OpenLedger has introduced a Proof of Attribution (PoA) system to enhance the transparency and verifiability of AI actions. This system records the entire data call path, reasoning process, and subsequent on-chain operations, ensuring AI behavior can be verified. By partnering with ChainbaseHQ, which provides structured cross-chain on-chain data, PoA anchors its traceability mechanism to verifiable input sources, moving away from reliance on retrospective analysis. This collaboration aims to advance Web3 towards more transparent, trustless, and data-centric AI systems.
