Bridge Node Setup for Mocha Testnet (mocha-4)

Hardware Requirements

Setting up a bridge node

Update packages and Install dependencies:

sudo apt update && sudo apt upgrade -y
sudo apt install curl git wget htop tmux build-essential jq make gcc tar clang pkg-config libssl-dev ncdu -y

Install :

cd ~
! [ -x "$(command -v go)" ] && {
VER="1.25.1"
wget "https://golang.org/dl/go$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"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source ~/.bash_profile
}
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin
go version

Install Celestia-node:

cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.28.5-mocha  
make build 
sudo make install 
make cel-key

Config and init app:

celestia bridge init --core.ip <RPC_NODE_IP> --p2p.network mocha

Once you start the Bridge Node, a wallet key will be generated for you. You will need to fund that address with Testnet tokens to pay for PayForBlob transactions. You can find the address by running the following command:

cd $HOME/celestia-node
./cel-key list --node.type bridge --keyring-backend test --p2p.network mocha

Create Service file:

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

[Service]
User=$USER
ExecStart=$(which celestia) bridge start \
--p2p.network mocha --archival \
--metrics.tls=true --metrics --metrics.endpoint otel.mocha.celestia.observer
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Enable and start service:

sudo systemctl daemon-reload
sudo systemctl enable celestia-bridge
sudo systemctl restart celestia-bridge && sudo journalctl -u celestia-bridge -fo cat

Get your node's peerId information:

❗NOTE: You can only generate an auth token after initializing and starting your celestia-node.

NODE_TYPE=bridge
AUTH_TOKEN=$(celestia $NODE_TYPE auth admin --p2p.network mocha)

Then you can get the peerId of your node with the following curl command:

curl -X POST \
     -H "Authorization: Bearer $AUTH_TOKEN" \
     -H 'Content-Type: application/json' \
     -d '{"jsonrpc":"2.0","id":0,"method":"p2p.Info","params":[]}' \
     http://localhost:26658

Cheat sheet

Check bridge wallet balance:

celestia state balance --node.store ~/.celestia-bridge-mocha-4/

Get wallet address:

cd $HOME/celestia-node
./cel-key list --node.type bridge --keyring-backend test  --p2p.network mocha

Restore an existing cel_key:

KEY_NAME="my_celes_key"
cd ~/celestia-node
./cel-key add $KEY_NAME --keyring-backend test --node.type bridge  --recover --p2p.network mocha

Check bridge node status:

celestia header sync-state --node.store  ~/.celestia-bridge-mocha-4/

Get Node ID:

celestia p2p info --node.store ~/.celestia-bridge-mocha-4/

(Optional) Add permissions for transferring keys to another server:

chmod -R 700 ~/.celestia-bridge-mocha-4

Reset node:

celestia bridge unsafe-reset-store --p2p.network mocha

Upgrade

Stop bridge node:

sudo systemctl stop celestia-bridge

Download binary:

cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.28.5-mocha  
make build 
sudo make install 
make cel-key

Update:

celestia bridge config-update --p2p.network mocha

Start bridge node:

sudo systemctl restart celestia-bridge && sudo journalctl -u celestia-bridge -fo cat

Delete bridge node

sudo systemctl stop celestia-bridge
sudo systemctl disable celestia-bridge
sudo rm /etc/systemd/system/celestia-bridge*
rm -rf $HOME/celestia-node $HOME/.celestia-bridge-mocha-4
