The internet has evolved dramatically since its inception, and we’re now on the brink of another major shift—Web3. This new era promises to decentralize power, return ownership to users, and reshape how we interact online. But what exactly is Web3? How does it differ from what we’ve known as the web for decades? Let’s explore this transformation step by step.
The Evolution of the Web: Web1, Web2, and Web3
To truly understand Web3, it helps to look back at how the internet evolved through previous stages.
Web1: The Read-Only Internet
Often referred to as the "read-only" web, Web1 spanned from the early 1990s to the early 2000s. It was a static, one-way information highway where websites served primarily as digital brochures. Users could view content but couldn’t interact with it or contribute their own.
Tim Berners-Lee’s invention of HTML, HTTP, URLs, and the first web browsers laid the foundation for this era. Think of company websites in the 1990s—simple pages with text and images, offering no comment sections, forms, or user-generated content.
Web2: The Interactive, Social Web
With the rise of social media and interactive platforms, Web2 emerged as the "read-write" phase of the internet. This is the web most of us know today—dynamic, participatory, and dominated by platforms like Facebook, YouTube, Instagram, and Twitter.
Users can now create content, leave reviews, share videos, and connect globally. However, this convenience comes at a cost: centralized control. A handful of tech giants own user data, monetize attention, and dictate platform rules—leading to growing concerns about privacy, censorship, and inequality.

Web3: The Decentralized Future
Enter Web3—an emerging vision of the internet built on blockchain technology. Unlike its predecessors, Web3 aims to be user-owned and decentralized. Instead of corporations controlling platforms and data, users own their digital identities, assets, and content through cryptographic ownership.
At its core, Web3 empowers creators, communities, and everyday users by removing intermediaries like banks, governments, and tech monopolies. This shift is powered by key technologies: blockchain, cryptocurrency, DeFi (decentralized finance), NFTs (non-fungible tokens), and play-to-earn gaming.
Blockchain Technology: The Backbone of Web3
What Is Blockchain?
Blockchain is the foundational technology behind Web3. In simple terms, a blockchain is a secure, transparent digital ledger that records transactions across many computers. Each transaction is grouped into a “block” and linked chronologically in a “chain”—hence the name.
Unlike traditional banking systems that rely on central authorities to verify transactions, blockchains use consensus mechanisms where multiple nodes (computers) validate activity. This makes the system trustless and resistant to tampering.
Imagine sending money without needing a bank—your transaction is verified by a global network instead.
Types of Blockchains
There isn’t just one blockchain—there are thousands. The two most prominent are Bitcoin and Ethereum, often called Layer 1 blockchains because they form the base infrastructure.
Other notable Layer 1 chains include Solana, Avalanche, Near, Fantom, and Flow. These networks support smart contracts and decentralized applications (dApps).
As demand grows on networks like Ethereum, transaction fees (known as gas fees) can skyrocket—sometimes exceeding $100 during peak times. To solve this, Layer 2 solutions like Polygon and Arbitrum have emerged.
Layer 2 blockchains process transactions off the main chain and bundle them before submitting them to the primary network. This reduces congestion and lowers costs significantly—making blockchain more accessible.
Cryptocurrency: The Native Currency of Web3
What Is Cryptocurrency?
Cryptocurrency refers to digital or virtual currencies secured by cryptography. They operate on decentralized networks using blockchain technology. Bitcoin was the first cryptocurrency, but today there are over 10,000 active cryptos and around 300 million users worldwide.
Crypto enables peer-to-peer transactions without intermediaries. It’s not just for payments—it powers entire ecosystems within Web3.
Bitcoin vs Ethereum: Two Sides of the Same Coin
While both are cryptocurrencies, Bitcoin and Ethereum serve different purposes.
- Bitcoin is often seen as “digital gold”—a store of value with a capped supply of 21 million coins.
- Ethereum, however, goes beyond currency. Its native token, ETH, fuels smart contracts and decentralized apps (dApps). Developers build NFTs, DeFi protocols, games, and more on Ethereum.
For example, the Bored Ape Yacht Club NFT collection runs on Ethereum. Their governance token, $APE, exists as an ERC-20 token on the same network.
Cryptocurrency vs Crypto Tokens
It’s important to distinguish between:
- Cryptocurrencies: Native coins of a blockchain (e.g., BTC on Bitcoin, ETH on Ethereum).
- Tokens: Digital assets built on top of existing blockchains (e.g., UNI on Ethereum).
Projects like Uniswap issue their own tokens ($UNI) to govern platforms or reward users—all made possible through Ethereum’s smart contract capabilities.

DeFi: Decentralized Finance for Everyone
What Is DeFi?
Decentralized Finance (DeFi) removes intermediaries from financial services. Using smart contracts on blockchains like Ethereum, DeFi allows anyone with an internet connection to lend, borrow, trade, and earn interest—without banks.
This opens financial access to unbanked populations and reduces reliance on traditional institutions.
How Liquidity Pools Work
Most DeFi platforms rely on liquidity pools—crowdsourced funds deposited by users (a process called staking). These pools enable automated trading on decentralized exchanges (DEXs) like Uniswap.
For instance:
- You want to swap USDC (a stablecoin) for ETH.
- You send USDC to Uniswap.
- The platform draws from a liquidity pool to give you ETH based on current market rates.
- The liquidity providers earn a portion of transaction fees as rewards.
This system replaces brokers and centralized exchanges with code-driven automation.
NFTs: Digital Ownership Redefined
What Are NFTs?
Non-Fungible Tokens (NFTs) represent unique digital assets stored on a blockchain. Unlike cryptocurrencies (which are interchangeable), each NFT has distinct properties—like a one-of-a-kind piece of art.
NFTs can represent:
- Digital art
- Music
- Virtual real estate
- In-game items
- Legal documents like deeds or certificates
Real-World Applications of NFTs
Beyond collectibles, NFTs are transforming industries:
Supply Chain Tracking
Companies use NFTs to track individual products across logistics networks. Each item gets a unique digital twin recorded on-chain—ensuring authenticity and reducing fraud.
Luxury Fashion
Brands like Louis Vuitton and Prada participate in the Aura Blockchain Consortium to verify high-end goods using NFTs. A handbag can come with an immutable digital certificate proving its origin.
Medical Records
Patients could own their health records as NFTs—granting permissioned access while preventing unauthorized data sales.
Real Estate
Property deeds are being “NFT-ified,” with ownership recorded immutably on blockchains. Some homes even come with metaverse-compatible digital twins.
Play-to-Earn Gaming: Earning While You Play
What Is Play-to-Earn?
Play-to-earn (P2E) gaming lets players earn real income through gameplay. Using NFTs and cryptocurrencies, gamers own their in-game assets and can sell or trade them freely.
This model has gained traction in regions with lower average incomes—most notably in the Philippines.
Axie Infinity: A Case Study in P2E Success
Launched in 2018, Axie Infinity became a global phenomenon. Players collect NFT creatures called Axies, battle others, and earn Smooth Love Potion ($SLP), a tradable cryptocurrency.
During its peak:
- Over $2 billion in sales were recorded.
- Top Axie NFTs sold for over $1 million.
- Filipino players earned more playing full-time than in local jobs—thanks to stable USD payouts.
Scholarship programs allowed experienced players to rent out Axies to newcomers—a win-win model driving adoption.
