Thanks for your comments and thanks for putting forward an alternative (apart from different parameters). This helps people to make up their mind.
Let me first say that I don’t have an opinion right now on changing the spending cycle but it appears to me a bit off-topic, because I don’t see how it is correlated with any change to the inflation system. This might be better discussed somewhere else.
Regarding your proposal on a fixed token issuance
While I am not strictly opposing the idea, I am not convinced how this makes things easier to understand than a percentage-based inflation relative to total issuance. The latter guarantees a stable APY for stakers (at least within the staking rate, but that’d affect your model, too). And this is the metric that nominators are focusing on and from where the system derives (some) of the economic security (by paying validators). Having a fixed token issuance would reduce total inflation and APY over time. It might take some time for this to become meaningful (but then also for it to become effective?), but eventually the fixed token inflow would be dwarfed by the total issuance and we’d need to transition to a new system.
I’d further argue that the simplified model I am proposing is making it already much more intuitive and it’s not an argument to come up with an even simpler model (while I stated above that I even disagree its simpler). I also don’t think it’s fair to assume that people are too stupid to understand it. “Memeability” in that regard is not more important than having a stable security budget.
As I said, I don’t strictly oppose the idea, but I don’t see how it gives us any benefits. If you want to make your proposal more convincing, it would good to provide some justification for the initial parameters (total inflow) and make some projections about the future. This should be done within the framework that we are discussing (i.e., treasury inflow, staker APY, and total inflation). For example, your proposed “25M DOT per Year” is difficult to compare to my proposal on a glance, but translates to 1.64M DOT per 24 days.
A last note: I completely disagree that we should divert any funds from coretime sales to the Treasury. I am sure you are familiar with my reasoning, but for others interested, here is the approved RFC that is stating some arguments.
In my opinion, we should strive towards a system where we have “inflation” in terms of new token issuance to pay for public goods (i.e., Treasury and Security), but have a counterweight to it by burning coretime. Hopefully, and that takes time to see, we can scale the available blockspace so much that individual coretime is affordable but collectively accrues sufficient burns.
