Ethereum: The Smart Contract Platform
Ethereum is the blockchain platform that pioneered smart contracts and hosts most decentralized applications. It's like the operating system for programmable money and decentralized apps.
Ethereum is a decentralized blockchain platform that enables smart contracts and serves as the foundation for thousands of decentralized applications (dApps). It introduced programmable money and became the backbone of DeFi, NFTs, and Web3.
How Ethereum Works
Smart contract execution through the Ethereum Virtual Machine (EVM) that runs code automatically when predetermined conditions are met.
Gas fee system requires users to pay for computational resources used by transactions and smart contract operations.
Proof-of-stake consensus secures the network through validators who stake ETH and earn rewards for honest participation.

Real-World Examples
- DeFi protocols like Uniswap, Aave, and Compound that revolutionized decentralized finance
- NFT marketplaces including OpenSea and Foundation that created digital collectible ecosystems
- Stablecoins such as USDC and DAI that provide price stability within the Ethereum ecosystem
