Ampleforth is an innovative cryptocurrency designed to maintain purchasing power stability through its unique protocol. Originating in 2018, it deploys a mechanism known as a stable supply economic model rather than a stable price model. Unlike traditional stablecoins pegged to fiat currencies, Ampleforth adjusts its circulating supply daily based on demand, without directly controlling price. This elastic supply mechanism ensures that one AMPL has upon average the utility of 2019's purchasing power. By doing so, Ampleforth seeks to provide a non-correlated asset that hedges against inflation and deflation, making it a versatile component in diversifying cryptocurrency portfolios. The protocol's smart contracts autonomously adjust the token quantity in an AMPL holder's wallet, ensuring all changes are completed proportionally.
