Title: Did we just lose a dark pool?
Post by: Puppet on October 18, 2013, 08:30:47 AM
Im slightly confused looking at the network hashrate graphs. First I thought it was just statistical variance, but its been going on for too long now. The past 4-5 days hashrate has been flat or even down slightly.

Yet at the same time, we know KnC is cranking out >100TH per day and if you look at the pool stats, they all seem up significantly. BTCguild, eligius, Slush, ghash.io, they have added several 100TH to their hashrate over the past few days.

Whats up with that? Did someone turn off a large private pool or something?

perhaps a handful of big solo miners found out that it isnt profitable to solomine so they turned to pools or people who found out that thanks to the difficulty increase, its no longer profiable so they turned off their asics

Very few, if any asics would be turned off at this point. The vast majority is still at least marginally profitable, and even if they werent, they would be sold and start hashing elsewhere. What has become unprofitable (gpu's, fpga's,..) is so marginal in hashrate that you wouldnt notice it.

Now it is possible some big solo miners joined pools, but that still leaves me slightly baffled that the hashrate is seemingly flat or a tad down when, bitfury and KnC (and in all likelyhood, even BFL) are constantly adding significant amounts of hashing power.

Maybe someone was testing out a pool, and was satisfied things were working alright before deploying on a larger scale? Or maybe the person who's mining the testnet is doing so by mistake..

This is very interesting... hmm.

Maybe the NSA got fed up with the rising difficulty rates?  :D

Avalon just shipped out 500x60gh and whatever amount of 4 module avalons they have been selling, could account for some of it ;)

It could be variance.
~<20 big miners, high difficulty etc.

Mining equipment gets turned off when it goes in transit to the next sucker that it was sold to on ebay.

That would be a continuous process, I see no particular reason why that would have happened with several 100 TH at the same time, and with hashrate that wasnt present on any of the major pools.

Seeing short term average just shot through 3PH, perhaps it was just a statistical anomaly after all

Or that big data centre that uses half a million dollars of electricity a month is doing more than just storage, its been having some power issues lately ;)

I guess it doesn't do much at the moment
