Web 3.0, another buzzword flying around these days; Web 3.0 or Web3 is the third iteration of the World Wide Web (the internet).
There has been a progression in internet iteration since the 1990s, starting from Web 1.0 to Web 2.0 and now Web 3.0.
Web 1.0 (1990-2005)
Web 1.0, also called the Static Web. It is the earliest version of the internet that emerged in the 1990s; it was read-only and pretty simple as it offered limited information with little or no user interaction. It was composed of web pages joined by hyperlinks without the visuals, controls, and forms we see today.
Berners-Lee, a computer scientist at European researcher CERN, pioneered the internet’s early growth in 1990. He wrote the three fundamental technologies that have become the foundation of the web (HTML, URL, HTTP) and the first web page browser/editor (WorldWideWeb.app).
Web 2.0 (2005-Present)
Web 2.0 is the second stage of internet development, characterized primarily by the shift from static web pages to user-generated content and the growth of social media. It is also known as the Social Web; it introduced frontend technologies like Javascript and backend technologies like PHP. This allowed developers and startups to build dynamic interactive websites like YouTube, Instagram, and many more.
Web 2.0 also allows user-generated content to be viewed by millions of people around the world virtually, instantly, and simultaneously.
Web 3.0 (Infancy Stage)
Web 3.0 is the next iteration of the internet. It is based on decentralization and blockchain technology. It is said to create a more intelligent internet that will process information with human-like intelligence through Artificial Intelligence systems that run smart programs to assist users.
The term ‘Web3’ was introduced by Polkadot founder and Ethereum co-founder Gavin Wood in 2014. The concept recently gained popularity and interest in 2021 from technology companies and crypto fanatics.
Fundamental Features of Web 3.0
AI and Machine Learning
AI is the stimulation of human intelligence practices by machines and computers, e.g., speech recognition, self-driving cars, smart assistants, manufacturing robots. In Web 3.0, computers will process data like humans through natural language processing and semantic web concepts.
Also, Web 3.0 will use data and algorithms to imitate how humans learn. This will make computers produce more relevant, tailored, and faster results in diverse industries.
Ubiquity and Connectivity
Ubiquity means having the ability to be present everywhere and at the same time. Web 3.0 promises that information and content will be more interconnected and present everywhere; multiple applications and devices will easily access it; an example is the Internet of Things, Smart Cities.
Decentralization
Decentralization is the transfer of decision-making and control from a centralized entity (individual, organization, or group thereof) to a distributed network. This is a core principle of Web 3.0 because the information is based on content and could be stored in multiple locations simultaneously and hence be decentralized.
Spatial Web and 3D Graphics
Web 3.0 aims to blur the line between the physical and digital world by revolutionizing graphics technology, bringing three-dimensional (3D) virtual worlds into clear focus. 3D graphics bring a unique immersion level in gaming applications like Decentraland and real estate, health, e-commerce, and other industries.
