Carrots are a compliance (ie. tax generation) whereby a player must purchase the item for entry into some contest (though participation in the contest itself is optional). They will typically come with an additional perquisite, such as a #mention, thus sharing congruence with pledging (carrot=pledge) in the legal definition of the word; wherein the reward [debit] is goods/monies owed [output] for payment as input. On the otherhand, a peach is the processing mechanism. (see fruut, multiplier, sticker)
/// etymology: the word 'carrot' comes from the concept of rabbiting🐇; where a person or team subjects their work to
rapid application building (rab). The word 'peach' is used here from the fruit, which has layers (fuzz, skin, meat, nut/almond) representative of varying currencies. Bottom line -- think of carrot as a 'tax' (ie. house fees) and a peach as some type of 'payment processor'.
