The Decentralised Knowledge Graph

Trace Labs specialises in a new technology called decentralised knowledge graphs. Layered on blockchain technology, these knowledge graphs – or smart databases – will be a key part of the next iteration of the internet – known as ‘web 3’.

Powering search and more

To understand the importance of knowledge graph technology you only have to look at what Google has achieved since they launched the technology back in 2012. Because not only do knowledge graphs power Google search, but Amazon shopping and numerous smart phone apps like UBER.

So what has changed?

All these knowledge graphs are centralised – built and maintained by the tech giants. But it has become ‘decentralised’. What we mean by that is that now, anyone with a computer, internet access a little knowhow can participate – essentially, you can help to build the foundations of web 3.

Applications of decentralised knowledge graphs

Decentralised knowledge graphs – or DKG – open up exciting new opportunities for businesses and institutions. The tech is already being used by the BSI – the British Standards Institute – for supply chain management of medicines and a training certificate verification system.

“We are delighted to be partnering with the leading blockchain provider, [Trace Labs]. The many sectors and communities we serve desire greater transparency of their global operations and OriginTrail’s distributed ledger technology allows us to build a robust and immutable verification ecosystem.”

Pietro Foschi, BSI

The British Standards Institute envisage DKG technology to help businesses in food and healthcare industry to “comply with regulations and standards” and “Meet customer expectations concerning products features and claims (safety, quality and other attributes)”. Read the full article by BSI here.

Use case: verify training and qualifications

In the latest use case, BSI launched a training certificate verification solution powered by the Origin Trail decentralised knowledge graph. On completion of a BSI course, a student can share with potential employers a blockchain-verified training certificate to demonstrate their training credentials are genuine.

Over the next year or so, we can expect to see more big names using the technology.

Impact on Industry

Industries that can potentially benefit from decentralised knowledge graph technology are numerous, here are a few.

  • Supply chain
  • E-commerce
  • Manufacturing
  • Healthcare
  • Food
  • Pharmaceutical

What is a decentralised knowledge graph node?

Without getting too technical, the best way we can describe a decentralised knowledge graph node is as follows:

Think of a container – an empty container – it is yours. You own it. You’re responsible for it. You maintain it and you pay for its upkeep.

A network of containers

Your container is not alone. It is connected by a cord to other containers owned by people all over the world. The containers are joined together to make a network where all containers communicate with each other.

Give it a commercial use

Because the container is empty it has no function, no purpose. It is just an empty vessel. So let’s give it a purpose. What do we want it to do? Let’s give it a commercial use – something businesses can use.

Smart databases

As mentioned web applications and smart phone apps rely on smart databases – or ‘knowledge graphs’. When you do a Google search or ask Alexa something it is relying on smart databases to make a good guess as to what info you want.

So there is a commercial demand for smart databases – businesses building apps need them for their apps to work. So we are gonna add a smart database to our container. Now it is not just a container – it is a smart database connected in a network with which an app built by a participating business can interact.

This is a decentralised knowledge graph node.

Decentralised knowledge graphs are graphs ‘By the people’

Unlike the ‘centralised’ knowledge graphs developed by the tech giants, decentralised knowledge graph nodes can be set up and run by you and me. In this way, you could say a DKG is a knowledge graph ‘by the people’. Not one company or person is responsible for all nodes. That is why we call it decentralized.

Your responsibility

Those that run DKG nodes or ‘node runners’ have a key responsibility. Because only if they keep the node ‘alive’ can businesses utilised their power.

Can you earn crypto by running a Decentralised Knowledge Graph node?

Yes – Any business that writes data to the decentralised knowledge graph node must pay $TRAC cryptocurrency to the node owner. Node owners automatically receive crypto without human intervention. As node owner, you must keep your node ‘alive’ and well maintained. Reliability is key to earning rewards.
