The Beacon Chain is an essential component of Ethereum 2.0, a major upgrade to the Ethereum blockchain. It serves as the backbone of the new Proof of Stake (PoS) consensus mechanism, providing finality and organizing validators into committees. The Beacon Chain coordinates the consensus protocol, manages validators, and stores important network information. It plays a crucial role in ensuring the security, scalability, and sustainability of the Ethereum network as it transitions from Proof of Work (PoW) to Proof of Stake. https://sites.google.com/beaconchas.com/beaconchainn/home
