Welcome to official OriginTrail Docs
The OriginTrail tech stack is purposefully designed to bring real world assets into the Web3, enabling discoverability, verifiability and connectivity of physical and digital assets in one coherent Web3 data ecosystem. It is built on a set of tools and protocols evolving as the semantic layer of Web3. It is a two-layer system connecting blockchain technology on "Layer 1" and knowledge graph technology on "Layer 2", supporting the OriginTrail Decentralized Knowledge Graph (DKG).
The core unit of the Layer 2 DKG network - the OriginTrail DKG node - is the ultimate data service for your Web3 applications. OriginTrail DKG is a powerful Web3 backend, and together with DKG SDKs you can create graph-native Web3 applications, interfacing with verifiable assets on the DKG.
The DKG enables you to:
- Easily discover, query and integrate datasets from multiple sources
- Monetize your APIs and data, using fungible and non-fungible tokens (knowledge tokens)
- Easily build custom verifiable data pipelines
- Integrate with existing SSI & blockchain tooling
