Proof of Useful Work (POUW) is a paradigm shift in the world of blockchain and cryptocurrency, designed to address the sustainability concerns of traditional Proof of Work (PoW) systems. Where PoW requires miners to use high amounts of computational power to mine blocks, often criticized for its intensive energy use without direct productive output, POUW redirects this computational capacity towards meaningful AI tasks. In the AIPG ecosystem, POUW incentivizes node operators to provide inference on localized large language models (LLM) and host AI art model generation via technology like Stable Diffusion. This convergence of blockchain and AI tasks not only validates transactions but also produces valuable AI services, thereby utilizing the energy consumed in a manner that contributes constructively to the community and the broader field of AI.
