Kaspa (KAS) launched in November 2021 and uses the KHeavyHash proof-of-work algorithm. It's one of the fastest blockDAG networks — producing blocks at ~1 per second. KHeavyHash is GPU-friendly but ASIC miners (like the Antminer KS3) now dominate the network hash rate.
GPU mining Kaspa remains viable at low electricity costs. The RTX 4090 achieves ~3.8 Gh/s and the RTX 3080 ~1.7 Gh/s. ASIC miners deliver far higher hash rates: the Antminer KS3 at 8 Th/s produces roughly 5,000× the output of a single RTX 3080.
What algorithm does Kaspa use?
KHeavyHash — a modified version of the HeavyHash algorithm optimized to be memory-hard and GPU-mineable.
Best GPU for mining Kaspa?
The RTX 4090 leads with ~3.8 Gh/s. The RTX 3080 (~1.7 Gh/s) and RTX 3090 (~2.1 Gh/s) are solid choices at lower upfront cost.
Is Kaspa ASIC-mineable?
Yes. Purpose-built Kaspa ASICs (Antminer KS3, Goldshell KD6) are now available and dominate the network. GPU mining Kaspa is still possible but ASICs have a large efficiency advantage.
