Web3 is an upgrade planning to Web2, where people interactions will be like in real world. There are lands, buildings, markets, banks, schools to be visited like in the real world in Web3. Visiting Web3 will be like visiting a real building. People appearances are represented in the form of avatars, just like Namescon event a view years ago, where people can great each other in a form of avatar to avatar. The address in Web3 is a block in blockchain, not IP address. Web3 domains will be needed to mask block address in blockchain, just like domain name masking IP address in internet.
The question is only, when Metaverse will be available for daily use? It is still in development stage, and long way waiting.
