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 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!
