What is KXCO Verified?
The first post-quantum identity credential anchored permanently on a private blockchain.
⛓️
On-chain · permanent
Every credential is written to KXCO Chain (Armature L1) — a private QBFT blockchain with 0.4s finality. The record is immutable. No server can delete it.
🔐
Post-quantum cryptography
Signed with ML-DSA-65 — the NIST-standardised quantum-resistant signature algorithm (FIPS 204). Safe against both classical and quantum adversaries.
🔍
Independently verifiable
Anyone can verify this credential using the open-source
kxco-verify library — available on npm, PyPI, crates.io, and pkg.go.dev. No account. No API key. No KXCO server required.🪙
Soulbound token
Each credential mints a KXCOIdentityToken — a non-transferable ERC-style token on-chain. It is permanently bound to the holder's wallet. Cannot be sold, transferred, or faked.
What you can use it for
✓ Professional identity on LinkedIn & social profiles
✓ Email signature credibility signal
✓ Proof of identity in contracts & NDAs
✓ On-chain wallet identity for Web3 interactions
✓ Verifiable background check supplement
✓ Digital signature context for advisory work
✓ Business correspondence authentication
✓ Cross-border corporate identity verification
