What is Web3.0?

The 3rd generation of web development and design is referred to as Web3.0. It utilizes artificial intelligence (AI), machine learning (ML), and blockchain technology to allow real-time interpersonal interactions. Web3.0 is a decentralized ecosystem that runs on a blockchain platform. In this platform, users are in complete control of their data. Web3.0 applications are developed based on decentralized protocols such as Ethereum, IPFS, and Filecoin. These protocols offer better user experience and security and are efficient as they don’t rely on central servers. Some of the Web3.0 applications are Bitcoin, Augur, MetaMask, uPort, etc.

Features of Web3.0

The following are the important aspects of Web3.0 technology:

  • Web 3.0 applications make use of the blockchain technology. Through blockchain, the data is stored in a distributed ledger that is immutable and secure. This implies that the data can be shared without permission from the central authority, making it difficult for hackers to snatch or tamper with any data.
  • Use of smart contracts, which are digital contracts that self-execute when the prescribed conditions are met. This ability can automate many tasks making transactions much more efficient.
  • We3.0 allows decentralization, which means there is no central point for failure or control. Instead, the authority is distributed across different nodes making the applications less prone to hacking and data leaks.
  • Web3.0 lays strong emphasis on privacy and security. Why is this crucial? There has been a tremendous rise in data breaches in recent times, making it imperative to protect user data. Web3.0 makes use of advanced encryptions and other security measures to protect user data.

Key design principles for creating a Web3.0 ecosystem?

Some of the key design considerations for creating a Web3.0 ecosystem are:

  • Decentralization: Usually, web applications are designed as centralized systems, with a central server that holds the data and logic together. However, in the Web3.0 ecosystem, there is no central server in place. Here, the data and application are distributed through a node network. This approach boosts security and resilience since there is no single point of failure. Decentralization can be achieved through various blockchain protocols such as IPFS, Filecoin, and Ethereum.
  • Immutability: In a Web3.0 ecosystem, data is immutable, which means it cannot be modified or deleted. It is possible due to an extensive use of Distributed Ledger Technology (DLT) like Blockchain. Immutability ensures the data is tamper-proof and trustworthy.
  • Interoperability: Web3.0 ecosystems are developed as interoperable, which means they can interact with each other. It is possible due to open standards and protocols. Interoperability supports the development of a true decentralised network in which data and applications flow freely between different platforms.
  • Security: Web3.0 ecosystems are designed to keep security as the primary objective. It is achieved through the use of cryptography and digital signatures. Full-proof security ensures there is no unauthorized access and tampering of data.
  • Privacy: Web3.0 ecosystems are developed to fully respect user privacy. It is made possible with encryption & anonymity technologies. The privacy aspect allows users to control the data and decide who can access & use it.

Skills needed for becoming a Web3.0 developer

Web3.0 technology is still evolving, and there is a lot of scope in terms of improvement and tapping its full potential. As a result, the following skills need to be acquired by Web3.0 developers to build the applications and infrastructure to power Web3.0 ecosystem.

  • Thorough knowledge of Blockchain technology & developing dAppsFirstly, Web3.0 development requires you to be well-versed in blockchain technology. The developers need to understand how Distributed Ledger Technology (DLT) systems operate and also build smart contracts and applications to run on them. As the Web3.0 ecosystem develops further, demand for Web3.0 developers will also rise. Those IT developers who are able to build innovative dApps & frameworks will be in high demand among businesses and organizations that are involved either in the development or implementation of Web3.0 technologies.
  • Excellent cryptographic knowledge: Web3.0 developers need to have a strong command of cryptography which is a key technology used for securing data in Web3.0 ecosystems.
  • Web development expertise: To be a successful Web3.0 developer, a thorough understanding of blockchain technology along with web development is crucial. They must know how to develop and deploy web applications. Additionally, Web3.0 developers should have good experience with programming languages like JavaScript, CSS, and HTML.
  • Capable of collaborating: To successfully build and implement Web3.0 applications, a strong collaboration between stakeholders, developers, designers, users, etc.., is essential. Web3.0 developers must be able to work in a team environment and share good communication with each member of the project team.


Web3.0 is the future of the Internet and will continue to grow and get better at the same time. In the future, there will be a radical demand for skilled Web3.0 developers who have deep knowledge of building dApps on blockchain platforms. As we are observing more and more hacking and other illegal cyber-criminal activities, building decentralized web and mobile applications is imperative if we have to protect user data. Hence, acquiring the skills for Web3.0 innovation will provide the required impetus to build the next generation dApps and protect user data and privacy.


Is Web3.0 only associated with Ethereum?
Web3.0 is a collective phrase used for decentralized web applications. It is mostly associated with Ethereum or IPFS, but not restricted to only these applications. Web3.0 is also associated with Polkadot, Solana, Kusama and Substrate apps. In a nutshell, Web 3.0 stands for any application that has no single point of failure or control.

What is a Decentralized Application (dApp)?
In layman’s terms, a decentralized application or dApp is an application run by several computers through a peer-to-peer network instead of a single computer. dApps are powered by blockchain technology which is a distributed ledger technology (DLT) that enables transparent, secure, and tamper-proof transactions.

Should we learn back-end development to pursue a Web3.0 developer career?
It depends on the specific goals and interests in the Web3.0 field. If you have a desire to build dApps, then learning both back-end and front-end development is critical. However, if you are only working on developing UI and backend logic, then you can concentrate only on specific areas.

What are smart contracts?
Smart contracts are agreements or digital contracts between two or more parties that are executed automatically when specific conditions are met. These smart contracts are created on the blockchain platform, which is a secure, distributed, and transparent ledger.

How to connect dApp to the front-end?
There are multiple ways to connect a dApp to the front-end, but the most popular options are Web3.js and Ethers.js.

How does a blockchain work?
A blockchain is secured by mathematics and specifically through a hash function. A hash function allows input of any size and converts it into an output of fixed size. The hash function creates a unique fingerprint for each block which protects the content from being modified.

What is a Web3.0 semantic web?
A Web3.0 semantic web combines information in such a way that both humans and computers are able to comprehend. It is a combination of Semantic Web and Artificial Intelligence.
