Last week, Ethereum core contributors gathered in Svalbard for the Soldøgn interop: a week long event focused on hardening Glamsterdam implementations to scale Ethereum securely ☀️
Read the full recap, including their candidate post-fork gas limit, below:

Fusaka HF activated and finalized on Gnosis, GG
Just a ~6% participation drop, so update your nodes if you haven't!
Apr 14
The Fusaka hardfork has been activated on the Gnosis Chain mainnet! 🦓
A massive shout-out to our validators and node operators your quick updates and dedication are what keep the network resilient and decentralized.
Next ⏩ Glamsterdam!

Gnosis validators update your nodes!
Fulu fork in 7 hours 🔥
Apr 13
Validatoooors!
The Fusaka hard fork is right around the corner, and keeping your node current is the best way to support Gnosis Chain's security and the road to Fusaka.
👉 Epoch 1714688 , Tue Apr 14 2026, at 12:06 UTC 👈
If you're still running an older version, now is the time to update! It's a simple, few-click process.

Ethereum should not adopt the Poseidon hash for the foreseeable future.
ZK provers can deal with EL hashing, we it’s unclear the benefit of efficient proofs for consensus clients

Vibehouse: The New Ethereum Consensus Vibecoded Client by @dapplion from Lighthouse
Vibehouse is an Ethereum consensus client built almost entirely by AI agents. Forked from Lighthouse, it shipped a complete ePBS implementation in under 72 hours — all spec tests passing, finality on a multi-node devnet. This talk covers how vibecoding works for consensus-critical code and what happens when you let AI ship a hard fork.

I'll present ~Vibehouse~ at ETHDenver Thu 19 11:15am
The client is already running Gloas ePBS on a multi-node local devnet implementing ZK execution validity proofs and other fun features!

Introducing ~vibehouse~
An Ethereum consensus client with zero devs, Lighthouse v8.0 fork, that ships faster, breaks things sometimes, and accepts feature requests from literally anyone.
Participate in the experiment and open an issue!

I'm running an experiment to mantain an Ethereum consensus client with no devs,
only ~vibes~ and opus 4.6

Openclaw is so frustrating for sustained dev work...
I just want a simple Ralph Loop that communicates to me over Telegram. 75 lines of bash, no deps can do that, and it's not frustrating :) Try it out

We've released Lighthouse v8.0.0-rc.0!
The next Ethereum upgrade Fusaka is coming to testnets! 🎉 This upgrade is a major step forward for scaling L2s with more blobs 🦓
If you’re running a holesky / hoodi / sepolia testnet node, you must upgrade before the fork.

Counter-argument from Ethereum core developer @dapplion, sharing a personal view, on why EIP-7732 may not be right for Glamsterdam.
Lion argues that enshrining proposer-builder separation today is unnecessary, and if we aim to scale in the short term, we can implement EIP-7732 without trustless payments.

I am dissenting from @sigp_io to reject EIP-7732 (ePBS) as Glamsterdam headliner
If we want to scale big in the short term, we can implement EIP-7732 without trustless payments

Ever stared at 500k lines of blockchain node code wondering where to even start? We've been there. Reviewing core node implementations can be particularly challenging due to their complexity and scale.

Woke up at 6AM to ramble about EIPs and watch Ethereum hardfork into Pectra
🫡🔥
So much value in this fork, and now we'll 10x scaling
Fundamentals have never been stronger
