question: what happens with the rewards of node operators if the interest is lowered by Hive witnesses?
I've came across this question as well. I'd say the best solution is have a static percentage that is always expected and build off of that. For example interest is 20%, but we can safely assume it'll never go below 8% (making up numbers here), thus everything should be structured around that as a basis. The additional 12% is just a bonus that can be saved up for the future or just burnt (TBD). Combining an expected interest rate with scaling RCs based on total HBD generated (not necessarily staked) will ensure there is enough HBD to cover infrastructure costs... However, in general I don't foresee infrastructure costs being a problem in the first place due to extremely lightweight node operation.
Thanks for your answer!
Why would you burn HBD? I'm sure another use case can be found for the excess, if it would be the case.
Yeah of course. I'm giving one possible option. Most likely that extra 12% will partially go to a devfund for longer term development of the project.
