Cryptographic Evidence Ledger
Immutable cryptographic audit trails for AI systems. Every decision logged, hashed, and linked. Tampering detected instantly.
Built by engineers from Mastercard and Ford Models.
View Live DemoSHA-256 hashing ensures every AI decision, tool call, and output is cryptographically sealed. No record can be modified without detection.
Each event links to the previous hash, forming an unbreakable chain. Any modification breaks the chain and triggers immediate alerts.
Ed25519 signatures provide non-repudiation. Full audit trails meet regulatory requirements for AI governance and accountability.
