Ampleforth (formerly known as Fragments) is a digital asset decentralized protocol for smart commodity money. The Ampleforth protocol aims to achieve price-supply equilibrium in response to its price deviation from the $1 target to achieve the equilibrium needed to reduce volatility. According to the magnitude of exchange rate fluctuations in the past 24 hours, the number of tokens held by each person is increased or decreased proportionally. Ampleforth is an asset with elastic supply attributes, which can relieve the pressure of cyclic trading and generate an asset price with a lower correlation with Bitcoin.
