What is Web 3? Web 3 will revolutionize the web world with a decentralized Internet focus. On Web 3, users will take full control of their information.
You may have heard about Web 3.0 and its impact on internet transformation. Web 3 is a new pattern of web interaction that will bring about fundamental changes in the development and construction of websites. Simply put, Web 3 can be considered a new phase of Internet evolution.
Computer scientists and Internet experts believe that web 3.0 changes will make the Internet smarter and make life easier. To understand this paradigm shift, we first take a look at the evolution of the Internet.
Web 1
It’s hard for the younger generation to imagine an Internet without Google,Facebook or Instagram stories, but the classic internet era began like this and continued from the mid-1990s to the early 2000s. At the time, people knew the Internet by its original name, “World Wide Web” or “Net”. Users could not share their images or, for example, make a blog about flat earth conspiracy theories. At that time, most content was produced by businesses, newspapers and organizations.
The web 1 era was when people used AltaVista, Netscape or Asked Jeeves to search for images of funny cats instead of Google. Most websites were in read-only format, and users could not upload or comment content. The concept of video streaming didn’t exist either. People used AOL chatrooms for online chat rooms. Downloading a song would take a full day and it would have been necessary to disconnect the phone to connect to the dial-up internet connection.

Web 2
In the early 2000s, the Internet was at a historic point. It could have taken a one-way path and looked like a dull library or become an epic invention that connects everyone from all over the world. Fortunately, he took the second route.
With the advent of social networks, people were able to have an inclusive net experience. Thanks to the web, 2 people were able to upload their images or stream video content on YouTube.
With the end of the first decade of the third millennium, dial-up connections were almost forgotten. Sharing became Trendy World. Online games made it possible for multiple players to interact. Facebook helped connect more people, and Instagram made it possible to upload images from a smartphone.
What is Web 3?
But what exactly is Web 3? In general, Web Three is known as the third and newest phase of Internet evolution. Almost every 10 years, the Internet enters a new phase. On the other hand, there is no control entity before these phases, or there was no global path to converting Web 1 to Web 2, and these different periods are known based on the content nature of the Internet. Simply put, the three phases of the web can be summarized as follows:
- Web 1: Static
- Web 2: Dynamics
- Web 3: Decentralized
Web 3 is decentralized from dynamic web to web. On Web 3, data is not owned by entities or centralized organizations. In addition, Web 3 focuses on improving backhand capabilities. One of the features of web 3 is the emergence of dApp or decentralized applications.
Web 3 is a new step in the evolution of the Internet that puts web navigation and control in the hands of the user. This distinction is achieved by new technologies such as blockchain that enable network performance as a peer-to-peer system (P2P).
Advances made thanks to Bitcoin and Ethereum and other blockchain-based applications show that users can enter P2P transactions, develop projects on a global scale and fully control their privacy. On Web 3, large data companies and tech giants can no longer do business with users’ private data or monopolize information sources.
How does Web 3 work?
You may have faced an offer to buy similar products when shopping online. In this situation, the website learns from the customer’s behavior and shows him suggestions on the same basis. Web 3 also uses learning mechanisms and similar applications in a refined way. Simply put, the Internet learns from your behavior and rewards you with suggestions for content tailored to your needs, searches and activities.
The wide application of P2P frameworks is one of the main features that distinguishes Web 3 from its older version, Web 2. This aspect applies to all Internet applications. For example:
Instead of using Google Drive or Dropbox to store, distribute and share files, you will use services like Storj, Siacoin, Filecoin or IPFS. You may also use platforms like Status instead of communicating via WhatsApp, Zoom or Skype.
Facebook and Twitter seem eternal, but it won’t be long before we see new forms of social networks like Steemit, Hive or Alaska. Even Google Chrome will give its global priority to browsers like Brave that offer more security.
All alternatives to current services will increase user control over their data and will help improve security protocols, anonymity, and prevent technology organizations from misusing data or fully controlling certain information or services.

