With The Merge now firmly behind us, protocol builders have been making progress throughout a (report?) variety of areas over the previous few months. Withdrawals, danksharding, EOF, verkle tries, historical past expiry, SSZ and extra have all seen vital progress not too long ago!

With a view to assist transfer every of those threads ahead, and to run by yet one more collection of Shapella stress assessments, 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 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 special consensus-layer queueing design to course of these messages.

All through the week, extra devnets have been launched and stress examined with massive 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 challenge on Zhejiang, the Sepolia and Goerli testnets will likely be upgraded subsequent!

(Proto)Danksharding

The principle EIP-4844 interop aim was the launch of an all-client EIP-4844 devnet. By Friday, all however one shopper have been syncing on the community!

A number of design discussions additionally passed off 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 needs to be coupled for gossip and the way 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 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 matters the place opinions about the very best path ahead diverged essentially the most.

Whether or not EOF ought to ban code introspection, goal for a minimal deployment ASAP, and even solely ever go reside 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 mild shoppers on the community, how the EL & CL specs processes may 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 every week after the occasion, shopper groups have begun discussing Shapella timelines for testnets. Maintain an eye fixed out on this weblog, in addition to on shoppers’ repositories, for bulletins within the coming weeks!

For different efforts, resembling EIP-4844, EOF, SSZ, anticipate to see lively design discussions within the coming weeks, resulting in prototype implementations afterwards.

Shapella is sort of right here, and Dencun is obvious on the horizon 🌅
