The future of Ethereum is a topic of much attention and discussion. It has both great potential and challenges. Here are some key aspects: Potential: Ethereum 2.0 (Eth2): This is the most important upgrade of Ethereum, designed to address scalability, security, and sustainability issues. It introduces a proof of stake (PoS) consensus mechanism, replacing the original proof of work (Proof-of-Work (PoW). PoS can significantly reduce energy consumption and improve transaction processing speed. The introduction of sharding technology will also further improve scalability, allowing the Ethereum network to process more transactions in parallel. Decentralized Finance (DeFi): Ethereum is the main platform for DeFi applications. DeFi aims to build an open, license-free and transparent financial system, including lending, trading, stablecoins, derivatives, etc. With the continuous development of DeFi, it has the potential to change the traditional financial landscape.
