Overview

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

Revenue instance defines recipients of an income. Coins are send to a revenue account. Upon request or configuration change collected coins are distributed between recipients. Share of the income is declared by using recipient weights. Each recipient is ensured to be paid before the configuration is changed. This means it is not possible to for example remove a recipient 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 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(revenueID []byte) (weave.Address, error)

RevenueAccount returns an account address that is holding funds of a revenue with given ID.

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 DistributeMsg 

type DistributeMsg struct {
	// Revenue ID reference an ID of a revenue instance that the collected fees
	// should be distributed between recipients.
	RevenueID []byte `protobuf:"bytes,1,opt,name=revenue_id,json=revenueId,proto3" json:"revenue_id,omitempty"`
}

DistributeMsg is a request to distribute all funds collected within a single revenue instance. Revenue is distributed between recipients. Request must be signed using admin key.
