Upon receiving an alert that Root has proposed an Identity Block signified
by a confirmed transaction from Root with the appropriate Cloutchain
encoding prefix your software must initiate the following steps:
-Verify that the Identity Blockchain Tip has been extended, and that
the Block Header Hash included in Root's propoasl transaction is a match.
-Check the newly proposed Identity Block's validity using the following
steps:
	-Make sure the Cloutbase Reference message refers to the Cloutbase Reward
txid which accepted the previous Identity Block.
	-Make sure the Cloutbase Reference timestamp is more recent than
the previous Identity Block Header timestamp.
	-Make sure the Cloutbase Reference Digital Signature is Root's valid signature.
	-Make sure the proposed Identity Block Header contains the previous Block Hash.
	-Make sure the proposed Identity Block Header timestamp is more recent than the
Cloutbase Reference timestamp.
