Ethereum Foundation: An Eth2 Progress Update

Danny Ryan𝕏

Ethereum will switch from Proof of Work (PoW) to Proof of Stake (PoS) likely already later this year in a much anticipated upgrade to Ethereum 2. The switch to PoS aims to make Ethereum both more secure and more sustainable by securing the network through Ether instead of mining. A second Eth2 update will address scaling through sharding at a later time.

Danny Ryan, Researcher with Ethereum Foundation, has been a major driving force behind the Eth2 project. He joined us for a progress update and we chatted about how the protocol will work in its steady state, what has launched so far, what happens in The Merge, and how PoS will affect centralization tendencies.
