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 ☕️

Integration Spotlight #007: @EspressoSys A solution accelerating your rollup decentralization.

This is going to be massive. One of the biggest drawbacks of shared sequencers is the misalignment of incentives for rollups which *theoretically* lose revenue. In today's Modular March recording, @ellierdavidson explained how @EspressoSys flips this on its head, coming 🔜

Today we announced our Series B fundraise led by @a16zcrypto @alive_eth . Our post medium.com/@espressosys/s… reiterates the core message of my article "Based Espresso". Espresso is a marketplace for shared sequencing, designed to increase rollup composability and value capture.

This Saturday we’re going Beyond the Base Layer. Interested in L2s, rollups and the applications we can deploy on top of them? Come learn from speakers from @EspressoSys, @base, @0xPolygon, @OffchainLabs, @eigenlayer, @cartesiproject, and more.

The Espresso Sequencer exists to scale Ethereum rollups. To support this vision, we're excited to unveil our work integrating with the @Arbitrum stack. This integration is a part of our latest testnet release: Gibraltar.

It's exciting to see discussion about shared sequencing, preconfirmations, and @EspressoSys in @ethereum's Reddit AMA yesterday! My thoughts in this thread:🧵 reddit.com/r/ethereum/com…

We think a lot about rollup preconfirmations. We have been working on a design we call Byzantine Fault Tolerant (BFT) preconfirmations. In our latest blog, we explore this approach alongside Proposer-Promised preconfs, as initially described in the context of based sequencing:

The Espresso Sequencer recently released its third major milestone and testnet, Cortado. And today we are unveiling the first live, public demo of a shared sequencer. This demo not only supports multiple rollups, but multiple rollup stacks: medium.com/@espressosys/l…

Heading home from Permissionless. Great job all round @Blockworks_ and @BanklessHQ Our biggest news there was a collaboration with Espresso for the development of Timeboost ordering and shared sequencing tech compatible with Arbitrum chains. I’ve known @benafisch and…

We are thrilled to announce that we are partnering with @OffchainLabs to improve transaction ordering and to bring a shared sequencing option to Arbitrum technology chains. medium.com/@espressosys/o…

In addition to integrating with the OP Stack, we’re also excited to provide an update on our work for the Optimism Collective’s Leader Election proof of concept:

Bootstrapping a sequencer network is akin bootstrapping a validator set for L1. The two major players in the industry are @EspressoSys and @AstriaOrg Espresso also have a data availability ("DA") solution called Tiramisu, whereas Astria want to use @CelestiaOrg for DA. (9/12)

The Espresso Sequencer recently passed its second major milestone and testnet. And today, we are excited to share that Doppio is now open to the public. The ecosystem’s first public testnet for a shared sequencing layer is here: medium.com/@espressosys/o…

We are teaming up with @Calderaxyz to bring decentralized sequencing to the OP Stack 🔴✨medium.com/@espressosys/e…

Why use a separate consensus protocol for fast finality? @benafisch shares why HotShot can give users instant finality like a centralized sequencer, without trusting a single server. 📍@modular_summit


FKL Reposted

At the heart of the Espresso Sequencer lies HotShot. HotShot is a proof-of-stake consensus protocol based on the HotStuff protocol. We are pleased to share more about HotShot consensus and its integrated Tiramisu Data Availability solution: hackmd.io/@EspressoSyste

Injective is joining forces with @EspressoSys to pioneer decentralized rollups! This collaboration brings decentralization to rollups within Injective's ecosystem, including Cascade, the first @Solana SVM rollup for the Injective_ & the IBC ecosystem. injective.xyz/3NXnzrj

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.
