Is anyone else concerned that 43% of the hashrate is from an unknown source?

[davida]

I suspect a lot of this is the 1Th/s Antminer S2 rolling off the production line and waiting for dispatch on 10th April...  

Remember that the S2 has the power supply built in, so as soon as each machine is complete they will have in running right until it needs to be boxed up and dispatched.

Look back through the difficultly increase, back in oct/nov when the antminer s1 was released the difficultly was rising by 40% every 2 weeks.

They would be foolish not to mine with them for a few weeks before dispatching.

This Dave Carlson guy produces probably close to 10% of the unknown hashrate. So I wouldn't be that worried yet.

This is odd. Seems to be related to the 2^n transactions in blocks. Seems possible there's some flaw somewhere?

[Spekulatius]

31% right now. I guess it depends where you look. This is a pretty acurate site: http://blockorigin.pfoe.be/chart.php

[LAMarcellus]

I believe that unknown is actually the company "cloudhashing".
Can anyone confirm or deny?

[williamj2543]

Aww shit sorry guys. I'll tone my mining rig down a bit.

Just means that PFOE found the source of the remaining 12% hashrate.

[casinocoin]

someone is gonna be able to do a 51% attack pretty quickly..Bitcoin is over, PoS FTW!!!!

Pardon? Do you even understand how a 51% works?
Do you guys also not understand that"unknown source" is not one single miner or group..

[ryanmnercer]

Who cares. It's not one group/company/person. Even if it was, they'd be losing money with the prices where they are right now unless they are getting free electricity.

[Soros Shorts]

Oh no! A fifty-one percent attack is imminent!

This feels like ghash.io all over again, except this time there's not even a face on the potential threat..

Looks like Andreas Antonopolis is on permanent amber alet for FUD spreading Bitcointalk threads now since the whole malliability thing.

Within minutes of this thread appearing there's now a remark in red on the graph saying:

A large portion of Unknown blocks does not mean an attack on the network, it simply means we have been unable to determine the origin.

LoL !! I can just see him with his head in his hands in despair - oh jeez, another b.s. fud spreading Bitcointalk thread. Better go and do necessaries...

[Acidyo]

Oops, sorry guys. I was playing around with my settings and accidently super-duper-turbo-charged my miner...I'll go ahead and turn it down.

Thanks! You almost attacked us all.

Yeah I bet Andreas reads every single bct post.

Yes, but this should account for only a fraction of his hashrate. That's "only" around 1% of the current total network hashrate.
