CRDS (Cluster Replicated Data Store)
Also known asCRDS
Cluster Replicated Data Store—the data structure underlying Solana's gossip protocol. CRDS uses a push/pull model where validators exchange versioned, signed records (contact info, vote state, epoch slots). Records have wallclock timestamps and are pruned when stale. Each record is keyed by (source pubkey, label).
