prev_hashstring
The hash of the ledger immediately preceding this ledger.
sequencenumber
The sequence number of this ledger, and the parameter used in Horizon calls that require a ledger number.
successful_transaction_countnumber
The number of successful transactions in this ledger.
failed_transaction_countnumber
The number of failed transactions in this ledger.
operation_countnumber
