Interesting proposal. Personally I think Hard Forks to explore different models are perfectly fine as Bitcoin and Grin are in its essence also just experiments. Some people might become more interested in this hard fork since it makes Grin feel more interesting as store of value althoug arguably the difference is purely psychological.
My support for the linear supply model of Grin will stay the same as I think it is a vital requirement for a fair distribution of Grin and a requiremt for any money to be used on a day to day basis. I always feel conflicted when spending Bitcoin since I want it to be used as day to day money while knowing hodling would be the sensible thing to do from a financial point of vieuw.
If we are prosing hard forks to look at alternative emission rate’s, I personally would be more interested to see how a linear inflation rate would work.
So for example 5% inflation every year. For example the after the first 2 years the emission rate becomes N * 2^0.0704 with N being the number of Grin coins in circurlation.
Or better written:
First 2 years, 1 Grin/sec
After two years 63115200 * 2^(0.0704 * i) with i being the number of years
-Even better would be to write it as ( i -2*31557600)/31557600 where i is the number of seconds meaning the inflation rate is really fixed and adjustedd every second instead of on a yearly basis. And a further improvement would be to adjusted the emission rate in the 2 years to organically to go towards for example that 5% inflation rate instead of suddenly introducing it after 2 years.
Anyhow, just a thought. Does anyone know if there is cryptocurrency existing with a similar emission shedule, so a fixed inflation rate, or do I have to wait for a Central Bank Digital Coin (CBDC) with a fixed inflation rate? It would be of course better to first have a non governamental controlled cryptocurrency to explore such a model.
