OriginTrail: From Supply Chains to Verifiable Knowledge for AI
The token behind the DKG, which reached V10 in June 2026
TRAC is the token used to publish and store knowledge on OriginTrail’s Decentralized Knowledge Graph (DKG). Starting in supply-chain tracking, the project now pitches verifiable knowledge for AI.
1. A supply-chain project turned toward AI
OriginTrail began as a supply-chain tracking project and is developed mainly by Trace Labs. Its core technology is the Decentralized Knowledge Graph (DKG): a knowledge graph links people, things and facts like dots and lines, and ‘decentralized’ means it is stored together by many participants’ computers (nodes), not by one company.
TRAC is the network’s utility token (a token for paying for its services), issued on Ethereum as an ERC-20 (Ethereum’s token standard). On the Crypto Nation map, TRAC stands in Ethereum City (the capital), because it was first issued on Ethereum. Its maximum supply is fixed at 500 million tokens.
2. Publish, fingerprint, store
When a user, app or AI agent (a program that acts on its own) publishes knowledge, DKG nodes store the content, while the blockchain records only a ‘fingerprint’ (hash) and an ownership record. Recomputing it from the stored content and comparing it with the on-chain record shows whether anything changed after publication. The project calls such a unit of knowledge a ‘Knowledge Asset’.
Publishers pay TRAC as a storage fee, and node operators lock it up (staking) to take part and earn those fees. The DKG takes a multichain approach, not tied to one blockchain. TRAC exists on Ethereum and on Base (a layer-2 chain built on Ethereum to be faster and cheaper), and the network has also used Gnosis and NeuroWeb (a parachain, meaning an independent chain attached to Polkadot). Chain roles can change between versions, so check the official docs.
3. Uses and recent milestones
OriginTrail first targeted supply chains, keeping trustworthy records of where a product came from and how it moved. It now promotes ‘Trusted AI’: to counter wrong answers (hallucinations) and misinformation, it argues, AI should draw on knowledge whose source and owner can be checked.
In mid-2025 the DKG V8.1 update began rolling out on mainnet (the live network). The project’s June 2026 recap, posted in early July, announced the launch of DKG V10, and said Trace Labs had unveiled ‘nOS’ (Network Operating System), infrastructure for AI agents.
4. Things to know
‘Verifiable’ has limits: the DKG can show who published something and that it has not changed since, but not that it is true, so quality rests on the publisher. Trace Labs leads development, so the project depends on one team, and each major version asks node operators and stakers to migrate (the docs have a V8-to-V10 staking and migration page).
New smart contracts (programs that run themselves on a blockchain) carry bug risk; the docs list a ‘pre-mainnet bug bounty’ (a reward for reporting security flaws) as closed. Moving TRAC between chains can involve bridges (links that carry tokens across chains), which are generally seen as high-risk. Rivals include decentralized storage networks, AI-agent platforms and ordinary cloud databases.
