• Fusaka upgrade (targeting 2025):

  • Mainnet upgrade potentially in December if testing goes well, timeline based on upgrade process (30 days between client releases & first testnet and 30 days between last testnet & mainnet); Checking with L2s & infrastructure teams on timing requirements

  • Fusaka-devnet-3: syncing issues during non-finality testing, retest once fixed, consensus layer client teams need to merge to trunk branches, can then launch Fusaka-devnet-5

• Holešky testnet will be deprecated after upgrading to Fusaka

• Gas limit blockers for increasing to 60M (up from 45M)

• Glamsterdam upgrade (targeting June 2026):

  • Headliners: EIP7732 ePBS (consensus layer) & EIP7928 Block-level Access Lists (execution layer)

  • Non-headliner EIPs are being proposed for inclusion:

    • Deadline for proposals is Fusaka mainnet releases

    • Client teams can specify EIPs they want more info on (e.g. Besu)

    • Discussed: Meta EIP8007 gas repricings, EIP2926 chunk-based code Merkleization (presentation), EIP7843

• Ethereum Foundation:

  • EF Protocol AMA on Reddit

  • Protocol update #2 (blob scaling): Blob Parameter Only (BPO) upgrades after Fusaka can increase blobs up to 8x, future scaling via PeerDAS v2, blobpool scaling & FullDAS

• Glamsterdam upgrade:

  • [Headliner] EIP7928 Block-level Access Lists breakout #1: client teams started implementing

  • [Considered for Inclusion] EIP7805 FOCIL breakout #18: rebasing onto Fulu & adding metrics

• Anders Elowsson: generalized blob base fee update fraction calculation

• Ethproofs call #4: $1M proximity prize to prove/disprove Reed-Solomon proximity gaps conjectures & proof status monitoring

• PQ Interop

• beaconcha.in validator dashboard v2: no longer in beta

• Obol Charon v1.6.0 (distributed validator): QUIC support (alpha)

• Client diversity:

  • Consensus layer: Lighthouse 42.7%

  • Execution layer: Geth ~41%, Nethermind ~38% (estimated from self reports)

• Staking marketshare: Lido 24.3%

• Client releases:

  • Execution layer:

    • Besu 25.8.0: faster sync using less memory & CPU and faster block creation

• L2Beat native rollups book: includes EXECUTE precompile draft spec

• Synchronous composability protocol (SCOPE): push-based synchronous crosschain function calls, proof of concept
