Any biometric would probably be good enough, but to satisfy the second point, it would probably have to be a combination of more. The problems would would really be the opposite, not how to create a unique hash for a person, but how to recreate it, because scanners are not precise enough etc and you'd be locked out. The real problem of course  is 3, there  could be a decentralized system that would recognize your biometric data as that datatype, but you could always (in principle imo) spoof it with similar data. At best you could make a system that would employ many different solutions against spoofing and get a high probability of a unique person. For this person to have a fixed identity would again be impossible to solve with certainty and a whole other set of solutions against swaping/trading accounts would have to be developed.

Gold price (the amount of gold behind 1 XAUR in $) determines the minimal possible market price and the production price (or market price if higher) determines the amount of $ that must be invested in gold to produce new money supply and increases the gold price.

there is a tutorial on xaurum.org

No, you'll need to download the ethereum wallet.

BTC price increases the prices of altcoins, xaurum price increases and surpasses production price, because it is above production price no market buy is necessary, and the funds that would go on the market go into the gold reserves instead.

Easily accessible information is itself the good and the bad. The problem is that the information is unstructured and isn't tied to reliable sources and people are not very good at discerning relevance and validity, we're just at the start of its self-regulation though, and it will become much more like newspapers and tv.

Good concepts, bad referral links. I hope it isn't a new No Man's Sky...

Yes, BTC price increases, and in return we get more gold.

very nice summary

any  fast way I can get up to speed with the current plan, because I've seen that the wp is outdated?

The % are not fixed, it depends on the market price or production price. Creation of 1 new XAUR requires the gold that the existing XAUR already represent, and the additional gold is the value between this value and the production price of XAUR or market price, if it is higher than production price.

If you had 1000 XAUR you would get additional 0.0609 g of gold at the last mint. 10 btc is around 80k XAUR, so about 80x that would be around 5g .

The first ones are exchanges, the RICO web, and the masternodes (the firms that are part of the Xaurum coinage process). Xaurum seems to have a very wide distribution.
