OPEN has officially launched its mainnet, introducing a new era in on-chain AI fairness. The project aims to rectify the imbalance in reward distribution for data contributors in AI development through its 'Proof of Attribution' mechanism. This system rewards verified data contributors with OpenLedger's native token, incentivizing participation and contribution. As users increase their contributions, they can ascend leaderboards for enhanced visibility and value. Additionally, users have the opportunity to build 'datanets' to collaboratively train AI systems and share in the generated value.
