Espresso is developing a decentralized shared sequencer and confirmation layer to tackle the challenges of Rollup fragmentation and centralized sequencing. According to NS3.AI, the company's HotShot consensus mechanism is designed to provide rapid finality and improve censorship resistance by ensuring only confirmed blocks are settled on Ethereum. With tools and integrations spanning over 20 blockchains, Espresso seeks to position itself as a key infrastructure component within the modular Rollup ecosystem.
