Ethereum 2.0

Ethereum 2.0, also known as Eth2 or Serenity, is an upgrade to the Ethereum blockchain, designed to enhance its scalability, security, and sustainability. It transitions from a proof-of-work system, which relies on energy-intensive mining, to proof-of-stake, where validators are chosen based on the amount of cryptocurrency they hold and are willing to 'stake' as collateral. This change reduces energy consumption and allows for faster transaction processing. Overall, Ethereum 2.0 aims to support more users and applications while maintaining the decentralized nature that makes blockchain technology appealing.
