+     - The version number of this broadcast protocol message which is equal

+       be before this individual will accept the message. This number is the
+       average number of nonce trials a node will have to perform to meet the
+       Proof of Work requirement. 1000 is the network minimum so any lower
+       values will be automatically raised to 1000. This field is new and is
+       only included when the address_version >= 3.

+       be before this individual will accept the message. This number is added
+       to the data length to make sending small messages more difficult.
