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!
With a view to assist transfer every of those threads ahead, and to run by yet one more collection of Shapella stress exams, shopper group members gathered in individual for a week-long interop occasion in Austria: Edelweiss 
Not like Amphora, which had a singular concentrate on The Merge, this occasion had two main tracks, centered on the Shapella and ProtoDanksharding community upgrades respectively. A number of breakout classes had been additionally held to dive into different open issues. Here’s a temporary overview of what was achieved, 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, extra devnets had been launched and stress examined with massive quantities of credential updates, withdrawals, and even unhealthy 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 problem on Zhejiang, the Sepolia and Goerli testnets might be upgraded subsequent!
(Proto)Danksharding
The primary EIP-4844 interop objective was the launch of an all-client EIP-4844 devnet. By Friday, all however one shopper had been syncing on the community!
A number of design discussions additionally befell 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 should be coupled for gossip and learn how to encode these transactions had been mentioned extensively and surfaced on final week’s AllCoreDevs Execution Layer call.
Over the following few weeks, groups hope to finalize all spec modifications 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 subjects the place opinions about one of the best path ahead diverged probably the most.
Whether or not EOF ought to ban code introspection, purpose for a minimal deployment ASAP, and even solely ever go dwell on L2s had 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!
Every thing Else
Except for these three subjects, groups mentioned the way forward for mild shoppers on the community, how the EL & CL specs processes might converge (and probably carve out ERCs from other EIPs), launched a brand new Verkle Trie testnet, put ahead a proposal to SSZ encode EL transactions, mentioned changing the validator EL->CL deposit mechanics, and even began a Capella annotated spec!
Subsequent Steps
Lower than per week after the occasion, shopper groups have begun discussing Shapella timelines for testnets. Preserve a watch 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, count on 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
