What is Web3?

Web3 vs Web2

The term Web3 is commonly used to refer to software that is partly or fully deployed on a public, permissionless blockchain—as opposed to Web2, for traditional server-client web applications. Though it's largely how blockchain software is referred to, Web3 is a marketing term that may give off the wrong impression that it's a new version of the web and that smart contracts are meant to replace all web applications. Web3 is just a better way to control access and process payments.
