On the crypto topic that everyone loves to hate, Bitcoin, the expected attack has begun. http://financialcryptography.com/mt/archives/001363.html Philipp Guering and I wrote a paper that explains how this will fall out. http://iang.org/papers/BitcoinBreachesGreshamsLaw.pdf Although in the big picture, this is more about finance not cryptography, there is an engaging question - can cryptography be used to control this sort of issue? It didn't work for Bitcoin, but more judicious uses of crypto can do a lot better, and has done with other designs. The challenge is to get the balance right. iang _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
