Ethereum (ETH) is a leading cryptocurrency and blockchain platform known for its smart contract capabilities. Launched in 2015, Ethereum allows developers to build decentralized applications (dApps) and is widely used in the world of decentralized finance (DeFi), NFTs, and gaming. Unlike Bitcoin, which is mainly used as digital currency, Ethereum offers a more versatile platform for various blockchain-based services. Its native token, ETH, is used to pay for transactions and services on the network. In 2022, Ethereum upgraded to a proof-of-stake system through an event known as "The Merge," which reduced its energy consumption significantly. Ethereum’s flexibility, active development community, and wide range of use cases have helped it maintain its position as the second-largest cryptocurrency by market value.
