$ETH Ethereum (ETH) is a decentralized platform leveraging blockchain technology to power a wide array of applications beyond just cryptocurrency. Launched in 2015, it's known for its smart contract functionality, enabling developers to build decentralized applications (dApps) for various use cases like decentralized finance (DeFi), gaming, and more.

Unlike Bitcoin, which primarily functions as a digital currency, Ethereum is designed as a programmable blockchain. Its native cryptocurrency, Ether (ETH), fuels the network and is used to pay transaction fees, known as "gas." Ethereum operates using a proof-of-stake consensus mechanism, enhancing its efficiency.

Currently, Ethereum is the second-largest cryptocurrency by market capitalization. Its price fluctuates based on market demand, technological advancements, and adoption rates within the growing Web3 ecosystem. Recent data shows ETH trading around $1,800, reflecting a dynamic and evolving market.
