What Is Web3: Why Do We Need the Third Generation of the Internet

What Is Web3

Web3 (or Web 3.0) refers to the concept of a decentralized internet. To understand how this new paradigm differs from the World Wide Web as we know it, it's essential to revisit the history of this technology and its early versions.

The evolution of the internet is divided into three distinct generations, each introducing major innovations. Web3 represents the latest stage in this progression, aiming to solve the problems inherent in earlier versions while unlocking new opportunities for users and developers.

General History of the Internet

The modern internet descends from ARPANET, a network created in 1969 at the request of the Advanced Research Projects Agency of the US Department of Defense. Building on that foundation, the US National Science Foundation developed the open NSFNET network fifteen years later. This project enabled data transmission between universities and data centers. By 1992, approximately 7,500 networks were connected to NSFNET.

Simultaneously, scientists developed email transmission technology. This method gave rise to Usenet in 1980, the first mass network for data exchange. Efforts to build data exchange networks also took place in other countries, including Chile and the United Kingdom. Together, these global developments laid the groundwork for the first iteration of the World Wide Web.

The term "internet" emerged in 1983 during ARPANET's transition to the TCP/IP protocol, a network model for data transmission. The World Wide Web project, introduced in 1989 by Tim Berners-Lee, marked a pivotal moment in the history of digital communication.

The timeline continued: in 1990, the first browser was created, with public access following in 1991. By 1995, responsibility for internet development shifted to the private sector, a move that fueled World Wide Web audience growth and paved the way for widespread commercialization.

Web1: The First Generation Internet

The first generation of the internet was extremely limited in functionality. Web1 was primarily used for one-way distribution of text data. This era, often called the "static web," spanned roughly from 1991 to 2004.

First-generation internet consisted mainly of static pages hosted on web servers operated by access providers. Web1 users had very limited capabilities. For example, the initial version of the internet didn't allow for interactive content editing. Updating websites was also very difficult, requiring advanced technical expertise in HTML and server management.

Websites from this period resembled digital brochures more than interactive platforms. Users were passive consumers of information with no real way to contribute or interact with content. This limitation set the stage for a shift toward a more interactive internet.

Web2: The Second Generation Internet

The second generation of the internet emerged during the so-called "dot-com bubble" between 1995 and 2001. This period became known for the rapid rise in internet company stock prices. Many startups—whose shares soared amid excitement over new technology—fell short of expectations, leading to a major market crash.

Web2 features more sophisticated website design and expanded functionality. Internet platforms that survived the dot-com crash, such as Amazon, allowed users to leave reviews and comments. Online encyclopedias like Wikipedia appeared, enabling users to collaboratively edit entries.

Developers began launching platforms that made remote communication easier. Notable examples include Facebook, Twitter, YouTube, and other social networks that transformed how we share information and interact online. This era marked a shift from a static web to a dynamic, participatory one.

However, the rise of Web2 also brought about censorship. Platform owners started banning users whose opinions they or the community found objectionable. This centralization of moderation power raised significant issues around freedom of expression and control of information.

Centralization is another major drawback of Web2. The servers that run internet platforms are vulnerable, and outages can prevent users from accessing important sites. Tech giants also collect massive amounts of personal data, fueling growing concerns about privacy and security.

Web2 is more technically advanced than Web1, but it comes with major disadvantages. The answer to these issues may lie in Web3, which promises to return control to users while preserving the benefits of interactivity.

Web3: The Third Generation Internet

The term Web3 was first coined by Gavin Wood, co-founder of Ethereum, in 2014. According to Wood, the third-generation internet will be a decentralized evolution of Web2. This new network, he argues, will be more resilient, secure, and transparent than its predecessor.

In Web3, users will be able to interact with the metaverse and non-fungible tokens (NFTs), which developers use to enrich digital worlds. This immersive, ownership-driven dimension marks a fundamental shift in how we perceive digital property and online identity.

The foundation of Web3 is likely to be decentralized applications (dApps). Blockchain will serve as the common thread connecting all third-generation internet components. This technology enables distributed data storage, protecting platforms from going offline due to server failures or other technical problems by creating multiple copies of information across users' computers.

Blockchain ensures data protection and authenticity. Its design makes it impossible for anyone to delete or falsify any part of the information recorded and verified by network participants. This immutability is one of blockchain technology’s most revolutionary features.

System automation will be provided by smart contracts. This approach reduces users' reliance on intermediaries, making transactions faster, cheaper, and more transparent. Smart contracts automatically execute pre-programmed agreements when specific conditions are met.

Financial relationships in Web3 will be managed through decentralized finance (DeFi). This concept abandons centralized credit institutions in favor of a distributed system of digital assets. Users can lend, borrow, trade, and invest without traditional banks.

Web3-compatible applications are already available, including crypto wallets, decentralized exchanges, and digital identity management apps. However, large-scale integration of Web3 is still premature, as significant technical and regulatory challenges remain.

Why Is Web3 Better Than Previous Versions of the Internet?

The core advantage of Web3 is its emphasis on decentralization. This approach ensures network stability and protects user data. Blockchain-based internet also enables parties to eliminate intermediaries, increasing transaction speed and cutting unnecessary costs.

Decentralization shields users from censorship and empowers the internet community to break free from the influence of large corporations. In Web3, no single entity can arbitrarily control or censor content. This resistance to censorship is especially critical in regions where freedom of expression is limited.

Web3 gives users control of their personal data. Unlike Web2, where tech giants collect and monetize user information, Web3 allows individuals to own and govern their data. Users can choose what to share and with whom, and may even be compensated for this use.

Transparency is another major benefit of Web3. All transactions and interactions recorded on the blockchain are verifiable and traceable, greatly reducing fraud and manipulation risk. This transparency extends to platform governance, where decisions can be made democratically by the community rather than a central authority.

Web3 lowers barriers to entry and encourages innovation. Developers can build applications without needing approval from a central gatekeeper or paying high fees. This openness fosters creativity and enables disruptive business models.

Organizations that benefit from Web2 are likely to resist Web3 adoption, as it threatens their business models based on collecting and monetizing user data. Nevertheless, the trend toward greater decentralization, transparency, and user control seems inevitable as technology matures and public awareness grows.

Web3 also enables greater interoperability between platforms and services. Users will be able to move their data and digital assets between platforms without restrictions, creating a truly open and interconnected ecosystem. This portability is a fundamental shift from the "walled gardens" of Web2.

Finally, Web3 introduces new economic models based on tokens and cryptocurrencies, allowing for a fairer distribution of value created on platforms. Contributors—whether content creators, developers, or active users—can be directly rewarded for their participation, creating stronger incentives and more engaged communities.
