Struct solana_ledger::blockstore_db::columns::BankHash

source · 
pub struct BankHash;
Expand description

The bank hash column.

This column family persists the bank hash of a given slot. Note that not every slot has a bank hash (e.g., a dead slot.)

The bank hash of a slot is derived from hashing the delta state of all the accounts in a slot combined with the bank hash of its parent slot. A bank hash of a slot essentially represents all the account states at that slot.
