Overview

Package distribution implements a revenue stream that is periodically distributing collected coins between defined destinations.

Revenue instance defines destinations of an income. Coins are send to a revenue account. Upon request or configuration change collected coins are distributed between destinations. Share of the income is declared by using destination weights. Each destination is ensured to be paid before the configuration is changed. This means it is not possible to for example remove a destination before distributing collected funds. Only an admin can alter a revenue configuration. It is a good idea to use a multisig contract as an admin address value.

This functionality can be used to pay validators for their work. It is a transparent and trustful way to split income.

Functions

func NewRevenueBucket 

func NewRevenueBucket() orm.ModelBucket

NewRevenueBucket returns a bucket for managing revenues state.

func RegisterQuery 

func RegisterQuery(qr weave.QueryRouter)

RegisterQuery registers feedlist buckets for querying.

func RegisterRoutes 

func RegisterRoutes(r weave.Registry, auth x.Authenticator, ctrl CashController)

RegisterRoutes registers handlers for feedlist message processing.

func RevenueAccount 

func RevenueAccount(key []byte) weave.Address

Types

type CashController 

type CashController interface {
	Balance(weave.KVStore, weave.Address) (coin.Coins, error)
	MoveCoins(weave.KVStore, weave.Address, weave.Address, coin.Coin) error
}

CashController allows to manage coins stored by the accounts without the need to directly access the bucket. Required functionality is implemented by the x/cash extension.

type CreateMsg added in v0.17.0 

type CreateMsg struct {

type ResetMsg added in v0.17.0 

type ResetMsg struct {
	Metadata *weave.Metadata `protobuf:"bytes,1,opt,name=metadata,proto3" json:"metadata,omitempty"`
