Chia Notes

Installing

Install packages

$ sudo apt-get update
$ sudo apt-get install ca-certificates curl gnupg

Add GPG key

$ curl -sL https://repo.chia.net/FD39E6D3.pubkey.asc | sudo gpg --dearmor -o /usr/share/keyrings/chia.gpg

Set up repository

$ echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/chia.gpg] https://repo.chia.net/debian/ stable main" | sudo tee /etc/apt/sources.list.d/chia.list > /dev/null
$ sudo apt-get update

Install chia-blockchain

$ sudo apt-get install chia-blockchain

Open port

On your farmer, get your IP address:

$ ip a

On your internet router, setup port forwarding for 8444 ->

On your farmer, open the port in your firewall:

$ sudo ufw allow 8444/tcp

Use an online port checking website to verify that your 8444 port is open.

Mounting Hard Drives

You can list available local hard drives to mount with:

$ lsblk

You need to make sure you have mount directories for the drives:

$ mkdir /mnt/hdd
$ mkdir /mnt/hdd2
$ mkdir /mnt/ssd
$ mkdir /mnt/ssd2
$ mkdir /mnt/chchchia-volume1
$ mkdir /mnt/chchchia-volume2
$ mkdir /mnt/chchchia-volume3
$ mkdir /mnt/chchchia-volume4
$ mkdir /mnt/chchchia-volume5

Then you can mount the drives:

# Internal drives
$ sudo mount /dev/sdb /mnt/hdd
$ sudo mount /dev/sdd /mnt/hdd2

# SSDs for plotting
$ sudo mount -t xfs -o discard /dev/sda /mnt/ssd
$ sudo mount -t xfs -o discard /dev/sdc /mnt/ssd2

# External drives
$ sudo mount -t nfs 169.254.250.65:/volume1/volume1shared /mnt/chchchchia-volume1
$ sudo mount -t nfs 169.254.250.65:/volume2/volume2shared /mnt/chchchchia-volume2
$ sudo mount -t nfs 169.254.250.65:/volume3/volume3shared /mnt/chchchchia-volume3
$ sudo mount -t nfs 169.254.250.65:/volume4/volume4shared /mnt/chchchchia-volume4
$ sudo mount -t nfs 169.254.250.65:/volume5/volume5shared /mnt/chchchchia-volume5

  • chia start farmer -r – Restarts everything
  • chia init – Migrates files from an old version to the latest version after an update
  • chia start node – Starts node only
  • chia start node -r – Restarts the node
  • chia plots check – Checks all plot files
  • chia show -s – Show status of node
  • chia show -c – Show connections
  • chia farm summary – Show summary of the farmer

Read Logs

$ tail -f -n 5000 ~/.chia/mainnet/log/debug.log

Plotting

You can figure out how many cores your machine has with:

$ lscpu

Getting info about the madmax plotter:

$ chia plotters madmax -h

Get the farmer key with:

$ chia keys show
# Farmer: b4037a7138d5757e62c4494bce69199faf7a9cd79aa71c+++++++++++++++++++++++++++

Get the pool contract address:

$ chia plotnft show
# Pool contract: xch1sff6x4292lh6l4mxx7s4egz7vt8++++++++++++++++++++

You can get information about the hard drives on your machine:

$ sudo lshw -class disk -class storage
# tmpdir = /mnt/ssd
# final dir = /mnt/hdd

Plotting with madmax:

  • -k = size
  • -r = threads (1 per core)
  • -n = number of plots
  • -t = tmp directory
  • -d = final directory
  • -f = farmer key
  • -c = contract address
$ chia plotters madmax -k 32 -r 24 -n 1 -t /mnt/ssd -d /mnt/hdd -f <farmer-key> -c <contract-address>
