Not speaking for them, but it's pretty simple... take 995M coins out of circulation at any given time... set walls... done
Ah !
The penny is finally starting to drop with me thanks to your more-informative-than-any-other-documentation post

So the peg's going to be enforced by creating a synthetic market where supply to market is restricted and demand is driven up by redeploying some of the IPO Bitcoin that's in reserve ? (A bit like an IBM shares buyback where - because they've no viable business profits - they buy their own shares without issuing any new ones to drive up the price and justify their bonuses).
It would be good if all of this stuff could be documented in one place rather than having to pick it up piecemeal. I got the "eBay" smart contracts stuff from the thread header, the coin supply restriction bit from a couple of darkened room videos that somebody randomly posted and the boosted demand bit from you.
Ok, you've given me something to think about now. I appreciate you making that post and supplying a missing piece of the jigsaw. I had seen other posts about IPO money being kept for "walls" but they were all out of context. I didn't get that it had an actual strategic function within the peg mechanism as opposed to simply supporting the price for the sake of it.
(P.S. Don't mind my dig about IBM - we have to retain a sense of humour in all of this if we are to take such ambitious plans seriously at the same time

).
