# Ethereum Beacon

The Ethereum beacon chain is a core component of the Ethereum 2.0 upgrade. It is a new proof-of-stake (PoS) blockchain that will eventually replace the current proof-of-work (PoW) Ethereum blockchain. The beacon chain is responsible for managing the overall operation of the Ethereum 2.0 network, including managing the validator set and the consensus mechanism.
