Blockstore
A RocksDB-based database that stores raw shreds and block metadata on the validator's disk. Blockstore indexes shreds by slot and shred index, enabling block reconstruction and historical queries. It is separate from AccountsDB—Blockstore holds the ledger history while AccountsDB holds the current state.
