Kaspa Block Subsidy Reduction: KAS Next Tier Drops Reward by 5.6%
2026-10-29
Kaspa's block reward is about to shrink again. Based on current estimates, the next scheduled step, projected for around November 4, 2026, cuts the subsidy by roughly 5.6%: from 2.06017223 KAS to 1.94454365 KAS per block. This is not a surprise event or a vote. It is one more step in Kaspa's fixed, monthly emission schedule. Here is what changes, what doesn't, and why it matters for holders, traders and miners.
Key Takeaways
The cut is about 5.6% per step. The per-block reward moves from 2.06017223 KAS to 1.94454365 KAS, and the per-second subsidy from 20.60172230 KAS to 19.44543648 KAS. Twelve such steps add up to one halving.
The date is an estimate. The schedule advances by network progress (DAA score), not by the calendar, so November 4, 2026 may shift by a day or more.
Supply is already 96.77% of the way to its cap. Circulating supply was about 27.78 billion KAS on October 26, 2026, against a roughly 28.7 billion KAS maximum, and the cut slows daily issuance by about 100,000 KAS.
What Is the Kaspa Block Subsidy Reduction?
The block subsidy is the newly created KAS that miners receive for adding blocks, separate from transaction fees. Kaspa lowers this subsidy on a predictable monthly schedule, and the next step reduces it by about 5.6%.
According to TokenPost and EconoTimes, the per-block subsidy moves from 2.06017223 KAS to 1.94454365 KAS, and the per-second subsidy from 20.60172230 KAS to 19.44543648 KAS. The projected date is November 4, 2026.
*Daily emission figures follow EconoTimes' calculation and assume the per-second rate holds for a full day.
A note on wording: the "tier" label comes from news coverage. Kaspa's own documentation describes a continuous monthly decay rather than separate tiers, so each "tier" is simply the next monthly step.
How Does Kaspa's Chromatic Emission Work?
Kaspa multiplies its per-second subsidy by 2^(-1/12), about 0.943874, once a month. That is a cut of about 5.61% each step, and after twelve steps the subsidy is exactly half.
Key design points:
Per-second, not per-block. The schedule fixes how much KAS is created each second. The per-block reward is that amount divided by the block rate.
Block rate doesn't change total issuance. Since the Crescendo upgrade (KIP-14), Kaspa produces 10 blocks per second instead of 1, so each block carries a smaller share of the same per-second subsidy.
Smooth, not sudden. Instead of Bitcoin-style halvings every four years, Kaspa applies a small cut every month.
No tail emission. The schedule runs for roughly 35 years, until about 2057, after which miners rely on transaction fees.
Kaspa's emission began in two phases. After the November 7, 2021 mainnet launch with no premine, an initial phase paid a fixed 500 KAS per second. The chromatic phase began around May 2022 at 440 KAS per second and has declined monthly since.
The implementation in the open-source rusty-kaspa client uses a table of 426 monthly values, where a "month" is 2,629,800 seconds (30.4375 days). To understand the technology behind the network, see Bitrue's explainer on Kaspa's GHOSTDAG protocol.
Why Is the Date Only an Estimate?
The reduction triggers by DAA score, a measure of network progress, rather than by a fixed calendar date. TokenPost and Pluang both note this, so November 4, 2026 is a projection.
In practice, the date can drift slightly depending on actual block production. Treat November 4 as "around the first week of November," and check a live Kaspa explorer if timing matters to your trading or mining plans.
What Does the Cut Mean for Kaspa's Supply and Inflation?
Because the cut lowers new issuance, Kaspa's inflation rate falls with it. Using the figures above, daily emission drops from roughly 0.00641% of circulating supply to roughly 0.00605%.
These percentages are our own arithmetic, based on the circulating supply figure from Kaspapulse and the daily emission estimates above:
Where does supply stand? Circulating supply was about 27,776,348,075 KAS on October 26, 2026. Against the roughly 28.7 billion KAS maximum, that is about 96.77%, leaving around 924 million KAS still to be issued over the coming decades.
Two cautions. First, the 28.7 billion maximum is an empirical estimate that the schedule approaches over time, not a constant written into the code. Second, a lower issuance rate does not by itself move price. Demand, liquidity and market conditions matter far more.
How Will the Reduction Affect Kaspa Miners and Hash Rate?
Miners earn less KAS per unit of hash power after every step, regardless of price. A 5.6% lower subsidy means a miner running the same hardware earns about 5.6% less in block rewards, before fees and before any change in network difficulty.
What miners track:
Revenue per hash. Lower subsidy and rising network difficulty both reduce KAS earned per terahash.
Electricity cost. Katpool notes that electricity cost per TH becomes the dominant factor as rewards decline.
Fees. Transaction fees are separate from the subsidy and make up a growing share of miner income over time, though no source we reviewed quantifies fee revenue today.
KAS price. If price rises, it can offset the cut; if it falls, the squeeze is larger.
ViaBTC's August 2026 worked example is a useful reminder of how profitability is calculated. It modeled a 40 TH/s machine drawing 3,080 W at $0.05 per kWh, with KAS at $0.02887 on July 12, 2026. ViaBTC itself calls this a dated example, not a current conclusion.
What about hash rate? We could not find a reliable current network hash rate figure, so we don't forecast one. Historically, less profitable miners may switch off when margins tighten, which can slow hash rate growth, but the effect of any single 5.6% step is hard to isolate.
Should Traders and Investors Care?
Yes, as one input among many. The schedule is public and fully predictable, so the market can price it in well before November 4. Most analysts treat emission cuts as a long-term supply factor, not a short-term trading signal.

FAQ
When is the next Kaspa block reward reduction?
The next step is projected for around November 4, 2026. The exact timing depends on the network's DAA score rather than a fixed calendar date, so it may shift slightly.
How much will the Kaspa block reward fall?
About 5.6%. The per-block reward moves from 2.06017223 KAS to 1.94454365 KAS, and the per-second subsidy from 20.60172230 KAS to 19.44543648 KAS.
Is this a Kaspa halving?
No. It is one monthly step in a continuous decay. Twelve steps, each about 5.61%, add up to one halving, so the subsidy halves roughly every year.
What is Kaspa's maximum supply?
Roughly 28.7 billion KAS. This is an empirical figure that the emission schedule approaches over time rather than a hard-coded constant, and circulating supply was already about 96.77% of it in late October 2026.
