Type Alias moonbase_runtime::FastAdjustingFeeUpdate

pub type FastAdjustingFeeUpdate<R> = TargetedFeeAdjustment<R, TargetBlockFullness, AdjustmentVariable, MinimumMultiplier, MaximumMultiplier>;

A “Fast” TargetedFeeAdjustment. Parameters chosen based on model described here: https://research.web3.foundation/Polkadot/overview/token-economics#1-fast-adjusting-mechanism

The adjustment algorithm boils down to:

diff = (previous_block_weight - target) / maximum_block_weight next_multiplier = prev_multiplier * (1 + (v * diff) + ((v * diff)^2 / 2)) assert(next_multiplier > min) where: v is AdjustmentVariable target is TargetBlockFullness min is MinimumMultiplier

Trait Implementations

impl<T, S, V, M, X> Convert<FixedU128, FixedU128> for TargetedFeeAdjustment<T, S, V, M, X>

where T: Config, S: Get<Perquintill>, V: Get<FixedU128>, M: Get<FixedU128>, X: Get<FixedU128>,

fn convert(previous: FixedU128) -> FixedU128

Make conversion.

impl<T, S, V, M, X> MultiplierUpdate for TargetedFeeAdjustment<T, S, V, M, X>

where T: Config, S: Get<Perquintill>, V: Get<FixedU128>, M: Get<FixedU128>, X: Get<FixedU128>,

fn min() -> FixedU128

Minimum multiplier. Any outcome of the convert function should be at least this.

fn max() -> FixedU128

Maximum multiplier. Any outcome of the convert function should be less or equal this.

fn target() -> Perquintill

Target block saturation level

fn variability() -> FixedU128

Variability factor
