Where Bitcoin focuses on being money, Ethereum is closer to a shared world computer: developers deploy code that runs exactly as written, powering everything from stablecoins to DeFi and NFTs.
Ethereum secures itself with proof of stake, where validators lock up ETH rather than burning energy. It is the second-largest crypto asset and the backbone of much of the wider ecosystem.
