Definition | Web3 – Web 3.0

First, there was web1, andInternet Which we all know and love. Then there was the user-generated Web 2, which heralded the arrival of social media and blogging. today on social networksPeople are talking about web3 (or web 3.0), the internet’s supposed next big leap forward. But what exactly is it? Web3 is currently in development and has yet to be fully defined. However, the underlying principle is that it will be decentralized rather than controlled by governments and corporations as is the case with the current Internet, and to some extent, will be linked to ” metaverse “.

Web3 and the Semantic Web

To avoid confusion, it should be noted that until a few years ago, the term ‘Web 3.0’ was frequently used to describe what is now known as ‘Web 3.0’. Semantic Web It was a concept he proposed father of the internet “,” Tim Berners-LeeInternet from machine to machine. However, Berners-Lee’s concepts are part, but not all, of what we now call Web 3.

Web3, a decentralized network

Today, all the infrastructure of popular dating sites and places where we spend time on the Internet is generally owned by companies and governed to some extent by regulations set by governments. This is because it was the easiest way to build a file network infrastructure : Someone is paying to install and install servers software People want to access it online and then either charge for it or let them use it for free, as long as its rules are followed.

Today there are other options, in particular technology blockchain. The blockchain It is a relatively new method of storing data over the Internet, which revolves around two basic concepts: encryption and distributed computing.

  • The encryption It means that data stored on the blockchain can only be viewed by people who have permission to do so, even if it is stored on the computer Owned by someone else, such as a government or corporation.
  • Distributed computing means that a file is shared among many computers or servers. If a particular copy of a file does not match all other copies, the data in that file is invalid. This adds another layer of protection, meaning that no one other than the person controlling the data can access or modify it without permission from the person who owns it or the entire distributed network.

Together, these concepts mean that data can be stored in such a way that it is never under the control of the person who owns it, even if it is stored on a server owned by a company or under the control of a local administration. The data cannot be accessed or modified by the owner or government without keys encryption Which proves that he is the owner. And even if its server shuts down or deletes it, the data can still be accessed on one of the many other computers on which it is stored.

The role of the metaverse in Web3

The last important concept of Web 3 we need to cover is metaverse. With respect to web3, the term ” metaverse Denotes the next iteration of the web frontend (end of introduction) : me’user interface Through it we interact with the online world, communicate with other users and deal with data.

The idea of ​​the metaverse is that it will be a more immersive, social, and sustainable version of the Internet as we know it. You will use techniques like Virtual Reality and Augmented Reality To allow us to interact with the domain Digital In a more natural and immersive way. For example, using virtual hands To understand and manipulate things, and our voices to give instructions to machines or talk to other people.

In many ways, the metaverse can be thought of as the interface through which humans interact with tools and apps from web3. It is possible to build web3 applications without including the metaverse: Bitcoin He is an example. The technology and expertise of the Metaverse will play an important role in how many of these applications interact with our lives.
