It makes data transparent and tamper-proof.

In the world of Web2, applications acquire user data by offering free services and then monopolize that data to make profits and build their own businesses. The data is stored on their central server and cannot be accessed by the outside world. There is no way of knowing what data is stored, and with what manner and granularity. Furthermore, if these applications are compromised or actively terminate their service, users' data will be lost overnight. However, with blockchain technology as the underlying Web3 framework, the data on the chain is open, transparent, and non-tamperable, realizing the independence and security of users.

Break down data silos and improve interoperability.

With Web2, users have to go through a registration process every time they use a new application. This is because each application has its own separate database and cannot connect to other applications.
