lumd version

$ lumd version --long
name: lum
server_name: lumd
version: 1.0.4
commit: e3068181b029af45bcbbe4678804b776eef6087b

Installation

Prerequisites: Make sure to have Golang >=1.17.

Make sure your Go configuration looks like that one (especially the GO111Module):

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin

Clone the repository

git clone https://github.com/lum-network/chain.git
cd chain
git checkout v1.0.4
make install

Check that you have the right lumd version installed:

lumd version --long

name: lum
server_name: lumd
version: 1.0.4
commit: e3068181b029af45bcbbe4678804b776eef6087b

Setup your node

Download Genesis file.

curl -s  https://raw.githubusercontent.com/lum-network/mainnet/master/genesis.json > ~/.lumd/config/genesis.json

sha256sum ~/.lumd/config/genesis.json
3bbbd7aff6c545126d869fc683f6344e65ae71b048b25540826cd2f3be91a24c

Add seed peers and persistent peers to your config.toml

nano ~/.lumd/config/config.toml

Create a systemd file for your Lum Network service:

sudo nano /etc/systemd/system/lumd.service

Copy and paste the following and update <YOUR_HOME_PATH>:

[Unit]
Description=Lum Network daemon
After=network-online.target

[Service]
User=lum
ExecStart=/<YOUR_HOME_PATH>/go/bin/lumd start --p2p.laddr tcp://0.0.0.0:26656 --home /<YOUR_HOME_PATH>/.lumd
Restart=on-failure
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

2 This assumes $HOME/go to be your Go workspace, and $HOME/.lumd to be your directory for config and data. Your actual directory locations may vary.

Enable and start the new service:

sudo systemctl enable lumd
sudo systemctl start lumd

Check status:

lumd status

Check logs:

journalctl -u lumd -f

Validator setup

1. Minimum hardware requirements

4 CPU ores
16 GB RAM
200 GB of disk space
100 mbps bandwidth

2. Configure minimum gas price

Configure the minimum gas price to minimum-gas-prices = "0.001ulum"

nano ~/.lumd/config/app.toml

3. Create validator transaction

Set the parameters you want

lumd tx staking create-validator \
  --amount=1000000ulum \
  --pubkey=$(lumd tendermint show-validator) \
  --moniker="my super new validator" \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1" \
  --chain-id=lum-network-1

You can also edit your validator afterward

lumd tx staking edit-validator \
   --website="https://lum.network" \
   --details="So luminous" \
   --chain-id=lum-network-1 \

4. Upload validator logo

If you want your validator to have a logo displayed on the Lum Network explorer, you must follow the procedure detailed here: https://github.com/lum-network/public-assets

If you want to do the same for Mintscan, you must follow the similar procedure detailed here: https://github.com/cosmostation/cosmostation_token_resource

5. Join Discord

Once your validator is up and running you can join the private validator channel on Discord.

This is the main communication channel with validators.

Join the Lum Network Discord server
Ping the infrastructure-support channel to get the Validator Role and access the validator channels
