What is Web3 and Why Should You Care? 

You may have heard the term “web3” being thrown around lately, especially in the context of cryptocurrencies, NFTs, DAOs, and other blockchain-related buzzwords. But what exactly is web3 and how does it differ from the web we know today?

Web1, Web2, and Web3: A Brief History

• To understand web3, we need to go back to the origins of the World Wide Web. The web was invented by Tim Berners-Lee in 1989 as a way to share information across networks of computers. The first version of the web, known as web1, was mostly static and read-only. Users could access websites and documents, but they had little interaction or control over them. Web1 lasted from 1989 to around 2004.

• The second version of the web, known as web2, emerged around 2004 and introduced the concept of “the web as platform”. Web2 enabled users to create and share content on platforms like social media, blogs, wikis, and online forums. Web2 also enabled new business models based on advertising, data collection, and cloud computing. Web2 is still the dominant paradigm of the web today. 

• The third version of the web, known as web3, is an idea for a new iteration of the web that incorporates concepts such as decentralization, blockchain technologies, and token-based economics. Web3 aims to give users more control over their own identity and data, as well as enable new forms of collaboration and innovation. Web3 is still in its early stages of development and adoption.

What are the Key Features of Web3?

Web3 is not a single technology or platform, but rather a collection of technologies and trends that are expected to shape the future of the web. Some of the key features of web3 are:

Decentralization: Web3 relies on distributed networks of computers (called nodes) instead of centralized servers or intermediaries. This means that users can interact directly with each other without relying on third parties that may be vulnerable to censorship, corruption, or hacking. Decentralization also enables more resilience, security, and transparency in the web.

Blockchain: Blockchain is a type of distributed ledger that records transactions or events in a secure and verifiable way. Blockchain enables trustless and peer- to-peer exchange of value or information without intermediaries. Blockchain also enables smart contracts, which are self-executing agreements that run on the blockchain according to predefined rules.

Cryptocurrencies: Cryptocurrencies are digital currencies that are powered by blockchain technology. Cryptocurrencies enable users to transact online without intermediaries or central authorities. Cryptocurrencies also enable users to ownand control their own money, as well as participate in new forms of economic activity.

Non-fungible tokens (NFTs): NFTs are unique digital assets that represent ownership of something online. NFTs can be anything from art, music, games, collectibles, to real-world assets. NFTs enable users to create and trade digital scarcity and value online.

Decentralized autonomous organizations (DAOs): DAOs are organizations that run on the blockchain according to encoded rules and without human intervention. DAOs enable users to collaborate and coordinate on common goals or projects without hierarchy or bureaucracy.

Decentralized finance (DeFi): DeFi is a term for financial services that run on the blockchain without intermediaries or central authorities. DeFi enables users to access services such as lending, borrowing, trading, investing, saving, and more in a decentralized and open way.

Why Should You Care About Web3?

Web3 is not just a technological innovation, but also a social and cultural movement.

Web3 offers a vision for a more open, democratic, and participatory web that empowers users and creators over platforms and intermediaries. Web3 also offers new opportunities for innovation, collaboration, and value creation that were not possible before.

Web3 is still in its infancy and faces many challenges and uncertainties. However, it also represents a huge potential for transforming the way we interact with each other and with the world online.
