Dankrad Feist: Ethereum Foundation – An Eth2 Progress Update #2

Ethereum 2.0 is an upgrade to the Ethereum network that aims to improve the network's security and scalability. Recently, we chatted to Danny Ryan about the Merge and switch to Proof of Stake. As a follow up to that episode, we were joined by Dankrad Feist, who heads the sharding and statelessness research at the Ethereum Foundation. We dove deep into the technical infrastructure of how Eth2 addresses scaling through sharding, the pros and cons of data shards vs. execution shards, and how this links up with ZK-rollups. We also talked about the Ethereum state and how the state can be altered for protocol improvements.
