Web3 (2020+) is read, write, and own. People create, consume, and own the upside of their work through tokens. Web3 is built on peer-to-peer networks of computers that talk to each other without middlemen.
Web3 identity solutions center around user-centric ownership models. They also prioritize portability, with solutions promising a foundational identity layer that enables inherent information transferability, rather than retroactively fitted portability solutions as in web2.
