We are looking to go full POS and I am giving a helping hand but may be a while as I am also working 60 hr weeks cooking in a restaurant.
We are hashing things out but I want to do a static POS reward vs a flat reward percent per year. The reasoning for me was that you need competition and if you have something like 5% total inflation but divided by the stakers, the ones participating gain more. With a flat reward per year, if you don't have everyone staking, you don't gain that inflation per year and exchanges can more easily out stake and sell the coin.
