What is Web 3.0?

“Web 3.0, also known as Web 3, is the third generation of the World Wide Web. It is a concept that is dictating the Internet’s future, where there will be a strong emphasis on a decentralized ecosystem built on blockchain technology. Web 3 is the next step in the evolution of the Internet, which will utilize AI and blockchain technologies to process information and data with near-human intelligence, leading toward an open, secure, trusting, and permissionless network.”

Evolution of the World Wide Web

The World Wide Web is a part of the Internet that is responsible for connecting all the public websites and application services that users interact with. The first stage, known as Web1.0, allowed its users to access information on multiple pages without providing them with an opportunity to interact or edit information and was strictly read-only. It started in 1991 and ended in 2004.

Web 2.0 succeeded Web 1.0 and is still in use. It places a strong emphasis on content that is created by users and allows them to have a direct impact on what’s being shown on a certain website. It revolutionized information sharing by allowing user interaction to shape the displayed content. All social media apps are prime examples of Web 2.0.

Web 3.0 is in its initial phase, where it’s still evolving and developing. The definition is constantly getting updated to fulfill the needs of the present and future. Transitioning from Web 1.0 to Web 2.0 took about a decade, and the same amount of time can be expected to transition from Web 2.0 to Web 3.0.

How Does Web 3.0 Work?

Hypertext Markup Language (HTML) is the foundation layer for all three World Wide Web technologies. HTML is associated with the design, layout, and delivery of web pages. The feature that distinguishes Web3.0 from other versions is how it connects with different data sources.

Most of the websites and applications on Web 2.0 rely on a centralized database for running the functionality and delivering the data. What’s different about Web 3.0 is that it will focus on a decentralized blockchain for running web applications. In a decentralized blockchain network, there won’t be any central authority, and all users will collectively hold control.

Web 3.0 is also said to incorporate the feature of paying for goods and services via a decentralized form of payment using various crypto-currencies like bitcoin, etc.

Let’s dive into some of the features and applications of Web3.0 that will be revolutionary for the Internet.

Important Features of Web 3.0

The main features of Web3.0 are listed below:

  • Decentralization
    Unlike Web 1.0 and Web 2.0, where the applications and payment methods were largely centralized, Web 3.0 will be independent of any central governing authority.

  • Permissionless and Secure
    Since Web 3.0 will be blockchain-based and decentralized, it will offer more security than the earlier version of the World Wide Web. Applications and services will run in a more distributed approach, removing any central authority that controlled the whole process earlier. In this way, you will not need to connect with one another in the presence of a third party. This feature will make Web 3.0 fully permissionless.

  • Blockchain Friendly
    Being blockchain-friendly, Web 3.0 will allow the use of cryptocurrency. This will surge the demand for different cryptocurrencies and replace the use of fiat currency.

  • Autonomous and Automated
    Web 3.0 will incorporate state-of-the-art technologies like AI, Machine Learning, Natural Language Processing, etc. With these technologies, the whole Web 3.0 will be autonomous, and computers will be able to comprehend information and data with the highest levels of artificial intelligence.

  • Data Ownership
    In today’s world, the data that is being generated by us every second is used by big companies and corporations. With Web 3.0, the data ownership will be within the control of the user, allowing them to choose and sell their data to corporations and earn from it. This feature of Web 3.0 makes it more secure and trustable among users.

Applications of Web 3.0

Web3.0 has numerous applications and services due to the implementation of blockchain technology. Some of these applications are:

  • Cryptocurrency
    The base of Web 3.0 is built on the concept of blockchain. Cryptocurrencies like Bitcoin and Etherium are blockchain-based and now form a new payment method. Some of the other benefits of cryptocurrencies include cheaper and faster transactions, decentralized nature, stronger encryptions, etc.
  • dApps
    DApps stands for “Decentralized Applications”. These are similar to software programs that run on decentralized networks rather than centralized ones. These applications are never under a 3rd party authority, and each transaction is fully verified and secure.
  • NFTs
    NFT stands for Non-Fungible Token. It allows for digital products to receive identity in the form of tokens that can be stored in blockchain with a unique cryptographic hash. This provides value to virtual products like art, items, etc.
  • Artificial Intelligence
    Web 3.0 will incorporate next-generation technologies like artificial intelligence (AI) and machine learning to achieve near-human intelligence. This feature of Web 3.0 can be used for multiple tasks like advertisement recommendations, movie recommendations, and human-like robot assistants.
  • Messaging
    Messaging has become an absolute must for us in our daily lives. A lot of communication is carried out via messaging/texting. Currently, your messages are not secure and can be tracked down by governmental offices, hackers, and data-stealing companies. This can be stopped and avoided using Web 3.0 because of its decentralized nature. E-Chat, Obsidian, and YSign are a few examples that show what messaging apps will look like in the future.


Suffice it to say that Web 3.0 is inevitable and here to stay. With Web 3.0, the Internet and online web services will become more personal and customizable. The decentralized nature of Web 3.0 will also allow us to pave the way for a more equitable and autonomous web that will empower ordinary individuals to keep control of data and transactions without the involvement or influence of any third party.
