  "whatItIs": "7050 is not registered with IANA. It is the Hyperledger Fabric convention: an orderer's General.ListenPort defaults to 7050, and Fabric's production ordering-node checklist documents it as the port the orderer listens on for client and peer gRPC traffic. Peers submit endorsed transactions here and pull blocks from it, so on a Fabric network it is the busiest single endpoint. If you see 7050 open it is almost certainly a blockchain node, usually in a Docker Compose or Kubernetes deployment alongside peers on 7051.",
