With The Merge now firmly behind us, protocol builders have been making progress throughout a (file?) variety of areas over the previous few months. Withdrawals, danksharding, EOF, verkle tries, historical past expiry, SSZ and extra have all seen important progress lately!
To be able to assist transfer every of those threads ahead, and to run via yet another collection of Shapella stress exams, consumer group members gathered in particular person for a week-long interop occasion in Austria: Edelweiss 
In contrast to Amphora, which had a singular give attention to The Merge, this occasion had two main tracks, centered on the Shapella and ProtoDanksharding community upgrades respectively. A number of breakout classes have been additionally held to dive into different open issues. Here’s a transient overview of what was completed, in addition to hyperlinks to artifacts from the workshops & ongoing dialogue threads.
Shapella
The week started with a Shanghai/Capella mainnet shadow fork. Flooding the community with withdrawal credential replace messages revealed efficiency points on the community, and led to a unique consensus-layer queueing design to course of these messages.
All through the week, further devnets have been launched and stress examined with giant quantities of credential updates, withdrawals, and even dangerous blocks. Consumer implementations ended the week hardened and prepared for the fork on the newly-launched Zhejiang testnet.
Assuming the Shapella improve occurs with out subject on Zhejiang, the Sepolia and Goerli testnets will probably be upgraded subsequent!
(Proto)Danksharding
The principle EIP-4844 interop purpose was the launch of an all-client EIP-4844 devnet. By Friday, all however one consumer have been syncing on the community!
A number of design discussions additionally happened in the course of the week, stemming from a transaction pool design proposal. Questions round permitting “blobless” 4844 transactions, if and the way blocks & blobs must be coupled for gossip and easy methods to encode these transactions have been mentioned extensively and surfaced on final week’s AllCoreDevs Execution Layer name.
Over the following few weeks, groups hope to finalize all spec adjustments ensuing from these discussions and launch a brand new devnet.
EVM Object Format (EOF)
After having been conditionally accepted after which faraway from Shanghai, EOF was one of many matters the place opinions about the most effective path ahead diverged essentially the most.
Whether or not EOF ought to ban code introspection, purpose for a minimal deployment ASAP, and even solely ever go stay on L2s have been all mentioned in the course of the week.
No concrete specification got here out of the workshop, however groups now have a shared understanding of the design area and potential paths ahead. The EOF breakout rooms resumes subsequent week to proceed this dialog!
All the pieces Else
Apart from these three matters, groups mentioned the way forward for gentle shoppers on the community, how the EL & CL specs processes might converge (and doubtlessly carve out ERCs from different EIPs), launched a brand new Verkle Trie testnet, put ahead a proposal to SSZ encode EL transactions, mentioned altering the validator EL->CL deposit mechanics, and even began a Capella annotated spec!
Subsequent Steps
Lower than per week after the occasion, consumer groups have begun discussing Shapella timelines for testnets. Preserve an eye fixed out on this weblog, in addition to on shoppers’ repositories, for bulletins within the coming weeks!
For different efforts, similar to EIP-4844, EOF, SSZ, anticipate to see energetic design discussions within the coming weeks, resulting in prototype implementations afterwards.
Shapella is sort of right here, and Dencun is obvious on the horizon
