Installation

If you want to setup Ojo fullnode manually follow the steps below

Update and upgrade

sudo apt update && sudo apt upgrade -y

Install GO

if ! [ -x "$(command -v go)" ]; then
  ver="1.19.3"
  cd $HOME
  wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"

  source ~/.bash_profile
fi

Install node

cd $HOME
git clone https://github.com/ojo-network/ojo.git
cd ojo
git checkout v0.1.2
make install

Setting up vars

You should replace values in <> <YOUR_MONIKER> Here you should put name of your moniker (validator) that will be visible in explorer <YOUR_WALLET> Here you shoud put the name of your wallet

echo "export OJO_WALLET="<YOUR_WALLET_NAME>"" >> $HOME/.bash_profile
echo "export OJO_NODENAME="<YOUR_MONIKER>"" >> $HOME/.bash_profile
echo "export OJO_CHAIN_ID="ojo-devnet"" >> $HOME/.bash_profile
source $HOME/.bash_profile

Configure your node

ojod config chain-id $OJO_CHAIN_ID

Initialize your node

ojod init $OJO_NODENAME --chain-id $OJO_CHAIN_ID

Download genesis

wget "$HOME/.ojo/config/genesis.json" https://raw.githubusercontent.com/L0vd/chain-services/main/testnets/ojo/installation-guide/genesis.json

(OPTIONAL) Set custom ports

If you want to use non-default ports

OJO_PORT=<SET_CUSTOM_PORT> #Example: OJO_PORT=56 (numbers from 1 to 64)

sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${OJO_PORT}658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${OJO_PORT}657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${OJO_PORT}060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${OJO_PORT}656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${OJO_PORT}660\"%" $HOME/.ojo/config/config.toml
sed -i.bak -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:${OJO_PORT}317\"%; s%^address = \":8080\"%address = \":${OJO_PORT}080\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:${OJO_PORT}090\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:${OJO_PORT}091\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:${OJO_PORT}545\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:${OJO_PORT}546\"%" $HOME/.ojo/config/app.toml

Set seeds and peers

SEEDS=""
PEERS="[email protected]:36656,[email protected]:56656,[email protected]:26656,[email protected]:18656,[email protected]:50656,[email protected]:50656,[email protected]:28656,[email protected]:24656,[email protected]:36656,[email protected]:26656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.ojo/config/config.toml

Config pruning

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="50"
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

Set minimum gas price and null indexer

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0uojo\"/" $HOME/.ojo/config/app.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.ojo/config/config.toml

Create Service

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

[Service]
User=$USER
ExecStart=$(which ojod) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Reset blockchain info and restart your node

sudo systemctl daemon-reload
sudo systemctl enable ojod
ojod tendermint unsafe-reset-all --home $HOME/.ojo --keep-addr-book
sudo systemctl restart ojod && sudo journalctl -u ojod -f -o cat

(OPTIONAL) Use State Sync

State Sync

Starting a validator

1. Add a new key

ojod keys add $OJO_WALLET

(OR)

1. Recover your key

ojod keys add $OJO_WALLET --recover

2. Request tokens from faucet

3. Create validator

Wait until the node is synchronized.

ojod tx staking create-validator \
--amount 1000000uojo \
--commission-max-change-rate "0.01" \
--commission-max-rate "0.20" \
--commission-rate "0.1" \
--min-self-delegation "1" \
--details "" \
--pubkey=$(ojod tendermint show-validator) \
--moniker $OJO_NODENAME \
--chain-id $OJO_CHAIN_ID \
--from $OJO_WALLET \
--gas-prices 0.1uojo \
--gas-adjustment 1.5 \
--gas auto \
--yes

4. Price-feeder setup

Not running a price-feeder would result in being jailed! To run price-feeder you must be in active set.

Install price-feeder binary

cd $HOME
git clone https://github.com/ojo-network/price-feeder
cd price-feeder
git checkout v0.1.1
make install

Add wallet for price-feeder

ojod keys add pfd_wallet --keyring-backend os

You must fund this wallet with some uojo tokens.

Set up password for price-feeder

OJO_PFD_PASS="<INSERT YOUR PASSWORD FROM pfd_wallet YOU CREATED IN PREVIOUS STEP>"

Set up variables

echo "export OJO_VALIDATOR_ADDRESS=$(ojod keys show $OJO_WALLET --bech val -a)" >> $HOME/.bash_profile
echo "export OJO_MAIN_WALLET_ADDRESS=$(ojod keys show $OJO_WALLET -a)" >> $HOME/.bash_profile
echo "export OJO_PFD_ADDRESS=$(ojod keys show pfd_wallet -a)" >> $HOME/.bash_profile
echo "export OJO_RPC_PORT=${OJO_PORT}657" >> $HOME/.bash_profile
echo "export OJO_GRPC_PORT=${OJO_PORT}090" >> $HOME/.bash_profile
echo "export OJO_PFD_LISTEN_PORT=7172" >> $HOME/.bash_profile
echo "export OJO_KEYRING="os"" >> $HOME/.bash_profile
source $HOME/.bash_profile

Remove data from price-feeder dir and move price-feeder config

rm $HOME/.ojo-price-feeder -rf
mkdir $HOME/.ojo-price-feeder_config
mv $HOME/price-feeder/price-feeder.example.toml $HOME/.ojo-price-feeder-config/config.toml

Set values in price-feeder config.toml

sed -i "s/^address *=.*/address = \"$OJO_PFD_ADDRESS\"/;\
s/^chain_id *=.*/chain_id = \"$OJO_CHAIN_ID\"/;\
s/^validator *=.*/validator = \"$OJO_VALIDATOR_ADDRESS\"/;\
s/^backend *=.*/backend = \"$OJO_KEYRING\"/;\
s|^dir *=.*|dir = \"$HOME/.ojo\"|;\
s|^pass *=.*|pass = \"$OJO_PFD_PASS\"|;\
s|^grpc_endpoint *=.*|grpc_endpoint = \"localhost:${OJO_GRPC_PORT}\"|;\
s|^service-name *=.*|service-name = \"ojo-price-feeder\"|;" $HOME/.ojo-price-feeder-config/config.toml

Delegate price-feeder rights to pfd_wallet

ojod tx oracle delegate-feed-consent $OJO_MAIN_WALLET_ADDRESS $OJO_PFD_ADDRESS --from $OJO_WALLET --gas-adjustment 1.5 --gas auto --gas-prices 0.1uojo --yes

Create Service File for ojo-price-feeder

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

[Service]
User=$USER
ExecStart=$(which price-feeder) $HOME/.ojo-price-feeder-config/config.toml
Restart=on-failure
RestartSec=30
LimitNOFILE=65535
Environment="PRICE_FEEDER_PASS=$OJO_PFD_PASS"

[Install]
WantedBy=multi-user.target
EOF

Enable and start price-feeder service

sudo systemctl daemon-reload
sudo systemctl enable ojo-price-feeder
sudo systemctl restart ojo-price-feeder

Check price-feeder logs to make sure it's operating

sudo journalctl -u ojo-price-feeder -f
