ASIC miners · Blake2B-SHA3
Handshake miners (Blake2B+SHA3)
ASIC miners for Handshake (HNS), Blake2B+SHA3 algorithm – for example the Goldshell HS Box II. For every machine you can see its hashrate, power draw and returns in CZK, recalculated for today's network difficulty and exchange rate.
Handshake is a decentralised domain name system (an alternative to the DNS root zone); a new block is produced roughly every 10 minutes. The coin has low liquidity – before you buy, feel free to ask us about machine availability and returns after electricity costs.

How to choose a Handshake miner
First decide where the machine will run – that determines the cooling. For each type we show the machines from this collection that earn the most today from 1 kWh of electricity.
-
hosting, workshop
Air-cooled
The most common and cheapest option: fans cool the machine, so it only needs a supply of cool air and a way to remove the heat. It is loud, though (usually 70–80 dB), so it does not belong in a flat – it suits our hosting, a workshop or a plant room, and at home only with a soundproof box.

How hosting works -
quieter, heat for heating
Hydro (water cooling)
A liquid in a closed loop cools the chips and a dry cooler or heat exchanger removes the heat. Hydro machines are quieter and more powerful, but they need a water loop and usually a three-phase supply. You can use the heat to warm water or for heating.
There are none in this collection right now. Write to us – we will check availability.
Water loops for Hydro -
farms, almost silent
Immersion cooling
The machine is submerged in dielectric fluid in an immersion tank – it is almost silent and the chips stay at an even temperature. It needs a tank, a pump and a cooler, so it is best suited to farms and hosting.

Handshake miner comparison
Sorted from the most efficient – fewest joules per unit of hashrate. We recalculate revenue every hour, and profit using the electricity price selected above the miners: on hosting at 1.14 Kč/kWh.
| Model | Hashrate | Power | Efficiency | Cooling | Noise | Price from | Revenue / day | Profit / day |
|---|---|---|---|---|---|---|---|---|
| Goldshell HS Box II | 460 GH/s | 400 W | 0.87 J/GH | Air | 35 dB | from 27 554 Kč | 4.32 Kč | −6.62 Kč |
Hashrate, power draw and noise are stated by the manufacturers. Efficiency = power draw ÷ hashrate. Revenue = hashrate × today’s revenue of the algorithm’s most profitable coin (before electricity and pool fees); profit = revenue − electricity at the selected price. For machines with several hashrate options we use the base hashrate from the product card.
At home or on our hosting?
The result of mining depends mainly on the electricity price. Comparison for the machine in this collection that earns the most per 1 kWh – Goldshell HS Box II.
At home or at your business
- Grid electricity costs a Czech household roughly 4.5–6.5 Kč/kWh (2026); it is cheaper from your own solar panels or on a business tariff.
- A powerful ASIC needs its own circuit and ventilation, and you have to expect noise – air-cooled machines are usually 70–80 dB.
- You can use the miner’s heat for heating, but in summer you have to get rid of it.
Profit at 4.5 Kč/kWh: −38.88 Kč / day
On our hosting
- Electricity from 1.14 Kč/kWh including management (Nigeria #2), 7 locations with free capacity.
- With prepaid electricity, up to 30% cheaper.
- New miners bought from us that run on our hosting come with a 7-year warranty. We take care of noise, cooling and repairs.
Profit at 1.14 Kč/kWh: −6.62 Kč / day
Profit = today’s revenue − electricity for 24 hours, before pool fees. Network difficulty and the exchange rate change; this is neither a forecast nor a promise of revenue.
FAQ about Handshake miners
What is Handshake and how is it mined?
Handshake (HNS) is a decentralised system of top-level domain names – an alternative to the DNS root zone. It is mined with the Blake2B+SHA3 algorithm (a combination of the BLAKE2b and SHA-3 hash functions) on specialised ASIC miners, with a block roughly every 10 minutes.
How much does a Handshake miner earn per day?
Revenue depends on the machine's hashrate, network difficulty and the HNS exchange rate. We recalculate the current value in Kč every hour and show it on each machine's card – it is today's figure before electricity costs, not a guarantee for the future.
Can I place a Handshake miner in your hosting?
Yes, we place the machines in a data centre with cheaper electricity and take care of their operation. Prices by location are on the page Miner hosting.
