No "characteristics" is a fundamental part of the design philosophy of Ethereum. Instead, Ethereum provides an internal Turing complete scripting language for users to build any smart contract or transaction type that can be accurately defined. To build a full-scale Daemon or Skynet, you may need thousands of interlocking contracts and be sure to feed them generously. Anything is possible.

It's still not the innovation of technology, but the innovation of ideas, which will guide the development and application of technology. After web3.0, a new kingdom will be born. This kingdom is no longer divided by regions and boundaries, but a kingdom where interests, languages, themes, occupations and specialties are gathered and managed. When the time comes, it can really be said that "the emperor will take turns doing it and come to my house next year". You will have the opportunity to build a new Internet kingdom and become a king, or you may become a president in the democratic election of the Internet kingdom. By then, you will have network citizens from all corners of the earth.
