Beacon Chain

The proof-of-stake consensus layer of Ethereum, coordinating validators since December 2020.

What is Beacon Chain?

The Beacon Chain is Ethereum’s proof-of-stake (PoS) blockchain, launched on December 1, 2020, to manage the PoS consensus mechanism. It operates as the coordination layer for validators who stake ETH to secure the network, propose blocks, and attest to their validity.

Fully integrated with Ethereum’s execution layer during The Merge in 2022, the Beacon Chain replaced proof-of-work mining, enabling faster and more energy-efficient transaction processing. It is critical for Ethereum’s security and scalability, supporting validator duties and finality.
