The term ‘web’ can be applied to pretty much anything that requires internet access to fully operate – such as a website, webpage, and webcam. This is not surprising since ‘web’ is also one of the three components of the renowned World Wide Web

However, this prefix can also be applied to numbers – such as Web 2.0, which occupies a dominant status in the current era. We also have Web 3.0, which, despite being fairly new, is being widely utilized in specific areas and is, slowly but surely, replacing its predecessor. 

Web 2.0:

With Web 1.0, users could simply consume content. However, the second generation of the interoperable internet allowed users to go several steps further: alongside consuming content, users could now produce it and even share it with other internet users. 

Thus, web 2.0 ushered in the era of internet commercialization, where entire activities could be digitized. Without this Hail Mary, these activities – which include entertainment, media, advertising, banking, and retail – were on the cusp of death. 

Web 2.0 also allowed social networks to evolve into digital communication platforms through interactions like podcasts, blogs, RSS, and even tags that enabled users to find more relevant and useful content. Google, Apple, and Amazon are the prime examples of Web 2.0. 

Key Features of Web 2.0:

  • Ability to access internet material through multiple devices.
  • Dynamic content that has been designed to operate through a CTA mode. 
  • Users can now create their own content as opposed to simply consuming and responding to content. 
  • A controlling platform that regulates the dissemination of data.
  • API development for inter-program interaction. 

Web 3.0:

The third generation of the internet focuses on decentralization and getting rid of any middle person trying to control everything and everyone. Web 3.0 utilizes distributed ledger technology and encryption to do away with trust and security issues present in Web 2.0. 

However, alongside security and decentralization, another key feature of Web 3.0 is improved interaction through the use of AI (Artificial Intelligence). The introduction of AI is bound to modify or even completely change a number of established processes. 

Key Features of Web 3.0:

  • AI will help identify the most relevant information for internet users, and will therefore diminish the role of organic search results. 
  • Through Semantic Web, machines will be better able to interpret and understand human words, which will lead to better human-machine interaction.
  • Use of 3D graphics and images.
  • A unique layer of privacy and security brought about through blockchain technology. The absence of a control center will lead to freedom from surveillance and censorship. 

Pitfalls of Web 3.0:

  • The lack of centralized control will make it harder to address disinformation, hate crimes, cybercrimes, and other negative phenomena. 
  • The lack of control will also make it harder to determine which countries’ judiciaries should get involved in disputes. 
  • The Web 3.0 scalability is still not very significant, which can significantly reduce the processing speed. 

Web 3 Application – Examples of Real-Life Utility:


Since blockchain is the inspiration behind Web 3.0, it is just fair that it is the first example on this list. A lot of other Web 3.0 features and technologies are dependent on blockchain, so it is also essential to Web 3.0. 

The blockchain is a ledger that records transactions and exists on multiple computers throughout the world. Whenever a new transactional block is added to this chain, every database copy must be amended accordingly. Every transaction is publicly available and can be accessed by anyone interested. 

Attempting to meddle with the transaction records will corrupt the entire chain. Also, since validated database copies are spread throughout the internet, the blockchain is not controlled by a single authority. 


Although blockchain has a number of use cases, the most common of them is cryptocurrency. Cryptos are digital currencies that are not regulated by a central authority such as a government or a bank. 

Cryptocurrency makes use of blockchain to record the quantity of each currency and how the currency is distributed (who holds how much). 

 Decentralized Application:

A Google Doc is an example of a centralized application. This means that Google can access, view, and control all the information present in your documents. Against these privileges, Google allows us to store and share information through the cloud, free of cost. 

But what if you could enjoy these advantages without surrendering your information to a central authority? This is the idea behind decentralized apps, which are open-source, public, and secured using cryptography. This means that users can enjoy the benefits of cloud-computing applications while being in full control of their data. 

Final Word:

To sum up, Web 2.0 focused on creating communities, user-generated content, and the use of cloud computing. The main objective behind Web 3.0, meanwhile, is to use machine learning to provide a Semantic and data-driven web and offer more open and intelligent websites.
