Web 3.0 is a concept that refers to a new generation of decentralized applications on the Internet, without intermediaries or central authorities, as is usually the case.
Instead, Web 3.0 uses technologies such as blockchain, cryptography and point-to-point networks to guarantee the security, transparency and autonomy of users and data.
This new Internet promises a more democratic, inclusive and participatory online world, where users can control their own data, identity, resources and collaborate in self-managed communities.
In addition, it is also one of the technologies behind the Internet of Things - IoT and allows creating decentralized applications, running on blockchain.
The applications are similar to any other applications that we use on smartphones and computers, with the difference that they are based on blockchain infrastructure to give more control, autonomy and transparency to users, instead of being completely controlled by large technology companies.
More Security
Another promise of Web3.0 is to increase Internet security, as it is based on blockchain - with this technology, all activities will have to be signed with a private key.
In theory, this could solve one of the problems with the current structure of the Internet: the fact that there is no control over where data is stored.
For example, when using a cloud storage service, we don't know where the data is stored and who has access to it. With Web3.0, the user can choose where the data will be recorded, who should have access and for how long.
Reality or Utopia?
Despite all these promises, Web3.0 is nothing more than a utopia for many people. If we look at the issue of Apps, the APIs used are mainly developed by two companies and the cryptocurrency exchanges are dominated by four world-class companies.
Another difficulty faced by the transition from a centralized to a decentralized model is that of regulation. According to several jurists, the decentralization of the Internet could lead to a huge increase in cybercrime, hate crimes or online harassment.
