Ethereum is preparing to launch the ERC-8004 standard on its mainnet, introducing a new protocol that enables AI agents to interact across organisations with portable, verifiable reputations. The launch is seen as a step toward building a decentralised infrastructure where autonomous software can operate safely, reliably, and without relying on centralised intermediaries.
The ERC‑8004 standard creates a framework for persistent identities and reputation tracking on the Ethereum blockchain. Each AI agent receives a unique on-chain identifier, which links to metadata describing its capabilities, endpoints, and credentials. Coupled with a reputation registry, this allows AI agents to carry a verified record of past performance, making it easier for other agents or organisations to trust them before initiating interactions or transactions.
One of the key features of ERC‑8004 is its validation mechanism. This allows developers and organisations to verify that agents have completed tasks as claimed. By providing a transparent, tamper-proof record of performance, the standard ensures that AI actions are accountable and auditable, even in scenarios where agents are working independently across multiple platforms or organisations. This solves one of the biggest challenges in deploying autonomous AI at scale: trust.
With ERC‑8004, Ethereum developers aim to create a trustless agent economy. AI agents could coordinate on complex projects, share verified outcomes, or even execute autonomous transactions with minimal human supervision. The standard is expected to accelerate the development of cross-platform AI applications, decentralised finance systems, prediction markets, and other ecosystems where multiple autonomous agents need to interact reliably and transparently.
Experts say the timing of the ERC‑8004 rollout is critical. As AI systems become more integrated into production workflows, they increasingly handle payments, data exchange, and decision-making in real time. Existing trust models designed for human interactions often fail to scale in such autonomous environments. By providing a shared standard for identity, reputation, and verification, Ethereum is positioning itself as the backbone for next-generation decentralised AI infrastructure.
Developers also highlight that the standard can support multi-agent orchestration, allowing AI agents to coordinate their work efficiently. For instance, a development agent could complete a coding task, pass verification to a testing agent, and then transfer verified results to a deployment agent, all while maintaining a verifiable chain of accountability. This opens the door to more complex, automated workflows that could reduce human oversight while increasing reliability and scalability.
With ERC‑8004, Ethereum is not only enhancing blockchain-based AI capabilities but also laying the foundation for a broader interoperable ecosystem of autonomous agents. By standardising identity and reputation on-chain, the network aims to enable AI systems to work across organisations, platforms, and industries in a secure and trusted manner.
