Kaspa ($KAS) reduces its mining reward every month, rather than in a single step every four years as Bitcoin ($BTC) does. The result is a smoother issuance curve, but one that pushes miners toward fee income much sooner, according to a post from @BSCNews.
Bitcoin's protocol cuts the miner reward in half every 210,000 blocks, roughly every four years. The most recent halving, in April 2024, took the reward from 6.25 to 3.125 BTC per block, per Blockstream.
Kaspa uses what it calls a chromatic emission schedule. The reward is reduced every month by a factor of (1/2)^(1/12), or about 5.6%. After 12 such cuts, the reward has fallen by half, so Kaspa effectively halves once a year without a single cliff event.
The reward began at 440 KAS per second. According to the original post, it now sits near 20.6 KAS per second, or about 2.06 KAS per block. Schedule data from Tokenradar shows the per-second reward at roughly 21.8 for the period from September to October 2026, which is consistent with a further monthly cut to around 20.6.
Kaspa sets its reward per second, not per block. That means the move to 10 blocks per second splits the same payout across more blocks, which is why the per-block figure is far smaller than the per-second figure.
Because Kaspa's reward halves four times as often as Bitcoin's, transaction fees will have to make up a larger share of miner income much sooner. Bitcoin's halving affects only the subsidy, not fees, which depend on demand for block space. The same logic applies to Kaspa.
Most of the supply has already been issued. The original post puts about 27.75 billion KAS in circulation out of a total supply of roughly 28.7 billion. Spark Money reports that over 27.5 billion KAS had been mined by mid-2026, around 96% of the cap.
The front-loaded issuance has been a point of debate. One analysis noted that some investors worry miners create constant sell pressure when large amounts of a coin reach the market quickly. How fee revenue develops as the reward keeps shrinking will be a key test for Kaspa's long-term security model.
