Came Across 1st Grin ASIC of the World

Mining
24

Finally, I borrowed one G1 miner a few days ago and tried it by myself, so I can share some updated info here :slight_smile: (Thanks Thomas to borrow this miner to me for a test!)

Took two shots on this G1 miner ~

The box dimension is about 44cm x 20cm x 35cm, it looks like a desktop computer. The box weight is about 20kg, including that attached power adapter. 4 big strong fans, 2 on each sides. The box is quite solid.

I connected this miner to a grin node to try mining, after less 24 hours, I got 3 blocks (819660, 820461, 820801) mined :grin:

BTW, I tested it at my home, the big noise of the fan is a little bit annoying for the family, I have to limit the maximum fan speed to 30% for this test. I suppose the miner performance will be much better if let its fan work at maximum 100%.

For thanks and fun to read this post, I would like to share above mined 3 blocks award to people who request to be shared here :slight_smile: Please just leave here your wallet receiving address, I will send 10 GRINs for each request, until the total 180 GRINs has been completely sent out. (only one request per one forum user of course.)

( :sunny:Tip: About the detail info of this G1 miner, if interested, you can ask the manufacturer directly on next Grin governance meeting on Tuesday Aug 11 @ 15:00 UTC in Keybase main lobby, Thomas from Vidtoo & MicroComputer will join that meeting for some Q&A. Refer to the news here).
