In this episode of Latest Development, Dirt sits down with Nick Pennie, co-founder of Helius, to break down their newest release: LaserStream—a game-changing streaming infrastructure for Solana.
LaserStream solves one of the most frustrating problems for developers: how to reliably stream account and transaction state in real time—without disconnects, missed blocks, or manual recovery. Nick explains how it works, why it matters, and how Helius is setting the bar for developer tooling in the Solana ecosystem.
