Show HN: Verigate – Cryptographic authorization receipts for AI agents (verigate.cloud)

Verigate has announced a groundbreaking tool for AI agents, introducing cryptographic authorization receipts that ensure compliance and verifiable identities without relying on large language models (LLMs). Each action taken by an AI agent is processed through a deterministic gateway that issues Ed25519-signed receipts, forming a tamper-evident audit trail by chaining each receipt to its predecessor. This innovation is crucial for the AI/ML community, especially in the context of increased regulatory scrutiny following the EU AI Act and other frameworks, as it offers automated compliance reports to help organizations meet requirements for high-risk AI systems. The technical architecture employs Merkle trees for receipt organization and anchors them to Base L2, enabling independent verification of the entire receipt chain. The system not only reinforces the integrity of AI operations but also enhances security through DPoP-bound registrations and liveness challenges to verify agent identity. With provisions for offline verification and no per-seat fees, Verigate offers a practical solution for organizations to maintain rigorous oversight and traceability for AI activities, paving the way for more robust and accountable AI implementations.
