Abstract: Ethereum 2.0 is an update to the current Ethereum blockchain that aims to address the scalability, security, and sustainability issues with the first network. The upgrade will be carried out in phases and come with various important improvements. It's crucial to remember that Ethereum 2.0 has been developed over a long period of time and gradually, thus the features and specifications may have changed since the last release. Because ETH 2.0 is a completely other project, the moniker Ethereum may be a little confusing. EHT2 will speed up transactions without compromising security while also enhancing the blockchain's programmability and scalability.

Keywords: Ethereum 2.O, PoW, PoS, Sharding
