Types ¶

type Config ¶

type Config struct {
	Capacity                 gas.Gas   `json:"capacity"`
	Target                   gas.Gas   `json:"target"`
	MinPrice                 gas.Price `json:"minPrice"`
	ExcessConversionConstant gas.Gas   `json:"excessConversionConstant"`
}

Config contains all the static parameters of the dynamic fee mechanism.

type State ¶

type State struct {
	Current gas.Gas `json:"current"`
	Excess  gas.Gas `json:"excess"`
}

State represents the current on-chain values used in the dynamic fee mechanism.

func (State) AdvanceTime ¶

func (s State) AdvanceTime(target gas.Gas, seconds uint64) State

AdvanceTime adds (s.Current - target) * seconds to Excess.

If Excess would underflow, it is set to 0. If Excess would overflow, it is set to MaxUint64.

func (State) CostOf ¶

func (s State) CostOf(c Config, seconds uint64) uint64

CostOf calculates how much to charge based on the dynamic fee mechanism for seconds.

This implements the ACP-77 cost over time formula:

func (State) SecondsRemaining ¶

func (s State) SecondsRemaining(c Config, maxSeconds uint64, fundsRemaining uint64) uint64

SecondsRemaining calculates the maximum number of seconds that a validator can pay fees before their fundsRemaining would be exhausted based on the dynamic fee mechanism. The result is capped at maxSeconds.
