So, as many know, there's been a few miner's found over the last few months, that are withholding blocks
(and some in previous years also)
Recently slush, and 2 on my pool, one who moved to BCMonster.
We are talking sizeable hash rates also.
On slush he supposedly detected it in about a month, and more than 10 blocks in a month takes a hash rate that is NOT small.
In my case I detected them using the idea organofcorti came up with.
So why am I bring this up here?
In early January I posted a short message that this proxy hash rental service has a due diligence of checking the quality of miners.
Ensuring they are not withholding. Keeping statistics on miners.
They've ignored it.
So now, if you pay for hash rate here, with an enormous 6% fee they receive for doing nothing about this, you have a chance you are paying for hash rate that will not find blocks.
They have no statistics to check if this is the case, and they get paid the 6% if the miner is withholding blocks, so they don't care.
Worse is the fact that anyone known to be withholding can simply move their hash rate to a dodgy service like this and it would be almost impossible for someone paying for hash rate to detect that they are withholding (but not difficult at all for the proxy hash rental service)
Almost impossible due to the fact that you can't identify a single miner when you pay for rental hash and if that miner withholding is 10% of the rash rate you receive, but 90% of it isn't withholding, it would take something in the order of over 100 Blocks worth of hashes (over 100 network difficulties of hashes) to detect the withholder if you mined that way continuously for all that time with that withholder being 10%, since you can't (yourself if you pay for hash rate) determine what % of the hash rate you pay for is from the withholder.
The proxy service can of course detect and monitor this.
I strongly warn anyone paying for miners on this proxy hash rental service, that you are at real risk of being provided with mining power that will not find blocks.
Dear
kano, once again you're sticking your nose into something that it is not your business. Your're calling NiceHash a "dodgy service" yet still you know very good that NiceHash is one of the most long-standing, quality, advanced, full of features crypto currency service, operating for already 2 years. We're doing full share validation, we're monitoring each single miner, blocking botnets and also doing measures to detect block withholdings. How do you know what statistics do we have and what we don't have? In the past two years several thousands miners have already been blocked from NiceHash due to various suspicious activity and as far as we can tell, none block withholdings have been done via our service, if you have proof for it, please bring it on, otherwise stick to your business. If you would write a bit more concrete, not-childish post we might take you serious, but with the tone of your post and constant negative stance against our service nobody can't actually take you serious.
NiceHash will continue to add new features, keep the excellent level of support and increase service performance to make sure our users get the
best possible hashing rental service.
Best regards,
NiceHash team.
