Ethereum 2.0 Upgrade

Ethereum 2.0 is an upgrade to the Ethereum blockchain that aims to make it faster, more secure, and more scalable. It shifts from a proof-of-work system, which relies on energy-intensive mining, to proof-of-stake, where users lock up some of their Ether to help secure the network. This reduces energy use and increases transaction speeds. The upgrade also introduces new features like shard chains, which split the network into smaller parts to process transactions simultaneously. Overall, Ethereum 2.0 enhances the network’s efficiency, sustainability, and ability to support more applications and users.
