The KHeavyhash algorithm is a tailored hashing algorithm explicitly programmed for mining the cryptocurrency Kaspa (KAS). When most mining algorithms depend on GPU memory, the KHeavyhash algorithm involves matrix multiplication sandwiched between two standard Keccak hashes, which is commonly known as SHA-3.

That makes KHeavyhash computationally intensive, enabling miners to indulge in dual mining — miners can mine other cryptocurrencies that utilize memory-intensive mining algorithms alongside Kaspa.
