I want to know if it is possible to see all nodes, their capacity and channels (of the whole Lightning network)? I am doing some network research and I really have a hard time finding this information, I would love some guidance. I thought by installing a Lightning Node I would be able to get this data by command line? Is this possible via Voltage? In Voltage I cannot write commands like lightning-cli listchannels and lightning-cli listnodes , or with lnd it should be only one API call describechannelgraph .

Lightning Terminal mempool.space I thought by installing a Lightning Node I would be able to get this data by command line? Is this possible via Voltage? Yes, Voltage provides a guide to command with lncli via RPC call.

Alright, so if you want to export the Lightning Network graph, it’s actually pretty doable. If you’re using lnd, you can grab the whole network graph by running the describegraph command. Just type in lncli describegraph, and boom—you get a JSON file with all the nodes and channels. You can save that file and do whatever you need with it. If you’re on c-lightning, it’s a bit different. You’ll need to use the listchannels and listnodes commands to get the data. You can save each of those as JSON files too, like lightning-cli listchannels > channels.json for the channels, and the same for nodes. After you’ve got the data, you can use something like Python’s NetworkX to visualize it, or you can just pop it into one of the Lightning Network explorers if you want a quick look. It’s pretty simple once you know the commands. Let me know if you need any more help!
