$ETH Ethereum is the most influential blockchain platform after Bitcoin, with its core innovation being the support for smart contracts and decentralized applications (DApp). Through the Turing-complete Ethereum Virtual Machine (EVM), developers can create automated protocols, driving the explosion of fields such as DeFi, NFT, and DAO. The native token ETH is not only used to pay transaction fees (Gas fees) but also serves as a vehicle for ecological value. The Ethereum 2.0 upgrade completed in 2022 transitioned the consensus mechanism to PoS, reducing energy consumption by 99% and improving transaction efficiency. As the "world computer", Ethereum continues to lead Web3.0 innovation, reconstructing the trust paradigm in finance, gaming, and social fields.
