Web3 Revolution: From Concept to Practice, How Decentralized Internet Is Changing Things

Web3 is not the future, but the present

Web3, also known as Web 3.0, represents the third evolution of the internet. It is a decentralized network ecosystem built on blockchain technology, fundamentally different from today’s internet dominated by tech giants. In Web3, users no longer need to entrust their data to centralized institutions but have full control over their information and digital assets.

Compared to traditional centralized online services, Web3 is reclaiming power from large tech companies and returning it to ordinary users. Decentralized applications (dApps) built on public blockchains like Ethereum have already covered fields such as gaming, social media, and finance, and this ecosystem continues to expand rapidly.

Gävyn Wood first proposed the concept of Web3 in 2014. He is the co-founder of Ethereum and Polkadot. His vision is simple: to free the internet from reliance on a few private enterprises and create a more transparent, open, and secure network. Although Web3 is still in its early stages, its supporters firmly believe it will fundamentally change how we access and use online services.

From Web 1.0 to Web 2.0, and then to Web 3.0: The collision of three eras

To understand the revolutionary significance of Web3, we must review the evolution of the internet.

Web 1.0 (1989-2004): Read-only internet

The early internet was like a giant online encyclopedia. Companies and organizations published websites, and users passively read information. It was a unidirectional, static online space with no real user interaction.

Web 2.0 (2004-present): The rise of read-write era

After 2004, social media emerged. The internet suddenly became lively—users could not only read but also write, share, and interact. Platforms like Facebook, Instagram, and Twitter turned everyone into content creators. This seemed like a victory for democratization, but problems soon arose: these platforms control all user-generated data, used for targeted advertising and user tracking, creating new centers of power. Over time, concerns about data privacy increased.

Web 3.0 (2014-present): The “Read-Write-Own” era

Web3 introduces a third dimension—ownership. In this stage, users can read, create, and truly own their digital assets and data. Web3 is called the “Read-Write-Own” internet, leveraging blockchain, smart contracts, and crypto assets to build decentralized ecosystems. Power is no longer concentrated but distributed among all participants in the network.

How Web3 changes the game: Six core features

Web3’s disruptive nature stems from its unique technological features.

Decentralization

Web3 applications run on public blockchains, no longer relying on a single centralized authority. Users have complete control over their data, and no one can arbitrarily track or misuse this information.

Permissionless access

Unlike Web2’s walled garden model, Web3 platforms are open to everyone. Users, developers, and organizations participate on equal footing, with equal rights to create, use, and monetize services.

Trustless mechanisms

Web2 requires users to trust platform operators. Web3 differs—through smart contracts and transparent code mechanisms, trust is embedded into the system design. Token incentives ensure all participants act according to rules, eliminating the need for third-party trust.

Cryptocurrency payments

Web3 uses cryptocurrencies as the economic infrastructure. This means faster payments, lower costs, and direct transfers between users. For the global population without bank accounts, this opens the door to participation in the digital economy.

Security and privacy

Blockchain’s cryptographic features provide inherent security for dApps. Smart contract code is transparent and verifiable. Compared to Web2 applications’ black-box operation mode, this offers unprecedented auditability and trustworthiness.

Scalability

Web3 is designed as an architecture that can seamlessly integrate with various systems. This flexibility allows different applications and platforms to collaborate easily, breaking down barriers between Web2 applications.

Integration with AI, ML, and natural language processing

Web3 is evolving alongside cutting-edge technologies like artificial intelligence, machine learning, and natural language processing, enabling dApps to offer highly intuitive user experiences from the start. Upgrading Web2 applications to incorporate these technologies is much more difficult.

Web3’s seven application domains: Reshaping industries

Web3 is not just a theoretical concept—it has already made tangible impacts across multiple fields.

Decentralized Finance (DeFi) democratization

DeFi is the most mature Web3 application. Protocols like Uniswap and Aave enable peer-to-peer trading, lending, and yield farming, bypassing traditional intermediaries like banks and exchanges. DeFi opens financial services to billions without bank accounts, providing access to loans, investments, and wealth growth opportunities.

NFTs empowering creativity

Although the NFT boom of 2021 has cooled, the market’s true potential is just emerging. NFTs can represent ownership of digital art and real-world assets. For content creators, NFTs offer unprecedented control, transparency, and reward mechanisms. As technology matures, NFTs could become a key driver for large-scale Web3 adoption.

GameFi: A new paradigm of earning through gaming

“Play-to-Earn” (P2E) surged in 2021, attracting many new users to crypto. Games like Axie Infinity and STEPN prove that gaming is not just entertainment but can be a real income source. Blockchain games allow players to earn real rewards for their time and effort, creating new revenue models for developers.

Metaverse: The new frontier of virtual worlds

Compared to Web3, more people have heard of the metaverse. But did you know? Web3 is the true engine behind the metaverse. Blockchain-based metaverse projects like The Sandbox and Decentraland offer unprecedented virtual interaction modes. Coupled with augmented reality (AR) and virtual reality (VR), the metaverse has the potential to change how people live and work.

Decentralized social networks

Web2 social giants like Facebook, Instagram, and Twitter dominate, but they are also the main reasons users crave more privacy and control. Decentralized social networks (e.g., Mastodon, Audius, Steem) do not harvest user data for advertising but instead return power to users. This is true “social democratization.”

Distributed storage: Data’s private fortress

Cloud services like AWS saved many enterprises in Web2, but centralized storage carries risks and high costs. Web3 offers decentralized, persistent, encrypted cloud storage solutions that are cheaper and more scalable. IPFS-driven distributed networks like Filecoin and Storj enable secure data storage on the blockchain.

Decentralized Identity (DID): One wallet, countless applications

As Web3 adoption grows, decentralized identity may become the next explosive field. Unlike traditional centralized identity systems, Web3 wallets (e.g., MetaMask or Halo Wallet) allow users to access hundreds of dApps with a single account. Users gain more control over personal information and intellectual property, and accounts are less vulnerable to hacking or damage, eliminating the need to create new accounts for each service.

Why crypto investors must pay attention to Web3

Web3 runs on blockchain—this is the infrastructure underlying cryptocurrencies. Digital assets and crypto tokens play dual roles in the Web3 ecosystem.

First, they serve as economic incentives. Users earn tokens for generating content, which can be traded or used to purchase services.

Second, tokens enable decentralized governance. Token holders have voting rights in DAOs (Decentralized Autonomous Organizations), participating in decisions on how a dApp operates and develops. This distributed consensus process makes decision-making more transparent and democratic than centralized Web2 services.

Tokens also democratize management decisions. Unlike centralized organizations owned by corporations, decentralized protocols are owned by their users. Users establish this ownership by issuing and managing their own tokens.

Conclusion: Is Web3 really the future of the internet?

The next wave of the internet will revolve around content creation, consumption, and value discovery. Here, blockchain and crypto-based decentralized networks offer the most promising use cases—providing all stakeholders with participation, growth, and measurable value.

Web3 offers a more interactive mode of engagement, where enterprises and consumers are no longer passive but active participants, earning real rewards. Unlike Web1 and Web2, Web3, through monetary incentives, decentralized ownership, and governance, can make dApps more responsible, inclusive, and lay the foundation for long-term growth.

As each day passes, distrust and disappointment in the existing internet deepen. People no longer want to trust centralized intermediaries that might abuse their content and shared data. Web3 empowers consumers and creators—taking back control from centralized powers providing online services.

With semantic metadata technology, Web3 will undoubtedly become the future and direction of the internet. The question now is: Are you ready to join?
