The new era of computing has begun. You must have noticed that Internet technologies have evolved immensely for the past decade, becoming increasingly sophisticated and complex. The Internet of Things (IoT), 3d digital twins, blockchain, augmented reality, and other technologies have expanded opportunities so much that the old Web 2.0 term no longer describes the new Internet reality. Web 3.0 is now entering the vocabulary, even though there is still uncertainty about its meaning.

Experts believe that Web 3.0 makes Internet communication more transparent, decentralized, and efficient, meaning that it has immense potential for business, finance, governance, and other spheres. In an attempt to keep up with the fast technology development, this article seeks to define Web 3.0 and examine its role in online business.

By exploring Web 3.0 tools, characteristics, strengths, and Web 3.0 examples, we can better understand how its potential can be harnessed in different industries.

Understanding Web 3.0 

You probably wonder, “what is Web 3.0 technology?” Before you type “definition Web 3.0” into your search, let us explain this term. Due to the novelty of the concept, there is currently no unanimity as to how it should be defined. Web 3.0 is also called the Internet 3.0, and it normally refers to the third generation of Internet technology, which allows for more sophisticated and advanced interaction between devices and users.

Tim Berners-Lee, the WWW creator, was among the first to call Web 3.0 the Semantic Web, and these terms are still sometimes used interchangeably. Semantic Web refers to the system relying on machine-readable semantic data created with the help of RDF (Resource Description Framework) or XML (eXtensible Markup Language). The use of Web 3.0 to refer to Semantic Web allows highlighting the natural evolution of the Internet and its marketing value. 

Moreover, the most recent definitions of Web 3.0 mention its connection to the distributed ledger technology and blockchain, which is not surprising given its focus on authenticating and decentralizing information and the widespread adoption of these technologies. Although more efforts should be made to define Web 3.0, there are no doubts that this technology possesses immense potential in terms of efficiency, transparency, connectivity, and productivity. 

Evolution of Web: From Web 1.0 to Web 3.0

Web 3.0 did not emerge out of nowhere. The Internet evolved gradually over decades, transitioning from the passive to the interactive experience. The static, document-based Web has developed into an interactive and dynamic social space, which now allows linking documents, people, and data. So, what is Web 3.0 compared to Web 1.0 and Web 2.0?

What is WEB 3.0

Web 1.0

Web 1.0 was simple, static, and passive, especially compared to 21st-century Internet technology. Information, including text and images, was published in a static form, and no interaction with users and between users was possible. Until about 2000, users could only read information, employ search engines, and use simple e-commerce websites that allowed for little interaction with customers. Web 1.0 relied heavily on HTTP and HTLM protocols. The main characteristics of Web 1.0 can be summarized as follows:

  • Static pages
  • The use of simple Hypertext Mark-Up Language
  • Lack of dynamic representation 
  • Information created by experts
  • Standard languages

Web 2.0

Web 2.0 differed from Web 1.0 mostly in terms of creating, sharing, and interacting with the information. Web 2.0 transformed people from idle visitors to creators of the original content, which greatly affected business, marketing, and everyday life. Web 2.0 enabled unprecedented collaboration and interaction between users, companies, service providers, programmers, and organizations. As a result, businesses greatly benefited from its introduction, as it allowed enhancing the organizational processes while at the same time achieving better interaction with customers and improving the quality and diversity of services. The main features of Web 2.0 are as follows:

  • More interaction with less control 
  • User participation
  • Scalability
  • Flexible we design
  • Dynamic use and re-use of information
  • Information creation through greater user collaboration 
  • Business-focused 

Web 3.0

Web 2.0 vs. Web 3.0 comparisons usually miss the fact that Web 3.0 is not an entirely new invention but rather an extension and improvement of already existing Web 2.0 characteristics. Web 3.0 makes Internet content more diverse and accessible by allowing computers, not people, to generate new data. Introduction of new programming languages, the ability to draw information from a wider variety of sources, and the possibility of creating and sharing all types of data distinguish Web 3.0 from the older versions. Using advanced systems such as InterStellar Files System (IPFS), Web 3.0 creates a peer-to-peer file system that is faster and more efficient, secure, and transparent. Let’s dwell in more detail on the features of Web 3.0 technologies

Characteristics of Web 3.0

Semantic Web

The Semantic Web allows machines to decode meaning and emotions more effectively, enhancing user experience and facilitating connectivity. In other words, it utilizes Artificial Intelligence (AI) to enhance data processing.

3D Graphics and Spatial Web

3D graphics is another thing that distinguishes Web 3.0 from Web 2.0. The three-dimensional design allows creating a more realistic and engaging cyberworld, expanding business opportunities. Some industries, such as architecture, online games, real-estate, e-commerce, tourism, and others, have already incorporated 3D graphics to promote products and services. Spatial Web, in turn, is believed to be the future of Web 3.0, which will blur the line between the real and digital worlds. Some of its technologies, such as Virtual Reality, are already used in organizations and businesses to help users visualize objects and processes. 

Artificial Intelligence

AI technology has made Web 3.0 intelligent and more efficient. Today, machines can process text, audio, video, and photo content in a more meaningful way by establishing connections between different pieces of information. AI can separate valuable information from useless data and fake news from facts. It can also conduct client demand forecasting and personalized customer service, which are crucial for businesses.

Blockchain and Cryptocurrency

Description of Web 3.0 would be incomplete without clarifying its link with blockchain and cryptocurrency technology, which are currently reshaping the financial market. Blockchain helps address the main weaknesses of Web 2.0 by making Web 3.0 more transparent and secure and enabling absolute ownership and control of the data. How can a company use web 3.0 technologies to gain a competitive advantage? Well, the possibilities are endless and involve the use of defi solutions, tokenization, cloud storage, smart contracts, and other technologies to build trust and achieve greater efficiency. To take advantage of blockchain and learn about Web 3.0 blockchain potential, you can use 4irelabs consulting services.

Ubiquitous Connectivity

Next, 3.0 applications are characterized by ubiquitous connectivity. Information within Web 3.0 is more connected due to semantic metadata use, allowing data to be accessed anywhere, anytime, and by anyone. Fast connection speed, 5G, the Internet of Things, and other technologies help access information faster from various devices, making life more convenient. Take, for example, voice-activated virtual assistants that allow interacting with the data in a more meaningful and efficient way.
