His wording makes it sound like that, but someone asked whether they had any prototypes that were actually hashing at all and Josh said no:
Inaba, I guess you didn't see my question yesterday. Does BFL have a working (hashing) prototype ASIC miner?
No, we are waiting on our ASIC chips right now, as I've stated in a number of other places, though it's understandable if you have missed the posts, since they are spread out everywhere.
Admittedly that was a week ago, but he was using similarly confusing language back then too. For instance,
he said: "We are waiting on the bulk chips from the foundry, that is really the major delay right now" as though there were some previous non-bulk chips, which apparently don't actually exist.
You have to look very carefully at the question and how it is asked. There are 2 questions here. Did you create and test a prototype? Is this prototype still running on MainNet (or has it ever?) The only way Josh would answer True to the compound question would be if they still had a prototype running. If they had a prototype that is no longer running then his answer would be correct, even though it was not what we were looking for.
Given the number of threads accusing BFL of mining on MainNet I can't be too annoyed that he wanted to put a nail in that half of the coffin.
At this point it is too late for much, so I'm not going to worry about it.
