Using blockchain as the underlying architecture, Web3 aims at providing user-centric intelligent services to bring the ownership of digital assets back to the users. Instead of having a central middleman such as a bank or a tech company, every user can exchange money and information on the web. With a single personalized account, users would theoretically be able to move seamlessly from social media to gaming to shopping with a public record of these activities on the blockchain. Furthermore, everyone can become a part of the blockchain and get incentives with cryptocurrencies for helping to develop and maintain the service.