dApp and Web Apps 3
In short, dApp or decentralized apps are the backbone of Web 3’s transformation. Web 3 promises decentralized Internet, and this promise can be extended to a variety of applications. Terms like “Web Apps 3,” “Decentralized Apps,” “dApps” or “dApp-Web 3” are synonymous with each other. All of these terms refer to decentralized blockchain applications that are part of Web 3.
But how does web application 3 work? One of the inseparable parts of many dApp-apps or web applications is the Smart Contract 3. People familiar with blockchain technology may have also dealt with the concept of smart contracts. A smart contract is a self-administered software agreement that runs on a blockchain such as an ethereum blockchain. These contracts are automatically executed if a relevant set of conditions are met. In this way, these contracts can be automatically checked and executed between the parties.
The use of smart contracts in dApp-s means that contractual logic can dictate the behavior of applications. In practice, this process reduces the need for a company or a certain person as an intermediary.
What is Web3.js?
When learning about Web 3 and its applications, you may also have heard about Web3.js, but what is Web3.js? Web3 library.js is one of the main libraries of JavaScript that is used in the development of web 3 applications. This library can be used to communicate with the Ethereum blockchain. In fact, Web3.js can be considered as a JavaScript Ethereum API. With the Web3 library.js you can create clients or apps that interact with the Ethereum blockchain. This feature is especially necessary for bridging javascript and Web 3.
As a result, Web3.js can be considered as an intermediary between JavaScript and smart application contracts for Web3 applications. With libraries like Web3.js you can interact with local nodes or remote ethereum. This is possible via http, IPC or WebSocket connection. The reason for the success of the JavaScript Web3 library is.js the support of all browsers. Web3.js is one of the main frameworks used in decentralized application design. If you wish, you can use official JavaScript documentation for the Web3.js Ethereum Javascript API.
Decentralized Internet with IPFS
IPFS stands for Distributed and Peer-to-Peer File Sharing System. IPFS does not have access to the Internet through a central server or URL, but through peers on the IPFS network around the world. Various devices that use IPFS are considered nodes in a large distributed network, allowing access to content from local nodes rather than remote servers. In addition, IPFS uses content addressing, which means not looking for location, but searching for specific content.
IPFS has several advantages for building web3 applications and decentralized applications. For example, it increases internet responsiveness because it does not fetch information from a centralized server and unit. As a result, censoring the Internet or preventing information sharing becomes more difficult. In addition, such a decentralized network can dramatically reduce delays. When you get content from a local node instead of a remote server, the loading time is naturally shortened.
Why do we need Web 3?
There is an increasing need to decentralize the Internet and turn it into a distributed system of computers that communicates directly and securely with each other. In the mid-2010s, large businesses and political organizations used social networking data. Even before the Cambridge Analytica scandal, large industries around the world were dedicated to collecting and exchanging users’ personal data.
Internet users realized that their valuable information was easily accessible to social networking channels, online retailers and entertainment services. Large organizations such as Google, Facebook, Twitter and Amazon today use users’ identity data, search engine data, browsing habits and shopping information to influence users’ online and offline behavior.

Web 3 Benefits
To better understand web three’s performance and its benefits, we offer a list of features and benefits:
Web 3 is decentralized
On Web 3, no central authority is able to control the Internet, and governments or other political organizations cannot block access to the World Wide Web. This network model is based on the Ethereum blockchain, which operates as a system with impenetrable encryption.
Data ownership
When Web3 becomes a reality, large companies like Amazon, Facebook and Google cannot use their massive servers to store users’ data. Instead, Internet users will have complete control over their information, including financial details, login details and other data.
Semantic Metadata
One of the most important components of Web 3 is semantic metadata. With this mechanism, the web is able to understand symbols, keywords, texts and their meaning. For example, the network can understand the old “smiling” emoji made with two dots and a parenthesis and interpret it as a human smile, a sign of happiness or affirmation. This example was just a small example, and the semantic web generally makes communication, transactions and easy exchange of information between entities easy. The semantic web project goes back to the original idea of Berners-Lee (a computer scientist known as the inventor of the World Wide Web) from the Internet. He envisioned the future as a world free from bureaucracy in which intelligent machines automatically carry out time-taking operations.
