TrustNXT

What TrustNXT does

TrustNXT is a cryptography startup based in Hamburg that serves as the Zero Trust enabler for autonomous systems and decentralized networks. The company guarantees real-time data integrity directly at the source, transforming vulnerable sensor streams into tamper-proof, legally compliant evidence. Their technology provides absolute verifiability for drone fleets, robotics, or critical infrastructure, meeting business and regulatory demands. TrustNXT secures data, reduces operational risks, and makes Physical AI audit-ready and legally defensible. They build a new Trust Layer acting as the Immune System for the Post-Truth World, securing data directly at the edge and creating a resilient data trail across decentralized networks.

Products

• Cross-Device-Notary ServiceMachines and sensors mutually verify each other's data and act as decentralized notaries directly at the edge.
• Zero Trust ArchitectureData is cryptographically secured at the physical source as a preventive measure, operating exclusively on a fully traceable basis.
• DePIN PowerhouseScalable, decentralized physical infrastructure networks (DePINs) that establish trust anchors independent of central clouds.
• Mutual WitnessingTransforms networked cameras, drones, or robots into a collective verification system where each device acts as a cryptographic notary for others, creating an unbreakable, immutable data chain.
• Data ChainProactive protection against data injection, splicing, and deletion. Generates a completely tamper-proof and legally admissible timeline for live video and sensor data directly at the source.
• VideoconferencingHighly secure videoconferencing solution providing hardware-based sealing, compression tolerance, and proactive prevention against deepfakes and stream injections.
• Visual HandshakeInteractive, mathematical exchange of cryptographic credentials via camera display for maximum protection against spoofing, creating an unbreakable link between digital identity and physical presence, and generating audit-ready documentation for critical handovers.
