Using prebuilt binary

Download chain spec and node binary

user@host:~$ mkdir -p liberland/
user@host:~$ cd liberland/
user@host:~/liberland$ wget https://github.com/liberland/liberland_substrate/releases/download/v8.1.0/linux_x86_build -O node
user@host:~/liberland$ wget https://github.com/liberland/liberland_substrate/releases/download/v8.1.0/mainnet.raw.json
user@host:~/liberland$ wget https://github.com/liberland/liberland_substrate/releases/download/v6.0.0/bastiat.raw.json
user@host:~/liberland$ chmod +x node

After downloading verify files integrity. Checksums should match with this output:

user@host:~/liberland$ sha256sum node mainnet.raw.json bastiat.raw.json 
1331ca6064b41faad7d245e7fed434d54110f5d54b58763434fb53246e09f45b  node
dbf1e9cbba193c6e6096b21c3b865ed82b3de6fca2643cf93141ac891a13ead7  mainnet.raw.json
645df3a7c84ed64e3162cc7155624268fcb09a6dcde12b88bb8db8b2bfeec882  bastiat.raw.json

If not, abort and contact dev team.

Run node

Make sure you replace DATA_DIR with a path to directory that can store at least a few gigabytes of data. Replace NETWORK with mainnet or bastiat depending on your needs.

user@host:~/liberland$ ./node \
    --chain NETWORK.raw.json \
    --validator \
    -d DATA_DIR

Note:

  • DO NOT expose your validators RPC ports (9933 and 9944 by default) publicly on the internet. Treat validators with more care than full nodes.
  • You do not need to a run a validator to earn LLD staking rewards. As a user you can simply become a nominator and stake your coins without needing to run a validator.

Optional: making it a system service

To save the trouble of debugging the process, make sure that the following command that you are passing to it will work. Use absolute path to your node binary.

/home/user/liberland/node --chain bastiat.raw.json -d /data/liberland_node --validator

After verifying that your node works, it is recommended to do this step as a system process. On ubuntu, it would look something like:

sudo systemctl edit --force --full liberland_validator.service

Then edit the file created, it should look similar to this example. Make sure:

  • insert the correct path to liberland node on your machine (the /home/user/liberland in example), both in ExecStart and WorkingDirectory
  • if setting up mainnet validator, replace bastiat.raw.json with mainnet.raw.json
  • replace /data/liberland_node with path to directory that exists and can store few gigabytes of data.
[Unit]
Description=Liberland Validator

[Service]
ExecStart=/home/user/liberland/node --chain bastiat.raw.json -d /data/liberland_node --validator
Restart=always
RestartSec=120
WorkingDirectory=/home/user/liberland

[Install]
WantedBy=multi-user.target

Save the file and then:

sudo systemctl enable liberland_validator.service
sudo systemctl start liberland_validator.service

and verify it works with

sudo systemctl status liberland_validator.service
