4️⃣GCP - Google Cloud

Run a Webhash Node on GCP to contribute to the decentralized web while benefiting from scalable infrastructure and earning token incentives for uptime and storage.

✅ Prerequisites

Make sure you have:

  • GCP account with billing enabled

  • Instance type: e2-standard-2 or n2-standard-2

  • 100 GB Persistent Disk

  • Static external IP

  • A new EVM-compatible wallet (for node registration and rewards)

🪙 Step 1: Create a New Wallet & Fund It

  1. Create a wallet using MetaMask or any EVM-compatible wallet

  2. Export the private key ⚠️ Never use your main wallet for node operation

    📺 Watch: How to Export Private Key from MetaMask

  3. Fund it with Sepolia ETH on Base using the Alchemy faucet: 👉 Base Sepolia Faucet – Alchemy

🔌 Step 2: Get Your WebSocket URLs

Webhash requires two WebSocket URLs: 1️⃣ One for Base Sepolia 2️⃣ One for Ethereum Mainnet

🔹 Option A: Using Alchemy (Recommended)

You only need one app to get both URLs:

  1. Go to the Alchemy Dashboard and log in

  2. Click "Create App"

    • Name: Webhash Node

    • Chain: Base

    • Network: Base Sepolia

  3. After the app is created, click "Configure" (top right)

  4. Under "Add Chains", enable Ethereum → Mainnet

  5. Now go back to the app dashboard:

    • Click the "Network" tab

    • Copy the WebSocket URL for Base Sepolia

    • Then switch to Ethereum Mainnet and copy its WebSocket URL

✅ Examples:

  • Base Sepolia: wss://base-sepolia.g.alchemy.com/v2/your-api-key

  • Ethereum Mainnet: wss://eth-mainnet.g.alchemy.com/v2/your-api-key

📌 Ensure both URLs start with wss://. HTTP URLs are not supported.

🔹 Option B: Using QuickNode

  1. Go to QuickNode

  2. Create two endpoints:

    • One for Base Sepolia

    • One for Ethereum Mainnet

  3. Go to each endpoint’s dashboard

  4. Copy the WebSocket URL from the WebSockets tab

✅ Examples:

  • Base Sepolia: wss://your-node.base-sepolia.quiknode.pro/your-key/

  • Ethereum Mainnet: wss://your-node.ethereum.quiknode.pro/your-key/

📌 Again, make sure to copy the wss:// URLs only. HTTP endpoints won't work.

🖥 Step 3: Launch a VM Instance on GCP

  1. Go to Google Cloud Console → Compute Engine → Create VM

  2. OS: Ubuntu 22.04 LTS

  3. Machine type: e2-standard-2 or n2-standard-2

  4. Add a 100 GB Persistent Disk

🔐 Step 4: Configure Firewall Rules

  1. Navigate to VPC Network → Firewall

  2. Create a new rule:

    • Allow TCP/UDP on port 4001

    • Apply rule to your VM instance

🌍 Step 5: Assign a Static IP

  1. Go to VPC Network → External IP Addresses

  2. Reserve a new static IP

  3. Assign it to your VM instance

⚙️ Step 6: Run the Setup Script

SSH into your VM instance and run:

curl -fsSL https://raw.githubusercontent.com/WebHash-eth/hash-node-setup/refs/heads/main/scripts/setup.sh > setup.sh && chmod +x setup.sh && ./setup.sh

📥 Setup Prompts

You’ll be prompted for:

1️⃣ Base Sepolia WebSocket URL Paste your wss:// URL from Alchemy or QuickNode

2️⃣ Ethereum Mainnet WebSocket URL Paste the wss:// URL for Mainnet (for ENS integration)

3️⃣ Enter Your Email for Updates

After entering your Ethereum Mainnet WebSocket URL, you’ll be prompted to enter your email: Please enter your email address: This helps us send you important updates, community news, and reward announcements related to your node activity. 📌 Your email is stored securely and never shared.

4️⃣ Select Storage Directory You'll see this prompt:

Do you want to use a separate disk for storage? (y/n)

  • Type y to specify a custom directory (e.g., /mnt/webhash)

  • Type n to use the default path: /root/.webhash-node-data

The script will continue automatically after your input.

✅ Step 7: Confirm Node Registration Output

Once setup completes, your terminal should show:

vbnetCopyEdit✔ Container node       Healthy
✔ Container pinner     Started
Waiting for node container to be ready...
Configuring node...
Node started with peer ID: 12D3KooW...
Registering node with peer ID: 12D3KooW...
Node registered successfully with peer ID: 12D3KooW...

📌 If you see “Node registered successfully”, your Webhash node is live!
