Ethereum (ETH) is the second-largest cryptocurrency by market capitalization and the world's leading programmable blockchain platform. Created by Vitalik Buterin and launched in 2015, Ethereum introduced smart contracts — self-executing programs stored on the blockchain that automatically enforce the terms of any agreement.
Ethereum's ecosystem powers the majority of DeFi (Decentralized Finance) protocols, NFT marketplaces, and Web3 applications. Major protocols built on Ethereum include Uniswap, Aave, Compound, MakerDAO, and thousands of others. After The Merge in September 2022, Ethereum switched from Proof of Work to Proof of Stake, reducing its energy consumption by ~99.95%.
Ethereum's Layer 2 ecosystem — including Arbitrum, Optimism, Base, and zkSync — significantly reduces transaction costs and increases throughput. These solutions process transactions off the main chain and settle them on Ethereum for security, enabling fast and cheap transactions while maintaining Ethereum's security.
