Origin Trail is a web3 infrastructure project combining a knowledge graph and blockchain technologies to create a neutral, inclusive ecosystem. The OriginTrail network is open source and permissionless, which increases transparency and security. One of the core features of OriginTrail is the multi-chain Decentralized Knowledge Graph (DKG) that runs on three blockchains: Ethereum, Polygon and Gnosis. Additionally, the OriginTrail Parachain, a layer-one blockchain component built to work with the Polkadot relay chain, extends the DKG's capabilities. The ecosystem is designed to facilitate real-world adoption of web3 technologies, particularly in the supply chain sector. Its tokenomics design leverages network effects by seamlessly integrating both network layers and its innovative Uniform Asset Locators (UALs) for increased asset discoverability. Overall, OriginTrail aims to leverage partnerships and the interoperability capabilities of Polkadot to drive use cases in various industries, including DeFi, real-world asset collateralization, the metaverse, the Internet of Things (IoT), and more....
