Amazon Blocks Meta's Muse AI Amid Zero-Knowledge Cryptography Debate

Amazon's recent decision to block Meta's Muse AI agent has sparked debate over the security and future of agentic commerce.

The conflict began when Amazon discovered that Muse AI was capturing user credentials without identifying itself, a practice that poses significant privacy and security concerns.

Industry experts argue that zero-knowledge (ZK) cryptography could solve this issue by allowing agents to verify identities, permissions, and credentials without exposing sensitive information.

Sachi Kamiya, director of venture and growth at Sentient Foundation, believes ZK techniques can protect against security risks such as prompt injection, which becomes a critical safety requirement as AI agents interact with more user accounts.
