DApp
Application operating autonomously on a blockchain.
Beginner-friendly explanation
A DApp is an application like a website or game, but it runs directly on the blockchain. No one can shut it down or control it alone. Example: Uniswap is a DApp that lets you swap cryptocurrencies.
Intermediate-level insight
A DApp uses smart contracts to manage its operational rules. It often interacts with wallets like MetaMask. Example: Aave is a decentralized lending DApp on Ethereum.
Advanced perspective
DApps must balance decentralization, scalability, and user experience. Some use Layer 2 solutions (Optimism, Arbitrum) to reduce fees and speed up transactions. Example: Sushiswap deploys its DApps across multiple blockchains to attract more users.
