The place can I obtain a snapshot of the Lightning community topology?
I need to examine the properties of the Lightning community graph. Is there a strategy to get hold of a fairly recent snapshot containing nodes and channels (say, in JSON format)? There are a number of explorers accessible (e.g. listed in this query), however AFAIK none of them supplies the underlying information for obtain.
(I may simply launch my very own node and question the info with
allchannels or the same command, however that requires synching a non-pruned full node, which I am attempting to keep away from in the intervening time.)
UPD: 1ML does present some JSON (search for the JSON button on varied pages). For instance, https://1ml.com/testnet/node?json=true provides the JSON description of the highest 50 nodes. I have never discovered the best way to get this information for all nodes although.
UPD2: a associated query: Acquiring Lightning community graph information.
