Block chain has been temporarily fixed and blocks are now being produced again.
The blockchain was never broken, the 4K difficulty block was finally solved, and the coin is currently back functioning as we would all like it.If you don't believe me, try to find the 4k diff block on the block explorer... hint: it should be somewhere around 296707 where there was a 4 day gap.
You are welcome.
As it happens .. I -did- wonder about that ..
You can see TWO next blocks
