Highlights
The Fusaka testnet fork schedule is now officially included in the Meta-EIP.
Confirmed 60 million gas limit for Fusaka
New OpenZeppelin contracts release candidate.
Erigon Nitro alpha release for Arbitrum Sepolia
AllCoreDevs Update
There are two big news items coming from AllCoreDevs this week:
The Fusaka testnet fork schedule (together with BPOs) has been published to the Fusaka Meta EIP (EIP-7607). The mainnet fork dates are yet to be officially included.
On the mainnet Fusaka fork, all clients will be defaulting to a 60M gas limit pursuant to EIP-7935 (which was recently modified to concretize the gas limit).
Some other things of note:
Tim Beiko proposed halting further proposals for Glamsterdam until enough time has passed to move more EIPs from CFI to SFI.
Hadrien Croubois of OpenZepplin proposed EIP-7819 (SETDELEGATE) for Glamsterdam.
wolovim opened a PR to EIP-7723 (“Network Upgrade Inclusion Stages”) that introduces the concept of a champion for proposed EIPs (nixorokish had the interesting idea that this should be the one who opens the PR to include the EIP as proposed in the hard fork meta EIP).
Ansgar Dietrichs will be taking over for Tim Beiko for the time being on AllCoreDevs calls.
Based on the recent addition of the fork timeline to EIP-7607, it looks like Mainnet fork could go live as soon as late November (30 days after Hoodi) but it’s quite probable the team will stick to early December in line with the timeline discussed the week before, especially considering late November might not give much time to recover from the end of Devconnect.
Ethereum News & Discussion
The Ethereum Foundation published a blog post on Fusaka testnet forks.
0xPrincess of nuconstruct announced the TOOL testnet launch on Hoodi. Read about how TOOL works here. (Could we see the demise of PBS?)
polymutex is now working on Walletbeat full-time. If you haven’t heard of it, Walletbeat is like the L2BEAT of wallets. Check it out for info on things like which wallets best support privacy.
They’re also looking for contributors.
Vitalik defends Base’s position as an L2 and as an “extension of Ethereum”.
Ben Adams of Nethermind wrote an article on their work preparing their L1 client for ZK.
Vitalik posted a new article, where he argues that our digitized “real life” demands guinely open, end-user-verifiable software, hardware, and biotech to secure trust, prevent centralized leverage, and enable resilient civic, health, and financial systems, starting with a fully open, verification-friendly stack for high-security, low-performance use cases.
hildobby of Dragonfly posted an informative thread on blob usage at present.
Jihoon Song posted a summary of FOCIL breakout call #20.
Frangio started a discussion on Ethereum Magicians about EVM Immediates. It focuses on how opcodes that include operands within them (like PUSH* opcodes, rather than taking their operands from the stack) without breaking backwards compatibility.
In case you missed it, donnoh.eth of L2BEAT has been working on a book on native rollups.
gcolvin followed up on his feedback to EIP-7923.
Check out the AI-powered New Week in Ethereum newsletter. They published an introductory post on Ethereum Magicians.
The Walnut team published a call for feedback on their new Solidity debugger, SolDB.
Research Update
BALs for Proposer Commitments by jvranek
“This post aims to motivate using BALs for preconfs, highlights proposed spec changes to make them proof-friendly, and outlines the complexity trade-offs under discussion in Discord.”
Trustless Consensus Manipulation Through Bribing Contracts by 0xsooki
Transparent, on-chain bribery contracts leveraging cheap BLS verification enable three practical attacks—PayToAttest (safety-violating ex‑post reorgs with bribes as low as 0.09 ETH), PayToExit (liveness erosion via optimal bribes such as 9.23 ETH to raise stake from 23% to 33%), and PayToBias (fairness manipulation of the RANDAO beacon)—demonstrating that Ethereum’s short‑term economic security hinges on marginally outpaying protocol rewards, and motivating countermeasures including single-slot finality, whistleblowing incentives, and unbiasable randomness.
Deep Funding: A Prediction Market For Open Source Dependencies by Elizabeth Yeung, Clément Lesaege, Devansh Mehta.
Deep Funding proposes an automated, jury‑resolvable prediction market over a weighted dependency graph of Ethereum OSS repositories, where bots, models, and traders stake on edge weights to dynamically allocate funding based on predicted juror assessments—mitigating sybil incentives, enabling specialization, and scaling credible neutrality through periodic spot‑checks, bonded inclusion, and market‑determined liquidity rather than exogenous prizes.
