BULLET: BUILDING SOLANA'S FIRST ULTRA-LOW LATENCY ROLLUP

Summary from the TLDR Crypto newsletter

Bullet is Solana's first ultra-low latency optimistic rollup. It is designed to power the Zeta X decentralized exchange with CEX-level performance through its streaming sequencer model. The system achieves sub-50ms latency. It uses Solana for both settlement and data availability, with ZK fraud proofs for security and a VM-less architecture for maximum flexibility. Bullet aims to enable high-performance DeFi applications that combine centralized exchange speed with decentralization security guarantees.
