Mining Grin (Grin)
Currently bminer only supports the Cuckaroo29 algorithm. There are a few things that need to be customized for your own usages:
bminergrinwith your own GRIN address.
workerto your worker name.
footo your password.
Currently bminer only supports the Cuckaroo29 algorithm. For example:
bminer -uri cuckaroo29://bminergrin.worker:email@example.com:8898
Grin Mining Tutorial

Bminer Grin mining on Sparkpool
Note: you are able to set the worker name on spark pool if you follow the tutorial.
Bminer Grin mining on Grinmint pool
Note: you are able to set the worker name on Grinmint pool if you follow the tutorial.
How to tweaking the CPU usage for mining AE / Grin with the
Both Aeternity / Grin requires significant CPU power to aid the mining. You might have sub-optimal performance if the machine is running on a low-end CPU (e.g. Intel Celeron) with multiple GPUs. Optionally, you can experiment the CPU usage with the
bminer -uri cuckaroo29://bminergrin.worker:firstname.lastname@example.org:13654 -intensity 6
The intensity is between 0 and 12. Lower intensity has lower CPU usage but potentially slower on mining.
Sample Usage of mining grin over nicehash:
bminer -uri cuckaroo29://1DQ4bZpFTDiSNk2CWLEFWK9K96rBFP2Hv@grincuckaroo29.usa.nicehash.com:3371
bminer -uri cuckatoo31://1DQ4bZpFTDiSNk2CWLEFWK9K96rBFP2Hv@grincuckatoo31.usa.nicehash.com:3372
Specifying AMD devices¶
You can specify which cards that Bminer should mine on using the
-devices options. While Bminer runs on the NVIDIA cards by default, you can prefix the device IDs with
amd: to run on AMD cards. For example:
bminer -devices amd:0 -uri beam+ssl://email@example.com:2222
Bminer will run on the first AMD card on the system.
