Dencun (Cancun + Deneb) upgrade (meta EIP7569)
- Latest all core devs – execution (ACDE) call video. Notes from Tim Beiko and Christine Kim:
- Dencun upgrade client releases expected next week, followed by a mainnet shadow fork
- Retroactive EIP proposals: EIP7610 (revert contract creation for non-empty storage) need to discuss Verkle interaction and EIP7523 (deprecate empty accounts) need to verify no empty accounts
- Pectra upgrade (small fork targeting late 2024)
- Discussions on potential EIPs:
- EIP5806 (delegate transaction), alternative to EIP3074
- EIP7557 (block-level warming)
- EIP2935 (historical block hashes in state) updated for Verkle
- EIP5920 (PAY opcode)
- EIP7609 (decrease TLOAD/TSTORE base cost)
- Agreed to include EIP2537 (BLS precompile)
- Discussions on potential EIPs:
- consensus-specs v1.4.0-beta.7: schedule mainnet Dencun upgrade
Osaka upgrade (meta EIP7607)
- Verkle implementers call video & notes: updates from client teams & testing team, EIP2935 updated, new EIP7612 and deprecating serialize commitment
Centralization watch: threatening the value of your ETH
- 🚨 Lido at 31.69% is far too close to 33.3% threshold
- Client diversity (via clientdiversity.org):
- Execution layer: Geth 69% supermajority, could cause a chain split
- Lido’s use of supermajority client continues to put Ethereum at risk
- Supermajority dashboard: simulate Lido operators changing to minority clients
- Consensus layer: Prysm 38%, any client bug over 33.3% could mean loss of finality
- Execution layer: Geth 69% supermajority, could cause a chain split
- Better geographic diversity is optimal, particularly outside of North America & Europe
Layer 1
- Local shadowforks with single line command using Kurtosis over Docker or Kubernetes
- Erb (blob archive files) design decisions, store blobs alongside Era archive files
- Inclusion list breakout call video & notes from Terence
ePBS (enshrined Proposer-Builder Separation)
- ePBS breakout call video & notes from Terence
- Terence: minimal ePBS Beacon chain changes
- Francesco: options to harden PBS without full enshrinement
MEV
- MMASim: MEV-Boost auction simulation framework
- predictive MEV-burn: proposal to incentivize builders to predict a blocks value
- Leaderless auctions: decentralized MEV-resistant auction with no auctioneer
Research
- Barnabe: rainbow staking, framework for protocol service providers (professional operators & solo stakers) to participate in spectrum of heavy (slashable) & light (non/partially slashable) services
For stakers
- Blobs use max 103 GiB (average 50 GiB) plus the blob pool
Client releases
- Consensus layer:
- Teku v24.2.0: mainnet Dencun upgrade
- Execution layer:
- Besu v24.1.2: mainnet Dencun upgrade
- Nethermind v1.25.4: mainnet Dencun upgrade
- Reth v0.1.0-alpha.18: mainnet Dencun upgrade and trie performance improvements
Support the Roman Storm & Alex Pertsev legal defense fund
The Biden administration is attempting to criminalize open source software development as part of its war on crypto.
The fundraiser ends THIS WEEK. Donate to defend our innocent Ethereum heroes.
Layer 2
- Ed Felten: blobs explainer for L2 users, transactions will be cheaper (unknown by how much)
- RollCall (L2 standards) call video and notes: L2s generally plan to use blobs soon after Dencun upgrade, recap of breakout calls and proposed RIP7614 (expose call stack to contracts)
- Based rollups:
- Sequencing & pre-confirmations call video
- Justin Drake answers shared sequencing concerns
- Starknet airdrop claimable from Feb 20, includes pre-Merge stakers, Protocol Guild, EIP/ERC authors and contributors to Ethereum repos, US not eligible
- ApeChain to use Arbitrum
