The Brew House is here! 🏠 ☕

We're launching a 6-week accelerator to transform the most promising crosschain projects from our Build & Brew Hackathon into production-ready apps.

- 6 teams
- Mentorship
- Expert-led workshops
- Up to $80K in funding
- July 21-Aug 29

Read on ⤵️ Our Build & Brew Hackathon showed incredible developer appetite for solving Ethereum's fragmentation:

👉 486 hackers registered
👉 156 projects submitted
👉 91 Espresso-integrated chains deployed
👉 12 apps reached Pitch Day

Many were building crosschain apps for the first time

To interoperate, L2s need to communicate.

Today, the most secure way for L2s to do this is pass messages via the Ethereum L1—but that takes 15+ min & costs $$

For interop to work well, L2s need to swap messages in seconds.

Let's explore how we can make this possible. 🧵👇 Current interop designs make key tradeoffs to speed things up:

👉 OP Superchain makes L2s trust each others' sequencers—fast, but creates interdependence & risks cascading reorgs

👉 ZKSync & Polygon have L2s swap validity proofs—scalable, but can't prevent sequencer misbehavior

After two years of R&D, five testnets & integration plans with >20 chains, we’re excited to announce the Espresso Network is now live on mainnet!

This launch is a major milestone, both for our team and along the path to making Ethereum composable again.

Read on to learn more ☕️ Our vision is for all chains to work together like one, while maintaining each chain's unique benefits.

And our mission starts with Ethereum, which promised an infinite garden of innovation before scaling challenges & a lack of infra forced L2 chains to sacrifice composability.

Kyoto 2.0 is now live on Cappuccino Testnet

Our friends at @alt_layer are back with a new deployment of their @arbitrum Orbit rollup on our latest testnet This chain is open for the public to test with transactions and application deployments

Excited to collaborate with AltLayer to help more chains seamlessly integrate with Espresso’s mainnet 🔜

As Ethereum builds a rollup-centric future, rollups are exploring how to decentralize their sequencer and improve interoperability.

To further this vision, we are building the Espresso Sequencer.

Today, we are excited to announce our second major milestone and testnet:

Doppio. As rollups horizontally scale Ethereum, they are facing two pressing challenges.

-Fragmented rollup interoperability
-Using centralized servers to decide which transactions to include and in what order (aka sequencing)

ICYMI, @aztecnetwork is selecting a decentralized sequencer for the next version of Aztec

And @EspressoSys submitted two proposals for consideration

Join us for a spaces on Aztec's plans, Espresso's proposals, and the decentralized future of L2s 🤝 twitter.com/i/spaces/1zqKV… @aztecnetwork recently published an RFP sharing their process for selecting a decentralized sequencer.

The RFP outlined requirements & design considerations, and also shared its future responsibilities in the next version of Aztec. discourse.aztec.network/t/request-for-…

Rollups are delivering on their promise to scale Ethereum & make it useful for a wider range of applications, but today rely on centralized sequencers.

We are building the Espresso Sequencer: the way rollups will decentralize.

Decentralization, censorship-resistance, privacy, and security are values that are not uniformly delivered on across Web3 products.

This is an issue we have thought a lot about in the development of our first product, CAPE.
espressosys.com/blog/user-educ… CAPE empowers asset creators like stablecoin providers or NFT artists to design policies (or custom rulesets) for the assets they offer users. Some of these policies can include:

Many great insights from policy, technology, and privacy leaders in our ongoing Twitter space—tune in here: twitter.com/i/spaces/1vOxw… @reidhoffman : we want to drive towards where technology can be modified to be part of the solution—governments need to have financial measures against criminal activities, but we need software innovation that’s not constrained by oligarchic banking systems
