Ethereum 2
Ethereum 2, also known as Eth2 or the Ethereum 2.0 upgrade, is a major evolution of the Ethereum blockchain that transitions it from a proof-of-work (PoW) consensus mechanism to a proof-of-stake (PoS) system. This upgrade aims to significantly improve scalability, security, and energy efficiency by introducing sharding and a new staking-based validator network. It represents a phased overhaul to address limitations in transaction throughput and environmental impact of the original Ethereum network.
Developers should learn Ethereum 2 to build and deploy decentralized applications (dApps) that require higher transaction speeds, lower fees, and enhanced security, such as in DeFi, NFTs, and enterprise blockchain solutions. It's essential for those working on Ethereum-based projects to adapt to the new PoS model, as it affects smart contract deployment, validator operations, and overall network interaction, ensuring future-proof development in the evolving Web3 ecosystem.
