kHeavyHash

Kaspa's proof-of-work algorithm — lightweight, energy-efficient, and ASIC-mined since 2023 with the fastest hardware iteration cycle in the industry.

kHeavyHash combines Keccak hashing with a matrix multiplication step. It launched GPU-minable, but Kaspa's price surge triggered the fastest ASIC transition ever seen: from IceRiver's first units in 2023 to Bitmain's KS7 (70 TH/s) in 2025, hashrate grew thousands-fold and GPUs were obsoleted within months.

Kaspa's blockDAG architecture produces multiple blocks per second, giving miners smooth, low-variance rewards. The lesson of kHeavyHash for miners: on any rising coin, model ASIC arrival risk before buying previous-generation hardware.
