Too much mystification around this Lyra2REv2 optimized miner Anyway, we bought this optimized miner from the developer that contacted us and offered us to sell the miner to us. He never used his real name so we can't confirm his real name and thus can't mention him as an author ... anyway he never even asked to be mentioned. But he is a good dev and already working on other improvements. And since we like open source we put the sources online - even if we could only put binaries (we always release source, the only case when we don't release the source is when we only buy binaries).
We are however a bit disappointed on you, sp_ ... you grabbed the public source and put it into your private miner (greedy) - now this is really not nice, you should put it in your public github repo and make a new public release.
Anyway, keep on hashing
Best regards,
