@OpenLedger #OpenLedger $OPEN is an innovative Layer-1 blockchain protocol designed for the deep integration of artificial intelligence (AI) and blockchain, evolving from the OpenDB project in mid-2024 and officially launching the mainnet in September 2025. As a representative of "AI Blockchain", OpenLedger is dedicated to solving the 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, ensuring transparent traceability and automatic profit sharing. For example, the system tracks the impact of data on AI outputs through the Proof of Attribution mechanism and allocates profits proportionally. Unlike general blockchains (such as Ethereum), OpenLedger is optimized for high-frequency AI tasks, supporting high throughput, low fees, and verifiable data tracking. Additionally, the project provides tools like OpenLoRA (an engine for efficiently running multiple models) and ModelFactory (a no-code fine-tuning platform), enabling developers to build dedicated AI models without complex programming, significantly lowering technical barriers. The native token of OpenLedger, 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, and 5% for liquidity, 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 capitalization ranking of around 248. Analysts predict that, benefiting from a global blockchain market compound annual growth rate (CAGR) of 32.72%, OPEN could rise to 2.07 USD by the end of 2025, particularly as the AI market expands (expected to reach 36.8 billion USD by 2033), highlighting its significant value capture potential. 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 profit sharing), deeply embedded in the AI process. Users earn OPEN by uploading data or training models, while developers are required to pay OPEN when deploying applications, ensuring stable token demand.
