After the crayfish became popular, I increasingly believe that in the near future, various AI agents will replace their owners and be active on the internet for communication, trading information, shopping, and other behaviors. And the most fundamental one among them is payment. The payment in the AI Agent world needs to meet the requirements 1) Fast enough to support high-frequency transaction transfers 2) Extremely low transaction fees support small amount transfers (even below 0.0001 USD) 3) Without borders It is obvious that only blockchain can meet the above conditions. In the era of agents, blockchain and AI are truly a perfect match. Seeing the HSK White Paper 2.0 just released by Mr. Xiao, it is obvious that this is also the main focus. Providing a comprehensive payment network for agents is the most promising direction for web3. In addition to the priorities mentioned earlier, I found that Mr. Xiao is also considering more deeply. Hashkey Chain also uses zero knowledge proof, which can give the agent a compliant digital ID card, which not only has privacy protection functions. More importantly, it can solve a large part of security issues. Eliminate high asset agents from being tracked and pursued by bad actors. Hashkey Chain has also designed an institutional level license chain, leveraging its compliance advantages. It can serve as the main chain for settlement, while institutions can build an execution layer to achieve throughput of millions of transactions per second. Anyway, AI is not stealing the limelight from blockchain, but it needs blockchain even more, and this direction is becoming increasingly interesting.
