I think it's PoW, because when installing the newest wallets I found a new directory NoblecoinPOS, aside the "usual" (to me) Noblecoin one. A working PoW wallet would be of great help! Shall I give you my email on private message?
Should I then send the NOBL to a PoS address? Will it work? Thanks a lot!
I hope it's a PoW one but I'm not sure.
