Ethereum's ERC-8004 proposal and Virtuals' ACP protocol are collaborating to establish a decentralized AI agent economy. ERC-8004 introduces on-chain identity, reputation, and validation registries, facilitating trustless interactions among AI agents. Meanwhile, Virtuals offers a platform for users to create and monetize AI agents with minimal entry barriers. This collaboration positions ERC-8004 as a foundational standard and Virtuals as an application layer, aiming to enhance cross-chain interoperability and attract developers to the AI agent ecosystem.
