Many of Web3's advantages stem from its decentralised structure, which shifts control of the internet from big tech companies to those who use it. For example, internet users on Web 2.0 must log in to social networks to access, share, or interact with a lot of content. The platform ultimately controls who can join and how they interact with others. It can remove users or limit what they can do on the platform. Web3 gives this control to the community, which can then self-govern the content and the people sharing it. In addition, a decentralised internet comes with the following benefits:



‎Interaction: Users should have more opportunities to interact with content and other users in Web3 and experience higher engagement levels than with Web 2.0 and 1.0 websites and platforms.



‎Ownership: Web3 users are more than content consumers. They are owners of the community who receive incentives for participation instead of being asked to trade their personal data to access platforms.



‎Permissions: All network users have access to the network's data and permission to use the service.



‎Privacy: In Web3, your identity links to your digital wallet. What you do online is open to the public, but you can keep your identity a secret.



‎Speed: The use of artificial intelligence, machine learning, and smart contracts via the blockchain makes it possible to get more relevant data to end users in less time.

Disadvantages of Web3

While Web3 offers promising advancements in decentralised technology, increased privacy, and user control, you should be aware of the challenges and drawbacks associated with its adoption. Understanding the disadvantages below can help users and businesses make informed decisions about integrating Web3 into their operations.



Cost: Blockchain technology is expensive and requires considerable energy to operate. This applies to Web3, which operates on this technology.



Hardware: Users may need to invest in newer equipment to access the full benefits of Web3 platforms and applications. Older devices may need more memory or capability.



Regulation: Decentralisation turns the responsibility of regulating content and user actions over to the public. This can create spaces for questionable content to appear online, leaving users of autonomous organisations to govern themselves.



Scalability: Using blockchain to process transactions in a peer-to-peer network requires considerable computing power that currently needs to be more scalable. This lack of scale increases costs and restricts who can participate, which leads to centralisation by default.
