Digital identity systems were built for humans logging into systems. Authentication meant proving someone could log in. Authorisation meant granting access. Accountability meant finding the human who made a decision. Autonomous AI breaks this model. Agents run continuously across tools, clouds, and organizations. They make decisions, initiate transactions, invoke APIs, and coordinate with other agents - often acting for multiple people, policies, and institutions at once. The question isn’t just who logged in anymore. It’s what actor was authorised to take this action, on whose behalf, and under what constraints.

​
Why Identity Alone Is No Longer Enough

Traditional identity verification establishes who or what something is. For autonomous systems, that’s not enough. An AI agent can have a valid identity and still act outside its mandate - invoking the wrong tool, accessing data without consent, or triggering outcomes that can’t be justified later. When identity systems stop at access control, they can’t answer the questions that matter once actions happen:
  • Was this action permitted?
  • Under which policy?
  • On whose behalf?
  • With what declared intent?
  • Can this be proven after execution?
Without verifiable answers, trust breaks down.

​
The Visibility Problem in Autonomous Systems

As autonomy increases, visibility decreases. AI agents operate at machine speed across distributed environments through abstraction layers that weren’t designed to preserve provenance. Logs fragment across systems. Context gets lost between calls. Authority is implied, not proven. In practice, organizations can’t reliably reconstruct:
  • What decision led to an action
  • Which policies were evaluated
  • Whether consent was valid at the time
  • Who ultimately bore responsibility
This isn’t just an operational problem. It’s a regulatory, legal, and governance risk.

​
Why Fraud and Deepfakes Are Only Part of the Story

Most of the conversation focuses on deepfakes, bots, and synthetic fraud. These are real risks - but they’re symptoms, not the root cause. The deeper issue is the absence of a shared mechanism to prove authority and intent when non-human actors take actions. Even legitimate, well-intentioned AI systems become untrustworthy if their actions can’t be independently verified. Trust fails not because systems are malicious, but because outcomes can’t be proven.

​
Agent Protocols Create Capability - Not Trust

Protocols like Model Context Protocol (MCP) and Agent-to-Agent (A2A) let agents:
  • Discover tools
  • Exchange context
  • Coordinate actions
These protocols are foundational for agent interoperability. But they don’t answer core trust questions:
  • Who issued this agent?
  • What authority does it have?
  • What policies apply to this action?
  • Can the outcome be audited independently?
Protocols enable capability. They don’t establish trust.

​
The Trust Gap

There’s a growing gap between what autonomous systems can do and what organizations can safely justify. As AI systems act across organizational, regulatory, and jurisdictional boundaries, this gap widens. Without a way to bind identity, authority, intent, consent, and outcome together:
  • AI initiatives stay stuck in pilots
  • Autonomous actions get constrained or disabled
  • Risk gets managed by limitation, not design
This is the trust gap in autonomous AI.

​
What a Trust Layer Must Provide

Closing this gap doesn’t require replacing existing systems. It requires a trust layer that operates above them - one that travels with actions rather than staying confined to logins or platforms. This layer must:
  • Establish verifiable identity for all actors, human and non-human
  • Bind actions to declared intent and applicable policy
  • Preserve consent across system boundaries
  • Produce cryptographic evidence suitable for audit and investigation
  • Remain neutral across clouds, identity providers, and protocols
Only when trust travels with action can autonomous AI operate safely at scale.

How This Relates to Nuggets

Nuggets is designed to address this trust gap. The rest of the documentation explains how Nuggets implements a universal trust layer that makes autonomous actions provable, auditable, and compliant by default - without replacing existing identity or cloud infrastructure.
