Title: How to find total number of nodes?
Post by: hazzey on April 22, 2011, 03:44:05 PM
I was trying to figure out how the estimate of total bitcoin nodes as shown at http://stats.bitcoin.it/rrd/nodes_total-month.png (http://stats.bitcoin.it/rrd/nodes_total-month.png) is created.  I am guessing that this comes from the number of addresses that the bitcoin client has seen.  Is there a RPC call to get this number? 

I realize that this method would be fairly inaccurate at best.  So does anyone know how I could go about making a similar graph?  Maybe I am way off in my assumption.
