, financial reports, legal evidence, intellectual property — anything where confidentiality must stay intact while authenticity has to be provable to a third party.
An external trust layer built on quantum-resistant hashes, so a quantum break against RSA/ECDSA passes it by. Not "we save your old wallets" — a parallel trust circuit on an independent quorum that doesn't need to migrate to PQC by construction.
Run it as a parallel trust circuit beside your existing PKI. Because the proofs are hash-based, a quantum break against RSA/ECDSA simply doesn't apply — there's nothing to migrate and no key whose lifetime you're betting on.
Long-lived records that must still verify in 10–20 years, and institutions that can't absorb a forced post-quantum migration of their whole signing stack.
Write only paid / final actions to the chain; everything else — moves, events, micro-actions — becomes fast off-chain receipts. Tens of thousands of attestations per second off-chain; the chain only carries what's actually worth money.
Keep only paid / final actions on-chain; turn every move, event and micro-action into a fast off-chain receipt. Players still hold a provable history of everything that happened — without paying gas for it.
On-chain games and high-frequency dapps — anywhere you're burning gas on actions that only need to be provable, not settled.
An open tool: anyone verifies any receipt offline. Published on GitHub. It proves the system is honest — verification without trusting us — and is the front door for developers.
Download the open-source verifier, drop in any receipt, get a yes/no offline in one command. No account, no call back to us — the proof is in the receipt, not on our server.
Due diligence, audits, integrators evaluating TimeLayer, and end-users who refuse to take a website's word for anything.
Send a document, video or any file — every piece carries a notarial seal, so the whole file arrives provably intact, in order, and tamper-evident. Swap a piece in transit and it shows instantly. Registered mail, notarial-grade — billed by the pieces it takes.
Pick a file. We certify its integrity map — each piece carries a seal — while the bytes travel by ordinary cheap transport. The receiver checks every piece against its seal; swap one in transit and it shows instantly.
Legal-document delivery, master video / footage handoff, any "registered mail, notarial-grade" transfer between two parties. Billed by the pieces it takes.
A receipt is a few kilobytes. Verification is one command, offline, against open-source code. Live in-browser demo is wired to our receiving API (coming online with launch).
// a verifiable receipt will appear here // TLCert : content identity + independent quorum // TLBundle : ~3 KB, the user keeps this // verify : tl_verifier verify receipt.tlcert receipt.tlbundle → VALID FINAL
The verifier is open-source so the verdict can't be faked by us: github.com/TimeLayer-OS/timelayer-verifier

The short version, in plain words.
A small certificate (a few 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.
No blockchain. Trust doesn't rest on a single key's signature — a quorum of independent nodes attests. On our roadmap, that quorum agreement is bound with distributed k-of-n signatures over a published key registry, so a receipt can't be fabricated by any single party. The proof is hash-based, so a quantum break against RSA/ECDSA doesn't threaten it.
Every action an AI agent takes — issuing an invoice, sending an email, making a decision — returns an immutable receipt with memo and metadata, so a third party can later verify what the agent actually did, instead of trusting a log it could edit.
Yes. You hash the document locally and send only the fingerprint. We record the fingerprint, never the contents — your data stays private while the receipt stays checkable by a third party.
The proofs are built on hash functions, which only lose a quadratic factor to quantum search (Grover) — so a quantum break against RSA/ECDSA doesn't threaten them. (The resistance comes from the hash basis, not from avoiding signatures.)
Download the open-source verifier, drop in any receipt, and get a yes/no offline in one command — no account, no call back to our servers. It confirms the receipt is internally consistent and unchanged.
We're pre-launch and we'd rather be honest than loud. Today the offline check proves a receipt is consistent and unchanged. Binding every receipt to the quorum's published keys (so no single party can fabricate one), independent node operators, public anchors and an external audit are on the roadmap — and we won't sell "unforgeable" as a finished fact until they're done.
