This is very interesting, thank you for submitting it. Will study it soon and perhaps provide feedback.
I love the idea of a stablecoin based on Decred. I think this would fit well with future plans to create a DEX. I'm a little confused though. Can you explain how “Stakeholders in this cryptocurrency supply price information to the protocol through a PoS mining process"? Does this mean that PoS miners would vote on prices? Or that they would vote on an API to pull prices from? Or something different? Thanks for the proposal
To vote on this work we first need to have Politeia working on mainnet. It's about to enter public testing.
