Everything you need to know about S4 Ledger, blockchain verification, and defense integration.
No. Only SHA-256 hashes (cryptographic fingerprints) are stored on-chain. The hash is a one-way function — the original data cannot be recovered from it. No CUI, no ITAR content, no PII ever touches the blockchain.
Via Python SDK or REST API. S4 Ledger connects to existing logistics systems like 3-M/SCLSIS, OARS, NTCSS, CDMD-OA, and NAVSUP OneTouch. Records flow automatically — no manual data entry required.
$SLS (Secure Logistics Standard) is a utility token on the XRP Ledger. It functions like postage stamps — each anchor costs $0.01 in $SLS. As an XRPL-native token, $SLS can be traded on XRPL decentralized exchanges (DEXs), but its primary purpose is utilitarian: paying verification fees to anchor defense records on-chain. It is not equity and not a security.
S4 Ledger is designed to align with NIST SP 800-171, CMMC Level 2, and DFARS 252.204-7012. The architecture ensures zero sensitive data on-chain, supports on-premises deployment for classified environments, and maintains full audit trails.
XRPL offers 3–5 second finality at fractions of a cent per transaction, with 99.99% uptime since 2012. Ethereum costs $5–50+ per transaction. Private chains create vendor lock-in. XRPL is public, neutral, and independently verifiable.
Yes. The Pilot tier includes up to 10,000 free anchors on XRPL Mainnet, full SDK access, and Anchor-S4. No credit card required.
Yes. 500+ pre-loaded defense platforms are available, plus a custom entry option for any platform, vessel, hull number, or program not yet in the database. Works with your actual data.
Unclassified, CUI, Secret (SIPRNet), and Top Secret (JWICS). Cloud deployment for unclassified environments, on-premises for classified. The architecture supports air-gapped operation.
Self-funded (IRAD). Pursuing SBIR/STTR opportunities, strategic investment, and government pilot program funding.
