Web 3.0, a concept often hailed as the next frontier of the internet, is set to revolutionize our online experiences. At the heart of Web 3.0 lies the Web 3.0 stack, a suite of technologies and protocols that will redefine how we interact with the digital world. To grasp the significance of the Web 3.0 stack, it’s essential first to understand what Web 3.0 is and why it is so important.

Web 3.0: A Vision of a Decentralized Internet

Web 3.0, in its essence, represents a paradigm shift in the way we approach the internet. It is an ambitious vision for a decentralized internet that is based on blockchain technology. Gavin Wood, co-founder and CEO of Parity Technologies, succinctly describes Ethereum, one of the prominent platforms in the Web 3.0 space, as a decentralized platform that leverages blockchain technology to manage and execute contracts. The key idea behind Web 3.0 is to create a more user-centric and decentralized Internet.

Web 2.0, the current phase of the internet, introduced us to the era of user-generated content, social media, and interactive websites. However, it is centralized in nature, and users often grapple with issues like data breaches, vendor lock-in, poor user experience, and the dominance of tech giants. Web3 aims to address these challenges by decentralizing power, enhancing data security, and providing more reliable services.

The Building Blocks of the Web 3.0 Stack

To understand the Web 3.0 stack, we need to delve into the core components that make it all possible. These components work in harmony to create a decentralized web that is both secure and user-centric:


Blockchains serve as the foundation of the Web 3.0 stack. A blockchain is a digital ledger of transactions maintained by a peer-to-peer network of nodes. This ledger records not only financial transactions but also on-chain data, including account balances and smart contract codes. Blockchains ensure transparency and security by their decentralized nature.

Smart Contracts

Smart contracts sit just above blockchains in the Web3 stack. These self-executing computer programs run on the blockchain and automate complex transactions and contracts. They are crucial for the functioning of Web3 applications. Smart contracts are immutable, meaning their code cannot be changed once deployed, ensuring trust and reliability.


Nodes are integral to blockchain networks. They are the individual computers that make up the network, verifying transactions and maintaining the blockchain. Nodes play a crucial role in parsing on-chain data and interacting with smart contracts, making them a bridge between users and the blockchain.

Infrastructural Primitives

Beyond the basic infrastructure of blockchains, smart contracts, and nodes, the Web3 stack also relies on infrastructural primitives like decentralized file storage, data feeds, and identity management. These elements are crucial to safeguarding data and ensuring the reliability of Web3 applications.

Frontend Libraries

Every application, whether traditional Web 2.0 or Web 3.o, has a front end that provides the user interface and user experience. Web3 applications often use front-end libraries similar to those used in traditional web applications. However, the key difference lies in how they communicate with the backend, as Web3 applications are built on a unique architecture—the blockchain.

Communication Endpoints

Standard web applications use web servers to provide content and services, communicating with client devices through HTTP (HyperText Transfer Protocol). Web 3.0 applications, due to their blockchain foundation, require different communication protocols, such as P2P (Peer-to-Peer) networks. These networks of interconnected computers function as mini-servers on the blockchain.

Access Points: Browsers and Wallets

For users to interact with Web 3.0 applications, specialized tools are necessary. Web 3.o browsers and wallets serve as gateways for users to connect with decentralized applications.

Web 3.0 Browsers

While most blockchain applications are accessible as web apps, standard web browsers, like Google Chrome, cannot interact with these applications due to the unique nature of the blockchain. Users rely on specialized Web3 browsers like Brave, Status, or Opera or browser extensions such as MetaMask. These tools provide native support for parsing blockchain data and enable users to read and write transactions from their browsers.


Wallets are essential for interacting with Web 3.0 applications. They store cryptocurrency and facilitate transactions by signing with a private key. Sending transactions, including interactions with smart contracts, typically incurs a fee that goes to miners who execute these transactions. Wallets play a critical role in managing and sending cryptocurrencies.
