# VTokenomicsParams

The key parameters of the VirtuSwap Reward Formula are:

r - The compound rate of duration of reward boost calculation

b - The reward boost coefficients for locking VRSW per unit of locking time:

α (alpha) - Parameter describing the importance of LP token staking in reward boost computation

β (beta) - Parameter describing the importance of VRSW staking/locking in reward boost computation

γ (gamma) - Parameter describing the curvature of reward boost for locking VRSW as a function of locking duration,

The default values of the parameters are as follows:

r  = 0.693 / ((365 \* 8 + 366 \* 2 ) \* 24 \* 60 \* 60) *(that's 0.693 / {number of seconds in 10 years})*

b = 1 / {number of seconds in 10 years}

α = 1

β =0.5

γ = 1
