Akash Network is a decentralized cloud computing marketplace built on the Cosmos SDK that connects users who need computing resources with providers who have spare capacity. Often called the 'Airbnb for cloud compute,' Akash offers a permissionless marketplace for GPU and CPU resources at significantly lower costs than centralized cloud providers. The platform supports containerized workloads and has become popular for AI/ML model training and inference, making it a key player in the decentralized physical infrastructure (DePIN) sector.
