ETH

Ethereum (ETH) is a decentralized, open‑source blockchain platform that enables the execution of programmable, tamper‑proof code known as smart contracts. Its core technology allows developers to build and deploy decentralized applications (dApps) spanning finance, gaming, supply‑chain, and other sectors, making it the foundational infrastructure for decentralized finance (DeFi) and non‑fungible tokens (NFTs). ETH functions both as a medium of exchange for transaction fees (gas) and as a staking asset within its proof‑of‑stake consensus mechanism, which secures the network and rewards validators. As the second‑largest cryptocurrency by adoption and developer activity, Ethereum is widely regarded as a cornerstone of the broader crypto ecosystem.
