Welcome to official OriginTrail Docs
OriginTrail ecosystem 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 DKG - the OriginTrail 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
  • Securely share semantic data (knowledge) across systems and dapps​
  • 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
This documentation is structured in 3 sections:
  • Introduction to OriginTrail Decentralized Knowledge Graph - we recommend starting here
  • For developers and node operators: explaining how to build the DKG and contribute to the OriginTrail Decentralized Knowledge Graph by running network nodes
  • Additional resources and links
Note: This site is primarily built for developers and OriginTrail network node runners - if you are looking to learn more about the OriginTrail ecosystem, please visit the official website.
This site is a constantly updated, work-in-progress documentation built by the OriginTrail community and core developers. We appreciate any feedback, improvement ideas and comments. To provide updates, please submit them as pull requests on the docs Github repo. For feedback and discussions please use Github issues.
