OpenLedger is the "AI version of Ethereum+GitHub" that makes AI open source, trustworthy, traceable, and accessible to everyone. I recently finished reading the white paper "Proof of Attribution" by @ Openledger HQ, which has made me increasingly realize that in the latter half of AI development, the issue of ownership confirmation in the entire process of AI contribution will be the biggest pain point for traditional AI at present. OpenLedger combines the currently popular AI+Blockchain solution, effectively addressing the aforementioned pain points. According to a research report by @ MessariCrypto, the AI market is expected to reach a market value of over 2 trillion US dollars by 2030, and its potential is self-evident. Today, we will analyze the new AI powerhouse OpenLedger and three early free participation opportunities.
