Proof (formerly Notarize)

Proof, formerly known as Notarize, is the industry-standard platform for Remote Online Notarization (RON) and Digital Identity Verification (IDV). In the 2026 landscape, Proof has transitioned from a simple notarization marketplace to a comprehensive trust infrastructure. Its technical architecture centers on the 'Proof ID' system, which utilizes AI-driven forensic analysis to validate government-issued IDs and biometric data in real-time. The platform facilitates secure, legally-binding transactions through a combination of WebRTC-based encrypted video sessions and X.509 digital certificates for cryptographic document sealing. It is engineered for high-compliance sectors including real estate, financial services, and legal, maintaining strict adherence to MISMO standards and the SECURE Notarization Act. By integrating sophisticated Fraud Detection logic that analyzes session metadata and signer behavior, Proof provides a higher level of assurance than traditional in-person notarization. Its enterprise-grade API allows for seamless embedding of identity-assured signatures into native workflows, making it a critical component of the modern digital contract lifecycle.
