Please look at the witness page.
supercomputing has taking over the witness queue. I am not sure the dev care about this.
It is sad for all miners. :(

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.
Of course the devs care about this. Apparently this guy has discovered a "loophole" in the mining algorithm that enables him to outmine everyone else. @abit or @arhag can explain the technicals if they want, but anyway they already see a fix so the loophole will be closed.
What's cool about this is that it means some very smart minds are looking at the algorithm, which will only help it grow stronger.
Hats off to mr. supercomputing :)
@rainman, Is this consider a 51% or 99% attack? and can he hijack the blockchain?
No, it's not possible for a miner to hijack the steem blockchain as miners don't generate a large enough number of blocks in a round (Steem uses hybrid POS and POW for block creation).
Is the PoS part based on Steem or Steem Power holding?
I see. Thanks for the answer @blocktrades.
Or someone has developed a GPU miner and keeping it for themselves
agreed.
It's not viable for supercomputing to continue mining with rewards that can only be cashed out over 104 weeks. Most likely some rented AWS server.
good job @alphabeta. I will notify those I know about it. This post will probably get some upvotes. Like i said--good job ;)
Thank you, @officialfuzzy.
At least supercomputing is not hiding this, so prob not immediate risk. Don't the witnesses provide the price feeds?
Yes, the witnesses do provide the price feeds.
The DPoS witnesses provide the price feed, not the current mining witness.
Btw, there is no point for @supercomputing to add any more resources into Steem mining when he already dominates the queue because it is not possible to mine more than 1 block every 63 seconds anyway.
By completely dominating he is discouraging the rest of us from even trying. Why would you waste your electricity when you know it's hopeless. As miners give up and new miners are dissuade his dominance will increase. He's the fed. The only way to fix this is for someone to develop and publicly release a GPU miner.
Just shut the mining off. My desktop just can't compete. Hope someone else can give supercomputing a run for the money.
Me too. And so ends my two day excursion into steem mining. Back to nicehash.
Or for the devs to release a hard fork with new pow algo.
Agreed.
All he needs to do is to add more miners on the config.ini file.
Right now basically he is the 22nd witness, getting paid every block.
And now Miner-witness queue list is 123 long. But two weeks ago list was max 105 long. I very sad with mining. My cpu power go nowhere :\
Been mostly supercomputing and rabbit since I started mining a couple of weeks ago.
Makes you wonder if that is some kind of bot net.
doubt it. the white paper explains why this is unlikely. the hackers would have to distribute their private key with the malware and the miner requires a strong network connection which botnets lack.
Well the mining instructions say not to use the same key on more than one witness so each probably has a separate key to begin with. Just a matter of sweeping the accounts as soon as possible.
It could just be someone has installed in on every computer in some university labs or something like that too.
Each node is finding a POW in 2-3 hours. You can't do that with PC using the standard miner.
Agreed. Most likely he created a GPU miner.
I noticed supercomputing was offline for a few days last week. I guess he was testing his miner with the new software. Now he has over 118 miners.
Someone has a little too much CPU power on their hands...
I believed the miner he used has been modified.
Headline tomorrow: Steem goes viral in China
A government backed cryptocurrency?
Followed by blockstream acquires steemit.com
Did we just discover Craig Wright's supercomputer?
I also had been mining, but when looking at this, I think to continue no longer.
Once you get home, to stop the mining program.
Wow I just checked my time to produce a block. It went from 1100-2200 to 18000-36000 minutes. So min 12.5 weeks to find a block now.
Have been mining on a decent Xeon rig at about 41k/h/s for ~ 2 weeks. Haven't got close to a block. Agree devs should cycle through the lineup somehow to avoid centralization. The last thing we want is another Bitcoin-esque mining cartel... Just pick randomly from everyone that meets the minimum hash/latency and try to ensure as much as possible unique miners are selected via account names, ip addresses, etc.
