Snapshot
A serialized copy of the full accounts state at a rooted slot, used for fast validator bootstrapping. Full snapshots contain all accounts; incremental snapshots contain only accounts modified since the last full snapshot. New validators download a snapshot instead of replaying the entire ledger history, reducing sync time from days to minutes.
