Since Web 3.0 is built on cryptographic primitives and often features open source code, anyone can contribute to the project by reviewing code. This boosts security for users and turns transparency into a competitive advantage.
Web 3.0 also re-balances power dynamics between users and platforms, putting users in control of their data.
In Web 3.0, users can also own their platforms, often coordinated through tokens. As they benefit directly through the growth of the platforms, they have the incentive to provide critical services like moderation, for example.
Web 3.0 evolves the internet to take the good from its predecessor and improve upon it through aligning economics and incentives amongst all users — and thus avoid the negative effects of ad-supported models.
