Ethereum Explained Simply
If Bitcoin is digital gold, Ethereum is a digital computer that anyone can use.
What Does Ethereum Do?
Ethereum is a platform for building applications that run without a central authority. These "smart contracts" automatically execute when conditions are met — like a vending machine that handles complex financial transactions.
Real-World Uses
- DeFi: Borrow, lend, and trade without banks
- NFTs: Digital ownership certificates
- Stablecoins: Dollar-pegged tokens (USDC, DAI)
- DAOs: Community-governed organizations
How ETH (the Token) Works
ETH is the fuel for Ethereum. Every action on the network requires a small ETH payment called "gas." The more complex the action, the more gas needed. Check current costs with the Gas Estimator.
Staking
Since 2022, Ethereum uses Proof of Stake. You can stake ETH to help secure the network and earn ~3-5% APY. Calculate your potential earnings with the Staking Calculator.
Layer 2 Solutions
Ethereum can be expensive during busy periods. Layer 2 networks (Arbitrum, Optimism, Base) offer 90-99% cheaper transactions. Compare fees with the L2 Fee Comparison.
