    Hello, The project is about building a decentralized P2P network (platform) based on the IPFS or libp2p network framework. The project has 7 main phases: 1) Build a P2P network, where each node/peer participating in this network must be capable of discovering, routing, messaging, file sharing, and pinging other nodes/peers. This can be done through the IPFS or LİBP2P. This step is very easy you just need to install one of the above-mentioned protocols and then deploy it as a private (isolated) network via "Swarm / DHT". 2) Setup a VPN based on hyperspace to enable Master and Worker nodes be accessible in RAY (if you can manage it through libp2p then this task can be skipped). 3) Resource management: each node/peer must be able to manage its resources (i.e. RAM, CPU, and storage)....
