What is Web3?

Definition and Basic Concept

Web3 represents the latest paradigm in the evolution of the internet. Where previous iterations of the web were centralized, Web3 introduces a decentralized model. At its core, it integrates the technologies and concepts central to cryptocurrency: decentralization, token-based economies, and blockchain. It’s often described as the “read/write/own” version of the internet, emphasizing the idea of ownership and control by its users.

Comparison with Web2.0: Centralized vs. Decentralized Internet

Web2.0 ushered in a new era of interactivity, characterized by user-generated content, social connectivity, and dynamic web applications. Companies like Apple, Amazon, Google, and Meta (formerly Facebook) rose to prominence, becoming global giants. While this era marked a significant advancement from the static pages of Web 1.0, it was inherently centralized, with a few dominant platforms controlling significant portions of the web. On the contrary, Web3 aims to decentralize the web, reducing the influence of these central entities.

Brief on the Evolution of the Internet: Web1.0 (Read), Web2.0 (Read/Write), and Web3.0 (Read/Write/Own)

Web 1.0: Pioneered by Berners-Lee in the early 1990s, this era was characterized by static webpages and limited interactivity. Most content was read-only, and users mainly enjoyed features like email and real-time news retrieval.

Web 2.0: The early 21st century saw a transformation in how the internet was used. Interactivity, social connectivity, and user-generated content became the norm. The rise of platforms like Facebook, Twitter, and YouTube enabled users not only to read but also to write or contribute to the internet.

Web 3.0: As the next phase in the internet’s evolution, Web3.0 emphasizes user ownership and decentralization. It champions the “read/write/own” philosophy, with blockchain technology facilitating a decentralized, transparent, and user-centric internet model.


The Features and Attributes of Web 3.0


At the heart of Web 3.0 lies decentralization. Unlike Web 2.0, where information retrieval is reliant on unique web addresses pointing to singular server locations, Web 3.0 enables data retrieval based on content, allowing for storage across various locations. This inherently decentralized structure promises to dismantle the massive databases that central entities like Google and Meta currently maintain. Furthermore, it paves the way for user-controlled data dissemination, as the data generated from diverse computing devices can be shared and sold on decentralized networks. In essence, users gain the upper hand, maintaining ownership and control over their data.

Trustless and Permissionless Systems

Driven by open-source foundations, Web 3.0 champions a trustless and permissionless environment. The “trustless” attribute ensures direct interactions between participants without the need for intermediaries. Simultaneously, being “permissionless” denotes an inclusive platform, allowing any individual to participate without seeking approvals or authorizations. These characteristics inevitably lead to the rise of decentralized applications, commonly termed as dApps, which operate either on blockchains, decentralized peer-to-peer networks, or a blend of both.

The Advent of AI and Machine Learning

Web 3.0 will usher in an era where machines can understand and process information in ways that mirror human comprehension. This is realized through the integration of Semantic Web methodologies and advanced natural language processing techniques. Additionally, machine learning, a subset of artificial intelligence (AI), will play a pivotal role. This technology enables systems to learn and refine their operations based on data, imitating human learning processes. Such advanced computational abilities are set to revolutionize sectors far beyond just targeted advertising. For instance, breakthroughs in drug research and material innovation could be on the horizon.

Connectivity and Ubiquity

Web 3.0 promises an interconnected and omnipresent digital ecosystem. Content and information will no longer be siloed, but instead, be accessible through a myriad of applications and devices. This surge in connectivity is epitomized by the Internet of Things (IoT), where everyday objects, from refrigerators to cars, are interlinked via the web. Such a seamless integration across platforms and devices signifies a shift towards a more unified and accessible digital realm.

Key Applications of Web 3.0

Epitomizing a futuristic model of governance, DAOs leverage the prowess of smart contracts to instantiate entities that are both self-regulating and unbounded by physical frontiers. They present a radical departure from traditional organizational hierarchies, suggesting a new era of collaboration and decision-making.

Decentralized Finance (DeFi)

Witnessing an unprecedented surge in 2020, decentralized finance (DeFi) platforms have empowered users with a suite of financial services, from trading and staking to borrowing and lending, all without centralized oversight. Despite grappling with security pitfalls, DeFi holds the promise to extend financial inclusion, reaching the vast populace underserved by conventional banking institutions.

Benefits of Web3

Privacy and User Sovereignty

One of the most touted advantages of Web 3.0 is the empowerment it provides to users concerning their digital identities. As opposed to the Web 2.0 paradigm where user data is often controlled by central platforms, Web 3.0 bestows individuals with unparalleled control over their personal information. This paves the way for enhanced privacy, reduced surveillance, and fewer instances of data misuse.

Democratization and Inclusivity

Web 3.0 envisions an online ecosystem where every participant, regardless of their background, has an equal stake.
