Ethereum needs an open protocol to support L2 interoperability.

Enter Espresso Testnet 5: Cappuccino.

As an important step towards building a permissionless & neutral system, we have expanded Espresso's finality layer to 100 nodes.

Cappuccino is fully available to the public and rollups can get started integrating and testing functionality. Our partners @calderaxyz & AltLayer will soon be deploying demo Arbitrum stack rollups on Cappuccino.

We’ve also added support for @arbitrum fraud proofs in Cappuccino.

This ensures the protocol will be ready for Arbitrum Orbit chains as Espresso nears a production launch.

Cappuccino is focused on HotShot—a fast finality layer that rollups can share for much quicker confirmations than the Ethereum L1 provides.

As such, HotShot enables fast bridging and more seamless interoperability between rollups.

Espresso’s fast finality layer is a complement to the Espresso marketplace design: proposers in the Espresso marketplace bid for the right to order rollups' transactions.

Rollups can opt into and out of selling their sequencing rights on the marketplace at any time.

The Espresso marketplace supports rollups in maximizing the value they create and capture while also enabling a more seamless interoperability experience for developers and users. A more unified Ethereum.

With Cappuccino, we’re one step closer to our first production launch.

We are collaborating with Blockdaemon, Informal Systems, KudasaiJP, LinkPool, P2P, Sub7, ZK Validator, Figment, Nethermind and Unit410 to support us in running 100 geographically distributed nodes for HotShot consensus across 6 continents.
