Chia official protocol multi-machine cluster mining detailed tutorial

Use a computer as a Farmer, synchronize the node, create NFT and connect to the official mining pool.

Refer to the Chia official mining pool protocol mining tutorial .

The Harvester computer does not need to synchronize nodes and wallets. There is no official graphical interface program to run Harvester separately, and it can only be started through the command line.

 .\chia.exe init -c C:\farmer-ca\ca 

Modify the harvester configuration file

The path of the configuration file is C:\Users\ xx \.chia\mainnet\config\config.yaml ( xx is your computer user name ) . Use Notepad to open the file ( right click -> Open with -> More Applications -> Notepad ) and find the harvester configuration, as shown below.
