Web3

Web3’s defining feature is ownership. Whereas the first iteration of the commercial internet (Web1) was read-only for most users, and Web2 allowed users to both read & write on centralized platforms (Twitter, Facebook, YouTube, etc), Web3 gives users full ownership over their content, data, and assets via blockchains. It empowers users to read-write-own.
