What KXCO does

KXCO is a private post-quantum cryptography infrastructure company headquartered in Bangkok, Thailand, founded in 2017 by Shayne Heffernan Ph.D. It builds and operates Armature L1, a proprietary post-quantum blockchain that signs every transaction with NIST FIPS 204 (ML-DSA-65) and implements FIPS 203 (ML-KEM) and 205 (SLH-DSA). On top of Armature L1 the company offers five products: Armature L1 itself as a settlement and identity layer, PQC Hosting + Bastion for quantum-safe deployment signing and vulnerability scanning, KXCO Sign for long-lived document signing, KXCO Verified for institutional and AI-agent identity, and KnightsVault (in beta), a white-label banking and exchange stack for licensed financial institutions.

The company targets three customer segments — corporates with multi-decade audit obligations, regulated institutions facing NIST/G7/NSA post-quantum migration deadlines, and AI agents requiring verifiable on-chain identity. Revenue is generated through subscription-based pricing on PQC Hosting, KXCO Sign, and KXCO Verified, and a licensing model on KnightsVault. Go-to-market is a hybrid of enterprise field sales ("Request a briefing," "Talk to KXCO AI") and self-serve product portals, with no publicly disclosed pricing. The firm claims 10 billion+ signatures secured on-chain, a live public block explorer at chain.kxco.ai, and production compliance with post-quantum standards that become mandatory under US federal timelines by 2029.

Strategically, KXCO is in an early commercialization phase. Only one $6M funding round from 2017 is on record, no named enterprise customers are disclosed, and KnightsVault remains in beta. A February 2026 partnership with Relworx to deploy Armature L1 in African remittance markets (Nigeria, Kenya, South Africa) represents the most concrete commercial expansion signal and positions the company against a $50B annual addressable market, though prototypes are not expected until mid-2026.

Revenue model

1. PQC Hosting + Bastion: Subscription-based quantum-safe deployment security. Provides PQC Host for signing deployments with ML-DSA-65 and Bastion for continuous scanning of quantum-vulnerable algorithms with compliance report generation.
2. KXCO Sign: Document signing service with post-quantum signatures. Generates on-chain verification records on Armature L1 for contracts, board resolutions, and regulatory submissions.
3. KXCO Verified: Identity verification service for institutions and AI agents. Identity registered on Armature L1 with ML-DSA-65, verified directly on-chain by counterparties.
4. KnightsVault White-Label Banking: White-label banking and exchange infrastructure for licensed financial institutions. KXCO provides software; institution provides license. Beta stage with production launch pending.

Core offering

KXCO delivers post-quantum cryptographic infrastructure built on Armature L1, its proprietary post-quantum blockchain. The operating portfolio includes Armature L1 (the settlement, identity, and execution layer), PQC Hosting + Bastion (deployment security with on-chain signed build history and continuous vulnerability scanning), KXCO Sign (ML-DSA-65 document signing), and KXCO Verified (decentralized identity verification for institutions and AI agents). Every operation generates an independently auditable on-chain record signed with NIST FIPS 204 ML-DSA-65, and the chain is publicly inspectable via the block explorer at chain.kxco.ai.

Product overview

KXCO delivers next-generation post-quantum cryptographic infrastructure for corporates, institutions, and AI agents. The portfolio consists of five products built on Armature L1, a live post-quantum blockchain: Armature L1 (the core settlement, identity, and execution layer), PQC Hosting + Bastion (deployment security and vulnerability scanning), KXCO Sign (document signing), KXCO Verified (identity verification), and KnightsVault (white-label banking and exchange, currently in beta). All products generate on-chain records with ML-DSA-65 signatures and are independently auditable without requiring trust in KXCO.

Products and services

• Armature L1 Post-quantum blockchain serving as the settlement, identity, and execution layer. Features ML-DSA-65 signatures on every transaction, 0.4-second block finality, and native tokenization of digital and real-world assets. Supports institutional identity, AI agent credentials, and smart-contract settlement. Public block explorer at chain.kxco.ai enables independent audit.
• PQC Hosting + Bastion Deployment security product that signs every code deployment with ML-DSA-65 and records it on Armature L1, creating a verifiable build history. Bastion scans code, dependencies, configs, containers, and TLS for quantum-vulnerable algorithms and produces compliance reports for auditors. Integrates with existing CI/CD pipelines.
• KXCO Sign Document signing solution where every signature is ML-DSA-65, resistant to quantum attacks today and in the future. Generates on-chain verification records on Armature L1 for contracts, board resolutions, and regulatory submissions with decades-long validity requirements. Counterparties verify without a KXCO API or intermediary.
• KXCO Verified Identity verification platform that registers institutional and AI agent identity on Armature L1 with ML-DSA-65 credentials. Counterparties verify directly on-chain without a KXCO API or intermediary. Applies the same standard to humans, institutions, and autonomous AI agents, with built-in KYC/AML enforcement at the protocol level.

Direct peers

• Civic: Decentralized identity verification platform for individuals and institutions. Closest functional competitor to KXCO Verified, though Civic is not natively post-quantum.
• Abelian: Layer-1 blockchain purpose-built with NIST-standardized post-quantum signatures (Dilithium/ML-DSA). Direct alternative to Armature L1 for institutions seeking quantum-safe chain infrastructure.
• Quantum Resistant Ledger (QRL): Post-quantum-first Layer-1 blockchain using XMSS hash-based signatures. Most direct competitor to Armature L1 for quantum-resistant settlement and digital asset issuance.

Broad incumbents

• Hedera Hashgraph: Enterprise-grade distributed ledger with permissioned deployment, identity, and tokenization services. Comparable institutional GTM motion to Armature L1, with active PQC roadmap.
• Polygon Labs: Major EVM-compatible L2 with tokenization, identity, and ZK tooling that overlaps with KnightsVault and Armature L1 use cases. Polygon has announced PQC-focused research tracks.
• Cloudflare Post-Quantum: Provides post-quantum TLS and identity services across its edge network. Competes at the protocol/transport layer where many enterprises will first encounter PQC migration tooling.
• AWS KMS / Amazon Quantum Ledger Database: Hyperscaler key management and immutable ledger services; AWS is actively adding PQC primitives (ML-KEM/ML-DSA). Competes with KXCO's signing, hosting, and audit-trail use cases as a default for cloud-native institutions.
• IBM Quantum Safe: IBM's enterprise quantum-safe cryptography suite spanning key management, TLS, and code-transformation tooling. Comparable to KXCO's PQC Hosting + Bastion module but sold into a much broader enterprise stack.

Emerging players

• Dock Labs (DOCK): Decentralized verifiable-credential platform with reusable KYC. Adjacent to KXCO Verified, particularly for AI-agent credential issuance where Dock is positioning.
• SEALSQ (WISeKey): Semiconductor and PKI provider offering post-quantum secure elements and identity chips for IoT and institutions. Overlaps with KXCO Verified and KXCO Sign for hardware-rooted identity use cases.
