Dencun (Cancun + Deneb) upgrade (meta EIP7569)
- Latest all core devs – execution (ACDE) call video. Recap by lightclient. Notes from lightclient & Christine Kim:
- Testnet upgrade dates confirmed (assumes no issues): Goerli Jan 17, Sepolia Jan 30 & Holešky Feb 7
- Pectra (Prague + Electra): discussed small feature upgrade first vs focusing on Verkle (~18 months) and reviewed proposed EIPs
- Precompile address ranges: proposed EIP7587 (reserves 0x100-0x1ff for RIPs)
Centralization watch: threatening the value of your ETH
- Lido at 31.71% is far too close to 33.3% threshold
- Client diversity (via clientdiversity.org):
- Execution layer: Geth ~84% supermajority, could possibly cause a chain split, estimated to cost billions of dollars
- Consensus layer: Prysm 41%, any client bug over 33.3% could mean loss of finality
- Better geographic diversity is optimal, particularly outside of North America & Europe
Layer 1
- libp2p TCP vs QUIC: TCP ~2x speed of QUIC
Client releases
- Consensus layer:
- Nimbus v24.1.0: Goerli testnet Dencun upgrade and adds v3 blocks/{slot} Beacon API end-point
- Execution layer:
- Erigon v2.56.0: Goerli testnet Dencun upgrade
- Nethermind v1.25.0-rc: Goerli testnet Dencun upgrade and OP Stack Canyon support
Research
- Proposer selection with EIP7251 (increase max effective balance): probability remains the same for consolidated validators
MEV

- Timing.pics (dashboard of timing games): missed slots & bids selected by entity
