Eth News and Links
Dencun (Cancun + Deneb) upgrade
- Latest all core devs – execution (ACDE) call video. Recap by Tim Beiko. Notes from Tim Beiko and Christine Kim:
- Devnet 9 testing continues, MEV-Boost testing started (need to test with blobs)
- Devnet 10 ideally launches next week, once KZG setup in CL specs/clients and devnet 9 testing complete
- EVM Object Format (EOF) status update
- Discussions on priorities/timeline for EOF & Verkle, whether to ever include EOF and L1/L2 EVM divergence
Centralization watch: threatening the value of your ETH
- 🚨 Lido at 31.89% has reduced again but still far too close to 33.3% threshold
- Arbitrum delegates voted against incentives for Lido
- Client diversity (via clientdiversity.org):
- Execution layer: Geth ~84% supermajority, could possibly cause a chain split
- Consensus layer: Prysm at 45%, any client bug over 33.3% could mean loss of finality
- Blockprint (CL client diversity analysis) updated to include accuracy data
- Geographic diversity needed for stakers & nodes, particularly outside of US/Can/EU
Layer 1
- Péter Szilágyi (Geth): proposal for eth/69 to improve transaction propagation, no hard fork required
- Proposal for time restricted transaction execution, add a minStartTime field to transactions
- Verkle Tree cryptography implemented in Zig
For Stakers
- Beacon chain churn limit increased to 13 per epoch (Dencun EIP7514 reduces to 8 for deposits)
- ~9k solo stakers: estimate based on deposit addresses interacting with smart contracts
Client releases
- Consensus layer:
- Teku v23.10.0: attestation duty calculation performance improvements
- Execution layer:
- Besu v23.10.0: Layered transaction pool now default
- Erigon v2.52.0: fixes
- Otterscan v2.1.0 alpha: adds indexer for withdrawals per address
- Geth v1.13.3: updates Pebble to fix occasional IO/CPU runaway
Research
- Vitalik’s proposed staking design changes to give delegators power to choose nodes & participate in consensus, improving decentralization & reducing consensus overhead
- Minimum viable issuance (only issue ETH that is strictly needed for security): benefits & drawbacks
- PEPC-Boost: out of protocol relay design which auctions top-of-block & rest-of-block separately
- Commitment-Satisfaction Committees: leverage attesters to enforce commitments for PEPC
- Proposal for optional validator identification metadata
Layer 2
- L2BEAT Build Your Own Rollup: simplified sovereign rollup for education purposes
EIPs/Standards
- EIPs
- ERCs (application layer):
Optimism’s RetroPGF Round 3 applications are open
Applications for Optimism’s RetroPGF Round 3 are open!
In this round 30 million OP will be allocated to the builders, artists, creators, and educators who have demonstrated their impact in building the Optimism Collective.
