Hi, everyone. Laura here. I'm actually on vacation this week, so we have a special guest host stepping in, Christine Kim. Christine has been covering Ethereum's roadmap for years, and she sat down with core developer Preston Van Loon to dig into the upcoming Fusaka upgrade. What's inside it, what it means for users, and how it affects layer twos and client teams. It's a great conversation, and I'm excited for you all to hear it. Enjoy. Are you a builder who needs to add on chain trading to your product? The Uniswap Trading API from Uniswap Labs offers plug and play access to some of the deepes
Historically, we've moved quite slow by design. Right? Like, it's there's just a lot of moving parts here. And the fact that we can get two in one year is really impressive because it means, like, people are finding a rhythm and, like, getting through. And what I'm hearing from my peers, other core devs, I'm not hearing excessive burnout. This isn't like, oh, we just worked twice as hard because we were already working 110%.
Hey, everyone. Welcome to this special episode of Unchained. I'm Christine Di Kim, the host of the Ready for Merge podcast and the writer of the ACD After Hours and BTC Before Light newsletters. I'm very excited to host this episode of Unchained, because we're gonna be talking about the Fusaka upgrade, is coming up very, very soon. And I'm joined by a very good friend of mine, Preston Babloon, the founder of Prismatic Labs and, a full time client developer for the Ethereum consensus layer client, Prism. So hi, Preston.
Yay. Happy to be here with you.
Yay. I'm glad that, we're doing this episode together because as I was just mentioning before we started this recording, when I was ideating the show or this episode with the Unchained team, we knew we wanted to talk about Fusaka and also give it a little bit more of a focus on how Fusaka is going to impact l twos. And uniquely, the Prism client is maintained by off chain labs, which builds Arbitrum and L two. So I feel like, yeah, you have a really like, you're in a position where you're building the L one, but have, like, very close access to like a major L2 that you're building?
Yeah, I would say that Arbitrum or Optane Labs is our biggest customer. So we care deeply about what's happening in L2s and how we're improving and impacting them. So there's a lot to talk about here in Fusaka. This is a really exciting upgrade.
Yeah. Let's I wanna talk about the specific impact of Fusaka on l twos, but very generally, let's talk about the kind of, like, biggest EIPs or biggest impacts coming up from the upgrade. So Fusaka, as we were talking before the up for the corona has about 12 EIPs in it. Can you give an overview of, like, the main features, the biggest impact of this upgrade on various Ethereum stakeholders? Like, give us the bird's eye view of this of this major upgrade.
Yeah. I think that almost all these are very exciting. There's some that are like more, I don't know, maintenance level EIPs. But this is a very exciting EIP set because we have a really interesting headliner called Pure DOS. And the theme here is blobs, right? We're trying to scale the data layer of Ethereum through blobs and do it in a way that, you know, keeps it practical to run an OM and to keep the decentralization going and keep the home staker alive and at the same time scaling scaling the data layer, scaling the L1. There's a little bit of both in this upgrade. And if you like, we can
