I am concerned with discovering paths from senders whose node you do not run to potential receivers. In accordance with https://api.lightning.neighborhood/?python#queryroutes , you are able to do that by specifying the parameter source_pub_key to be any public key you would like and never simply yours. In actuality, this doesn’t work because the querryroutes command doesn’t help some other parameters than:
OPTIONS:
dest worth: the 33-byte hex-encoded public key for the fee vacation spot
amt worth: the quantity to ship expressed in satoshis
fee_limit worth: most payment allowed in satoshis when sending the fee
fee_limit_percent worth: proportion of the fee’s quantity used as the utmost payment allowed when sending the fee
final_cltv_delta worth: variety of blocks the final hop has to disclose the preimage
use_mc: use mission management chances
Does anybody know if there was once a chance of including source_pub_key and it was eliminated or it by no means existed within the first place? Extra importantly, is there a technique to assemble paths from a supply to a vacation spot, when you do not truly run the node of the supply and you do not care about truly forwarding funds and packets however fairly simply establishing paths in accordance with the shortest paths algorithm of lnd.
