OriginTrail Decentralized Knowledge Graph (DKG), hosted on the OriginTrail Decentralized Network (ODN) as trusted knowledge infrastructure, is shared global Knowledge Graph of Knowledge Assets. Running on the basis of the permissionless multi-chain OriginTrail protocol, it combines blockchains and knowledge graph technology to enable trusted AI applications based on key W3C standards.
The OriginTrail tech stack is a three layer structure, consisting of the multi-chain consensus layer (OriginTrail layer 1, running on multiple blockchains), the Decentralized Knowledge Graph layer (OriginTrail Layer 2, hosted on the ODN) and Trusted Knowledge applications in the application layer.
Further, the architecture differentiates between the public, replicated knowledge graph shared by all network nodes according to the protocol, and private Knowledge graphs hosted separately by each of the OriginTrail nodes.
Anyone can run an OriginTrail node and become part of the ODN, contributing to the network capacity and hosting the OriginTrail DKG. The OriginTrail node is the ultimate data service for data and knowledge intensive Web3 applications and is used as the key backbone for trusted AI applications (see https://chatdkg.ai)
Knowledge Asset is the new, AI‑ready resource for the Internet
Knowledge Assets are verifiable containers of structured knowledge that live on the OriginTrail DKG and provide:
- Discoverability - UAL is the new URL. Uniform Asset Locators (UALs, based on the W3C Decentralized Identifiers) are a new Web3 knowledge identifier (extensions of the Uniform Resource Locators - URLs) which identify a specific piece of knowledge and make it easy to find and connect with other Knowledge Assets.
- Ownership - NFTs enable ownership. Each Knowledge Asset contains an NFT token that enables ownership, knowledge asset administration and market mechanisms.
- Verifiability - On-chain information origin and verifiable trail. The blockchain tech increases trust, security, transparency, and the traceability of information.
By their nature, Knowledge Assets are semantic resources (following the W3C Semantic Web set of standards), and through their symbolic representations inherently AI ready. See more at https://chatdkg.ai
