The Ledger Object

When Horizon returns information about a ledger, it uses the following format:

• ATTRIBUTEDATA TYPE

  DESCRIPTION

• idstring

  A unique identifier for this ledger.

• paging_tokennumber

  A cursor value for use in pagination.

• hashstring

  A hex-encoded SHA-256 hash of this ledger’s XDR-encoded form.

• 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

  The number of operations applied in this ledger.

• tx_set_operation_countnumber

  The number of total operations in the transaction set (including failed transactions).

• closed_atstring

  An ISO 8601 formatted string of when this ledger was closed.

• total_coinsstring

  The total number of lumens in circulation.

• fee_poolstring

  The sum of all transaction fees.

• base_fee_in_stroopsnumber

  The fee the network charges per operation in a transaction.

• base_reserve_in_stroopsnumber

  The reserve the network uses when calculating an account’s minimum balance.

• max_tx_set_sizenumber

  The maximum number of operations validators have agreed to process in a given ledger. Since Protocol 11, ledger capacity has been measured in operations rather than transactions. For more info on that decision, see CAP-5.

• protocol_versionnumber

  The protocol version that the Stellar network was running when this ledger was committed.

• header_xdrstring

  A base64 encoded string of the raw LedgerHeader xdr struct for this ledger.
