Functions

func MergeInflationParams added in v1.2.0 

func MergeInflationParams(
	partial inflationtypes.MsgEditInflationParams,
	inflationParams inflationtypes.Params,
) (inflationtypes.Params, error)

MergeInflationParams: Performs a partial struct update using [partial] and merges its params into the existing [inflationParams], keeping any existing values that are not set in the partial. For use with [Keeper.EditInflationParams].

func NewMsgServerImpl added in v1.2.0 

func NewMsgServerImpl(keeper Keeper) types.MsgServer

NewMsgServerImpl returns an implementation of the inflation MsgServer interface for the provided Keeper.

func NewQuerier added in v1.2.0 

func NewQuerier(keeper Keeper) types.QueryServer

NewQuerier returns an implementation of the types.QueryServer interface for the provided Keeper.

Types

type Hooks 

type Hooks struct {
	K Keeper
}

Hooks implements module-specific calls (epochstypes.EpochHooks) that will occur at the end of every epoch. Hooks is meant for use with with `EpochsKeeper.SetHooks`. These functions run outside of the normal body of transactions.

func (Hooks) AfterEpochEnd 

func (h Hooks) AfterEpochEnd(ctx sdk.Context, epochIdentifier string, epochNumber uint64)

AfterEpochEnd is a hook that runs just prior to the first block whose timestamp is after the end of an epoch duration. AfterEpochEnd mints and allocates coins at the end of each epoch. If inflation is disabled as a module parameter, the state for "NumSkippedEpochs" increments.

func (Hooks) BeforeEpochStart 

func (h Hooks) BeforeEpochStart(ctx sdk.Context, epochIdentifier string, epochNumber uint64)

BeforeEpochStart is a hook that runs just prior to the start of a new epoch.

type Keeper 

type Keeper struct {

	// CurrentPeriod: Strictly increasing counter for the inflation "period".
	CurrentPeriod collections.Sequence

	// NumSkippedEpochs: Strictly increasing counter for the number of skipped
	// epochs. Inflation epochs are skipped when [types.Params.InflationEnabled]
	// is false so that gaps in the active status of inflation don't mess up the
	// polynomial computation. It allows inflation to smoothly be toggled on and
	// off.
	NumSkippedEpochs collections.Sequence

	// Params stores module-specific parameters that specify the blockchain token
	// economics, token release schedule, maximum supply, and whether or not
	// inflation is enabled on the network.
	Params collections.Item[types.Params]
	// contains filtered or unexported fields
}

Keeper of the inflation module. Keepers are module-specific "gate keepers" responsible for encapsulating access to the key-value stores (state) of the network. The functions on the Keeper contain all of the business logic for reading and modifying state.

func NewKeeper 

func NewKeeper(
	cdc codec.BinaryCodec,
	storeKey storetypes.StoreKey,
	paramspace paramstypes.Subspace,
	accountKeeper types.AccountKeeper,

func (Keeper) AllocatePolynomialInflation added in v1.1.0 

func (k Keeper) AllocatePolynomialInflation(
	ctx sdk.Context,

	err error,
)

AllocatePolynomialInflation allocates coins from the inflation to external modules according to proportions proportions:

Returns:

  • staking: Tokens minted for staking inflation that go to the decentralized validator set and delegators. This is handled by the `auth` module fee collector.
  • strategic: Tokens minted to the Strategic Reserve, the root account fo the x/sudo module.
  • community: Tokens minted to the Community Pool, which is managed strictly by on-chain governance.

func (Keeper) CirculatingSupply

func (Keeper) Sudo added in v1.2.0 

func (k Keeper) Sudo() sudoExtension

Sudo extends the Keeper with sudo functions. See x/sudo.

These sudo functions should: 1. Not be called in other methods in the module. 2. Only be callable by the x/sudo root or sudo contracts.

The intention behind "Keeper.Sudo" is to make it more obvious to the developer that an unsafe function is being used when it's called. x/sudo: https://pkg.go.dev/github.com/NibiruChain/nibiru@v1.1.0/x/sudo/keeper
