What is Web3 and How Does it Work?
Web3 is the next generation of the internet, built on decentralization and the elimination of intermediaries. Unlike Web2, where platforms like Facebook and Google control user data and interactions, Web3 empowers users by utilizing technologies like blockchain and smart contracts. In this model, information is not stored on Centralised servers but on a network of computers that no single entity can control or censor.
In simple terms, to answer the question “What is Web3?”, it can be described as a transformation that gives control of data, digital assets, and even online identity back to users instead of corporations.
How Does Web3 Work?
Here’s how Web3 operates:
- Blockchain: The backbone of Web3, blockchain creates a distributed, immutable ledger that allows for data storage and transfer without intermediaries. For example, financial transactions in Web3 are carried out through Decentralised networks like Ethereum, rather than banks.
- Non-Fungible Tokens (NFTs): NFTs prove digital ownership of unique assets (such as artwork or in-game items) in Web3. NFTs are recorded on the blockchain, making them nearly impossible to counterfeit or duplicate.
- Decentralised Autonomous Organizations (DAOs): In Web3, organizations are run as DAOs, where members participate directly in decision-making using governance tokens. This model replaces the hierarchical structure of traditional companies.
If you’re still wondering “What is Web3 and how does it relate to cryptocurrency?”, the answer lies in how Decentralised networks are valued. Many Web3 protocols have their own native tokens (like Ethereum or Filecoin), which serve both as network fuel and governance tools.

The Evolution of the Internet from Web 1.0 to Web 3.0
Since its inception in the late 20th century, the internet has undergone remarkable transformations. The question “What is Web 3?” leads us to explore the evolution of the internet from Web 1.0 to Web 3.0. This journey reflects big changes in how users interact with the digital world.
| Era | Timeframe | Interaction | Example |
| Web 1.0 | 1990–2004 | Read-Only (Static) | Yahoo Directory, Personal HTML pages |
| Web 2.0 | 2004–Present | Read-Write (Interactive) | Facebook, YouTube, Twitter |
| Web 3.0 | 2014–Future | Read-Write-Own (Decentralised) | Ethereum, Uniswap, Brave |
Web 1.0: The Era of Static Information (1990-2004)
The first generation of the internet, Web 1.0, was defined by simple HTML pages and one-way communication. During this period, users were primarily content consumers, with no ability to interact or generate content. Websites like Yahoo or early directories were prime examples of this era. The key feature of Web 1.0 was its focus on delivering information without user participation. The internet, at the time, functioned more like a “digital book.”
Web 2.0: The Revolution of Interaction and Participation (2004-present)
With the emergence of Web 2.0 in the early 2000s, the internet became an interactive, user-centered space. Known as the “read-write web,” this period saw the rise of social networks like Facebook and YouTube. Technologies such as JavaScript, AJAX, and HTML5 enabled the creation of dynamic, interactive content. Users became not only consumers but also producers of content. However, Web 2.0 remained under the control of large corporations, which collected and managed user data.
Web 3.0: The Birth of the Decentralised Internet (2014-present)
Introduced in 2014 by Gavin Wood, Web 3.0 is the vision for a Decentralised internet. Using blockchain technology, Web 3.0 gives control of data back to the users, eliminating intermediaries. Decentralised applications (dApps) and smart contracts strengthen this ecosystem, offering a transparent and secure experience. Web 3.0 is redefining the internet as a space where users are at the center.
Why Was This Transformation Necessary?
While Web 2.0 brought many benefits, it also introduced problems such as data misuse, censorship, and economic monopolies. Web 3.0 addresses these challenges by returning control to the users. Today, projects like Ethereum and IPFS are laying the technical foundations of Web 3.0, demonstrating how the future internet can be freer and fairer.
The Difference Between Web 3 and Web 2
To understand what Web3 is, it is essential to compare it with Web2. Web2 and Web3 differ significantly in terms of data management, digital ownership, and privacy, which dramatically change our internet experience.
In Web2, large companies like Google and Facebook collect and control user data. When you use platforms like Instagram or YouTube, your information is stored on their servers, often used for advertising purposes. This means you have little control over your data, and your privacy may be compromised. For instance, incidents like data breaches have shown how vulnerable Web2 can be.
On the other hand, Web3 tells a different story. Using blockchain technology, Web3 stores data on a Decentralised network. This means you own your data and digital assets. For example, with digital wallets or NFTs, you can choose with whom to share your information.
Furthermore, Web3 provides enhanced security. Since data is encrypted and not stored on Centralised servers, it is much harder to hack. Web3 also increases transparency, as all transactions are traceable and immutable. These differences make Web3 an attractive option for the future of the internet.
Here’s a summary table to help understand the differences better:
| Feature | Web 2 | Web 3 |
| Data Control | Controlled by large companies (Centralised) | Controlled by users (Decentralised) |
| Digital Ownership | Limited. Data belongs to companies | Full ownership. Users own their data |
| Privacy | Vulnerable. Risk of data breaches | Safer. Encrypted data |
| Transparency | Low. Dependent on companies | High. Transactions are traceable and immutable |
