Ojo - Oracle Network - Testnet

Ojo is a decentralized security-first oracle network built to securly support ecosystem-native assets. Ojo sources price data from a diverse catalog of on and off-chain sources and use advanced security mechanisms to guarantee the integrity of the data it provides. The advantages of this network are: accessible, reliable and trust-less.

It is compatible with any chain IBC enabled chain and EVMs. Ojo collects data from on-chain and off-chain reliable sources and all validators vote on vote on the prices used in Ojo’s price feeds making sure prices are reliable.

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

$ 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
