Mr. Unknown keeps getting bigger

[mdude77]

I'm not going to pretend I know what the 51% attack is, or how it works, but he, assuming it's one miner, is getting larger and larger every day. 

(I apologize if this is being hashed out elsewhere...)

"Unknown" isn't necessarily a single entity, and often consists of mis-identified known pool blocks.

And I guess some larger frams just go solo/mergedmined to pick up the extra 0.1% transaction fees, and also keep bandwidth down, as the daemons do not use up much. You might even use sattelite inet as backup, as the 1 second delay during backup times is not really bad. But another think. Is this the block from hell (got solved this moment (179628) ?!

Fear of the "unknown". It's a common human response.
But yeah, I'm really curious to understand exactly what makes up the unknown.
Who are they? What are their intentions?

Fpga/asic manufacturers piloting new products until they produce enough coins to them and the difficulty level rises enough, and then send their products to the people who have paid them a few weeks/months earlier.
Of course they want to be anonymous.
They also deny everything if they are asked about it

I love that conspiracy theory. I'll buy into that

If you go here http://blockchain.info/pools and scroll down to the unknown block section, you will see that it is not one person submitting all those blocks, but is a lot of different ip addresses. if you look at the ip with the most blocks submitted, you'll see that it doesn't even match the top 5 pools in terms of blocks per 24 hours.
