Node setup for Ojo Network
Update the system and install the essentials:
$ sudo apt update && sudo apt full-upgrade -y && apt install build-essential
$ sudo apt install vim /or apt install nano
$ sudo apt install entr jq make git ufw wget
Install GO and Cosmovisor
$ sudo rm -r /usr/local/go/
$ wget https://golang.org/dl/go1.19.12.-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.19.12.-amd64.tar.gz
$ rm go1.19.12.-amd64.tar.gz
$ echo export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin >> $HOME/.bash_profile
$ source $HOME/.bash_profile
# Install cosmovisor
$ go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]
$ sudo mv /usr/local/
Clone the repository and install node binary
$ cd $HOME
$ git clone https://github.com/ojo-network/ojo.git
$ cd ojo
$ git checkout v0.1.2* always doublecheck from the official team for the right version
$ make install
Set up cosmovisor
$ mkdir -p $HOME/.ojo/cosmovisor/genesis/bin
$ mkdir -p $HOME/.ojo/cosmovisor/upgrades
$ mv $HOME/go/bin/ojod $HOME/.ojo/cosmovisor/genesis/bin/
$ sudo ln -s $HOME/.ojo/cosmovisor/genesis $HOME/.ojo/cosmovisor/current -f
$ sudo ln -s $HOME/.ojo/cosmovisor/current/bin/ojod /usr/local/bin/ojod -f

Set up node
Please when using this guide replace “YOUR_MONIKER” with name for your node.
$ ojod init YOUR_MONIKER –chain-id ojo-devnet
# Get address book and genesis.json
$ wget -O ~/.ojo/config/genesis.json https://rpc.devnet-n0.ojo-devnet.node.ojo.network/genesis
#Set minimum gas prices
sed -i -e “s|^minimum-gas-prices *=.*|minimum-gas-prices = \”0uojo\”|” $HOME/.ojo/config/app.toml
# You can get address book from any validator (you only need 1 address book)
Polkachu
$ wget -O addrbook.json https://snapshots.polkachu.com/testnet-addrbook/ojo/addrbook.json –inet4-only
mv addrbook.json ~/.ojo/config or
KJ Nodes
$ curl -Ls curl -Ls https://snapshots.kjnodes.com/ojo-testnet/addrbook.json > $HOME/.ojo/config/addrbook.json or
NodeJumper
$ curl -s https://snapshots-testnet.nodejumper.io/ojo-testnet/addrbook.json > $HOME/.ojo/config/addrbook.json
# Or find seed from some validator that offers seed to bootstrap your node.
Use state sync or snapshot to catch up
Use snapshot or state sync to catch up. * If you plan to use state sync make sure that validator that offers these services offers wasm file.

Start the node
$ sudo systemctl start ojod && sudo journalctl -fu ojod -o cat
Validator setup for Ojo Network
Create keys and validator
#Create the wallet ( replace #keyname with whatever name you want)
$ ojod keys add #keyname
#Now create the validator
