The newest version of the Web is known as Web3, or Web 3.0. Web 2.0 is the current version of the Internet, and social media platforms and centralization have taken over. The majority of people are often concentrated on regulated social media platforms. Most of their data is kept in cloud storage facilities and on centralised data servers. On centralised web servers and centralised cloud servers, the web applications are hosted. Let’s take a closer look at Web 3.0 in this essay and the key technologies that will shape it.
The Semantic Web is what Tim Barners-Lee named it. The phrase “Web3” was first used in 2014 by Ethereum co-founder Gavin Wood, who sees decentralised technologies as the Web’s future. Elon Musk recently questioned whether anyone had seen web3 on Twitter. It’s between a and z, Jack Dorsey, the creator of Twitter, retorted.
No matter what you call the next generation of the Web—Web3 or otherwise—almost it’s here. The purpose of this article is to explain Web3 and the technologies that make it up. However, before doing that, it is important to know what Web 1.0 and Web 2.0 are.
1989 – 2005
The World Wide Web (W3 or WWW), often known as the Web, is a network of interconnected computer systems that employs URLs (Uniform Resource Locators) to access and transfer digital content using Web browsers. The network is connected via the Hypertext Transfer Protocol (HTTP) protocol. Web applications, which are hosted and run on a Web Server, are used to host and manage the content (web pages, files, photos, videos, and other documents).
Tim Berners-Lee, an English scientist, and Robert Cailliau, a co-inventor, developed the World Wide Web in 1989. Tim created the first web browser in 1990 while working as a contractor at CERN near Geneva, Switzerland. It was made available to the public in 1991.
Web 1.0 was the first version of the Web, and it was mostly made up of static web pages that were linked to and contained HTML-based content. Users used the majority of the content that was written and published on the Web servers to publish and share information with others. The user interfaces were static and unresponsive since the web pages’ content was incorporated directly into the html pages. In this time period, desktop computers were mostly used to access the Internet.
2005 – present
Web 2.0, commonly referred to as the dynamic web, can be compared to the dynamic web before more companies began using the Internet. Data grew more dynamic, and backend databases started to develop and be used. The idea of centralised servers developed, and cloud computing finally took control. Today, this still occurs. Almost every organisation is moving its data and apps to public, private, and hybrid clouds at this time since we are in the era of clouds.
The current, responsive web of today is compatible with all types of web-enabled devices, including computers, servers, tablets, smartphones, IoT, and several more smart gadgets like smart homes and cars.
The Social Web, often known as Web 2.0, enhanced the social and interactive aspects of the Internet. Apps like Facebook, Instagram, and Twitter allow users to interact and converse with people all over the world in addition to consuming content.
Video streaming, interactive photographs and graphics, and dynamic video material that is presented based on the user’s interests and choices are all part of the Web 2.0 era. Nearly 4 billion people worldwide use sites like YouTube, Netflix, and many others to watch videos.
Cloud computing was not the only technology introduced by Web 2.0; there was also serverless, AI, ML, microservices, containers, APIs, interoperability, speech enabled systems, voice apps, and many others.
Front end technologies like WebAssembly, ReactNative, and several others are still being developed as part of the ongoing evolution of Web 2.0.
Gavin Wood, a co-founder of Ethereum, first used the term Web3 in 2014. The main idea behind Web3 is the use of decentralised blockchain-based platforms to offer consumers ownership over their data and store it on a blockchain. However, in my opinion, Web 3.0 will encompass much more than just blockchain.
The Web 3.0 age is approaching doors for its own reasons, even as Web 2.0 continues to prosper.
The Web 2.0 period is its golden age, but it has also brought with it numerous issues and challenges. Let’s look at a few of these challenges.
(i) Data Trust, transparency, privacy, and privacy centralization of data management
(ii) Centralized Power
(iii) The majority of data in Web 2.0 is kept on centralised servers and open clouds. Data became more susceptible to fraud, cyberattacks, and other errors as a result.
(iv) Management of personal data
Key Features of Web 3.0
1. Semantic Web
The Semantic Web, written by Sir Berners-Lee for Scientific American in May 2001, is a crucial component of Web 3.0. (Berners-Lee et al.) The Semantic Web, according to this source, “is an expansion of the current web in which information is given well-defined meaning, improving the cooperation of computers and people.” Here is a drawing that clarifies what the phrase “semantic web” means.
Data is stored everywhere in the Web 2.0 era, and numerous methods are being developed to make sense of the data. Data will be kept in the Web3 concept as information (meaningful data), making it simple to comprehend and work with both people and machines.
Omnipresence, often known as ubiquity, refers to being present everywhere. The systems are supposed to be accessible from anyone and everywhere in the Web3 idea. With the aid of technologies like decentralisation, edge computing, offline accessibility, and other technologies, this is an expansion of existing software systems.
3. AI & Machine Learning
An additional crucial component of Web3 is AI and machine learning. It is the logical career for modern systems, where automation is expanding with the aid of AI and ML.
Blockchain-based decentralised networks are expanding incredibly. Systems that are distributed and decentralised do not rely on a centralised authority or storage. The network is controlled by operator nodes, which can be located anywhere in the world and run on a peer-to-peer protocol.
Web 3.0 Applications
Wolfram Alpha wants to be a top Web 3.0 application by 2022. It is a Wolfram Research product that provides a computational knowledge engine to aid in the visualisation of the data acquired from internet databases. Instead than listing websites like a search engine, it is utilised to provide direct answers. It can provide you with better information in less time than even Google Search Engine because to the inventiveness of the expertise.
2. Siri ,Google Assistant and Alexa
The semantic web is used by the voice assistants from the top three tech companies in the world: Google Assistant, Alexa, and Siri. Users using this programme can now perform tasks they were before unable to perform thanks to voice recognition and natural language processing. These assistants can now respond to a wide range of queries from their users.
Flickr is a website for photography and photo sharing that enables users to find, create, post, and share photographs with people they care about. Flickr has one of the largest public databases with billions of photographs organised into thousands of categories and over 17 million active visitors each month.
4. Facebook/ Meta
It would be the most populous country in the world if it were a country. Facebook and Instagram, the two most popular social networking sites from the Meta, are having a daily impact on users’ lives and are expanding their reach tremendously. With the use of Web 3.0 technologies, users discover and establish new communities and connections. Customer involvement and engagement are further increased via apps created around the Facebook ecosystem.
Web 3 is here to stay, and there’s no denying that our educational system needs to change quickly to keep up with students’ changing needs and the skills they’ll need to succeed in the future. But as our educational system changes to keep up with the Web 3, we are confronted with challenging open questions about security, privacy, and addiction as we start to adopt real-world Ed 3 solutions. It is imperative to avoid falling into the myth that technology will be the panacea for all of our current educational problems; it never has been and never will be.
Hopefully, a smarter web and a more individualised web browsing experience will lead to a more equitable internet. The most important aspect of Web 3.0 will be user empowerment since they will have control over their data.
More sectors will be impacted by AI, ML, IoT, and associated technologies as the momentum behind dApps (decentralised applications) and DeFi (decentralised finance) grows.
