Bitcoin Alpha
This is a user–user trust/distrust network, from the Bitcoin Alpha platform,
on which Bitcoins are traded. Each directed edge represents trust or distrust
on a scale from −10 to +10. Positive edge weights denote trust, and negative
edge weights denote distrust. An edge weight of zero does not appear.
