GAS2ETH opcode proposed for Glamsterdam
ERC-8004 gaining traction within the EF
New Foundry v1.4.0
New push for privacy at the EF
AllCoreDevs Update
One thing noted about the Holešky Fusaka fork during ACDT #56 was that Lighthouse nodes experienced a slightly higher reorg rate. This was under investigation by the Lighthouse devs and they were moving to make a fix for the issue.
Later, the BPO 1 fork went live for Holešky. This caused Nimbus low-core supernodes to become severely resource-constrained, making BPO 2 unviable on these setups. This occurred because the devnets were run using higher-spec’d machines, as opposed to Nimbus’s own testnet deployments (which up til now, didn’t need many cores). Something worth noting for node operators on low-specification hardware in case this isn’t resolved by the time mainnet goes live.
Some clients will also be dropping support for blob proofs in favor of cell proofs, so this should be noted particularly by rollup developers.
A number of non-headliner EIPs were proposed for Glamsterdam during ACDE #222:
EIP-8007 – gas repricings
EIP-8032 – SSTORE repricing to disincentivize state bloat
EIP-7907 and EIP-7903 (alternatives for changing the contract bytecode limit)
EIP-5920 – PAY opcode
EIP-7791 – GAS2ETH opcode
GAS2ETH is particularly interesting as it would allow contract developers to include a way of paying addresses ETH based on contract usage.
A reminder was given that there will only be one week to continue proposing the non-headliner Glamsterdam EIPs once the Fusaka mainnet date is determined.
Ethereum News & Discussion
Vitalik posted an article arguing that memory access is O(n^(1/3)).
It appears ERC-8004 is gaining traction within the EF. Consider reaching out to ai@ethereum.org if you’re building autonomous commerce.
If you want to learn more about this ERC, check out this post with a number of links to videos about it.
The EF posted an article discussing the formation of the new Privacy cluster, spanning research, protocol, applications, and institutional adoption.
The EF also posted about their collaboration with Keyring Network in piloting zkVerified vaults whose first two months of protocol fees fund the defense of Tornado cash developers Roman Storm and Alexey Pertsev, proposing a scalable on-chain blueprint for market-aligned impact funding.
ncsgy wrote a thread about Kohaku, a privacy-focused wallet SDK.
Public reference materials have been published for the Institutional Privacy Task Force at the EF.
Research Update
Removing Pairing, Bulletproofs, or ZKP from Range Proof of Pedersen Commitment by leohio
A lightweight EVM-verifiable range proof for Pedersen commitments is proposed that frontloads a one-time zkSNARK-backed Merkle tree setup of aXG leaves and a public anchor U=aB, then verifies transactions without pairings or Bulletproofs using only Chaum–Pedersen DLEQ, Schnorr/ECDSA checks, and simple EC operations (6 ECMUL, 3 ECADD), while mitigating malleability via U=aB and reducing Merkle size through randomized point sets scaled on-chain.
The Economics of Instant: An Exploration of Real Time Ethereum by Antero Eloranta
Reducing Ethereum’s 12-second block time materially lowers adverse selection in AMMs, enabling lower optimal fees that undercut centralized exchange costs, increasing liquidity provider revenue through more frequent but less toxic arbitrage and higher noise trading volume, with empirical Uniswap v3–Binance analysis suggesting major-asset pools optimally cluster around low single-digit to low-teens basis points and can realize substantial revenue gains—up to an order of magnitude in thin-liquidity cases—while improving trader execution certainty and price freshness.
