Janction is a distributed AI infrastructure stack that pools idle processor resources into a GPU and high-performance compute market. A blockchain and data-availability layer records data ingestion, task execution and reward flows, while the resource layer groups GPUs into virtual units and exposes them as microservices for parallel AI workloads. Users supply idle GPUs or other processors, which are containerized and scheduled through colocation algorithms, and consumers select resources and pricing through the GPU Marketplace, where Proof of Contribution and pricing functions govern allocation and compensation.
