About Trace Labs

Trace Labs seeks to promote a sustainable, equitable, and fair future for individuals and businesses through the power of shared knowledge and human-centric, trust-enhancing technology. We value data privacy, digital sovereignty, and enabling conscious choices on how and with whom people and organizations share their valuable data. That is why we are building a next-generation, decentralized data sharing infrastructure based on open source, privacy-enhancing, human-first principles to achieve a Web3 vision in the wide context of supply chains.

To do this, we use a unique stack of technologies:

  • OriginTrail Technology, including the Decentralized Knowledge Graph, which is hosted on the open permissionless OriginTrail decentralized network. The network operates on the basis of the OriginTrail protocol, which is rooted in blockchains, such as Ethereum and Polkadot. We are evolving the technology together with the OriginTrail community on the principles of open source development and guided by community-developed technical RFCs and discussions through the Trace Alliance Working Groups.
  • The Network Operating System, built to support the Web3 application layer in seamlessly integrating semantic data across existing enterprise networks utilizing the OriginTrail Decentralized Knowledge Graph as a trusted integration layer,
  • Open standards and frameworks such as the Self-Sovereign Identity framework, GS1, and W3C standards, some of which we contribute to through the standards working groups.

Our partners include organizations such as Parity, DigitalOcean, Oracle, British Standards Institution, GS1, the Next Generation Internet initiative, EVRYTHNG, Kakaxi, and many others.

Our offices are located in Ljubljana (Slovenia), Belgrade (Serbia), and Hong Kong, but the right people can join us remotely as well.

What would your day at Trace Labs be like?

As part of Trace Labs, you will have the unique opportunity to use and build solutions on state-of-the-art technology on a daily basis. Because technical novelty requires constant learning, over the years, we’ve become big fans of scrum, self-organizing teams, and evolving solutions from proof of concepts to complete production-ready systems. This usually involves working together with researchers from relevant industries, research institutions, and communities. Trace Labs is part of the Substrate Builders Program, building an OriginTrail Community run blockchain on the Substrate framework together with Parity technologies, core developers of Polkadot.

That means we mostly communicate and document our work in English and are big fans of globally recognized standards, such as GS1 and W3C as well as engineering best practices, such as using the NASA technology readiness level scale.

Applied learning is what we value the most, as this increases the knowledge of the whole organization. You will most likely be engaged in hands-on implementation projects with our partners and clients.
