Guide
Here is a node installation guide (Simplified and manual)
Preparing the server for installation
sudo apt update && sudo apt upgrade -y
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc git jq chrony liblz4-tool -y
Installing the latest version of Go
ver="1.21.1"
cd $HOME
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
source ~/.bash_profile
Build
cd ~
git clone https://github.com/desmos-labs/desmos.git
cd desmos
git checkout v6.2.1
make install
Init your node
desmos init <YOUR_MONIKER> --chain-id desmos-mainnet
desmos config chain-id desmos-mainnet
Create or recover your wallet
#NEW WALLET
desmos keys add <WALLET_NAME>
#RECOVER OLD WALLET
desmos keys add <WALLET_NAME> --recover
Download Genesis
curl https://raw.githubusercontent.com/desmos-labs/mainnet/main/genesis.json > ~/.desmos/config/genesis.json
Set up the minimum gas price and Peers/Seeds/Filter peers/MaxPeers
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.01udsm\"/;" ~/.desmos/config/app.toml
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.desmos/config/config.toml
Download addrbook
wget -O $HOME/.desmos/config/addrbook.json "https://raw.githubusercontent.com/nodersteam/cosmos-adrbook/main/desmos/addrbook.json"
To connect the node to monitoring (optional), enable prometheus activation
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.desmos/config/config.toml
Create a service file
sudo tee /etc/systemd/system/desmos.service > /dev/null <<EOF

Use our StateSync

BLOCK_HEIGHT=$((LATEST_HEIGHT - 500)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

Start your node
sudo systemctl daemon-reload && sudo systemctl enable desmos
sudo systemctl restart desmos && sudo journalctl -u desmos -f -o cat
Buy some tokens on OSMOSIS
Wait for full synchronization and create a validator
desmos tx staking create-validator \
--amount=1000000udsm \
--pubkey=$(desmos tendermint show-validator) \
--moniker="<YOUR_MONIKER>" \
--chain-id=desmos-mainnet \
--commission-rate="0.10" \
--commission-max-rate="0.20" \
--commission-max-change-rate="0.01" \
--min-self-delegation="1" \
--gas="auto" \
--gas-adjustment=1.2 \
--gas-prices="0.025udsm" \
--from=<WALLET_NAME> -y
If you want to delete a node
sudo systemctl stop desmos && \
sudo systemctl disable desmos && \
rm /etc/systemd/system/desmos.service && \
sudo systemctl daemon-reload && \
cd $HOME && \
rm -rf .desmos && \
rm -rf desmos && \
rm -rf $(which desmos)
