**[OpenLedger Launches OPEN Mainnet, Supporting AI Data Traceability and Creator Payments]** OpenLedger has announced the launch of the OPEN mainnet, a decentralized network designed to provide data traceability for artificial intelligence systems and an automated compensation mechanism for contributors. Users can upload datasets to a shared "data network," where developers can train models and complete payments via smart contracts. This model draws inspiration from the economic frameworks of creator platforms like YouTube, helping researchers, writers, and domain experts earn revenue. The core of the OPEN mainnet is the "Proof of Attribution" system, which records the origins of datasets, models, and agents on-chain, tracing AI output back to the original contributors. This enables verifiable credit records and automated payments. Earnings are distributed through the protocol's OPEN token, allowing contributors to earn passive income when their data is used by models. Last July, OpenLedger completed an $8 million seed funding round led by Polychain Capital and Borderless Capital.
