Trust Without Disclosure: Why Zero-Knowledge Proofs Could Help Build Trust in AI Agents

We’re moving from systems that respond to our questions to AI agents that act on our behalf. In this new era, AI agents can help book travel, manage tasks, and coordinate across systems, with less human intervention at each step. This creates a practical problem: How do we trust these agents? How do we verify what they are allowed to do, or what they have done, without exposing sensitive information? Enter zero-knowledge proofs—a cryptographic technique that lets you prove you know something without revealing what you know. It sounds like a magic trick, and in many ways, it is.
