NegativeUNL

(Added by the NegativeUNL amendment.)

The NegativeUNL ledger entry type contains the current status of the Negative UNL, a list of trusted validators currently believed to be offline.

Each ledger version contains at most one NegativeUNL entry. If no validators are currently disabled or scheduled to be disabled, there is no NegativeUNL entry.

Example NegativeUNL JSON

    }
  ],

NegativeUNL Fields

In addition to the common fields, the NegativeUNL ledger entry has the following fields:

Name	JSON Type	Internal Type	Required?	Description
`DisabledValidators`	Array	Array	No	A list of `DisabledValidator` objects (see below), each representing a trusted validator that is currently disabled.
`LedgerEntryType`	String	UInt16	Yes	The value `0x004E`, mapped to the string `NegativeUNL`, indicates that this entry is the Negative UNL.
`ValidatorToDisable`	String	Blob	No	The public key of a trusted validator that is scheduled to be disabled in the next flag ledger.
`ValidatorToReEnable`	String	Blob	No	The public key of a trusted validator in the Negative UNL that is scheduled to be re-enabled in the next flag ledger.

DisabledValidator Objects

Each DisabledValidator object represents one disabled validator. In JSON, a DisabledValidator object has one field, DisabledValidator, which in turn contains another object with the following fields:

Name	JSON Type	Internal Type	Description
`FirstLedgerSequence`	Number	UInt32	The ledger index when the validator was added to the Negative UNL.
`PublicKey`	String	Blob	The master public key of the validator, in hexadecimal.

NegativeUNL Flags

There are no flags defined for the NegativeUNL entry.

NegativeUNL ID Format

The ID of the NegativeUNL entry is the hash of the NegativeUNL space key (0x004E) only. This means that the ID is always:
