- Ethereum developers advance protocols that integrate Artificial Intelligence agents on the blockchain.
- A new standard, ERC-8004, registers AI agents using NFTs, enabling decentralised identification and collaboration.
- Coinbase and Cloudflare are launching a foundation to support a protocol for crypto payments on websites and APIs.
- Feedback and review mechanisms are built into the system, with options ranging from public reviews to cryptographic checks.
- The initiatives seek to reduce large tech firms’ dominance over the AI and digital economy.
Developers in the Ethereum community are building new technologies to allow artificial intelligence (AI) agents to operate directly on the blockchain. In recent months, teams have released major updates to open protocols that give AI-powered bots the ability to interact, verify, and transact with each other without relying on centralised platforms.
Last month, the Ethereum Foundation launched the dAI team to promote Ethereum as a key infrastructure for “agents”—AI-driven bots used for tasks such as shopping or managing money. Soon after, Coinbase and Cloudflare announced a foundation to promote x402, a protocol designed to make it easier for websites and API services to receive crypto payments.
The dAI group, along with ConsenSys, the company behind MetaMask, released the final version of ERC-8004, a protocol that issues each AI agent an NFT. This NFT serves as the agent’s on-chain identity and links to a public registry showing names, skills, and contact points for each AI agent. “Very soon, many of the services that we will buy and sell as consumers and producers will be intermediated by AIs,” said Marco de Rossi, AI lead at MetaMask.
Users and agents can rate each other through this standard, much like leaving product reviews, but also through more technical proofs if needed. “In your example with Amazon, Amazon is the owner of information. They can censor [reviewers]. They can remove them. While here, all the signals are public,” de Rossi explained. For more complex assignments, feedback could be verified by validators who confirm whether agents performed their tasks correctly before results are accepted.
Growth in the AI sector now outpaces U.S. consumer spending, according to recent data, leading developers to look for ways to limit the power of large centralised AI companies. De Rossi said, “Large centralised AI players that control economies — that would be a very strong menace … to free markets and democracies.”
The move towards decentralisation is aimed at allowing both people and AI agents to openly participate and interact in the online economy, without needing approval from large tech gatekeepers.
