Begin-Block
Minting parameters are recalculated and inflation paid at the beginning of each block.
NextInflationRate
The target annual inflation rate is recalculated each block. The inflation is also subject to a rate change (positive or negative) depending on the distance from the desired ratio (67%). The maximum rate change possible is defined to be 13% per year, however the annual inflation is capped as between 7% and 20%.
NextInflationRate(params Params, bondedRatio sdk.Dec) (inflation sdk.Dec) {
inflationRateChangePerYear = (1 - bondedRatio/params.GoalBonded) * params.InflationRateChange
inflationRateChange = inflationRateChangePerYear/blocksPerYr
// increase the new annual inflation for this next cycle
inflation += inflationRateChange
if inflation > params.InflationMax {
inflation = params.InflationMax
}
if inflation < params.InflationMin {
inflation = params.InflationMin
}
return inflation

NextAnnualProvisions
Calculate the annual provisions based on current total supply and inflation rate. This parameter is calculated once per block.

BlockProvision
Calculate the provisions generated for each block based on current annual provisions
BlockProvision(params Params) sdk.Coin {
