Dolphin is an innovative project focused on advancing AI model development and enabling distributed inference. It introduces a decentralized network designed to optimize the use of GPU resources by connecting gamers and GPU owners. The core component of Dolphin is its Decentralized AI Inference Network. This platform allows users to utilize their idle GPUs, contributing to the network's processing power. By doing so, participants can earn DPHN tokens as compensation, which can be utilized for inference services or traded on the market to recover GPU costs. The Dolphin Network ensures its reliability and security through advanced measures, including encryption, random validation sampling, and cryptoeconomic bonding. This structure fosters a trustworthy environment for all users involved in the network. Overall, Dolphin aims to create a sustainable ecosystem that benefits GPU owners while enhancing the efficiency of AI inference processes. With its unique approach, it stands to redefine how computational resources are utilized in the AI landscape.
