echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bashrc
source ~/.bashrc
mkdir -p ~/go/bin

### Config and init bridge

cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.22.3 -b v0.22.3
make build
sudo make install
make cel-key

# Config and init app:
celestia light init

# Create wallet:
KEY_NAME="my_celes_key"
cd ~/celestia-node
./cel-key add $KEY_NAME --keyring-backend test --node.type light

# (Optional) Restore an existing cel_key:
KEY_NAME="my_celes_key"
cd ~/celestia-node
./cel-key add $KEY_NAME --keyring-backend test --node.type light

# You can find the address by running the following command in the celestia-node directory:
cd $HOME/celestia-node
./cel-key list --node.type light --keyring-backend test
CORE_IP="<PUT_CONSENSUS_NODE_IP>"
CORE_RPC_PORT="<PUT_CONSENSUS_NODE_RPC_PORT>"
CORE_GRPC_PORT="<PUT_CONSENSUS_NODE_GRPC_PORT>"
KEY_NAME="my_celes_key"
