This is a more narrowly focused version of WFC 403 with decision deposit placed.

v2 timed out as there was no decision deposit.

Note if allowing OpenGov to change the parameters of the burn is factored into the update to the inflation pallet it is redundant.

Background

Within the current design of Kusama and Polkadot protocols there exists a treasury and a burn mechanism, designed to incentivise the spending of accrued funds.

If the treasury ends a spend period without spending all of its funds, it suffers a 2% burn of its funds - currently standing at around 250k KSM.

This design was implemented to encourage spending and to hopefully avoid running up a large balance.

In the current 6 day spend period on Kusama 501 KSM / $8.69K will be burned unless it is utilised via spending proposals.

10% of the 2% burn (equating to 0.2% of the treasury) is redirected to the Kappa Sigma Mu society account.

The problem

This current design is hardwired into the pallets, and cannot be adjusted/controlled via OpenGov or the previous generation of calls - instead it requires a runtime upgrade.

Allowing OpenGov to changet the parameters

Given the philosophy of OpenGov to offer ultimate control of the protocol to tokenholders, it seems uncontroversial to enable this parameter to fall under the oversight of on-chain governance.

How that might work

From Hitchhooker in comments of v2.

*The burn parameters are currently set here *

*It should be quite trivial step to make the BurnDestination configurable on runtime/governance as part of the new inflation pallet. *

This WFC also covers the possibility of setting a different target for the burn.

    // Step 3: Use the configurable burn destination
