This is a simplified definition, which is not needed for this course. Web 3.0 is the next generation of the internet, where websites and apps will be able to process information in a smart, human-like way. This version of the internet is built on new technology like blockchain, which allows for more security, privacy, and decentralization (meaning not controlled by just one company or organization). In simple terms, Web 3.0 aims to create a more intelligent, connected, and open internet.
