Interest Rate Model

APY Function
Parameters below are different based on token type (major, stable, governance...... etc).
Borrow APY
= {1 + [Base + Multiplier * min(UtilizationRate, Kink 1) + max(JumpMultiplier * UtilizationRate - Kink 2, 0)] / BlocksPerYear } ^ BlocksPerYear - 1
Supply APY
= Distribute (Interest Paid by Borrowers Per Block - Reserve) to all suppliers, and convert it into APY
= Distribute [(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] * Total Borrow * (1 - Reserve Factor) to all suppliers, and convert it into APY
= {[(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] * Total Borrow * (1 - Reserve Factor) / Total Supply}, and convert it into APY
= {1 + [(1 + Borrow APY) ^ (1 / BlocksPerYear) - 1] * Total Borrow * (1 - Reserve Factor) / Total Supply} ^ BlocksPerYear - 1
= {1+[(1+Borrow APY)^(1/BlocksPerYear)-1]*(1-Reserve Factor)*Utilization Rate}^BlocksPerYear-1
BlocksPerYear = 2,628,000 (12 sec per block)
