Week in Ethereum News October 7, 2023

Dencun (Cancun + Deneb) upgrade

Latest all core devs – consensus (ACDC) call video. Notes from Christine Kim:
- Devnet-9: testing finding issues, MEV-Boost testing started (20% of the network)
- Devnet-10: launch once no issues on devnet-9, short lived, to include KZG ceremony
- Goerli testnet upgrade timing: still too early to set a date
Dencun interop testing call video

Centralization watch: threatening the value of your ETH

🚨 Lido at 32.13% has slightly reduced but still far too close to 33.3% threshold
Client diversity (via clientdiversity.org):
- Execution layer: Geth ~80% supermajority, could possibly cause a chain split
- Consensus layer: Prysm at 45%, any client bug over 33.3% could mean loss of finality
Geographic diversity needed for stakers & nodes, particularly outside of US/Can/EU

Layer 1

For Stakers

Client releases

Layer 2

EIPs/Standards

EIPs
- EIP7530: EVM profiles for zk rollups
ERCs (application layer):
- ERC7527: Token bound function oracle AMM contract
- ERC7528: ETH (native asset) address convention (0xe)
- ERC7529: Contract discovery and eTLD+1 association
- ERC7531: Staked ERC721 ownership recognition

Lido governance is not fit for purpose. Don’t miss this episode with Ben Edgington. (Watch on YouTube)

Ben also talks about his Upgrading Ethereum book and Ethereum governance.
