## Summary

This is a weekly roundup of Ethereum news for April 20, 2024, covering protocol development, security, regulation and events. On the protocol side, the Pectra upgrade's Electra EIPs were discussed on the all core devs consensus call, with EIP7251 (max effective balance) and EIP7549 (committee index outside attestation) listed among those included. The execution call added EIP3074 and EIP2935 to Pectra, with Pectra described as a small fork targeting late 2024. Security items include a $44M Hedgey Finance exploit on Arbitrum and mainnet and a $2M Grand Base exploit on Base, and Uniswap Labs is reported to have received a Wells notice from the SEC.

## Article

Pectra (Prague + Electra) upgrade (meta EIP7600)

Latest all core devs – consensus (ACDC) call video. Notes from Christine Kim:

Electra included EIPs:

EIP7251 maxEB: changing to execution layer triggered consolidations after pectra-devnet-0 and proposal to apply deposit to state when epoch finalized

EIP7549 move committee index outside attestation: discussion on handling Deneb attestations at fork boundary and proposal to replace committee bits with indices

Electra proposed additions:

EIP7685 general purpose execution layer requests: consolidate request types, decide Monday on including

EIP7691 blob throughput increase: short term scaling before PeerDAS, exact values to be based on testing, alternative to EIP7659 stepped increase

Electra candidates for inclusion:

EIP7547 inclusion lists: issues with EIP3074 can’t be resolved for Electra

Node-id mapping to attestation subnets: clarification for mainnet & PeerDAS

consensus-specs v1.5.0-alpha.0: initial Electra spec for pectra-devnet-0

Latest all core devs – execution (ACDE) call video. Notes from Tim Beiko & Christine Kim:

Pectra upgrade (small fork targeting late 2024)

EIPs added to Pectra & will be part of pectra-devnet-0:

EIP3074 AUTH/AUTHCALL opcodes

EIP2935 save historical block hashes in state

EIPs considered for inclusion:

EOF: need to assess cross client testing complexity & any potential issues with Verkle

EIP7623 increase call data cost: need to consider best mechanism to cap block size

EIP7547 IL (inclusion lists): some opposition to including

Osaka upgrade

EIPs considered for inclusion:

EIP7667 raise gas costs of hash functions

EIP3074 AUTH/AUTHCALL opcodes

Lightclient: addressing EIP3074 concerns

EIP7251 maxEB (increase max effective balance)

Breakout call video & notes: staking providers prefer execution layer triggered consolidations (consolidations not in pectra-devnet-0) and don’t need custom ceilings

Osaka + F starname upgrade (meta EIP7607)

Verkle:

Implementers call video & notes

Centralization watch: threatening the value of your ETH

🚨 Lido at 28.7% still too close to 33.3% threshold

Client diversity (via clientdiversity.org):

Execution layer: Geth ~63% majority

Consensus layer: Prysm 38%

Any client bug over 33.3% could mean loss of finality

Better geographic diversity is optimal, particularly outside of North America & Europe
