We can make a hypothesis that Ethereum's current performance can be infinite. Can Ethereum solve real-world problems? The answer is denial. The reason is that: Ethereum is a closed system formed based on formal logic. In this system, it is impossible to send any real objects from the real world into this closed system. At this point, some people may argue that these oracle machines can use ChainLink to RWA real-world data onto Ethereum, a closed platform. The answer is: no. Centralized oracle machines like Chainlink can only simulate and approximate real-world data into Ethereum, a closed formal system platform. Instead of integrating real data with the Ethereum platform. The logic behind this operation is simply to treat Ethereum as a tool platform, which differs only from AWS and Alibaba Cloud in transparency. It can solve the problem of opacity in AWS cloud. It cannot solve any other problems.
