GRIMM Solo Mining Guide

  • Adapted from Raskul's guide
  • With help from Freshminer and Mikeyb

Installation

  • From Releases download the following
    • grimm-wallet-cli
    • grimm-node
  • Extract downloads into a folder called grimm-mining

Setup

  • Create SSL certificate & key in grimm-mining directory
    • `openssl req -newkey rsa:4096 -nodes -keyout stratum.key -x509 -days 365 -out stratum.crt
  • Create a file called stratum.api.keys and add a alphanumeric string
    • Example: Zmohq90bfgMvLB4gjL9NS5PeAJ7CReXO3G7aZ0aW
    • You can add 1 string per line. These are used at the user in your mining client
  • Edit grimm-wallet.cfg file removing the # before pass and node_addr
    • pass=abcdefghijklmnopqrstuvwxyz1234567890
    • node_addr=127.0.0.1:10005
    • Leave the rest as is
  • Initialize wallet by running this command in a terminal
    • ./grimm-wallet init
    • Save the passphrase and address before continuing
  • Export miner key by running this command in a terminal
    • ./grimm-wallet export_miner_key --subkey=1
    • Take the key and put in the grimm-node.cfg file on the key_mine= line
  • Export owner key by running this command in a terminal
    • ./grimm-wallet export_owner_key
    • Take the key and put in the grimm-node.cfg file on the key_owner= line
  • Get the pass in grimm-wallet.cfg and add it to the pass= line in grimm-node.cfg
  • Add these entries to grimm-node.cfg
    • port=10005
    • log_level=verbose
    • file_log_level=verbose
    • mining_threads=0
    • peer=67.205.185.92:8385,165.22.197.90:8385,134.209.157.140:8385,104.248.242.82:8385
    • stratum_port=3333
      • Make sure your firewall is allowing connections to this port if mining externally
    • stratum_secrets_path=.
  • Start the node with the following command
    • ./grimm-node
    • Leave this terminal open to keep the node running
  • Wait for node to fully synchronize
  • Open another terminal window in grimm-mining directory and run the command
    • ./grimm-wallet listen
    • Leave this terminal open to keep the wallet listening
  • Point your miner at the ip address and port of this device with key from stratum.api.keys instead wallet address
