Web3 Explained: How Does Web3 Work?
Web3 works using blockchain networks and smart contracts.
Let’s break it down step by step.
Step 1: Blockchain Stores Data Securely
First, Web3 uses blockchain instead of centralized servers.
Blockchain records information across multiple computers, making it transparent and secure.
Step 2: Smart Contracts Run Applications
Next, smart contracts automate agreements and transactions.
For example, a DeFi app can lend money without a bank using smart contract code.
Step 3: Digital Wallets Replace Passwords
In Web3, users log in using crypto wallets instead of email/password.
Popular wallets include:
- MetaMask
- Trust Wallet
- Coinbase Wallet
As a result, users control their identity directly.
Step 4: Decentralized Apps (dApps) Power Web3
Web3 platforms run on decentralized applications instead of company-owned servers.
Examples include:
- Uniswap (DeFi)
- OpenSea (NFTs)
- Lens Protocol (Social Web3)
Step 5: Tokens Create Digital Ownership
Finally, Web3 introduces tokens and NFTs that represent ownership.
Therefore, users can own:
- Digital art
- In-game items
- Governance rights
