my first report is out! 🥹

was pretty fun to deep dive how based rollups, preconfirmations, and shared sequencing can help to fix Ethereum's liquidity fragmentation

A real preconf implementation! It's very exciting, especially because it plugs into SUAVE!

Espresso x Arbitrum Update

Two Arbitrum chains used Espresso for decentralized, shared sequencing on our latest testnet, a bridge demo between Arbitrum Nova chains was deployed, and ongoing R&D work is moving forward.

Lots of stuff brewing from Espresso in the Arbitrum (💙,🧡)…

Here I share Espresso Systems's latest thinking on marketplaces for shared sequencing and based sequencing!

Rollups, sequencers and #Bitcoin are now being mentioned in the same sentence.

So I wrote a blog on how these chains can use Espresso for sequencing and data availability.

It was so fun to part of Modular March! I really appreciate robbie and Andy 🦇 🔊 having me!

I made a quick website to visualize this: preconfirmations.vercel.app

The content is not very precise yet, so take it with a grain of salt. 🧂 I'll add more of my thoughts about preconfs to it later!

Preconfirmations (promises that users' data will be finalized on the L1) are very flexible and can promise many different things. Here are some thoughts about the key properties of preconfirmations, ranging from weakest to strongest kinds of promises for each property.…

We’re excited to announce that Espresso Systems has raised a $28 million Series B round led by a16z crypto.

I'm speaking at encrypt.xyz this Friday! I'll be speaking about how we can create encrypted mempools in shared sequencing protocols, but you should check out all the other talks, too! There should be some great, heavy-hitting content.

I love Espresso’s work all the time, but Based Espresso has me excited like nothing else. All I want to do is talk about it with people. It’s seriously so neat!

Proof aggregation and shared sequencing are very compatible! Espresso Systems will have some more content on this soon, but here is the gist:

Espresso is a marketplace for shared sequencing that ensures L2s are always better off in Espresso than they are on their own. L2s also…

Me talking to anyone about sequencing:
