How does Kaspa's block reward decrease over time?

Kaspa's block reward shrinks smoothly every month rather than dropping sharply all at once. During the chromatic phase, the reward started at 440 KAS and is reduced each month by a fixed factor — specifically (1/2)^(1/12) — so that after twelve monthly reductions the reward is exactly half what it was a year before. The name comes from music theory: the ratio between consecutive monthly rewards is identical to the frequency ratio between two adjacent semitones in a tempered chromatic scale, and a full year of reductions is called an 'octave.' For a beginner, this matters because it means Kaspa's emission schedule is predictable and gradual — there is no sudden halving event that can shock miners or the market overnight.
