Quickstart (test drive the DKG in 5 mins)

Welcome to your first hands-on experience with the OriginTrail Decentralized Knowledge Graph (DKG)! In just a few minutes, you'll publish and retrieve your first Knowledge Asset (KA) using public DKG nodes—no complex setup required.

---

What you’ll do

✨ What you'll accomplish

You'll use the DKG SDK (JavaScript or Python) to:

• Connect to a public DKG node

• Publish a simple Knowledge Asset (KA)

• Retrieve that KA by querying the DKG

No need to run your own node — we'll use public infrastructure so you can dive in instantly!

---

What you’ll need

• Node.js (for JavaScript SDK) or Python (3.8+)

• A Web3 wallet (e.g., MetaMask) with:

  • Test TRAC tokens

  • Test Neuro tokens

• A public DKG node endpoint, which you can find here

Step 2: Publish your first Knowledge Asset

Step 3: Query & retrieve the Knowledge Asset

Or you can use the Python SDK:

query_operation_result = dkg.graph.query(
    """
    PREFIX schema: <http://schema.org/>
    SELECT ?s ?name ?description
    WHERE {
        ?s schema:name ?name ;
           schema:description ?description .
    }
    """
)
print_json(query_operation_result)

📋 What you'll need

Before you start, make sure you have:

1. Development environment:

   • For JavaScript: Node.js (v16 or higher) installed
   • For Python: Python (3.8+) installed
2. Code editor:

   • Visual Studio Code or
   • Cursor or any editor you prefer
3. Web3 wallet with test tokens for the NeuroWeb blockchain:

   • MetaMask or similar wallet
   • Test TRAC tokens for publishing the Knowledge Asset

   • Test NEURO tokens for gas fees

🪙 Getting Test Tokens

1. Join our Discord server
2. Navigate to the #faucet-bot channel

3. Type !help to see available commands

4. Use the bot to get free Test TRAC and NEURO tokens

To receive TRAC on Neuroweb, first acquire NEURO via the faucet to initiate your wallet.
