New Week in Ethereum 2025-11-07

Week in Ethereum News

The Ethereum team officially confirmed the “Fusaka” upgrade for mainnet deployment on December 3, 2025, introducing major infrastructure improvements—including the peer-data-availability sampling (PeerDAS) mechanism and increased block capacity—to boost Layer-2 performance and node efficiency

All Core Devs - Execution (ACDE) #224, November 6, 2025:
- Fusaka upgrade: Confirmed mainnet release dates with BPO1 on December 9 and BPO2 on January 7, 2026. Nethermind team is investigating a bug related to re-orgs.
- Glamsterdam upgrade: Conducted a comprehensive review of 40 EIPs, discussing client positions and potential bundling approaches. Client teams shared their perspectives on various EIPs, with Geth, Erigon, and Nimbus presenting their stances.
- Repricing efforts: Discussed various repricing options for the Glamsterdam upgrade, with proposals from Caspar, Ansgar Dietrichs, Maria Silva, and Marius van der Wijden.
- STEEL: The team announced the completion of the WELD process, unifying execution spec test code into execution specs.

The Ethereum Foundation published the official Fusaka mainnet announcement, confirming the upgrade will activate at slot 13,164,544 (December 3, 2025, 21:49:11 UTC).
Fusaka introduces Blob Parameter Only (BPO) forks to safely scale blob throughput after PeerDAS activation. BPO1 will increase the per-block blob target to 10 and maximum to 15 on December 9, while BPO2 will further increase the target to 14 and maximum to 21 on January 7, 2026.
The upgrade includes several key EIPs, including EIP-7594: PeerDAS, EIP-7883: ModExp Gas Cost Increase, and EIP-7951: Precompile for secp256r1 Curve Support.

Client teams have published their perspectives on EIPs proposed for inclusion in the Glamsterdam upgrade, including Erigon, Geth, Nethermind, Nimbus/Pureth, and Reth.
The STEEL team published "The Weld is Complete: Welcome to Unified Specs and Tests", announcing the completion of welding execution spec test code into execution specs.
A discussion has begun on finding a portmanteau for the Heka + Bogotá upgrade that will follow Glamsterdam.

Gas limit signalling snapshot: Community dashboard shows last update Nov 6 with a 24-hour avg gas limit ≈ 45,002,012, i.e., near the current cap, with ongoing validator signalling tracked there. Useful context for bandwidth/blob-count discussions.
MEV infrastructure reality check: Live relay/builder stats this week show continuing concentration among a few builders (e.g., Titan, BuilderNet, Quasar), underscoring why inclusion-list and PBS discussions remain active.

The Future of State, Part 1: OOPSIE: A proposal for a new type of Snap Sync-based wallet/lightclient that could improve user experience and reduce resource requirements.
The Future of State, Part 2: Beyond The Myth of Partial Statefulness & The Reality Of ZKEVMs: An exploration of state management approaches for Ethereum's future, examining the limitations of partial statefulness and the potential of ZKEVMs.
Block building & MEV: Proposes a “MEV Lock” — a trivial, enshrined-PBS-like design that randomly selects 0x03 builder-validators by stake, removes proposer↔builder latency, and shifts MEV economics (no bid payments; capital cost on builder stake). Requires inclusion lists to counter centralization.

Starknet rolled out the open-source S-two prover on mainnet, claiming faster proofs and lower costs—positioning the network for privacy features and broader decentralization

The Balancer protocol suffered a large exploit, with estimates ranging up to US $128 million drained across multiple chains, including Ethereum mainnet, due to vulnerabilities in its Vault architecture

Devconnect set to open in Buenos Aires in two weeks, featuring the first-ever Ethereum World's Fair at La Rural, showcasing real-world applications of Ethereum technology.
Ecosystem Support Program unveiled a new grants program designed to be more targeted, impactful, and sustainable, evolving alongside Ethereum's growth after temporarily pausing open grant applications.

🚨 Lido at 23.57%, still too close to the 33.3% threshold.
Client diversity (via clientdiversity.org):
- Execution layer: Geth ~41% & Nethermind ~38%
- Consensus layer: Lighthouse 42.71% & Prysm 30.91%
- Any client bug over 33.3% could mean loss of finality.
Better geographic diversity is optimal, particularly outside of North America & Europe.

Execution layer:
- Geth v1.16.7: Critical release that enables the Fusaka hardfork on Ethereum mainnet scheduled for December 3, 2025. Includes a fix for a cryptographic vulnerability in c-kzg-4844 library, adds eth_sendRawTransactionSync method, and improves networking with metrics for tracking slow peers.
Consensus layer:
- Lighthouse v8.0.0: Major release with Fusaka mainnet support. Includes important changes for PeerDAS, memory optimizations, and support for BPO forks. This will be the last Lighthouse release supporting Windows.

EIPs (Core, Networking, Interface):
- EIP-7976 (Core) — Increase calldata floor cost: added an empirical impact analysis report.
- EIP-7916 (Core) — SSZ ProgressiveList: refined the Motivation section wording to better explain efficiency and stability goals
- EIP-6404 (Core) — SSZ transactions: moved the “union layer” into the payload; structural spec cleanup.
ERCs (Application Layer):
- ERC-7730 — Structured Data Clear Signing Format: removed embedded ABI from schema & examples; made “display formats” the single source of contract typing; tightened schema rules and examples.
- ERC-7908 — HD wallet in Treasury Management: status moved to Last Call.
- ERC-7857 — AI Agents NFT with Private Metadata: status moved to Final.

Fees (via ultrasound.money):
- Gas: 0.0 to 97.7 gwei, 1.1 gwei average; zero net issuance at 16.3 gwei
- 17.35 ETH net issuance this week
ETHUSD: $3,162 – $3,911, currently $3,438, all time high $4,946
ETHBTC: currently 0.033 (Flippening at ~0.165)

Ethereum stakeholders launch coordinated lobbying group: Major DeFi protocols including Aave Labs, Aragon, Curve, Lido Labs Foundation, Spark Foundation, The Graph Foundation, and the Uniswap Foundation have formed the Ethereum Protocol Advocacy Alliance (EPAA) to counter the "outsized influence" of centralized crypto entities in policymaking.

Ethereum erases 2025 gains but shows signs of recovery: ETH price dropped to around $3,000 but analysts suggest this may be a "massive bear trap" with accumulation signals indicating potential recovery.
