As those who have read my work on cvTokens know, I believe it is a mistake to build an entirely separate layer on top of Bitcoin, and then to build precious metal or fiat-equivalent tokens on top of that.  Backing other tokens directly in bitcoins is much easier to implement and offers access to a much larger pool of liquidity (the critical element in producing stability).  In addition, if you are committed to having trusted sources publish valuation anchors, then implementation becomes very simple indeed.

Nonetheless, it is true that the concept of provably collateralised tokens backed in a purely digital instrument is worthy of much greater attention than it has received.  So I applaud you for your efforts to catalyse some movement in this area even though I think your particular model is insufficiently developed.

Since you are eager to move this idea forward, allow me to suggest a simpler first step.  Why not launch a kickstarter for the creation of a trusted "oracle" publishing the USD price to the blockchain, with a method that requires consensus among several parties, and some simple code for helping them to achieve it?  Such a thing would surely be useful, and if it proves trustworthy and reliable you have proven the viability of a key component in your larger project.  It is also simple, deliverable, and requires no solutions in cases where only problems have been described.  In the worst case it would lend you credibility if you decide to proceed with this larger crowd-funding plan.  I wish you luck!
