Post-quantum · On-chain · Independently verifiable
Cryptographic proof of integrity.
Anchored on-chain.
KXCO Verified seals domains, documents, and articles with ML-DSA-65 (NIST FIPS 204) signatures and records a tamper-evident attestation on KXCO Chain. Anyone can verify — without trusting KXCO.

Add one line of HTML. The badge queries the chain in real time — it turns grey the moment an attestation is revoked.
How it works
Three components. No trust assumptions.
1
Scan. KXCO's scanner evaluates your domain's post-quantum
cryptography posture, hashes the result, and creates a signed attestation
using ML-DSA-65 (FIPS 204 — the same algorithm NIST now mandates for
US federal systems).
2
Anchor. A compact record — the target hash, artifact hash,
score, and signer key ID — is written to
KXCO Chain
(Armature L1). The ledger is immutable; no entry can be altered or deleted.
3
Verify independently. Anyone can check the on-chain record
directly via RPC (
https://chain.kxco.ai/rpc), or use the open-source
kxco-verify
library. KXCO's servers are not in the verification path.
What “Verified” means — and what it doesn’t
We say what we can prove.
✓
Cryptographic proof of integrity. The artifact matches the
signed record. If the content or configuration has changed since attestation,
the signature fails.
✓
Tamper-evident record. The attestation is anchored to a public
blockchain. You can verify it without asking KXCO for anything.
✓
Independently verifiable signature. The ML-DSA-65 algorithm is
NIST FIPS 204, endorsed by the UK NCSC. The math is open. Anyone can re-run it.
✗
KXCO Verified does not attest to the content of documents,
the truthfulness of claims, legal validity, or FCA/SEC regulatory status
of any verified party.
