What was Web1? (1990-2004)

The inception of the digital era began with Web 1.0 in the 1990s, marking the first significant strides in the web’s evolution. This stage of the web, often dubbed the “Read-Only” era, presented the internet as a space where information could be consumed, but the interaction was limited.

Web1 was defined by static, read-only pages where users had little to no opportunity to influence or interact with the content they were viewing. The information that had once been bound to newspapers and library shelves was now becoming accessible online. These static web pages served as digital libraries where users could glean information from a wider array of sources than ever before. However, the functionality was limited despite the vast amounts of data available.

The primary mode of communication during the Web1 era was through emails, a groundbreaking feature at the time. This presented a whole new level of connectivity, but the ability for users to generate their own content was virtually non-existent. Websites were primarily text-based, limited in multimedia content, and user participation was largely confined to reading information rather than creating or influencing it.

Despite these limitations, Web1 set the stage for future advancements. It marked the beginning of the digital age, converting physical information into digital format and making it globally accessible. While it might seem primitive by today’s standards, it was a crucial first step in the journey that has led us from the static, one-sided internet of Web1 to the dynamic, interactive Web2, and now towards the decentralized promise of Web3.

What is Web2? Read-Write (2004-now)

Emerging around 2004/2005, Web 2.0, also known as the “social web,” marked a significant evolution in the internet’s journey. For the first time, users could consume content and generate it, fostering a lively, interactive digital landscape. This interaction was made possible by technological advancements like JavaScript, HTML5, and CSS 3, which allowed websites to evolve from static pages to dynamic, interactive platforms.

Web 2.0 turned the internet into a “Read/Write” space, granting every user the power of content creation and interaction. Users could express their interests, share opinions, interact with others’ content, and even influence the type of content produced by news agencies, media outlets, and creators.

However, the democratization of content creation under Web 2.0 came with a price: the centralization of power. As tech companies like Facebook grew, the balance of power shifted from individual users to these corporate giants. Under the pretence of enhancing user experience, these companies began collecting vast amounts of personal data, often only to sell it to advertisers. In effect, users became the product, their data a commodity for companies to profit from.

Instances of seeing an ad for a coffee place on your Facebook newsfeed after a chat about the best coffee spots are all too common. These occurrences illustrate how our activities are constantly monitored and our data utilized. Privacy on the web became increasingly elusive, even when using features like Incognito mode.

However, these tech giants’ control is not limited to data collection. They can control user access, banning or limiting accounts if they deem users to be violating their terms of use. They can also curate what content users see, shaping the digital landscape according to their perspectives and interests.

While Web 2.0 propelled the development of the web to new heights, it also led to an unprecedented consolidation of control. This centralization has left a handful of entities with the power to make far-reaching decisions on behalf of the users, raising questions about privacy, data security, and freedom on the internet.

Web3, also known as Web 3.0, represents the next generation of the internet. This concept integrates the principles of decentralization, blockchain technology, and token-based economics into the World Wide Web.

In contrast to Web 2.0, where data and content are mostly centralized in a handful of large technology companies (also known as “Big Tech”), Web3 aims to distribute control across the network. The term “Web3” was initially coined by Ethereum co-founder Gavin Wood and has gained significant attention from cryptocurrency enthusiasts, technology companies, and venture capital firms since 2021.

Web3 envisions an internet where users have a financial stake and more control over their web communities. It includes applications in cryptocurrencies, non-fungible tokens (NFTs), decentralized autonomous organizations (DAOs), and decentralized finance (DeFi).

However, it is important to note that while Web3 offers potential solutions to privacy, centralization, and financial exclusion concerns, it also presents new challenges and risks. These include questions about data security, scalability, the potential for fraud, and the environmental impact of blockchain technologies. Critics also debate its potential to influence the power dynamics of the internet, both positively and negatively.

Overall, Web3 is anticipated to transform the online experience as dramatically as personal computers and smartphones did, marking a significant shift in how we interact with digital platforms.

Web3 Features

Web3 elevates the user experience to unprecedented levels of control and ownership. It marks an evolution towards a more democratic digital space where users consume and contributes content and exercises absolute ownership over their online assets and data.

So, let’s delve deeper into the intricate workings of Web 3.0 and explore its groundbreaking features and unique capabilities. We aim to provide you with an understanding of how Web 3.0 is redefining the Internet’s landscape and carving a path for a more egalitarian, user-centric digital future.

Users Become Decision Makers

Web3 empowers you to become more than a consumer or contributor; it allows you to be a decision-maker, controlling how you interact with the web. Instead of corporations dictating the use of your data, you decide its fate. If you opt to have your data sold to advertisers, fair compensation will be your right, not a courtesy. You can also choose to experience an ad-free web, keeping your data exclusive to you.

An existing example is the Brave Browser, which rewards users with its native crypto token BAT for opting to view ads.

Unleashing the Power of Permissionless

Web3 eliminates gatekeeping, embodying a permissionless environment. This means you can access any decentralized application on the internet using just your wallet, which requires nothing more than a functional email address to set up.

Decentralizing Authority

Web3 promotes a web ecosystem where no central authority can unjustly revoke your access. Furthermore, it empowers you to take part in the governance of your platforms. Community members can contribute to decision-making processes by utilizing decentralized autonomous organizations (DAOs) and protocol-specific governance tokens, creating a democratic environment where decisions are made collectively.

Leveraging Web3 Tools

In the Web 3.0 era, tools like NFTs, blockchains, and cryptocurrencies have become instrumental in restoring control of your web experience by eliminating middlemen. For instance, NFTs allow you to retain greater control of your digital assets, such as artwork, music, and tickets.

Eliminating a Central Point of Failure

Another distinctive feature of Web3 is its robustness, achieved by eradicating a central point of failure. In contrast to Web2 systems, where a single server’s failure can disable an entire platform, Web 3s decentralized architecture ensures continued operation even if a node goes down. Your data is distributed across multiple nodes, protecting the system against network outages and security breaches.

Whenever you go on YouTube to watch a video, you send a data request to a central server on YouTube, which stores all videos. Once the central server receives your request, it will find that video from its storage and play it for you on its website. If this central server goes down, you will not be able to access YouTube, and if it gets hacked, all the data stored on the server will get into malicious hands. 

This happened in October 2021 when Facebook’s central server went down and was unavailable for 6 hours, and the world came to a standstill. With a central source, there is a greater chance of network outage or failure.

With decentralization in Web3, data is distributed across several servers (or nodes), and there is no single point of failure. If one node is hacked or goes down, the system keeps functioning. 

Embracing Continuous Improvement

Web3 thrives on evolution and improvement. The code underpinning applications is open-source, allowing anyone to view it. Developers and tech enthusiasts can take this code, tweak it, and build improved versions, fostering a dynamic environment of continuous enhancement.


Interoperability is another key feature to consider. This refers to the ability of different systems and applications to work together, exchanging and using information. Web 3.0 promotes seamless interaction between different platforms and applications, creating a more connected and efficient Internet ecosystem.

Privacy and Security

Lastly, Web 3.0 places a heightened emphasis on privacy and security. Using cryptographic techniques and decentralized storage, Web 3.0 gives users enhanced control over their personal data and protects against unauthorized access and data breaches.

Examples of Web3

Web3 is currently a work in progress, but its main principle is to establish a decentralized internet experience not dominated by corporations or governments. This evolution seeks to give users more control over their online experience and data, with a backbone largely powered by blockchain technology.
