Red Alert! supercomputing Is Back!

• Exactly one week after the Hardfork, supercomputing aka gxt-1080-sc is back.
  This time, he is changing the computation of the nonce. He may be using a short cut or a GPU miner.

• Unfortunately, I can not upload any images to steemimg site at the moment, so I can not provide images to show the different between his and a regular miner.

• But, anyone could take a look at supercomputing's miner and compare to your own. as you can see the different is the nonce.

• On Hive account@arhag' post. He has pointed out the original exploit and the vulnerability of the fixed.
  The new mining algorithm (as of hardfork v0.13) and step 1 is about the nonce.

1) d         = SHA256(miner_account_name || latest_block_id || nonce) 

• Clearly, supercomputing has managed to find a short cut to his advantage again. Hat's off to him. (Edit: for his finding not for his mining)
  *Edit to removed the hat's off image.​

• As of right now. He already added 50 miners. He will take over the miner queue again very soon. :(

UPDATE:

Thanks Hive account@arhag for his comment.

Here is his comment from below:

I've explained the likely reason for that in the #mining channel on steemit.chat.From what I've seen, my only conclusion is that he is most likely not using an exploit, but rather using his own more efficient custom implementation of the miner. If we take his account name at face value, it likely means that he has built a GPU miner.
