ETH2 (consensus layer)
Ethereum 2 (ETH2) is an upgrade to the Ethereum (execution layer) that improves efficiency, speed, scalability, and overall security of the network.
The upgrade replaces the Proof-of-Work consensus mechanism with Proof-of-Stake.
The term 'ETH2' is being phased out in preparation for The Merge.​

Beacon chain

The ETH2 beacon chain is the Proof-of-Stake consensus layer. It is the coordination mechanism responsible for creating new blocks, validating them, and rewarding validators with ETH.
The beacon chain does not manage smart contracts or accounts. Writing or retrieving data is still managed by the Ethereum JSON-RPC API.

Get started

To get started with the Eth2 network, create an Infura account and an Eth2 project.
