Kusama: Make the current inflation formula adjustable. #364

kianenigma · 2024-06-27T13:22:58Z

This PR does not alter the inflation of Kusama, but instead make the current parameters of the system fully configurable.

Parameters

The parameters are as follows:

/// Minimum inflation rate used to calculate era payouts.
pub static MinInflation: Perquintill = Perquintill::from_rational(25u64, 1000);

/// Maximum inflation rate used to calculate era payouts.
pub static MaxInflation: Perquintill = Perquintill::from_percent(10);

/// Ideal stake ratio used to calculate era payouts.
pub static IdealStake: Perquintill = Perquintill::from_percent(75);

/// Falloff used to calculate era payouts.
pub static Falloff: Perquintill = Perquintill::from_percent(5);

/// Whether to use auction slots or not in the calculation of era payouts, then we subtract
/// `num_auctioned_slots.min(60) / 200` from `ideal_stake`.
///
/// That is, we assume up to 60 parachains that are leased can reduce the ideal stake by a
/// maximum of 30%.
///
/// With the move to agile-coretime, this parameter does not make much sense and should
/// generally be set to false.
pub static UseAuctionSlots: bool = true;

All of the above are exactly the current values in Kusama, and leave everything unchanged, leading to roughly 1kKSM minted for validators, and around 90KSM for treasury.

All of the above can be changed via the Root track only.

Given that it is hard to come to consensus, I highly advise this PR (and a similar PR to Polkadot) to NOT alter any parameter and leave that to the token holders.

Just to provide one example, if we set UseAuctionSlots = false and leave everything else un-changed, the amount minted per era would be:

807KSM for staking
238KSM for treasury

This, in my opinion, is the most non-controversial change as the incorporation of auctions in the inflation rate is already meaningless with agile-coretime.

Consideration for UIs

This PR is shipped with a new runtime API that is only added to the Kusama runtime: Inflation_experimental_inflation_info. I hope this API is used by the UIs to show the inflation parameters of the network, rather than re-creating the Rust logic in the front-end.

Some updates:

Depends on Update to SDK 1.14 #381
Would also preferably depend on sdk 1.15 to get the new relay_inflation helper fn.
Based on the last fellowship call, for now we will only add this to Kusama https://www.youtube.com/live/oWppBMrgU7M?si=b4O-G_mIEBp1tnV4&t=2137

would be better if you referenced the crate name and (min) version required, instead of this PR, otherwise it becomes a non-trivial chore to figure out when this can be removed and no one will do it :)

Counterpart of #364. Similarly, it has no impact on the inflation as-is, and just exposes the params to the Root track. ## UI Consideration Similarly, it adds `Inflation_experimental_inflation_info` Runtime API, which can be used by UIs to fetch information about the inflation, without needing to rely on storage items. ## Example - With current parameters: ``` Inflation ==> staking = 402244.054 DOT (4,022,440,540,915,948) / leftover = 4178.285 DOT (41,782,856,835,356) ``` - With `UseLegacyAuctions = false`, which means we no longer set aside around 15% of tokens for auctions. This makes the difference between actual staked and ideal staking rate (staking inefficiency) grow, and therefore reduce the staking reward and increase the treasury income. ``` Inflation ==> staking = 340780.189 DOT (3,407,801,892,871,273) / leftover = 65642.150 DOT (656,421,504,843,446) ``` --------- Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Gonçalo Pestana <g6pestana@gmail.com> Co-authored-by: Ankan <10196091+Ank4n@users.noreply.github.com>
