Post-quantum · On-chain · Independently verifiable

Trust you can
verify for yourself.

KXCO Verified seals domains, documents and identities with a post-quantum signature anchored on KXCO Chain — and lets anyone confirm it independently, without trusting KXCO. Checking is free.

Why it matters

Three things your badge proves — that no screenshot or certificate authority can.

🔐

Instant trust signal

Visitors see a badge that links directly to an on-chain record. No middleman, no expiry delay, no PDF to download.

⛓

Tamper-evident forever

The attestation is written to KXCO Chain. It cannot be altered, back-dated, or removed — even by KXCO.

🛡

Post-quantum ready

Signed with ML-DSA-65 — the post-quantum signature standard NIST published as FIPS 204 for the quantum era.

🔍

Independently verifiable

Anyone can verify your attestation directly via RPC using open-source tools. KXCO's servers are not in the verification path.

How it works

Three steps. Live in 24 hours.

Request

Tell KXCO which domain, document or identity to attest. We confirm scope and eligibility.

We attest

KXCO's scanner evaluates your domain, signs the result with ML-DSA-65, and writes the attestation to KXCO Chain.

Embed & go

Add one line of HTML to your site. The badge queries the chain in real time and turns grey the moment it's revoked.

What “Verified” means — and what it doesn’t

We say what we can prove. Nothing more.

✓

Cryptographic proof of integrity. The artifact matches the signed record. If configuration has changed since attestation, the signature fails.

✓

Tamper-evident, permanent record. Anchored on KXCO Chain and publicly readable. Verifiable without asking KXCO for anything.

✓

Post-quantum signature. ML-DSA-65 (NIST FIPS 204). Designed to resist attacks by quantum computers.

✗

KXCO Verified does not attest to the content of documents, legal validity, or regulatory status of any verified party.

Verify free. Get attested through KXCO.

Anyone can check an attestation for free. Issuing your own is part of a KXCO engagement.

Verify

Free

Check any domain or attestation yourself — no account, no fee. Verification runs against KXCO Chain via open-source tools; KXCO is never in the path.

Questions

Can someone fake the badge?

No. The badge is served live from KXCO Chain — it queries the actual on-chain record every time it loads. A copied badge image would be static and obviously fake. The real badge turns grey the moment an attestation is revoked or a subscription lapses.

What happens if an attestation lapses?

The badge enters a 30-day grace period (grey, unverified). After 30 days it displays the red Expired badge. The on-chain record remains permanently — only the active gate changes. Renewing the attestation restores the verified badge instantly.

How do I verify independently — without going through KXCO?

Use any JSON-RPC client pointed at https://chain.kxco.ai/rpc and call latest(keccak256(domain)) on the registry contract. No KXCO API involved. See the developer docs for a ready-to-run example.

What is ML-DSA-65 and why does it matter?

ML-DSA-65 is the post-quantum digital signature standard NIST published as FIPS 204. It is designed to resist attacks by quantum computers; ECDSA (used by most TLS certificates today) is not. KXCO Verified signs every attestation with ML-DSA-65.

How long does it take to go live?

Typically within 24 hours of confirmed scope. You'll receive the one-line embed code by email. The badge is live the moment the attestation transaction confirms on-chain.

Check any domain

Verify whether a domain has an active on-chain attestation.
