#83 - Andrew Fitzgerald: Designing Solana Validator's 1.18 Scheduler, Transaction Games

Scraping Bits

In this episode, Andrew Fitzgerald from Solana Labs discusses the design of the new scheduler in Solana validator version 1.18, which aims to improve transaction processing and network congestion. He dives into the technical details of the central scheduling thread, the scheduling algorithm using a "prio-graph", and how transactions are intelligently assigned to worker threads based on account locks. The episode provides insights into Solana's innovative architecture for achieving high throughput and low latency, even under heavy transaction loads. Fitzgerald also touches on the unique challenges of blockchain transaction ordering and potential transaction "games" that validators must account for.
