And at current hashrate we need to stop mining after a block for one and a half day writing for that pool to do two blocks.
Except that web it comes to mining you have thousands of eyes watching those blocks and what their miners and the pools are doing, the moment farms keep mining blocks that are not broadcasted not validated you will have red light flashing everywhere! Also there is a huge difference between getting data from a server and reconfiguring it.
The ca$$h takeover of hashrate, that one I can believe it, the other not so much.
Slush was obviously just an example. A sign im behind the times perhaps, But irrelevant
The 2nd quote I'm not sure how to respond to as you are clearly not familiar with how these attacks are carried out.
The moment farms keep mining blocks that are not broadcasted not validated you will have red light flashing everywhere!
Sure there are miners out there who actually monitor what their miners are doing and would notice it moving on to new blocks but 99.99% wont and the ones that do will take time to get their word out. Then those people to move their hashrate. You only need 4 blocks with most exchanges.
That brings up another good point. Which large scale miners actually have monitoring in place for this? I doubt its standard across the industry. I know for a fact it wasn't when I was more involved and mining was even further centralized to a few pools.
This is all hypothetical of course as the risk of two or more major pools getting pwned and then the pwner deciding to carry out this specific attack are very minimal. I dont want people thinking I lose sleep over this, its certainly not a major concern now but if mining further centralizes into a handful of pools then the threat grows.
