Ethereum ($ETH) is a decentralized blockchain platform that enables smart contracts and decentralized applications (DApps). Launched in 2015 by Vitalik Buterin and others, it introduced programmability to blockchain technology. Ether (ETH) is its native cryptocurrency, used for transactions, staking, and paying gas fees. Ethereum transitioned from Proof of Work (PoW) to Proof of Stake (PoS) with the 2022 Merge, improving energy efficiency and security. It powers DeFi, NFTs, and Web3 innovations. With ongoing upgrades like sharding in Ethereum 2.0, it aims to enhance scalability and reduce fees, solidifying its position as a leading blockchain ecosystem.
