Without looking at the source code, let's assume the probability for this is 2^(-128) for a keyspace of 128 bits. See <a href="http://en.wikipedia.org/wiki/Universally_Unique_Identifier#Random_UUID_probability_of_duplicates">here</a> for a perspective on how probable it is with a 122 bit collision.<br/><br/>However, if something similar to the <a href="http://lwn.net/Articles/282230/">Debian ssl-scandal happens</a>, similar keys could indeed be generated. The effect of an individual generating an existing key, is (if I understand it correctly) in effect to make a copy of wallet.dat. Not good at all, but not devastating for all the members of the p2p network.</div> text/html
