Frequently Asked
Questions
Will I actually find a block?
Statistically, it's extremely unlikely. At ~140 KH/s, the odds are astronomical. But solo miners have won before.
How long does the battery last?
Early testing showed around 4 hours of continuous mining before any optimization. We've since added smart power management: the screen dims after 30 seconds and turns off after 2 minutes. This should extend battery life significantly. We'll publish final numbers before shipping. And of course, it mines indefinitely while charging via USB-C.
How much data does it use?
Very little. The watch sends small data packets to the mining endpoint - roughly 10-20 MB per day. Easy to run off your phone's hotspot.
Can I change the mining pool?
Yes. By default it connects to public-pool.io for solo mining, but you can configure any compatible pool through the device settings. The firmware is open source, so advanced users can customize it however they like.
