What is Web3? The ongoing revolution of the decentralized Internet

Web3 represents the new generation of the Internet—a network built on blockchain technology where data control is returned to users instead of being under the control of tech giants. Unlike the current Internet (Web 2.0), Web3 offers a decentralized, transparent, and more secure system for people to access online services.

From Web 1.0 to Web3: The Evolution of the Internet

To understand what Web3 is, we need to look back at the development journey of the Internet through three main phases.

Web 1.0 (1989-2004) was the era of one-way information, where users could only view and read static web pages. Businesses uploaded information, but there was no real interaction between users and platforms.

Web 2.0 began in 2004 with the rise of social media. This phase allowed users not only to read but also to write, share, and interact with each other. However, this convenience came at a cost—personal data was collected and controlled by large companies like Facebook, Instagram, and Twitter. These giants monetize user data through targeted advertising.

Web3, proposed by Dr. Gavin Wood (co-founder of Ethereum and founder of Polkadot) in 2014, aims for a “read-write-own” phase. In Web3, users not only create content but also own it through tokens and digital assets.

Blockchain Technology as the Foundation of Modern Web3

Blockchain—an encrypted, decentralized ledger—is the backbone of Web3. On this platform, decentralized applications (dApps) are developed and operated without any intermediaries.

Web3-supporting dApps are built on public blockchain networks like Ethereum, enabling millions of people to interact without trusting any company or organization. Smart contracts—self-executing programs on the blockchain—ensure all transactions are transparent and immutable.

Key Advantages of Web3 Compared to Web2

Decentralization and Data Control: In Web3, user data is not stored on a single company’s server but distributed across the network. Users retain full control over their personal information.

Permissionless Access: Unlike Web2, where companies decide who can access, Web3 allows anyone to use services without permission from any authority. Anyone can create or use dApps.

Trustless Operation: Web3 protocols are designed to operate in a “trustless” manner—users do not need to trust any company but rely on code and mathematics. Smart contracts automatically execute without intermediaries.

Cryptocurrency Payments: Web3 uses cryptocurrencies as a medium of exchange, enabling fast, low-cost transactions without traditional banking. This opens financial services to billions of unbanked people.

Enhanced Security: Thanks to blockchain encryption and the immutability of records, Web3 offers higher security. Every transaction is verified cryptographically.

Scalability and Interoperability: Web3 is designed to work seamlessly with different systems and technologies, making applications easier to scale.

The Diverse and Growing Web3 Ecosystem

Web3 is not just a concept; it has become a reality through numerous practical applications.

Decentralized Finance (DeFi) is considered the most significant Web3 application. Protocols like Uniswap (a decentralized exchange) and Aave (a lending platform) allow users to trade, lend, and borrow cryptocurrencies without traditional banks. DeFi has improved access to financial services for millions.

Non-Fungible Tokens (NFTs) have created a new way to own and trade digital assets or represent ownership of real-world assets. NFTs enable content creators to directly own and profit from their work.

GameFi combines blockchain gaming with economic incentives. Games like Axie Infinity and STEPN allow players to earn real cryptocurrency by playing. This Play-to-Earn model has attracted millions of new users to Web3.

Metaverse—virtual worlds built on blockchain—allow people to interact, shop, and host events in fully digital environments. Projects like The Sandbox and Decentraland are reshaping how we live online.

Decentralized Social Media platforms like Mastodon, Audius, and Steem offer alternatives to Facebook and Twitter, where users have full control over their content and data without being tracked or exploited for advertising.

Decentralized Storage uses networks like IPFS, supported by projects such as Filecoin and Storj, enabling secure, affordable data storage without control by a single company.

Decentralized Identity through Web3 wallets like MetaMask or Halo Wallet allows users to have a single identity usable across hundreds of Web3 applications, reducing the need to create separate accounts for each service.

What Opportunities Does Web3 Offer to Investors?

For cryptocurrency investors, Web3 is not just a technological trend but an opportunity to participate in a new digital economy.

Tokens are used to incentivize economic activity within the Web3 ecosystem, encouraging optimal actions from all participants. Token holders can earn rewards or have voting rights in decentralized autonomous organizations (DAOs).

In a DAO, token holders influence how a dApp operates and develops. This is a stark contrast to Web2, where decision-making is centralized among company leaders. This decentralized governance makes decision-making more democratic and transparent.

Cryptocurrencies also enable decentralized ownership. Instead of Web3 protocols being owned by a single company, they are owned by their users. By buying and holding tokens, investors become part-owners of the network.

Is Web3 Truly the Future?

Although Web3 is still in development, signs indicate it has the potential to become the future of the Internet.

Every day, users are losing trust in Web2. They no longer want large corporations to control their data and privacy. Web3 offers an alternative—where users regain control.

However, Web3 still faces challenges such as scalability, security, and public adoption. Emerging technologies like artificial intelligence, machine learning, and natural language processing will be integrated into Web3, making it more intuitive and user-friendly.

Conclusion

Web3 signifies a fundamental shift in how we use the Internet. Moving from a centralized network controlled by a few companies, it aims toward a decentralized system where users, creators, and communities hold real power.

Web3 offers undeniable benefits: greater privacy, enhanced security, expanded earning opportunities, and democratic governance. Although still in its early stages, Web3 has proven that it is not just a trial but the beginning of a true Internet revolution.

The question is not whether Web3 will become the future, but how we will participate in this revolution.
