Nexart

NexArt provides independently verifiable evidence of what AI systems actually execute through cryptographically signed Certified Execution Records. The platform captures key execution details, including inputs, outputs, parameters, model identifiers, and timestamps, creating an evidence layer that is independent of the system being audited. Confidential mode keeps sensitive data protected by using hash-bound commitments, while third parties can independently verify signatures and timestamps using standard cryptographic tools. Built on open standards such as SHA-256, Ed25519, and RFC 3161, NexArt helps organizations in regulated industries strengthen AI accountability, auditability, and transparency when AI-driven decisions need to be verified or challenged.
