EVM Gazette – October 27, 2025
Issue #8
Highlights
Holešky shutting down on October 31 – migrate if you haven’t already
Gas repricing discussions underway; gas hardcoders beware
A new smart contract library from the Perfect Abstractions team
The Solidity team published an article on the road ahead for Core Solidity
AllCoreDevs Update
Important reminder: those who want to submit non-headliner EIPs for inclusion in Glamsterdam should at the very least open a PR for them in the EIPs repo by October 30 and make efforts to signal publicly about the proposal (e.g. by commenting in the issue for the upcoming ACDC). With this timing, the team is aiming to get client teams to submit their thoughts on each EIP by November 6, giving perhaps enough time to finalize the Glamsterdam scope by the end of November.
Another important note: Holešky is winding down operations on October 31. Everyone using Holešky should migrate to either Sepolia or Hoodi by that time.
An update for Mainnet: while it seems the December 3 date will be going as planned for the initial Fusaka fork, the first BPO fork will be moving to December 9 from 17, while BPO2 will be Jan 7.
Besu, reth, geth, and Nethermind have been able to get a BAL devnet up and running. So far Besu is passing all tests.
A potentially interesting discussion for smart contract developers took place on this past ACDE (#223): Maria Silva brought up an issue related to gas repricing, noting that compute opcodes are being underpriced due to rounding errors. She proposed solutions two potential solutions to this. Developers should be aware that fixing this issue may result in certain contracts to break due to hardcoded assumptions concerning gas.
ACDE #223 also saw a presentation from CPerezz regarding EIP-8058.
It was also noted during this call that EIP-7667 and EIP-6873 are being removed from the PFI list for Glamsterdam.

Research Update
Zkzkevm: private evm by barryWhiteHat
A proposal to enable privacy-preserving EVM contracts by adding two opcodes—pload and pstore—that operate over a Private Storage Tree and Private Nullifier Tree to support private per-user state (with membership and non-nullification proofs) while acknowledging the impossibility of private global state without IO, outlining compilation changes, call-chain sanitization, and tradeoffs for practical private rollups and cartel-style contracts.
Nonce Bitmap - Enabling Parallel Transaction Submission for a Parallel Blockchain by 14mp4rd
A bitmap-augmented nonce scheme that encodes a 256-slot parallel index in the high 8 bits of Ethereum’s 64-bit nonce enables concurrent transaction submission with minimal state overhead (32 bytes per account), preserves replay protection and backward compatibility for legacy wallets, and offers a pragmatic alternative to random nonces, time-bounded schemes, and 2D nonces for low-latency, high-throughput chains.
Variants of Mempool Tickets by Julian
Outlines vertically sharded mempool design for Ethereum and evaluates four ticketing variants—Wholesale, Leases (stake/LIFO), Simple, and Loyalty—to mitigate sampling-based DoS by pre-allocating blob propagation rights, arguing for posted-price, potentially free tickets prioritized by fee, emphasizing reduced bandwidth, operational flexibility, and upgradability via contracts rather than hard forks, with trade-offs in censorship risk, liquidity demands, and UX under anticipated PeerDAS-driven throughput growth.
Mediabs2022 posted three articles, collectively presenting a unified framework of Ethereum proof‑of‑stake adversarial strategies—starting with one‑epoch inactivation primitives, composing them into Rifle attacks via unidirectional attestations and delayed release, and extending to Unrealized manipulation and Byzantine takeover that use RANDAO grinding to secure favorable proposer slots—aimed at cyclic liveness degradation, checkpoint justification on attacker branches, and systematic reorgs that maximize honest validators’ incentive loss.
