Re: block reward schedule proposal

Having a tail-emission will definitely be something mimblewimble will need
to keep miners incentivized for long term network security.

This is a pretty brilliant emission scheme. It would make for a very fair
coin distribution where late adopters to mimblewimble would not feel
greatly disadvantaged compared to 'early' adopters of the coin.

while this may be true, it may also be desirable to establish a constant
block reward after x epochs so that in the far far future the tail
emission is still attractive for miners to secure the network.
