Post-Quantum Secure · DOD-Grade Security
Built for title companies, law firms, and government agencies that demand the highest level of document security and compliance
Quantum-Resistant by Design
OnChainESign uses SHA-256 cryptographic hashing — classified by NIST as quantum-resistant for data integrity. Even future quantum computers cannot reverse-engineer a document from its hash or forge a collision. Your signed documents are future-proof against both classical and quantum threats.
DOD & Federal Compliance
Our platform aligns with NIST SP 800-171 controls for protecting Controlled Unclassified Information (CUI), FIPS 180-4 compliant hashing, and the DOD's Zero Trust Architecture mandate. Blockchain immutability provides non-repudiation that exceeds traditional PKI-based digital signature requirements.
Title Company & RON Ready
Purpose-built for real estate closings with multi-party signing, role-based field assignment, and audit trails that satisfy Remote Online Notarization (RON) requirements. Compatible with ALTA Best Practices and state-specific e-recording standards for deeds, mortgages, and title transfers.
