It is somebody he found a vulnerability on POW mining and exploited it.
In fact @arhag has discovered it and has already informed the devs.
There is already a fix ready on github that will take effect on the next hardfork https://github.com/steemit/steem/issues/256
You can see more details on channel #mining at https://steemit.chat/
Yup, I just got a POW in about 30 min on my normal not supercomputer PC. Back in business. Full steem ahead...
Good news, thanks to all who helped make the quick fix happen
maybe spoke too soon...there was a break but now SC is back
Looks like he scaled back some miners, so other miners have a chance finding a POW block.
For the last 3 hours I've been getting ETA 1500 minutes at 24,000hps. Pretty normal. That's what I was getting a few days ago before the SuperComputing antics.
Thanks, @liondani.
Do you know when is the next hardfork occur?
Is the POW mining any different after the hardfork?
Nothing official yet about time but I assume max the next 2 days if not sooner
it will be fair again...
like before supercomputing participated ...
Thanks for the reply.
