$ETH Ethereum ($ETH) is the world's second-largest cryptocurrency, officially launched by programmer Vitalik Buterin in 2015. Unlike Bitcoin, Ethereum is not just a digital currency; it is a decentralized blockchain platform that supports the development and operation of smart contracts and decentralized applications (DApps). The emergence of Ethereum has completely changed the application scenarios of blockchain, making it no longer limited to payments, but becoming the infrastructure of the 'global computer.' In 2022, Ethereum completed 'The Merge,' transitioning from a proof-of-work (PoW) to a proof-of-stake (PoS) mechanism, significantly reducing energy consumption. $ETH, as the fuel of the platform (Gas fee) and the core asset of the ecosystem, is widely used in various fields such as DeFi, NFTs, and DAOs, and serves as an important engine for continuous innovation in the blockchain industry.
