Last week, core devs had to delay forking the Hoodi testnet to Glamsterdam to study a report by @chain_security which revealed some problems with how EIP-8037 interacts with a few contracts.
Over the weekend, ppl tried to get a better picture of the impact and by now it's quite well understood. So here's what you need to know:
What's been known is that contracts which hardcode forwarded gas are affected by repricings, e.g. making state writes (SSTORE) more expensive.
What's new is that some coding patterns rely on specific invariant which were broken with EIP-8037.
Gas already spent can come back mid-tx, so gasleft() can go up. This causes two problems:
(1) a before / after gas counter underflows and reverts
(2) a failed sub-call hands gas back, so a path that should've been unreachable runs, and the tx looks like it succeeded
Related but different: (3) measuring the gas usage of a call using GAS - before and after the call - might undercount because the state gas reservoir is not visible during execution (e.g. gas_left).
It's now about deciding how to proceed. Delaying hoodi bought time but won't resolve the issue. This week, we have to dig deep into contracts and make sure nothing is missed. Eventually, this might just need some coordination among the involved parties (dapps, core devs, auditors, people running nodes, etc.), or worst-case, spec changes.
If you're an app dev or auditor, check your contracts for issues with EIP-8037/EIP-8038, and report them.
Also, share this with your favorite app dev to spread awareness.
⚠️ It has just been decided to delay the Glamsterdam hard fork on the Hoodi testnet because of security impacts we identified in this blog post: chainsecurity.com/blog/glams…
We already found 13 real-world examples and are in responsible disclosure with the affected projects.
Please check your contracts as soon as possible, as the EF is determining how many contracts are impacted in which way.
Feel free to reach out to us with questions via [email protected].

After 3h and:
- Not a single payload missed
- No issues
My @go_ethereum impl fully self-migrated from the MPT to the Partitioned Binary Tree with
- 2TB disk
- 16GB of RAM!
Roots matching🎉
I'm very happy with the results and proud of this last months of hard work!
⏰ I* ⏰
It's happening!🚨🚨🚨
The next @ethereum's tree Partitioned Binary Tree is finally here! And we're migrating to it!
We are doing the first tree & DB migration in the Glamsterdam-devnet-8 with @go_ethereum @Nethermind @Besu_eth @ErigonEth
This is gonna be huge! Ready for I*🎉

Today the EF and OA announce zkAPI—a new means for private AI
Picture this: deposit ether into a vault, sign a zk proof, get a fixed amount of private inference. Advances like these help us move past middlemen's requirements that we link our data and identities.
Read more below
Quick updates on the Open Anonymity project (@OpenAnonProject)!
1. OA-chat is live! You can now signup: chat.openanonymity.ai
2. We collaborated with @ethereumfndn (@VitalikButerin, @DavideCrapis, @VittoStack, @curryrasul) to develop zkAPI, a new zero-knowledge protocol for accessing gated / paid APIs with unlinkability. It’s like a generalization of OA unlinkable inference that also abstracts payments away. Now also available on OA-chat!
I'm excited because more infrastructure should exist where privacy and sovereignty is foundational and people are in control.

I just read my first AI book.
Two months ago, I asked ChatGPT to imagine what the world might look like in 2050.
The answer was very interesting, so I asked it to write an entire fiction book set in that future.
It generated a ~100-page story about a world where AI gets so good at predicting human behavior that it can prevent tragedies before they happen.
The story explores a simple question: if AI could make the world safer by slowly taking away our ability to make mistakes, would we let it?
Among all the futuristic visions in movies and books, this one feels the most plausible to me.
The v1 of the book was a bit slow, so I asked ChatGPT to make a v2 more dynamic.
Here’s the book: drive.google.com/drive/u/0/f…
The chat expired, so ChatGPT made a new version. We might not be reading the same version.

We support EIP-8198 (Quick Slots) and @ethlabs_org’s push for faster Ethereum blocks!
Great read on the trading costs of slow blocks. Our own @josh_pwrk explains how arbitrageurs could take less price risk while waiting for their L1 spot trades to land, letting them step in on smaller price gaps and help keep spreads tight.
We're bringing Derive V3 to Ethereum L1, so we’d love to see this ship.

