Some folks suggested DJB or Wang Xiaoyun, but I doubt they'd do it for 10btc. Also doubt that Josef Pieprzyk would go for it?
I will add 5 BTC to the bounty provided we get someone who is qualified and respected (someone quote this post to make sure it is on the record).
We want someone with crypto cred more than someone with a media personality.
So now we have 15 BTC to pay for this - anyone else want to chip in?
