Can someone tell me what the normal % of unknown is on this graph?

http://blockchain.info/pools?timespan=4days

Is 15% out of the ordinary?

I'm trying to figure out where the huge jump is...there doesn't seem to be anything out of the normal variations on this graph:

Sure there is a 3% spike in overall usage but there are similar dips and spikes previously.  I'd guess any increase over the normal variation and growth rate could be attributed to more interest in bitcoin lately rather than BFL testing equipment.

I owe my soul to the Bitcoin code...
No one ever received a full blown $30000 rig from BFL. They were automatically changed to 2 mini-rigs which are only 25.2GH/s each.

You can ask gigavps, fefox, or whitephantom about the details because they were some of the first to order the full rig.

ASIC might be coming, my feeling is they haven't had enough dev time to be testing yet

BUT fpga deliveries continue, I have heard many reports from people with recent minrig deliveries
at 40Ghash per mini rig its only 25 minirigs per 1Thash
fpga singles from bfl and other fpgas from other manufacturers continue to be delivered.
I still have people joining my pool and starting to mine on their gaming cards and cpus(!)
people are still buying 7970s and other gpus and putting them to mining,
and of course once BTC price rises it makes it viable for some marginal miners to switch rigs back on, remember it was only a few weeks ago $5 was the BTC price.

Of course difficulty will rise Smiley

It's 52g/h per minirig for everyone who preordered the old ones, people late to the show could also buy one @ 25gh. A large spike in mining like that is not a few people taking delivery of some 250mh FPGA's. BFL doesnt ship out anything quick enough for a bunch of people to get them all at the same time and turn it on anyway.

Probably not BFL since they've claimed they would not use mainnet for testing.

I don't buy that for a second. There were devices with exactly the BFL mining specs tested on a pool before shipment before. It was suspected that it was Inaba's account on a hopping pool at the time. Not sure where that thread went, but it seemed pretty damning evidence, and I don't believe it was ever explained.

My question is how likely is 3-4 TH manifesting itself within one day not due to a great number of miners, but a single actor?


Just seems fishy.

probarly BFL testing the first batch of production?

Probably not BFL since they've claimed they would not use mainnet for testing.

If it is indeed a new actor responsible for this volume then we'd have to consider their ability to further add capacity on the order of TH's.

A 10 TH spike all of a sudden. Whatever it is, it's not an accident or variation. Hopefully, it will turn out to be a 51% attack. It was a long time coming and the protocol needs to become protected against it. Bitcoin will either come out of it stronger than ever or dead.

A 51% attack wouldn't manifest itself as a increasing in hashing power.  The attacker will be hashing an alternate chain.  So either the attacker was previously hashing the main chain in which case you would see a massive drop in hashing power or the attacker was never contributing to the main chain in which case there would be no change in hashing power.

Isn't that the pool BFL has used before for burning?

Yes, it is. If the biggest miner name on the stats as a burn on it's name, it's BFL.

Beat me to it.  I'd imagine that one would think the hashrate would go the other way since coins are worth a little less now.  Instead it looks like the network's doubled.



Perhaps Largecoin may be behind this also?
