What is Ethereum 2.0?

Ethereum 2.0, also known as the Merge or ETH 2.0, is a major upgrade to the Ethereum blockchain network. It aims to improve the scalability, security, and sustainability of the network by switching to a new consensus mechanism called Proof of Stake (PoS), which replaces the Proof of Work (PoW) used in Ethereum 1.0. This transition cuts Ethereum’s energy usage by 99% and makes the network more eco-friendly.
