Sig: Read-Optimized Solana Validator Client
summary
Sig is a read‑optimized Solana validator client built from scratch that implements an accounts DB, block store, and shred collector and runs on mainnet while keeping databases in sync. It replaces hotspot hash maps with a cache‑friendly Swiss‑table style index, achieves account read performance of 1.5–4× and write of 1.1–6× versus agave, and serves shreds via a geyser pipe exceeding 30 Gbits/s on consumer hardware.
