Kaspa (KAS) Mining Calculator
Kaspa is a proof-of-work cryptocurrency built on the GhostDAG protocol, which processes multiple blocks simultaneously (a "blockDAG") rather than a single chain. This allows for extremely high block rates — currently 1 block per second — without sacrificing security or increasing orphan rates. Kaspa uses the kHeavyHash algorithm, which underwent rapid ASIC development in 2023–2024, transforming the network from GPU-mined to predominantly ASIC-dominated within 12 months.

Best Hardware for Kaspa Mining
Kaspa ASIC mining in 2026: Antminer KS5 Pro (21.5 TH/s, 3,150W, ~147 W/TH) — Bitmain's current flagship KAS miner, best efficiency tier; IceRiver KS5L (20 TH/s, 3,400W, ~170 W/TH) — high hashrate but slightly less efficient; Antminer KS3 (8 TH/s, 3,188W, ~399 W/TH) — mid-range option, widely available on secondary market; IceRiver KS3M (6 TH/s, 3,400W) — entry-level ASIC, only viable at very low electricity costs. GPU mining Kaspa has been economically unviable since ASICs saturated the network in late 2023–early 2024.
About Kaspa Mining
Unlike Bitcoin's sudden four-year halvings, KAS uses a <strong>smooth emission curve</strong> that reduces daily rewards by approximately 50% annually — equivalent to a continuous, daily micro-reduction. This creates predictable, plannable revenue decline for miners rather than overnight cliffs. The tradeoff: KAS mining economics change continuously, which makes running current calculations essential before committing to hardware purchases.
As of 2026, Kaspa has one of the most active ASIC ecosystems among altcoins, with competitive hardware from both Bitmain (Antminer KS series) and IceRiver. Network hashrate has grown substantially since ASIC launch, meaning early GPU miners who held their hardware have largely been priced out — but ASIC operators with sub-$0.06/kWh electricity remain well within profitable territory.
Kaspa's BlockDAG and Fast Blocks
Kaspa is built on the GHOSTDAG protocol, a blockDAG that processes many blocks per second instead of one block every several minutes. This delivers near-instant confirmations while preserving proof-of-work security, making Kaspa one of the fastest PoW networks in operation.
For miners, the high block rate means rewards arrive in small, frequent increments, smoothing variance compared with slow-block chains. Kaspa uses the kHeavyHash algorithm, which after 2024 became the domain of dedicated ASICs.
kHeavyHash ASICs and Kaspa's Emission
Kaspa launched fairly with GPU mining, but purpose-built kHeavyHash ASICs from IceRiver and Bitmain (the KS series) now dominate the network, sharply raising hashrate and pushing GPUs out. If you are evaluating Kaspa today, an efficient kHeavyHash ASIC is effectively required to stay competitive.
Kaspa's emission follows a smooth "chromatic" monthly reduction rather than abrupt halvings, with issuance decreasing by a fixed factor each month. This gradual, deflationary schedule means your KAS-denominated rewards decline predictably over time, so model future emission when projecting returns.
