PostHuman Celestia Bridge Node Setup Guide

This guide will help you set up a Celestia bridge node using PostHuman infrastructure.

---

Hardware Requirements

| Node Type | Memory | Disk | |---------------------|-------------|------------| | Light node | 500 MB RAM | 100 GB SSD | | Bridge node | 64 GB RAM | 5 TiB NVME | | Full storage node | 64 GB RAM | 5 TiB NVME |

---

1. 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

---

2. Install Go

cd ~
! [ -x "$(command -v go)" ] && {
  VER="1.22.6"
  wget "https://golang.org/dl/go$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

---

3. Install Celestia Node

cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.21.5
make build
sudo make install
make cel-key

---

4. Configure and Initialize the Bridge Node

celestia bridge init --core.ip https://rpc.celestia-mainnet.posthuman.digital

After starting the Bridge Node, a wallet key will be generated. You need to fund this address with Mainnet tokens for PayForBlob transactions. Retrieve your wallet address using:

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

---

5. Create a Service File for Celestia Bridge

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 --archival \
--metrics.tls=true --metrics --metrics.endpoint otel.celestia.observer
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Enable and start the service:

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

---

6. Retrieve Node Information

After initializing and starting your node, generate an auth token:

NODE_TYPE=bridge
AUTH_TOKEN=$(celestia $NODE_TYPE auth admin)

Then, get the peer ID:

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

---

7. Download and Restore Bridge Node Snapshot

Installing dependencies:

sudo apt install aria2 jq lz4 unzip -y

Downloading and unpacking the snapshot:

cd $HOME
aria2c -x 16 -s 16 -o celestia-bridge-snap.tar.lz4 https://server-9.itrocket.net/mainnet/celestia/bridge/null
sudo systemctl stop celestia-bridge
rm -rf ~/.celestia-bridge/{blocks,data,index,inverted_index,transients,.lock}
tar -I lz4 -xvf ~/celestia-bridge-snap.tar.lz4 -C ~/.celestia-bridge/
sudo systemctl restart celestia-bridge && sudo journalctl -u celestia-bridge -fo cat

Removing the snapshot file:

rm ~/celestia-bridge-snap.tar.lz4

---

8. Useful Commands (Cheat Sheet)

Check Wallet Balance

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

Get Wallet Address

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

Restore an Existing Key

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

Check Node Sync Status

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

Get Node ID

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

Add Permissions for Key Transfers

chmod -R 700 ~/.celestia-bridge

Reset Node

celestia bridge unsafe-reset-store

---

9. Upgrade Instructions

Stop Bridge Node

sudo systemctl stop celestia-bridge

Download Latest Version

cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
git checkout tags/v0.21.5
make build
sudo make install
make cel-key

Update Configuration

celestia bridge config-update

Restart Bridge Node

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

---

10. 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
