a group called "MakerDao" is working on a token on Ethereum called Dai, which is backed by collateral in the form of a variety of different tokens, and is set up so that the price will target some multiple of something called "Special Drawing Rights", which is a basket of national currencies. I think eDollar is (was?) going to be (is?) something backed with Dai, which would target the value of USD . (I have not kept up with it, so I don't know what the state of eDollar is.)
