Well, maybe something like an ethereum on-chain dollar ETF and a decentralized oracle for determining the exchange rate, which is built out of bonds that allow people to get leverage against the underlying ether currency in exchange for providing collateral for the ETF. The problem with such a construct is that (1) the people providing the collateral will insist on high fees and (2) the amount of collateral provided will need to be limited for enough people to participate, so the design would always have a risk for a "broken peg" during extreme fluctuations.

It's not quite the same thing, but Stellar allows the implementation of pegged Assets (e.g. USD), though they are issued by an anchor that you must explicitly trust to redeem those deposits. That could be a bank or other well-capitalized institution however.

This is basically the BTC Tether model, except hopefully some anchors will step up that can actually complete an audit without breaking up with their auditors.

I'm not all that convinced that it will be possible to create a stable synthetic blockchain asset without either explicitly pegging to fiat (a la Stellar) or having a big and diverse enough slice of GDP flowing through the system so that speculative activities are a minority of transaction volume.

This is more or less how DAI works. And in the case of a broken peg, there's a global settlement option that can liquidate all the collateral. https://developer.makerdao.com/dai/1/stability
