The prize is $10000 for each miner and it has to be open source. Good luck getting Claymore involved... 
That amount of $10,000 is too low for Claymore. I believe that he earned hundreds of thousands from his miners.
There are countless people who will compete for the development, he's not the god of miners.
Don't recall raising Claymore to deity status, perhaps I was drunk and forgot about that post...
The fact is, he has done well with ETH and XMR miners. No reason to believe he wouldn't build a competitive / enhanced miner for equihash (Zcash) as well.
As of now, there are no publicly available GPU miners for this algo. So a 99% dev fee would be better than what is available..
What I'm basically saying is that he doesn't have to make his own miner for us to have an awesome miner to use. Wolf0 has done well with his sgminer-gm as well, maybe a little more difficult to set up, a little less pretty but it does the job, and by investing 10 minutes of your time you can save the 1% you pay Claymore. exactly the same hashrates on Hawaii chips and an higher hashrate on my Fury X.
I don't have anything against him, he does have great miners and I have used them in the past. but I personally don't think we should use someone's closed source miner and pay him 1% of our earnings.
