All three transactions are relayed by nodes in Chicago. It cannot be coincident. So I doubt it belongs to labcoin.
Most likely, next update will give us an address without coins and just for us to wait for the first block.
So if a block generation is relayed by nodes in Chicago, it means the block was found by some mining hardware located in Chicago?
No. It means that the node that first relayed the block to blockchain.info's servers was located, according to their geoip database, in Chicago. While it is possible that blockchain.info got it directly from the miner, it isn't certain or even likely that the hardware was located in Chicago. As an example, look at several of Asicminer's blocks. They come from all over. The last one came from Dallas. The one before that came from Germany. In this particular case, it is very suggestive since all three blocks came from the same geographical area, although not the same ip address.
