Espresso Systems is a blockchain infrastructure project focused on enhancing scalability, decentralization, and interoperability for rollups and other chains. The core product, the Espresso Sequencer, provides a shared, decentralized sequencing layer that enables multiple L2 rollups and blockchains to coordinate transaction ordering, checkpoint state to L1s (like Ethereum), and improve cross-chain communication. Espresso leverages proof-of-stake consensus and ZK-Rollup technology to deliver a scalable, secure, and permissionless platform. The project also offers privacy solutions, such as the CAPE application, which allows customizable transaction privacy on EVM-compatible chains. Espresso aims to address centralization risks in rollup sequencers and foster a more unified, efficient multi-chain ecosystem.
