-// MsgPing implements the Message interface and represents a bitcoin ping
-// message.
-//
-// For versions BIP0031Version and earlier, it is used primarily to confirm
-// that a connection is still valid.  A transmission error is typically
-// interpreted as a closed connection and that the peer should be removed.
-// For versions AFTER BIP0031Version it contains an identifier which can be
-// returned in the pong message to determine network timing.
-//
-// The payload for this message just consists of a nonce used for identifying
-// it later.
