What Is Web 3.0?

Imagine a new kind of Internet that accurately translates what you type and understands what you say, whether through text, voice, or other media, and where all of the content you consume is more personalized than ever before. In the evolution of the Internet, you are about to enter a new era. It's been termed Web 3.0.

But, exactly what is Web 3.0, how will it look, and how will it affect our lives? If you’re curious to know the above, you have reached the right place. In this tutorial, you will get all the answers to your questions related to Web 3.0. 

What Is Web 3.0?

• Web 3.0 is the internet's future generation, in which websites and apps will be able to comprehend data in a human-like manner.
• The main concepts of Web 3.0 include decentralization, openness, and better user utility.
• To create a more intelligent, autonomous, and open internet, Tim Berners-Lee, the inventor of the World Wide Web, termed Web 3.0 the Semantic Web.

The Difference Between Web 1.0, Web 2.0, Web 3.0

Web 1.0	Web 2.0	Web 3.0
Despite only providing limited information and little to no user interaction, it was the first and most reliable internet in the 1990s.	Because of developments in web technologies such as Javascript, HTML5, CSS3, etc., and Web 2.0 made the internet a lot more interactive.	Web 3.0 is the next break in the evolution of the Internet, allowing it to understand data in a human-like manner.
Before, there was no such thing as user pages or just commenting on articles.	Social networks and user-generated content production have flourished because data can now be distributed and shared.	It will use AI technology, Machine Learning, and Blockchain to provide users with smart applications.
Consumers struggled to locate valuable information in Online 1.0 since there were no algorithms to scan through websites.	Many web inventors, including the above-mentioned Jeffrey Zeldman, pioneered the set of technologies used in this internet era.	This will enable the intelligent creation and distribution of highly tailored content to every internet user.

Features of Web 3.0

• Open - It's 'open' because It was built in full view of the public using open-source software created by a community of developers who are open and accessible.
• Trustless - Users can engage openly and privately without the risk of an intermediary, resulting in "trustless" data.
• Permissionless - Without the necessity for approval from a controlling organization, everyone, including users and providers, can participate.
• Ubiquitous - Web 3.0 will allow us to access the Internet from any location. Web-connected gadgets will, at some time, no longer be limited to PCs and cellphones, as they were in web 2.0.

Layers of Web 3.0

Web 3.0 is propelled by four new layers of technological innovation:

1. Edge Computing - While web 2.0 changed currently commoditized personal computer technology in data centers, web 3.0 pushes the data center out to the edge (i.e. edge computing) and into our hands.
2. Decentralized Data Network - Users will own their data on web 3.0 since data is decentralized. Different data generators can sell or share their data without losing ownership or relying on intermediaries using decentralized data networks.  
3. Artificial Intelligence and Machine Learning - Artificial intelligence and machine learning algorithms have advanced to the level that they can now make useful and occasionally life-saving predictions and acts.  
4. Blockchain - Blockchain is a decentralized technology that uses smart contracts to execute transactions. These smart contracts define the semantics of a web 3.0 application. As a result, everyone who wants to develop a blockchain application must use the shared state machine.

How Does Web 3.0 Work?

• Web 3.0's goal is to make Internet searches much faster, easier, and more efficient, allowing even complex search terms to be handled rapidly.
• In a Web 2.0 app, a user interacts with the frontend, which communicates with the backend, which then communicates with the database. Consumers receive the whole code via a web browser after it is saved on centralized servers. 

Web 3.0 doesn't consist of centralized databases that store the state of the application nor a centralized web server where backend logic can reside. Instead, there is a blockchain to build apps on a decentralized state machine and maintained by anonymous nodes on the web.

• Smart contracts, created by developers, describe the logic of your apps and are put onto the decentralized state machine:

• This shared state machine is used by anyone who wants to construct a blockchain application. The front end is nearly identical to that of web 2.0.

Advantages and Disadvantages of Web 3.0

Advantages - 

• In terms of data security, end-users will benefit the most from data encryption.
• Due to decentralized data storage, users will be able to access data in any situation. Users will receive multiple backups that will aid them if the server crashes.
• Most blockchain systems are developed by non-profits, which provides an open-source blockchain platform that allows for collaborative design and development.
• The data will be provided from any location and on any device.
• Web 3.0 is useful for problem-solving and heavy knowledge-generation tasks.

Disadvantages - 

• To make the technology accessible to more people worldwide, the devices' capabilities and qualities will need to be expanded.
• Any websites built on web 1.0 technology will become obsolete once web 3.0 is fully implemented on the Internet.
• Web 3.0 technology is more intelligent, efficient, and accessible than in previous generations. However, the technology isn't quite ready for general use.
• With easier access to a user's information and reduced privacy thanks to web 3.0, reputation management will be more important than ever.
