Distribution Model
The Distribution Model contract manages the calculation of the ANC emission rate, using fed in deposit rate information. At the time of protocol genesis, the emission rate adjusts to double when the deposit rate is below the targeted rate and decreases by 10% if the deposit rate is above the targeted rate. Further descriptions on the ANC emission rate control mechanism can be found here.
