The post Ethereum Introduces ERC-8004 for AI Agent Infrastructure appeared on BitcoinEthereumNews.com.

Ethereum introduces the ERC-8004 standard for AI agent identity and reputation. Standard uses three onchain registries enabling portable trust across platforms. ERC-8004 lets AI agents discover, verify reputation, collaborate, and settle payments across platforms. Ethereum has introduced ERC-8004, a new technical standard developed by the Ethereum Foundation’s dAI Team in collaboration with MetaMask, Google, Coinbase, and other organizations. The standard provides infrastructure enabling AI agents to locate each other, evaluate reputations, request and compensate for services, and verify completed work through blockchain-based systems. ERC-8004 uses three onchain registries providing agents with verifiable identity and reputation histories stored on Ethereum. The identity registry contains agent names, skills, and endpoints. The reputation registry maintains an immutable record of feedback belonging to each agent. The validation registry records proof that the agent’s work was completed correctly. Ethereum is for AI. ERC-8004, a new standard by the @ethereumfndn dAI Team, @MetaMask, @Google, @Coinbase, and others, provides a blueprint for how AI agents find and review each other, request and pay for jobs, and verify the work done. What builders need to know. — Ethereum (@ethereum) February 4, 2026 Registry System Enables Cross-Platform Portability The three-registry architecture makes agent trust portable across different tools and platforms. Builders can access an agent’s established history without requiring reputation construction from scratch on every application or marketplace where the agent operates. For developers, this means a five-star agent history functions as an accessible asset across tools and platforms. Agents enter an open, universal directory searchable across organizations, making it easier for developers to find, test, and integrate AI services into their technology stacks. The standard also supports agentic communication protocols such as A2A and MCP, as well as payment protocols such as x402. They will enable AI agents to find specialized counterparts, check reputation before interaction, delegate work…
