Welcome to Observer #15

Ethereum Core Dev (ACD) & L1

1/ @nixorokish TOMORROW ACD #155

1/6

ethereum's upcoming Thurs protocol development call: ACDC #155
17 Apr 14:00 UTC

Suspiciously quiet agenda...
Confirming Pectra mainnet client release readiness and finalizing Fusaka's CFI'd EIPs. Fork scope is a "soft" final, with a couple items needing clean-up

2/ @mikeneuder dives deep on blobs

mikeneuder.eth ⟠

@mikeneuder

happy tax day

– to celebrate, here is a deep dive on blobs. we start by examining the L2 transaction lifecycle. this motivates a discussion on blob gossip and validation pre- and post-PeerDAS. we conclude by looking at possible mempool upgrades!

Pectra Rundown

1/ Ethereum’s next hardfork is set to go live in a couple of weeks.

It ships 11 impactful EIPs, bringing:

Doubled DA capacity

Major UX improvements

Enhanced core protocol security and utility

Here’s what’s coming and why it matters

4/ @nixorokish updates roadmap

nixo.eth 🦇🔊🥐

@nixorokish

Updated with the Pectra mainnet date

5/ @nero_eth on execution dependencies in blocks

Toni Wahrstätter ⟠

@nero_eth

In my new post, I explore execution dependencies in Ethereum blocks:
ethresear.ch/t/execution-de…

TL;DR: Most blocks are highly parallelizable, though a few contain complex dependency chains.
Summary below

ethresear.ch

Execution Dependencies

Execution Dependencies Thanks to Julian, Ignacio and Ben for feedback and review. TL;DR: Most Ethereum blocks are highly parallelizable. On average, 60–80% of transactions are completely independent,...

6/ @nixorokish Fusaka EIPs (@ Call notes)

nixo.eth 🦇🔊🥐

@nixorokish

Today's All Core Dev call agreed on a set of EIPs to Consider For Inclusion ("CFI") for Fusaka and Declined For Inclusion ("DFI") the majority of the EIPs proposed for the fork

The reason for this is devs want to ship PeerDAS (which is Scheduled For Inclusion, "SFI") as quickly

9/ @rudolf6_ on cross-chain messaging

joshrudolf.eth

@rudolf6_

only a few key pieces are needed to solve 95% of Ethereum's crosschain UX today

crosschain messaging is one (to let smart contracts on different chains talk to each other)

ERC-7786: brings messaging standards together under a unified API

This Weds April 16th: discuss & debate

11/ @0xstark tokenized treasuries are built on ethereum

Josh Stark (0xstark.eth)

@0xstark

since it wasn't mentioned in the thread or article, FYI most of that increase was on @ethereum

Laura Shin

@laurashin

On April 2, the day of Trump’s tariff announcement, the total tokenized treasury market was worth $4.85 billion.

Since then it has added another $1.01 billion, good for a 20.8% increase in under 2 weeks.
