From their docs:
* Expansion : When the price_exchange_rate
of AMPL > 1 USD
the market is indicating there is more demand than supply. In response the Ampleforth protocol automatically and proportionally increases the quantity of tokens in user wallets, gradually bringing price down to its target.
* Contraction : When the price_exchange_rate
of AMPL is < 1 USD
the market is indicating there is more supply than demand. In response the Ampleforth protocol automatically and proportionally decreases the quantity of tokens in user wallets, gradually bringing price up to its target.
Because the Ampleforth protocol transfers the volatility of demand rather than attempting eliminate it altogether, AMPL cannot break by natural market forces and does not require any collateral, treasury, market-maker, or buyer-of-last-resort to return to its long-run target.

Just curious about people’s opinions on it as a potential replacement for UST
