whats the point of the green address if its not 100% instant?
I dont think reducing transaction time from 60 minutes to 20 minutes or whatever is gonna be much of a difference (also why things like solidcoin isnt a good solution)
It doesn't change the transaction time - it just means the receiver can trust the transaction at zero confirmations.
If all the exchanges used this, it would mean that the prices should stop lagging the mt.gox price.
The problem is, I believe, that to forward a transaction that *arrives* at the green address, it has to wait for 2 confirmations before it is able to send it to the actual recipient.
Actually, no. We produce both transactions instantly, and send the second one without waiting for confirmations.
