BASED ESPRESSO: AD-HOC SHARED SEQUENCING FOR ALL L2S, FROM BASED ROLLUPS TO VALIDIUMS

Summary from the TLDR Crypto newsletter

Espresso Systems is developing a marketplace for shared sequencing that will enable L2s on Ethereum to sell block space. The project aims to tackle the fragmentation that is happening in the Ethereum ecosystem without compromising the benefits of rollups and validiums, allowing for the unified and efficient execution of user intents across multiple chains. Espresso is also creating a decentralized finality gadget, HotShot, to improve transaction confirmation speeds and security. The goal of this is to facilitate greater interoperability and reduce transaction costs and latency for end-users.
