$ETH plays a pivotal role in the development of decentralized internet Web3. With the network transitioning to a proof-of-stake (PoS) mechanism through the "Ethereum 2.0" upgrade, it has become more energy-efficient, increasing its appeal to investors and developers. The future of Ethereum includes support for smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), and decentralized applications (dApps). It also aims to improve scalability through solutions like "sharding" and "Layer 2". Challenges include fierce competition from other blockchains and government regulation. However, Ethereum remains the cornerstone of the future digital economy, with broad aspirations for achieving true and comprehensive decentralization in data management.
