Since Web 2.0 became important, many companies have wanted and claimed to create Web 3.0. The label has mainly been artificial. For example, the semantic web has been a candidate for this role, but we haven’t really seen it or what it might mean in practice. Now we again have a strong candidate for this role: a blockchain-based distributed web.
Web 2.0 means especially more interactive web services, user generated content and social media.
