## Summary
While PoS inflation can currently be up to 1% per year, in reality only a fraction of the existing coins participate in the minting process.
This RFC will seek to continuously adjust the PoS block reward such that PoS inflation approximates to 1%/year on average, no matter how much PoS participation there is.
In general, this RFC will look into the intricacies of tying a block reward to the total supply, as well as how to safely implement a fluctuating block reward and a static block reward in tandem.
