Internet, the network of networks connecting computers worldwide, emerged in 1969 and has since undergone numerous technological and infrastructural modifications to reach what it is today. The initial purpose of the internet as a means of sharing information has extended way beyond that over the years, and has become an essential part of our lives. The introduction of the World Wide Web by Tim Berners-Lee has played a major role in transforming our lives in novel ways.
The web, elaborated as the World Wide Web, is a collection of websites built on top of the internet. These websites contain information in the form of text pages, digital images, videos, audio etc., which users can fetch from anywhere in the world. Invented in 1989, the WWW has evolved gradually from its initial static page state to the more interactive version we witness today.
Now, as the internet is advancing towards its third iteration and many technological changes and heated discussions are going around it, many are confused about the difference between Web3 and Web 3.0. Although most discussions revolving around the third generation of the web imply that Web3 and Web 3.0 are the same, both are fundamentally different. While Web3 is a decentralized, blockchain-based version of the web, Web 3.0 highlights Tim Berners-Lee’s concept of a linked or semantic web.
What is Web3?
Web3 is a decentralized and open web based on blockchain technology. Coined by the Ethereum co-founder Gavin Wood in 2014, the fundamental idea behind Web3 is to create a decentralized version of the internet by removing the dominance of the centralized power of Web 2.0 giants like Amazon and Facebook and giving the control back to users. Web3 hopes to reclaim data ownership from Web2 giants and return it to users using blockchain technology, decentralized storage, and self-sovereign identity in a community-driven environment.
Users will have the final say regarding who can access what data. This has been made possible by cryptocurrency wallets like MetaMask, Venly, or TrustWallet, where users store keys to all of their data and identities. They may engage with other blockchain apps in this way and control who has access to their data. Using a crypto wallet to log in to other apps is similar to using a Facebook account, except that all your data is yours to keep and manage.
What is Web 3.0?
Comprehended as the next generation of the web, Web 3.0 is the executable web or read-write-execute version of the web. It is also known as semantic web and is an extension of the World Wide Web that uses standards set by the World Wide Web Consortium (W3C). It aims to make the Internet smarter by handling information with human-like intelligence using artificial intelligence systems.
Tim Berners-Lee coined the term Semantic Web, which refers to a version of the web that can connect everything at the data level. He stated that with the emergence of the semantic web, “the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The “intelligent agents” people have touted for ages will finally materialize.”
In the present-day internet, there are information silos. For instance, the information you upload on LinkedIn will not be automatically updated on Facebook or Twitter because they are not linked. Berners-Lee aimed to connect all the information by linking web pages and making them interoperable so that no one ever needed to upload their information separately on different online platforms.
Difference between Web3 and Web 3.0
The semantic web, known as Web 3.0, focuses on efficiency and intelligence by reusing and linking data across websites. The decentralized web or Web3, however, puts a strong emphasis on security and empowerment by returning control of data and identity to users. Semantic web uses a central place called the solid pod to store all user data, enabling users to handle third-party access to their data.
Solid pods also issue a unique WebID for users that act as an identity within the ecosystem. In the blockchain-based Web3, users can store their data in a cryptocurrency wallet, which they can access using their private keys. Additionally, they both use different technologies to implement their purpose of data security. Web3 uses blockchain technology, while in Web 3.0, certain data interchange technologies like RDF, SPARQL, OWL, and SKOS are used.
Data in Web3 is difficult to modify or delete since it is scattered across multiple nodes; however, data in Web3.0 can be changed effortlessly. Furthermore, the data stored in the solid pod is centralized, while the keys stored in crypto wallets provide access to the data of assets that reside on a blockchain.
Similarities between Web3 and Web 3.0
Although both Web3 and Web 3.0 are similar in names, there is a huge difference in their concepts and approach. However, they both have a common purpose. Both Web3 and Web 3.0 aim to create a better version of the internet by maintaining users’ control over their data. The core difference lies in the approach taken to reach this purpose. While data is stored in a solid pod in the semantic web, Web3 uses decentralized technologies for the same.
Endnote
Many people across the globe consider Web3 the same as Web 3.0. They believe that the future of the web will be an integration of vital Web 3.0 elements like machine-readability, and Web3 aspects like blockchain or the metaverse. However, even though the semantic web concept seems logical, it never attained mainstream popularity.
Web3, on the other hand, is currently in the spotlight owing to the benefits offered by decentralization, digital assets, smart contracts, open-source platforms, etc. With growing use cases and real-life applications, Web3 seems to be the need of the hour, possessing the potential to revamp every aspect of our lives.