🎄🌲When Binary Tries?🌲🎄
You're witnessing @Nethermind @ErigonEth @go_ethereum and @Consensys 's Besu all handling a reorg while moving into Partitioned Binary Trie (eips.ethereum.org/EIPS/eip-8…)
You can't get it more solid than this!
Next step 👉 Mainnet migration tests

today EF Protocol published two posts. we hope you check them out!
for me, they mark the end of a transition that started back in april. when @kevaundray, @0xfredrik, and i stepped into the cluster coordinator roles, the job within the job was cluster-wide alignment: shaping a strategy born from our imperative (concentrate Protocol on what only Protocol can and will do), grounded in CROPS, and aimed at what Ethereum needs right now to endure for 1,000 years.
1️⃣ the first post makes that strategy public: a quantum-resistant ethereum L1 by december 2029, the multi-fork plan to get there, and what each of our five research arcs needs from the upcoming forks.
2️⃣ the second post is our first unified hardfork opinion: grades from every team in the cluster, argued down to one tier list covering every EIP proposed for hegotá, with the reasoning behind every grade.
read the priorities first. the tier list is those priorities applied.
lastly, Protocol is hosting a Reddit AMA on r/ethereum, sept 16 at 2pm UTC. hope to see you there. question form in the next post. 👇
The Protocol Cluster has published two new posts:
Hegotá EIP Opinion Post and Tier List evaluates and grades all 62 EIPs proposed for Hegotá, providing the cluster’s first unified tier list for a network upgrade
Current and Emerging Priorities covers commitments and research arcs, anchored on a quantum-resistant Ethereum L1 by Dec. 2029
Offered as one input to Hegotá scoping, roughly 60 researchers, engineers, and individual domain experts across all 9 teams in the Protocol Cluster contributed to the Hegotá tier list, providing 397 tier grades before discussing contested items live.
The plan, commitments, and shared set of cluster-wide priorities covered in the companion post provide the context behind the final tier grades.
The Protocol cluster will host a Reddit AMA on r/ethereum on September 16 at 2pm UTC to talk through these priorities, the Hegotá tier list, and anything else on your mind.

We've published the EF Protocol cluster's priorities and our first shared Hegotá EIP tier list, with input from ~60 researchers and engineers across all 9 Protocol teams.
We're aggressively targeting a quantum-resistant Ethereum L1 no later than December 2029. That has implications for what we propose including in Hegotá, and how much capacity we leave for the forks after it.
Keeping mainnet safe remains our first priority.
We'll be on r/ethereum for an AMA on September 16 at 2pm UTC. Please come ask us about the priorities, the tier list, or anything else you're curious about.
Tier and priorities posts and question form can be found below in this thread:

EIP-7610 is officially out of Glamsterdam. Thanks @JochemBrouwer96 for the PR! 🙌
eips.ethereum.org/EIPS/eip-7…
Next up: expect the Glamsterdam Meta EIP-7773 to move to Review 🔜
github.com/ethereum/EIPs/pul…
#Ethereum #Glamsterdam #EIP7773
The latest AllCoreDevs Consensus #185 updates are now live on @EIPsInsight.
Sepolia Glamsterdam is proposed for September 28, with Hoodi targeting October 26, pending further testing and confirmation.
EIP-7610 is officially cancelled from Glamsterdam, superseded by EIP-8253 targeting Hegota.
EIP-833 and EIP-8379 have moved forward for Hegota, while the reduced CL block retention proposal remains under discussion.
A non-finality DevNet is targeted for the week after next, with all clients expected to be on trunk/unstable branches first.
Hegota EIP tier rankings are also due from client teams by mid-September, with rough consensus targeted before DevCon.

1/ We're thrilled to welcome @AztecFND as the latest project to take the 1% Pledge 🎉
1% of the AZTEC token supply has been deposited into Protocol Guild's 4-year vesting contract to support 187 Ethereum core contributors across client teams, research, and coordination

Interop for Glamsterdam was a big success, and from what I can tell, it will bring major scaling improvements to Ethereum.
With BALs (EIP-7928), nodes can parallelize transaction execution, state root computation, and batch prefetch the state needed for a block.
With ePBS (EIP-7732), we get ~2-3x more time for execution.
Devs have been shipping non-stop this week, and I’m as tired as I am convinced this fork will be a huge unlock.

100 Ethereum contributors went to the edge of the earth and came back with a path to make it faster, stronger,
and might i say,
a bit more badass.
