In an email reply I received from Slush inquiring about the abnormally high invalid blocks he responded by stating "it was a matter of chance to end up with invalid block".  And additionally stating "We don't have direct impact over this behavior.  Invalid blocks are natural part of the Blockchain ecosystem..."

Do all of you agree with this?

There will always be *some* chance involved in orphan blocks.  But he's lyingdishonest in saying that you don't have direct impact over the behavior.  If your orphan rate is above ~1%, you have something wrong.


EDIT:  9 of his last 200 blocks have been orphaned.  There is CLEARLY something wrong with either the hardware, software, or network level for Slush.

Pool should be more reliable to this kind of issue...

For the last fews days we got really bad luck, combined with TOO MANY orphans.

I see a lot bad luck from slush but not so many lucky nowadays...  Maybe -Ck is right and they have a real network issue at this point.

With all the recent Dashboard issue and the 1.3 orphan per day rate... Something is wrong.

I wonder if Slush would ever compensate their top Miner  for this mess up... I Can't imagine running 1PH and not wanting to go straight to Slush HQ after LOSING more than 10BTC in revenue in the last week from invalidated block.

/Rant


I would really like slush to fix the Luck % right after an invalidated block...

80% for this day is not right. It's like 52% according to my (weak) math.

Not good for huge hash power either!!!!!

IF AT LEAST those orphan were buried under a piles of Great Luck.... But it's quite the oppposite

I hope someone can Kick the box again and fix the luck  xD



Last 72 hours have been VERY terrible...
And the luck rating INCLUDE, all the past invalid block. So imagine that....

Still below 50% for 3 days straight.... For a 30 PH pool? BAH.

Yes.

They might implement nmc deposit soon, but right now it's the way it is.

I received another reply today from Slush regarding the recent influx of invalid blocks.

Quote
Thank you for pointing our attention to this situation. We understand your disappointment and are ready to provide you with more detailed explanation, please read below.

The primary reason for this behavior was recent malleability attack on Bitcoin network which caused the Bitcoind overload with transactions and directly affected the ability to propagate blocks into the network.
Not only our nodes were affected but many other nodes across entire BTC network as well.

Bitcoind 0.11.1 which was released 4 days ago contained bug fixes for these malleability attacks. We were testing it in the meantime in order to make sure we do will not cause any harm on our infrastructure and do not affect the
hash rate of our miners. We were stuck between a rock and a hard place these few days. But the unacceptable rise in number of invalid blocks forced us to act quickly. We would like to assure you that the new version of Bitcoind was successfully deployed on every node we use for our mining and blocks propagation. As a consequence we expect significant reduction in invalid blocks appearance in the next few days.

We hope you understand our struggle with the malleability attack and stay with us despite few bad days.
We are quick learners and are taking lessons from this experience which is going to have positive effect on your experience with our pool in the future

Which is what I said.

Well, probably that in combination with bitcoinds that haven't been optimised to cope in this transaction spam environment which can cause massive mempool and cpu blowouts and subsequently very slow block changes/getblocktemplate calls.

In other words slush hadn't manage to optimise his bitcoinds to cope under the circumstances and ended up depending on the newer bitcoind version to fix it. While he says many other nodes were affected, there were pools that were not.

That said.

I'm removing all my hashing from Slush.
Sorry, thought for sure you were one of the best pool!

But this is unacceptable.
Pay the fucking orphan, until then i'm out.

I won't be the stupid fuck that stay around in front of such a situation.

Slush at its current state is unreliable. Mine at your own risk? Dev won't share the risk with you that's for sure.
