The OriginTrail Decentralized Network (ODN) is the operating layer of the OriginTrail protocol, an open-source system that pairs blockchain settlement with a knowledge graph so that data about products, assets or other information can be verified and shared without everyone having to trust a single central authority.
The project grew out of a real supply-chain problem: proof of origin is normally scattered across separate, closed company databases, forcing buyers to trust each link in the chain rather than the data itself. OriginTrail lets organizations publish that data as "Knowledge Assets" on a shared, tamper-evident structure called the Decentralized Knowledge Graph (DKG), anchored to public blockchains instead of one company's servers.
ODN is the peer-to-peer network of independently run nodes that store, replicate and serve this graph data off-chain, while proofs and payments settle on connected chains, first Ethereum, later also Polygon, Gnosis and OriginTrail's own NeuroWeb chain. Running a node requires locking a large amount of TRAC as collateral inside the network's smart contracts, which discourages dishonest behaviour because a node caught serving bad data risks losing its stake. Publishers spend TRAC to write new Knowledge Assets, and node operators earn TRAC fees for hosting and validating them, so the token functions as the network's core utility token rather than a purely speculative asset.
Beyond logistics, OriginTrail has expanded toward verifying data for artificial intelligence and real-world assets. Enterprises and standards bodies such as Walmart, the British Standards Institution and GS1 have piloted the network for product authentication, compliance tracking and supply-chain transparency.
