Trustless Agent Day has become the most prominent focus of Devconnect ARG. I have reviewed the entire event and attempted to understand the new trends of ERC-8004 and x402 from multiple perspectives. This event is jointly initiated by core developer communities such as Ethereum Foundation (EF), Coinbase, MetaMask, etc. Its high specifications and hardcore topic signify that the combination of Web3 and AI has officially entered a new stage of "standardized infrastructure" from conceptual hype. The vision of the event is very clear: to end the era of AI agents being just API wrappers, and to build a true intelligent agent economy that does not require licenses, is interoperable, and comes with payment capabilities through ERC-8004 and x402 protocols. Here are some core insights extracted from these speeches and roundtables: one ️⃣ Two pillars established: AI's "passport" and "bank card" The consensus has been formed that the infrastructure of the Agent economy lies in resolving identity and payment frictions. X402 (Payment): The ultimate solution known as "Killing API Keys". Revitalize the HTTP 402 status code, so that the agent can access global resources only by signing the wallet, and change the stable currency into the "measurement unit" of the Internet. ERC-8004 (Identity): Granting Agent on chain identity, discovery mechanism, and verifiable reputation. This is a prerequisite for establishing trust and conducting high-frequency transactions between agents. two ️⃣ Searching for PMF: From "making shovels" to "digging gold" The infrastructure construction period has been basically completed, and now we must enter the application explosion period. Breaking point: "Gamification" and "micro payments" are considered important means. By predicting the market or high-frequency games through Babylon and other methods, agents can accumulate real economic decision-making data in low-risk environments. three ️⃣ The Elephant in the Room: Farewell to LARPing Sharp criticism of the current situation erupted on site. Eliza's founder bluntly stated that many agents are actually "LARPing" (role-playing) - they do not have reasoning and decision-making abilities, but only execute preset scripts. Conclusion: A true agent needs to be trained on real-world distributed data, rather than just existing as a chatbot. four ️⃣ Vitalik's philosophy: 'Privacy is hygiene' During the fireplace conversation, Vitalik put forward a profound viewpoint: 「Privacy is not a feature, privacy is a hygiene.」 Privacy is not a feature added to increase selling points, but a basic hygiene that must be done to prevent data leakage. Computational sovereignty: Communities exhibit a strong 'Local First' bias. The future agents should not be puppets of cloud black boxes, but rather digital twins that run locally and are loyal to user interests. Summarizing Trustless Agent Day, we announce a new narrative for the Agent race: we are shifting from simply calling big models to building a chain based intelligent agent society with independent economic sovereignty, trustworthiness, and interconnectivity.
