# Web2.0 <-> Web3

In the transition from Web2.0 to ***Web3***, while it's possible to envision the blossoming development of various applications, such as the Metaverse, Virtual Reality, and Cryptocurrencies, these often encounter problems.

These challenges often arise from hardware's performance limitations and costs, making it difficult to provide end-users with a decent user experience. Additionally, the goal of Web3 can be obstructed by current legal frameworks, social structures, and the influence of capitalism.

However, before diving deeper into these, the primary focus should be on ***Data***. Specifically, it's crucial that everyone can take control of their data and information, decide what information to share, and search the information they desire.

This emphasis doesn't only come from the Decentralization idea of Web3. It's also due to the continuous expansion of integrations and services among information systems.

As the volume of data across all systems grows exponentially, it becomes crucial to determine how data is utilized and managed. This allows everyone to collaboratively share the responsibilities and rights of data governance, thus grounding the true concepts of Web3.

For instance, the Metaverse spanning entities like Meta, Google, and Amazon requires cross-system user identity data exchanges, and it becomes doable to allow the end-user to use item from entity A in entity B. Moreover, Virtual Reality and other Cryptocurrency applications demand a certain level of data protection and data consistency assurance.

Web3, especially for ***Data*** aspect, allows people to create their own net/web communities with their own rules, without worrying about data leaks and fraud, while also keeping some level of privacy.
