The "validation video" makes me very curious. I'm a transitioning trans-women and I'm expecting that my face will change a lot when I'm getting onto hormones.
How would it recognize my face again after massive changes? Have you looked at before/after hormone pictures of trans people?
Some parameters won’t change - interpupillary dissonance, distance between an eye and an ear, auricle constitution (which is as unique as fingerprints), etc. However, there certainly will be difficulties if hormonotherapy is involved.
In DCoin anyone can make money on the growth of coin volume in his wallet, and exchange them for fiat money at the 1:1 rate. At that, there is no need whatsoever to buy coins (see article for more details).
Any housewife can create new coins, thus ensuring support to the 1:1 exchange rate; all she needs to do is make a short video and take a couple of photos.
Access to the account is only possible using the private key. There is also the private key recovery function: http://en.dcoinwiki.com/Restoration_access.
However, there is a problem with twins. Only one of the twins will be able to become a miner, another will have to use a regular anonymous account.
