The notable challenges in the existing web are, 

  • Centralization is the foremost issue that can drive the expansion of new technologies like web 3.0 & IoT in future. The existing model of the web follows a centralized approach in which behavioral data of users is locked in silos. Big companies own your data and could sell them off to the highest bidder. 
  • Have you been bothered by an irrelevant ad while browsing through the internet? Well, the existing web definitely has little to show for privacy and security. Massive amounts of data captured in data centers are the easiest targets for cybercriminals. 
  • The emphasis on technology disruptions like Internet of Things and web 3.0 also emerges profoundly from the pressure on existing infrastructure of the web. As billions of connected devices generate larger data sets, the existing client-server model cannot scale up to the demand of next-generation web. 

Web 3.0 could easily help in resolving these issues by ensuring the following interventions.

  • The transition to web 3.0 would take away the oligopoly market dominated by social media giants. 
  • Introduction of web 3.0 & IoT platforms would also help in dissolving the boundaries between physical world and digital content. 
  • Most important of all, web 3.0 resolves the concerns of centralization and places ownership of personal data in the hands of users. At the same time, it can also facilitate data transfers with privacy in systems focused on security and confidentiality. 

However, web 3.0 would need the support of relevant technologies for offering the core principles of openness and sharing. Internet of Things will be one of the crucial attributes in the development of the web 3.0 infrastructure.

The notion of comparing web 3.0 and IoT can be a bit confusing for many, considering the fact that IoT itself is a web 3.0 technology. However, a comparison between Internet of Things and Web 3.0 is important to understand how they fit together. Here is an outline of the differences between web 3.0 and IoT on the basis of different factors. 


If you want to compare IoT and web 3.0, there could be no better place to start than the definitions. The definitions of two terms you are comparing can help you understand what they are and perceive the fundamental difference between them. 

Web 3.0, in the broadest sense, is actually the third stage in evolution of the infrastructure of internet. The web 3.0 infrastructure would focus profoundly on developing a detailed understanding and analysis of data for creating a semantic web. Basically, web 3.0 focuses on creating an open, connected, and intelligent website with better user experiences. 

The other player in the web 3.0 & IoT comparison, i.e., IoT, is basically a network of physical “things.” The “things” in the Internet of Things refer to physical objects embedded with sensors, software, and other technology integrations. IoT objects embedded with sensors can connect and exchange data with other connected devices and systems through the internet. The sheer range of IoT devices varies from common household objects to advanced industrial tooling. Estimates suggest that the total number of connected IoT devices will reach almost 22 billion by the year 2025.

You can also develop a solid comparison between Internet of Things and web 3.0 by reflecting on their objectives. What purpose do web 3.0 and IoT serve? The objective of web 3.0 focuses primarily on empowering users with an improved emphasis on security, privacy, and trust. As a matter of fact, the primary objective of web 3.0 rests in realizing the actual vision for the internet. It aims to democratize the internet and allow users to regain ownership and control over personal data. 

The basic objective of Internet of Things is also another highlight for the web 3.0 & IoT comparisons. Internet of Things basically aims at creating a network of connected devices with embedded technologies that enable data identification and collection. However, the actual objective of IoT does not revolve around connection of IoT-enabled objects or the development of embedded technologies. On the contrary, IoT focuses on leveraging insights from data obtained by IoT-enabled devices for automation, digitization, and optimization of many digital transformation processes. 

The role of IoT and web 3.0 in facilitating digital transformation is obviously the common element between them. Objectives of web 3.0 focus on democratization of the internet and allowing control of data to users. On the other hand, IoT focuses on using data for driving better decisions in digital transformation.
