Web3 refers to the third generation of the World Wide Web, emphasizing decentralization, blockchain technology, and user empowerment. Web3 represents a paradigm shift in how we interact with the internet, moving from centralized platforms to decentralized networks. This transition is driven by blockchain technology, which enables peer-to-peer (P2P) interactions without intermediaries. Web3 enables internet users with more control over their data and digital identities. 

‍

In this blog, we will explore various aspects of Web3, including its definition, its relationship with cryptocurrency, wallets, practical applications, and learning opportunities. But to understand Web3 fully, it is essential to explore its predecessors.

What Was Available Before Web3?

Web1 (The Static Web): The first version of the internet emerged in the early 1990s and was characterized by static web pages that provided information but lacked interactivity. Users could read content but had limited ability to contribute or engage with it. Websites were primarily informational and did not allow for user-generated content.

‍

Web2 (The Social Web): Emerging in the early 2000s, Web2 introduced interactivity and user-generated content. Platforms like Facebook, Twitter, and YouTube enabled users to create profiles, share content, and engage with one another. However, this era also saw the rise of centralized platforms that controlled user data and monetized it through advertising models. While users enjoyed enhanced connectivity and collaboration, they often relinquished control over their personal information to these platforms.

What Is Web3 All About?

‍

Web3 is often described as the “decentralized web.” It aims to create a more user-centric internet where individuals have control over their own data and digital identities. Unlike its predecessors, Web3 leverages blockchain technology to decentralize data storage and management. This means that users can interact directly with one another through smart contracts, self-executing contracts, with the terms of the agreement directly written into code, without needing a central authority. In simple terms, Web3 is all about making the internet transparent, open and giving power back to the user rather than to intermediaries or central authorities.

Ownership: One of the primary goals of Web3 is to return control to users. Through decentralized applications and platforms, individuals can own their data and have more agency over their online experiences without being subjected to corporate policies or advertising algorithms. This means users have full control over their digital assets and personal information. 

Smart Contracts: Smart contracts are self-executing contracts executing automatically according to the terms directly written into code. They automate processes and transactions, eliminating the need for intermediaries and reducing costs.

Interoperability: Web3 promotes interoperability among different platforms and services through open standards and protocols. This means users can move their assets seamlessly across various applications without being locked into a single ecosystem. Web3 encourages different applications to work together seamlessly due to standardized protocols.

‍

Trustlessness: Transactions can occur without needing to trust a third party.  Instead, trust is established through cryptographic verification and consensus algorithms.