Artificial Intelligence
Artificial Intelligence(AI)is not a project that was first addressed on Web3. We know that artificial intelligence also exists in Web 2 applications, but AI on Web 3 has a fast learning mechanism. Artificial intelligence distinguishes between good and bad data between real people and robots and, most importantly, between fake news from real reports.
Ultra-secure protocols
All data on Web 3 is decentralized and distributed through the network, which means Internet providers can no longer share users’ data with their activity host countries. Hackers should also shut down the entire network for an attack. Users’ data is encrypted and protected by ultra-secure protocols. This scheme is rooted in cryptocurrency blockchains where traders can enter into financial transactions with full control over their data.

Interoperability
Currently, most applications are operating system-based. Some apps only work on Android, while others only run on Apple devices. The same trend applies to Microsoft Windows apps, Mac software, and more.
On Web 3, applications are neutral about operating systems and devices. For example, the same app can be installed on iPhones, smart TVs and car computers.
Unlicensed networks
Today, The Web 2 is relatively free and accessible in many places, but in some parts of planet Earth it is limited for political reasons and other criteria such as income, gender and even race. Web 3 will be available to everyone at any point thanks to unlicensed blockchains. Cross-border transactions and money transfers will also be possible regardless of the geographical location of those involved in the business.
Non-interference service
Data is stored on Web 3 on multiple distributed nodes. This system ensures that there are always enough backup nodes to supply the chain and prevent server failure. Simply put, the Internet will never be disabled due to server failure.
Virtual 3D Identity
Web 3 will open the door to new methods of communication and virtual interaction. Chatting, emailing and video calling will still be possible, but users can access the virtual identity that is provided on the web. These virtual avatars represent individuals in business transactions, job collaborations and appointment applications such as online game characters.
Inclusive presence
When Web 1 was released, you could only access the Internet from remote locations such as a home computer or a device in an internet café. With Web 2, the Internet was quickly transferred to smartphones, tablets and other portable smart devices.
But Web 3 will be available everywhere and its implementation will encompass all aspects of everyday life. Web 3 can be implemented on more devices, an invisible network of information, communication protocols and transaction mechanisms that will be available in all parts of planet Earth.
Web 3 Challenges
Like any new technology, Web 3 is not easy to implement at least at the beginning. Some of the challenges and disadvantages of web3 are:
Human mismanagement
Web 3 is a revolutionary step in the evolution of technology, and its publication can divide our relationships on the Internet before and after Web3, but it should not be forgotten that people with evil intentions always exist. Users with malicious intentions can publish false and misleading information on Web 3 and pave the way for online crimes. On the other hand, AI and cryptographic learning mechanisms evolve and update quickly to reduce the number of hacking attacks.
Infinity Web 2
Realizing the promise of a fully semantic web may take some time. In the current situation, Web 2 hosts more than 1.5 billion websites, thus exploring artificial intelligence in all this information and communicating with the concept related to purposes, interactions and user behaviors.
Slow matching
Web 3 will not be implemented overnight. Some Internet users were familiar with it a decade before Web 1 became widespread. Web 2 became available by providing smart technology and social networks, but at the same time many users were struggling with chat rooms and how email works.
Many companies need a lot of time to transition from a centralized network to the Web 3 chain. Many devices will become obsolete, but their users cannot immediately shrink to Web 3. As a result, Web 2 and Web3 will coexist for a while.
Final Word
Human beings are on the verge of an internet revolution. There are many challenges upon the implementation of Web 3, but the developments in this technology can be quite dramatic. Of course, there is a need for more practical examples for Web 3 and an understanding of the positive changes it will bring us.
Just as Web 2 was able to defeat Web 1 through a series of innovations, Web3 will rule the realm of the Internet during a gradual process. No exact date has yet been set for web 3 release. The transition to Web 3 has already begun with the advent of Bitcoin and blockchain technology, P2P networks, decentralized applications, artificial intelligence technology and related technologies. Web 3 is evolving.
