Espresso Systems is an EVM-compatible blockchain that provides scaling and privacy systems for Web 3 applications. It integrates a proof-of-stake consensus protocol with a zero-knowledge (zk) rollup mechanism, allowing multiple transactions to be bundled in a more resource-efficient way. Its Configurable Asset Privacy for Ethereum (CAPE) smart contract application gives creators the ability to customize privacy settings for sender and receiver addresses, as well as the amount and type of assets held or in movement, making them public, private or only transparent to select parties.
