$ETH
Ethereum (ETH) is a decentralized, open-source blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and others, Ethereum revolutionized blockchain technology by introducing programmability through its Ethereum Virtual Machine (EVM). Ether (ETH) is the native cryptocurrency used to pay for transactions and computational services on the network. Ethereum has undergone significant upgrades, including the transition from Proof of Work (PoW) to Proof of Stake (PoS) through Ethereum 2.0, making it more energy-efficient. It remains one of the most widely used and influential platforms in the crypto space.
