This represents an iteration or phase in the evolution of the web/internet and represents a paradigm shift that may be as disruptive as Web 2.0. The core concepts of Web 3.0 are decentralization, openness, and greater utility for users.
Berners-Lee published a paper in 2001 that introduced the concept of the Semantic Web. Computers have no reliable way to process the semantics of language (i.e., figure out the actual context of a word or phrase). Considering the purpose of the Semantic Web, Berners-Lee wanted to create software that would facilitate sophisticated tasks for users and give structure to the content of web pages.
Web 3.0 has evolved far beyond Berners-Lee’s original concept of the Semantic Web from 2001. There are two reasons for this: One is that it is extremely expensive and difficult to convert human language-with all of its subtle nuances and variations-into a format that can be readily understood by computers, and the other is that Web 2.0 has already evolved substantially over the past two decades.
Web 3.0 Defining Features.
There is no standard definition of Web 3 but it does have a few defining features:
The main concept of Web 3.0 is this. Web 2.0 utilizes HTTP in the format of unique web addresses to find information stored on a fixed server. Which is usually on a single location. Since Web 3.0 will be able to find information based on its content, it can be stored in multiple locations simultaneously. And therefore be decentralized. Data generated by a wide array of new and increasingly powerful computing resources. These resources includes mobile phones, will be part of Web 3.
Decentralized data networks will enable users to sell devices like desktops, appliances, vehicles, and sensors. That ensures that users retain ownership of the products.
Trustless and permissionless:
Apart from decentralization and the use of open source software, Web 3.0 will also be trustless and permissionless . Here, trustless means so participants can interact directly without going through an intermediary. While permissionless means anyone can participate without prior authorization from a governing body. Thus, Web 3.0 applications will take advantage of decentralized peer-to-peer networks or blockchains a combination thereof-these applications called as decentralized applications or dApps.
Artificial intelligence (AI) and machine learning:
In Web 3.0, computers will be able to understand information similarly to humans, through technologies based upon Semantic Web concepts and natural language processing. Web 3.0 will also use machine learning. This is a branch of artificial intelligence (AI) that uses data and algorithms to imitate how humans learn, gradually improving its accuracy. These capabilities will enable computers to produce faster and more relevant results in a host of areas. For instance, drug development and new materials, as opposed to merely targeted advertising that forms the bulk of current efforts.
Connectivity and ubiquity:
With Web 3.0, information and content are more connected and ubiquitous, accessed by multiple applications. And with an increasing number of everyday devices connected to the web—an example being the Internet of Things.
