A run of 10 blocks, 70% of the network.
You better hope they don't keep doing that ...
Is there a reason other than the 50% attack theory?
'Theory' ... lol
I called it a theory because it requires one of the largest companies in bitcoin to either attempt to destroy bitcoin [or to be horrendously hacked] which doesn't seem likely. They'd stand to lose probably $XXX,XXX,XXX if they tried a 50%, to gain what?
No, the 51% attack isn't just an attack by evil empires.
Of course it can even happen below 51%, but once a pool hash rate gets high enough it will automatically be able to overlord the block chain.
There is advantage in being a higher hash rate, that people wont obviously notice.
Bitmain has proven their lack of giving a crap about the bitcoin community and lying (either by design or by stupidity) about what they have done.
Their p2pool project was simply a centralised p2pool that they tried to garner interest in by falsely claiming it was decentralised.
Their recent statement that expending anything on support of S1/S2/S3 is a waste of money even though they are the basis by which they became
one of the largest companies in bitcoin and most of that hardware is still out there - a lot of it not even 12 months old.
Their pool was creating empty blocks that are bad for bitcoin and I pointed that out last year and again this year ... no response about having fixed that anywhere ...
They ignored the GPLv3 license with cgminer on multiple accounts and gave internal processes being slow as their crappy excuse for violating the license in all cases when they finally did release the cgminer driver code.
They ignored the GPLv3 for over a year regarding the SPI kernel driver and have only recently released that.
[sarcasm]Yeah they have a really good track record there - of course they wouldn't do anything untoward[/sarcasm]
