Bitmain's first Kadena machine, running Blake2S at 166 TH/s for 3154W, an efficiency of 19 J/TH. Kadena is a braided proof-of-work chain, and the KA3 was the hardware that moved mining on it from GPUs to serious ASIC capacity. On paper 19 J/TH looks excellent, but Blake2S joules per terahash are not comparable to SHA-256 joules per terahash, so do not read this as flagship Bitcoin miner territory. Air cooling with four fans, a wide input voltage range, and a 3154W draw that needs a properly rated circuit. The current price reflects where KDA sits rather than any problem with the hardware. Reasonable if you want cheap terahash on a less crowded algorithm and are content to hold KDA, less sensible if you need predictable revenue.

Preferred over more expensive options
I actually prefer my Antminer KA3 over more expensive options I've tried. Better value, similar performance, and MinerHaolan's support is superior.
Flawless international shipping
Was worried about importing but MinerHaolan handled everything perfectly. Antminer KA3 arrived in pristine condition via DHL in just 5 days. Customs documentation was complete. Will definitely order again.
Scaled from 1 to 3 containers in a year
Started with one Antminer KA3 last year and we're now running three. The modularity is the real selling point — each container is its own self-contained data center. Our total hash rate tripled without any of the headaches of traditional facility expansion.
Expandable without redesigning anything
We started with half the racks populated in our Antminer KA3 and have been adding miners as budget allows. The infrastructure supports full capacity from day one so expansion is just slot-in-and-go. No rewiring, no cooling upgrades needed. Thoughtful planning.
Remarkably cool operation
The Antminer KA3 runs remarkably cool despite its hash rate. The thermal efficiency is impressive and it keeps my mining room at manageable temperatures. Great engineering.
