Why Mine Kaspa with the Antminer KS3?
Kaspa (KAS) is gaining momentum as one of the most innovative layer-one blockchains, leveraging a unique blockDAG (Directed Acyclic Graph) structure to achieve fast finality and high throughput. As network difficulty increases, efficient hardware becomes essential—and that’s where the KS3 shines.
With a best-in-class power efficiency rating of 0.37 joules per terahash, the KS3 outperforms many competitors in energy usage per unit of hash power. This directly translates into lower electricity costs and higher net profits, especially in regions where power rates are moderate to high.
Additionally, the miner's compact footprint (430 x 195 x 290 mm without packaging) makes it ideal for space-constrained environments. Despite its size, it maintains excellent thermal management thanks to dual high-performance fans and optimized airflow design.
