Ethereum
A decentralized blockchain platform that runs smart contracts and applications, using ether (ETH) to pay for network activity.
Ethereum is a decentralized blockchain platform designed to run smart contracts: programs that execute automatically when their conditions are met. Its native cryptocurrency, ether (ETH), is used to pay transaction fees and compensate the network participants who help secure and process activity. Unlike Bitcoin, which is mainly built around transferring and storing digital value, Ethereum is intended as a general-purpose computing network for blockchain-based applications.
Ethereum matters because it provides shared infrastructure for many parts of the crypto ecosystem, including decentralized finance, NFTs, stablecoins, DAOs, and token launches. For example, a lending app on Ethereum can let users deposit crypto and borrow against it without relying on a traditional bank, with the rules enforced by smart contracts. This flexibility makes Ethereum a base layer for many projects, though users still need to understand fees, wallet security, and smart contract risks.
