I finally got a chance to send myself some coin using the new darksend. It really is elequent! So simple, so clean, It's pure genius!
You can see here, I sent myself 5.25 coins. One of the 3 transactions in the first table belongs to me. Then below, you can see my 5.25 coin going to the address I sent it (well, actually that's not the address I sent it to,it's a type of dummy address, I'm guessing), and the 4.749 is my change, that came back to me minus .001 transaction fee (again with some kind of dummy address). I don't understand how these "dummy addresses" work, or if they're what I think they are? I'm wondering if our wallets create two types of addresses that correlate to each other? It's taking me a while to learn this, LOL
From my wallet, it all looks normal, it's all done automatically. Just beautiful! None of the links in explorer actually have any wallet addresses, that is the kind that start with X. I'm not sure if our wallets create hidden addresses now or what? Regardless, this is a thing of beauty, truly!
Whenever you send coins, it sends all the coins in the input/s given, sending your change to a new address. The point of this is so that an attacker cannot re-broadcast a valid transaction extra times to cause it to be executed multiple times, emptying an address. As the input is one particular output, and it is fully consumed when spent, any attempts to re-broadcast would only be referring to no longer redeemable inputs, and would be rejected.
What would you suggest running on a 7970?
core clock between 1050 and 1150, mem clock 1250, 256 worksize, -g 2, --lookup-gap 2, intensity 13 will get you running around 2.1Mh/s completely stable.
