Prop 141: Kava Horizon signaling proposal

This proposal implements the first phase of Kava Horizon, that all kava emissions (including POS rewards, Kava Rise rewards, and other various reward emissions) shall cease in perpetuity at Dec 31, 2023. Rewards accumulated to Kava Origin and the community pool will be the source of all future rewards (POS rewards, Kava Rise, etc). A future software upgrade proposal will implement the change in reward flows. The parameters in this proposal will set the reward schedule between now and Dec 31, 2023.
