Ethereum (ETH) has solidified its position as a cornerstone in the blockchain ecosystem since its inception in 2015. Serving as the native cryptocurrency of the Ethereum network, Ether is pivotal for transaction fees and as collateral for network validators. The platform's versatility has spurred the development of decentralized applications (dApps), decentralized finance (DeFi) protocols, and non-fungible tokens (NFTs), fostering a vibrant digital economy. A landmark transition to a Proof-of-Stake consensus mechanism in September 2022 significantly reduced Ethereum's energy consumption by over 99%, underscoring its commitment to sustainability. As of February 2025, Ethereum's circulating supply stands at approximately 120 million $ETH , with its price experiencing fluctuations influenced by market dynamics and ongoing technological advancements.
