The World Wide Web abbreviated as "WWW" started with the first version popularly known as Web 1.0. This web technology is usually referred to as a read-only web – where there's no interaction on the internet.
Due to this, an innovation of the internet sprung up which enables internet users to interact and engage with content they consume online, and also socialize with other people in different regions.
It's referred to as a "read and write" web, and it's called "web 2.0". The next iteration of the internet is "Web 3.0", which is expected to transform the internet and improve on some issues that exist in "web 2.0".
In this guide, I'll walk you through the true meaning and concept of Web 2.0 and Web 3.0.
What is Web 2.0?
Web 2 is the second phase of the internet, and of course, the current web we are using. It was developed to evolve the previous web technology — Web 1.0.
The first version of the web doesn't foster interaction and engagement between users and content, thus – web 2.0 enables it by employing different modern web languages such as HTML, CSS, Javascript, etc.
It enables users to read, as well as create information online. It also allows contributors, which can also be referred to as "content creators" to earn from their work through advertising-driven revenue generated by the tech firms.
Examples of Web 2.0 applications are the tools we usually use in recent days, including Meta (previously known as Facebook), Google (now Alphabet), Amazon, Twitter, etc.
What Is Web 3.0?
Web 3.0 poses a new revolution of the internet as it brings advancement to the web and also solves the issue raised in web 2.0.
The major concept is to create a decentralized web that will give power back to internet users through the utilization or integration of blockchain.
Web 3.0 is considered a "read-write-own" web — meaning you can read and write on the internet, the "own" aspect signifies ownership of anything you created on the internet.
It's powered by blockchain technology to enhance transparency and privacy – whereby users only control who can have access to their details.
What is the Difference Between Web2 And Web3?
It's important to grasp the difference between Web2 and Web3 to understand the potential of the new web technology.
Some of the components of web3 that make it different from Web2 are:
1. Decentralization
In web2, what users created are stored in a single central place, thus controlled by the company that hosts them. While in web3, anything created by users such as content; is shared and distributed amongst the network; there's no central authority controlling them.
2. Permissionless
You can be denied permission to do certain things in web2 applications whether because you're from a certain region or your age. And also, for you to start using some of these applications, you have to seek permission through personal details submission and others. Web3 allows you to use the internet and perform any activity without any permission, irrespective of your age, region, etc, thus it's permissionless.
3. Trustless
In the current web technology, users rely heavily on big firms and they trust their data on them because these companies can outrightly do anything to their data either by selling – as it's in their custody. In web3, users don't trust their data with any central authority or third party.
Conclusion
Web3 has posed to be the next generation of the internet, however, the true concept is yet to be fully achieved, and thus many of the web3 products are still facilitated by the web2 platforms. It's still new and needs more development to scale and be fully adopted by the masses.
