Grpl is an elastic supply token which uses Fibonacci correction levels as a formula in the Rebase system. It pushes the natural mathematical will of the people to do the most beneficial thing for the group, based on the fibo correction levels at the target price. It provides Nash Equilibrium, or fair distribution of income, this way. It is also designed to maintain a price target of one gram of gold.

Grpl uses two different rebase systems. First, calculations are made by basing fibo prices as the target price. In this way, target prices which repeat each other can be created. Actually, all target prices in the first level rebase protocol are made to get closer to 0,618 golden ratio. Increase or decrease at the circulating supply is determined by this rate. When the rates between target prices match the 0,618 golden ratio, second rebase formula is applied.
