You can simply make a proof of stake coin or a Ripple clone or a NXT clone or whatever and issue in its first block(s) all the coins the Aurora chain shows the ownership of, or issue the coins onto Ripple or other "issue custom tokens" system similarly. So yes it is fixable, but in fixing it you mgiht as well only issue to Icelanders, the whole garbage of having 50% go to foreigners is pointless wastefulness.
Yes.. i do agree with that.
I'm not sure what value there was letting foreigners mine the other 50%, other than perhaps some initial support from mining community and making some headlines. (but hey i ain't complaining.. i made a lot off mining it and sold at 150..)
Anyways should the developer chose to, he can always hard fork again to make it 100% PoS, and still use existing blockchain. Would have to distribute a versioned client, but it's always possible to go that direction...
There's multiple options to pursue... not the end of the world for this coin, in any case. Too much FUD being thrown around...
In any case, I really wish AUR and the Icelanders luck in this, It's a very important experiment for cryptos, and we should as a community support this effort.
