OpenLedger has launched its blockchain platform on Mainnet as of November 19, 2025, aiming to address AI's challenges of bias, opacity, and unequal rewards. The platform transforms data, models, and computing resources into verifiable assets, ensuring fair compensation for contributors. Key features include 'Datanets' for community-curated data pools, 'Proof of Attribution' for tracking and monetizing contributions, and AI interoperability with LayerZero for cross-chain functionality. Backed by Polychain and HashKey Capital, OpenLedger seeks to democratize AI by allowing artists to protect intellectual property, developers to build without silos, and users to own their data economy. The initiative encourages community engagement through 'The Great YAPENING,' where participants can share insights and compete for a share of 250,000 $OPEN tokens.
