It is embarrassing to see the kind of replies in this thread.

Seems like even entities like Delphi Digital overlooked some of the worrysome points

@gendelphi

As @Anjan-ParaFi mentioned, UST’s peg mechanism does have a risk of failure, however the UST peg mechanism has proved to be rather robust during torrid market environments, quickly returning to peg.

Although there were delegators like @monet-supply that didn’t do 100% Nod but still

@monet-supply

UST is backed by a volatile asset (LUNA) without any excess collateralization. imo it’s probably not suitable to be a collateral asset, but would be a great fit to add as a borrowable asset.

But it opens up as a Learning that we must not forget .

@JeremyKeating

In Iron Finance IRON was like UST and TITAN was like LUNA. It used the theoretical feedback of the price of IRON dropping making it worthwhile to burn for TITAN and vice-a-versa. Sounds like Luna and Terra. When both started dropping it led to a feedback loop that created a death spiral. Iron finance seemed to work fine and then collapsed when it went mainstream. What is different about Terra that I am missing?

But as long as we have Users that are aware of such situation . They will keep the protocol out of danger …
