Installing the OJO node in the Sauron test network !!!

OJO is an IBC-native decentralized price oracle incubated by Umee, created for all IBC assets. It offers secure and robust interchain communication for accurate price data from various authenticated centralized and decentralized data sources.

minimum recommended hardware configuration :

4 cores (modern CPU's)
8Gb of
RAM200Gb of disk space
10Mbps permanent internet connection

updating the server:

sudo apt update && sudo apt upgrade -y

install the necessary utilities:

sudo apt install curl build-essential git wget jq make gcc tmux chrony -y

specify the name of your validator, which will be visible in the explorer:

NODENAME=<NAME_VALIDATOR>

saving and importing variables :

echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
	echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export OJO_CHAIN_ID=ojo-devnet" >> $HOME/.bash_profile
source $HOME/.bash_profile

installing GO:

ver="1.19.1" && \
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" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version

clone and assemble the binary file:

cd $HOME
wget https://github.com/ojo-network/ojo/releases/download/v0.1.2/ojod-v0.1.2-linux-amd64.tar.gz
tar -xvzf ojod-v0.1.2-linux-amd64.tar.gz
sudo chmod +x ojod && sudo mv ./ojod /usr/local/bin/ojod
sudo rm -rf ojod_linux_amd64.tar.gz

initializing the application:

ojod init $NODENAME --chain-id $OJO_CHAIN_ID

download the genesis file:

curl -s https://rpc.devnet-n0.ojo-devnet.node.ojo.network/genesis | jq -r .result.genesis > $HOME/.ojo/config/genesis.json

adding peers:

SEEDS=""
PEERS="[email protected]:26656,[email protected]:39656,[email protected]:21656,[email protected]:12656,[email protected]:31656,[email protected]:26656,[email protected]:26656,[email protected]:50656,[email protected]:25356,[email protected]:17656"; \
sed -i.bak -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.ojo/config/config.toml

setting up pruning:

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.ojo/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.ojo/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.ojo/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.ojo/config/app.toml

we set the minimum gas price:

sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.025uojo\"/;" ~/.ojo/config/app.toml

if necessary, disable indexing (indexer = "null"):

cd ~

nano $HOME/.ojo/config/config.toml

ctrl O, enter, ctrrl X

resetting the chain data:

ojod tendermint unsafe-reset-all --home $HOME/.ojo

creating a service file:

sudo tee /etc/systemd/system/ojod.service > /dev/null <<EOF
[Unit]
Description=ojo
After=network-online.target

[Service]
User=$USER
ExecStart=/usr/local/bin/ojod start 
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

launching the service file:

sudo systemctl daemon-reload
sudo systemctl enable ojod
sudo systemctl restart ojod && sudo journalctl -u ojod -f -o cat

after the synchronization is complete, load the variables into the system:

source $HOME/.bash_profile

creating or restoring a wallet:

ojod keys add $WALLET

ojod keys add $WALLET --recover

we save the information, enter the commands in turn, enter your password in 1 and 2:

OJO_WALLET_ADDRESS=$(ojod keys show $WALLET -a)

OJO_VALOPER_ADDRESS=$(ojod keys show $WALLET --bech val -a)

echo 'export OJO_WALLET_ADDRESS='${OJO_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export OJO_VALOPER_ADDRESS='${OJO_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

creating a validator:

ojod tx staking create-validator \
  --amount 10000000uojo \
  --from $WALLET \
  --commission-max-change-rate "0.01" \
  --commission-max-rate "0.2" \
  --commission-rate "0.05" \
  --min-self-delegation "1" \
  --pubkey  $(ojod tendermint show-validator) \
  --moniker $NODENAME \
  --identity=<__> \
  --website="__" \
  --details="__" \
  --chain-id $OJO_CHAIN_ID \
  --fees=5500uojo \
  --gas=auto -y

delete node:

sudo systemctl stop ojod
sudo systemctl disable ojod
sudo rm /etc/systemd/system/ojo* -rf
sudo rm $(which ojod) -rf
sudo rm $HOME/.ojo* -rf
sudo rm $HOME/ojo -rf
sed -i '/OJO_/d' ~/.bash_profile
