Gary, the former core developer of the privacy project Grin, recently stated on the forum that he borrowed a Grin Asic mining machine and conducted a running test. 3 blocks were mined in less than 24 hours.

Gary described the appearance of the miner. Similar to other Asic miners, the size of the Grin miner is approximately 44cm x 20cm x 35cm, and the box weight is approximately 20 kilograms. Gary
Connected the miner to a grin node and tried mining. In less than 24 hours, he mined 3 blocks (819660.820461.820801), with a total block reward of
180 Grin. However, Gary said that because the cooling fan is not adjusted to the maximum in order to control noise when mining at home, the mining efficiency of the mining machine may be higher.

From the data point of view, this ASIC mining machine supports the C31 and C32 algorithms (in the hard fork upgrade in July, the Grin 29 algorithm was upgraded from Cuckaroom to
Cuckarooz). The current computing power of the algorithm Cuckatoo32 (AT32) is 14833 Gps, and the computing power of the Cuckaroo29 (AR29) algorithm is 7545
