Justin Sun posted more than a dozen tweets in a row. What is the background of the newly launched http:/b.ai? On the surface, http:/b.ai is an "AI transfer station". Anonymous access is available with just one API key. The entire Claude + GPT + Gemini + domestically produced large-scale model series has moved its payment and settlement processes on-chain, but this is just the tip of the iceberg; the real ambition lies here. http:/b.ai Two things need to be sent to each AI Agent: 1. ID card (8004 frame) Each Agent has an independent on-chain address that records behavior, reputation, and credentials. Agents can verify each other without needing to be linked to any human account. 2. Bank card (x402 protocol) Based on x402, the agent can automatically make payments, purchase computing power, call APIs, and pay other agents—all at machine speed, 24/7. In other words— Previously: AI would do the work for people, but it would require your account and your credit card. http:/b.ai Afterwards: AI has its own identity, its own wallet, and it pays on the blockchain. Humans have quietly transformed from "AI's master" into bystanders. The ideal is good, but what about reality? 1. The track is already occupied. The AI ​​transfer station business is already mature, with a complete developer ecosystem. http:/b.ai What makes them stand out in attracting users? 2. Compliance Threatens: Anonymous access and resale of API quotas are explicitly prohibited by OpenAI/Anthropic's ToS. Platforms can block upstream keys at any time, making the supply side unstable. 3. The AI ​​Agent Economy is still in the PowerPoint stage. The x402 protocol and the 8004 identity framework sound sexy, but currently, the actual AI agents running on them have almost zero infrastructure. Where are the users? Could you please answer, Brother Sun? @justinsuntron twitter.com/followin_io_zh/sta...
