Unlike COVID-19, Web3 and Web 3.0 are fundamentally different. Web3 is blockchain-based version of the internet while Web 3.0 is what we would consider an upgraded concept of the internet that we currently use, Web 2.0.
Created by Ethereum co-founder Gavin Wood, Web3 is meant to combat the stranglehold that giants such as Amazon and Google have over the internet world today. Web3 is more concerned about returning the power to users and creators through blockchain, cryptocurrency, and NFTs rather than solving issues around asset ownership.
Web 3.0, on the other hand, was proposed by Tim Berners-Lee, the inventor of the World Wide Web. The semantic web is a major component of Web 3.0 and aims to make information more accessible by storing all data in one place, the Solid pod. This will allow users to control who or what applications have access to their data, instead of having our personal information taken and circulated by tech giants today.
