what is the requirement to mine the mass?
For the test network, During the Testnet, users need to have a computer connected to the internet, a storage medium (e.g. a hard drive), the full-node client for MASS, and Full Node Client for Testnet running on, and a 64-bit Linux or macOS operating system that is capable of running the MASS full-node client. Other than these, there are no other specific requirements besides. For a more detailed guide, please refer to the MASS project documentation.
For the main network, follow the instructions in the MASS full node client and the full node wallet configuration manual.
