As it stands if Ultra Nitro doesn't slash the hash rate, it IS INDEED AN ATTACK ON THE NETWORK.
As you are stealing completed work from other pools and thus in - effect canceling out legitimate UTC TRANSACTIONS IN FAVOR OF YOUR OWN (pretty much the very definition of a 51% attack).
"you solved that block 20 minutes ago? well F@#* YOU i just solved mine, yours doesn't count" that's what nitro essentially is doing atm.
The way the network is structured atm , there is no point in even having any other pools, and all the pools will die.
Some people are fine with that, but honestly thats not healthy for the coin, the entire idea is decentralization for the purpose of security and preventing forks.
You are attacking legitimate miners and pools causing them to slip bellow profitability thresholds required to maintain the pool, thus far other pools have been generous slashing rates, lowering %'s and doing promo periods, but they can't keep it up forever they have costs.
What kind of coin only has "one pool"?
FIX YOUR SHIT.
And if words are too hard to comprehend here is a picture.
At the very least make a "nitro 2" or something and have different work assigned to it, and use a server to balance the hash rate to different stratums to decrease orphans and possibility of forks.
Simply moving 25% of nitros hash to a "nitro2" network would improve the situation.
