I'm afraid I'm losing you here. The node advertises himself to everyone he is connected to and in/or out, those nodes pass along those advertisements. When I receive an advertisement from a node I do not know how far away the advertised peers is, presumably I can accurately exclude it from being 0-hops— itself—) 1 or more should be indistinguishable. Is there a reason that they're distinguishable that I'm missing? Can you explain to me how you propose to produce this mapping? ------------------------------------------------------------------------------ _______________________________________________ Bitcoin-development mailing list Bitcoin-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bitcoin-development
