Which Blockchain Will AI Choose?

The podcast explores the integration of AI agents with blockchain technology, particularly focusing on Ethereum and its layer 2 solution, Base, as well as Solana for their low transaction costs. Davide Krapis from the Ethereum Foundation discusses the significance of Ethereum for AI coordination, drawing from his expertise in market design and machine learning. He emphasizes the role of smart contracts in enhancing AI coordination and the necessity for Ethereum to utilize its scalability for data verification.

Concerns in the AI field, such as resignations at Anthropic and ethical implications of AI behavior, are also addressed. The hosts advocate for sustainable yield in DeFi, introducing initiatives like KPK's non-custodial vaults and Main Street's delta-neutral strategy to improve the DeFi landscape. The importance of cryptography and security in asset protection is highlighted, with Ethereum evolving towards post-quantum security.

The discussion includes the potential for AI agents to create their own blockchain and design better protocols, while the DIA team aims to enhance Ethereum's usability for AI. The emergence of serious teams focused on AI agents on Ethereum marks a shift from experimental projects to legitimate infrastructure development. The introduction of the ERC 8004 standard is significant for standardizing agent identity and reputation, facilitating agent-to-agent commerce.

Key components for agent-to-agent commerce are identified as payments, discovery, and trust, with the new payment protocol X.402 addressing payments and ERC 8004 focusing on discovery and trust. The identity registry for ERC 8004 functions like a passport, allowing agents to connect relevant information for services. Current trends in AI, particularly with platforms like OpenClaw, are noted, with expectations for improvements in the future.

The conversation emphasizes Ethereum's role as a leading platform for AI agents, transitioning to a robust infrastructure with established standards. The development of zero-knowledge protocols on Ethereum is crucial for managing AI transaction stakes, while neutrality and censorship resistance are essential for future agent interactions. Short-term priorities for Ethereum include improving scalability, maintaining low fees, and enhancing security.

The complexities of agent economies are discussed, highlighting the need to eliminate human bottlenecks for efficiency. The potential for autonomous organizations and economies, as well as the development of generalist robots, is speculated upon. Privacy in AI interactions is a key topic, with Ethereum recognized for its leadership in privacy technology.

The potential for AI agents to enhance user interfaces on Ethereum is discussed, particularly in streamlining transaction processes. Excitement for 2026 is expressed, focusing on the adoption of technologies like the X4.02 payment protocol and ERC-8004, while encouraging builders to engage with ongoing projects. The conversation concludes with anticipation for future advancements in AI and Ethereum.
