OpenLedger is an innovative Layer-1 blockchain protocol designed for the deep integration of artificial intelligence (AI) and blockchain. It evolved from the OpenDB project in mid-2024 and officially launched its mainnet in September 2025. As a representative of "AI blockchain," OpenLedger is committed to addressing issues of data opacity, centralized control, and unfair compensation for contributors in traditional AI development by building an open ecosystem through decentralized technology. Users can upload datasets, train dedicated AI models, deploy applications, and receive on-chain rewards based on data usage frequency. Its core innovation lies in the concept of "Payable AI," which puts the entire AI lifecycle (data contribution, model training, inference deployment) on-chain to ensure transparent traceability and automatic revenue sharing. For example, the system tracks the impact of data on AI outputs through a Proof of Attribution mechanism and allocates profits proportionally. Unlike general-purpose blockchains (such as Ethereum), OpenLedger is optimized for high-frequency AI tasks, supporting high throughput, low fees, and verifiable data tracking. In addition, the project provides tools such as OpenLoRA (an engine for efficiently running multiple models) and ModelFactory (a no-code fine-tuning platform) that allow developers to build dedicated AI models without complex programming, significantly lowering the technical barrier. OpenLedger's native token OPEN has a total supply of 1 billion tokens, with a reasonable distribution structure: 40% to the community, 25% to the ecosystem, 15% to the team, 5% to liquidity, etc., emphasizing "contributor first." As of September 17, 2025, the price of OPEN is approximately 0.86 USD, with a 24-hour trading volume exceeding 150 million USD, a circulation of about 215 million tokens, and a market cap ranking of approximately 248. Analysts predict that benefiting from a global blockchain market compound annual growth rate (CAGR) of 32.72%, OPEN may rise to 2.07 USD by the end of 2025, especially with the expansion of the AI market (expected to reach 36.8 billion USD by 2033), its value capture potential is significant. OPEN is not only a utility token but also drives the AI economic closed loop, serving as gas fees (on-chain transaction fuel), inference fees (running AI models), and reward mechanisms (Proof of Attribution sharing), deeply embedded in the AI process. Users can earn OPEN by uploading data or training models, and developers must pay OPEN when deploying applications to ensure stable token demand $OPEN @OpenLedger #OpenLger
