Instant transaction notification
With this feature CryptoNote transactions become real-time. When Alice broadcasts her newly created Bytecoin transaction to Bob, his wallet will immediately recognize it and update Bob's pending balance before the transaction is included in the blockchain.
I wonder, in case of double-spend attempt or transaction cancelation how will the wallet react? My question stands for GUI version also.
Suppose, nobody will make the double spend. It is really complicated to accomplish at present bytecoin version.
