TrustLayer Foundation Launches ARIA: The Open Identity Protocol for AI Agents

Mexico City, April 1, 2026 — TrustLayer Foundation today announced the public launch of ARIA (Agent Registry for Identity & Authorization), an open protocol that gives every AI agent a verifiable, cryptographically-signed identity document anchored to the internet's existing DNS infrastructure.

ARIA addresses one of the most critical gaps in the current AI ecosystem: the absence of a standard, interoperable identity layer for AI agents. As autonomous AI agents increasingly take real-world actions — executing financial transactions, accessing sensitive data, and operating in multi-agent pipelines — the question "who is this agent and what is it authorized to do?" has no reliable answer.

"ARIA is to AI agent identity what DNS is to domain names," said Aaron Grego, CEO of TunoLabs and Founder of TrustLayer Foundation. "We built the infrastructure layer beneath every AI agent framework, giving the industry a shared, open foundation for trust."

ARIA is post-quantum native from launch, implementing ML-DSA-65 (NIST FIPS 204) hybrid signatures. It integrates with W3C Decentralized Identifiers, supports the Model Context Protocol (MCP), and introduces a four-level trust system (L0-L3) providing progressive verification from cryptographic self-signing to legal entity attestation.
