Any example of how to implement the new VerificationController and the constant KNOWN_TRANSACTIONS_KEY?

I was looking at introducing a new VerificationController for checking in-app purchases: http://developer.apple.com/library/ios/#releasenotes/StoreKit/IAP_ReceiptValidation/_index.html

And I wonder if there is any example where you can verify the transaction, since it seems that it is - (BOOL)verifyPurchase:(SKPaymentTransaction *)transaction;not enough, and it must be implemented internally to verify the purchase when the data is generated on the server.

Another question: does anyone know what KNOWN_TRANSACTIONS_KEY is and how to fill it out, is this just the product identifier of the purchase?

When it comes to

 KNOWN_TRANSACTIONS_KEY

and

ITC_CONTENT_PROVIDER_SHARED_SECRET

I would also like to know why they are needed, and why and when they are needed.
