IF they were mining with the chips, they wouldn't be so stupid to do it on their own pools or under their own names.
Is it possible to see/track the origins of blocks generated by looking at BlockChain.info?
There was a guy a day or two ago on BFL forums and Reddit claiming that he saw a ton of Blocks coming from Kansas. The accusation coming from the guy on Reddit was that it was BFL using mining hardware.
You can use this site to look at the last 2000+ blocks found:
http://blockorigin.pfoe.be/blocklist.phpFind the ones that were found by an "unkown" entity. Click on the blockchain link to see the information of that block located on the far right.
It says what IP address found that block on that page on blockchain.info "relayed by: xxx.xxx.xxx.xxx".
Then you would need to proceed to look up where that IP is located at a web site like this one:
http://www.iplocation.net/Oooohh, Thanks.
I have the perfect software to sort through this. Will start chewing on it to see what I find.
