Ethereum's ERC-8004: A New Trust Layer for AI Agents

Davide Crapis, head of AI at Ethereum Foundation (EF), has revealed the network's new strategic direction: rather than attempting to run neural network computations on-chain, Ethereum will focus on becoming an independent verification and coordination environment for autonomous AI programs. Crapis shared the vision during a CoinDesk interview at NEARCON 2026.

Why This Matters

The rapid proliferation of artificial intelligence systems threatens to re-centralize internet infrastructure around a handful of tech giants. According to Crapis, this directly undermines the core values of the crypto industry — user sovereignty, privacy, and censorship resistance. Ethereum has no intention of competing with OpenAI or Google in building language models. Instead, the development team aims to prevent corporations from monopolizing the next technological layer.

The EF strategy is split into two key pillars: decentralized coordination of AI agents and user data protection.

Decentralized AI Agent Coordination

Autonomous programs — commonly called agents — need infrastructure for identity, payment exchange, and reputation building. Under the EF's plan, compute-heavy operations will remain off-chain on traditional servers. Ethereum itself will serve as a public registry with no single point of control, enabling agents to discover one another and settle transactions.

Crapis compared the envisioned system to a decentralized version of Google Reviews with built-in payments. To bring this mechanism to life, the team is standardizing an AI agent identity protocol called ERC-8004. According to Crapis, the technology is already gaining traction beyond the Ethereum ecosystem.

Props AI and Local Data Processing

The second strategic pillar operates under the working title Props AI. The problem it addresses is the mass data harvesting conducted by centralized AI services, which build detailed user profiles based on queries.

The alternative approach involves processing data directly on users' devices, bypassing third-party servers entirely. This is designed to eliminate surveillance risks and personal data leaks.

Cryptographic Keys to Replace Passwords

Crapis also raised concerns about escalating cybersecurity threats. Neural networks are becoming capable of convincingly impersonating humans, rendering traditional passwords ineffective. The foundation for a new security paradigm, he argued, should be cryptographic keys that can be mathematically verified.

AI integration has become one of Ethereum Foundation's top priorities. The team acknowledges that algorithms will define the network's next evolutionary phase and is working to position the blockchain as a foundational layer for smart agent operations. Earlier in February, project co-founder Vitalik Buterin published a detailed analysis of potential synergy scenarios between Ethereum and artificial intelligence.
