OriginTrail

OriginTrail is a decentralized knowledge graph (DKG) infrastructure that aims to let data be shared in a verifiable and interconnected way. The project emerged around 2018 with a focus on supply chain data traceability and gradually evolved into a framework intended to help AI systems work with verifiable information of known provenance. Development is carried out by a company called Trace Labs.

On the network, data is published as knowledge assets; entries proving their authenticity are written to the blockchain, while the content itself is held by DKG nodes. The DKG works in integration with different chains, including the NeuroWeb network in the Polkadot ecosystem as well as Base and Gnosis. The project positions the DKG as infrastructure that AI agents can use as a shared and verifiable memory layer.

TRAC is a token issued under the Ethereum token standard; it is used as the means of payment for publishing knowledge assets and as staking collateral for DKG nodes. On Lzzo.com, the OriginTrail price is based on DefiLlama's US dollar reference data and is shown for information only.
