kHeavyHash

kHeavyHash is the mining algorithm used by Kaspa, a cryptocurrency launched at the end of 2021. It is a variant of HeavyHash: it combines a hash function from the Keccak family, the one that gave rise to SHA-3, with a matrix multiplication. Like any proof of work, it demands a large amount of computation from miners, while verifying a block remains very fast for the network.

Kaspa stands out for its blockDAG structure, called GHOSTDAG: several blocks can be created in parallel without being rejected, which allows blocks to be produced far more often than on Bitcoin, which adds one roughly every ten minutes. For miners, this means a very steady flow of blocks. Kaspa was first mined on graphics cards, before ASICs took over from 2023 onwards.

The hashrate of kHeavyHash miners is expressed in GH/s or TH/s. The best-known ranges are the IceRiver KS, the Antminer KS and some Goldshell models. As always, compare efficiency in J/TH rather than hashrate alone, and check the noise level: some compact models are designed for the home, others for a hosting site.

Our Kaspa collection brings together the kHeavyHash miners we offer.
