What is OriginTrail (TRAC)?

OriginTrail runs a Decentralized Knowledge Graph (DKG). It is a network of nodes that stores and serves Knowledge Assets: pieces of structured, verifiable data that carry a record of who published them. The project aims this at AI systems and at supply-chain and compliance data that needs a traceable origin. TRAC is the network's utility token. Publishers pay TRAC to have Knowledge Assets stored for a set period, and node operators stake TRAC to take part and to be picked for that work. For most people, though, TRAC is simply a token sitting in an address.

Where TRAC lives is what confuses people. It started as an ERC-20 on Ethereum, but the DKG runs on several chains, including OriginTrail's own NeuroWeb parachain on Polkadot. The TRAC on those chains is a bridged form of the same token. A balance on one chain does not show up on another, and to use TRAC on the DKG you need it on the chain where you plan to publish or stake. On NeuroWeb, fees are paid in NEURO, not TRAC.

In Tangem, each network where you hold TRAC appears with its own balance. Before the card signs, the screen names the network the transfer goes out on, so you can compare it with what the recipient expects. For a token spread over this many chains, keeping those balances clearly apart on one card is a sensible way to hold it.
