Treasury Pallet

The Treasury pallet provides a “pot” of funds that can be managed by stakeholders in the system and a structure for making spending proposals from this pot.

Overview

The Treasury Pallet itself provides the pot to store funds, and a means for stakeholders to propose and claim expenditures (aka spends). The chain will need to provide a method to approve spends (e.g. public referendum) and a method for collecting funds (e.g. inflation, fees).

By way of example, stakeholders could vote to fund the Treasury with a portion of the block reward and use the funds to pay developers.

Terminology

• Proposal: A suggestion to allocate funds from the pot to a beneficiary.
• Beneficiary: An account who will receive the funds from a proposal iff the proposal is approved.
• Pot: Unspent funds accumulated by the treasury pallet.
