Thanks! What I'm seeing is similar to what I'd expect to see from, say, Slush's mining pool - is there some way to link the TXs to an individual piece of mining hardware, or to a specific individual/organisation that controls the miner? (Apologies if it's obvious and I'm missing it, it's been a long time since I mined).

Edit: it occurs to me that an alternative is to tally up the total AntPool hashpower and compare it with what Hashnest customers believe they should be getting. Is that possible?
