I once spoke with some engineers who built and run one of those high-speed electronic trading networks/exchanges. Their time to match trades was something like 50 microseconds. Their serious members colocated their trading systems in their datacenter because it was so critical to eliminate the propagation delay. I guess I don't see the need to do bitcoin crypto transactions at that speed any more than the other high-speed exchanges need to rapidly move stock certificates, hard cash, or perform ACH/EFTs. > (Gee I wonder if I should file a patent on that idea :P ) Maybe you could be the next Certicom! ^_^ > This and other aspects of high frequency trading forces a credit > exposure to the trades, which requires someone to step in and control > that credit. But the term "high speed electronic exchange" seems to mean exactly this, almost by definition. - Marsh _______________________________________________ cryptography mailing list cryptography(a)randombit.net http://lists.randombit.net/mailman/listinfo/cryptography ----- End forwarded message ----- -- Eugen* Leitl leitl 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 --===============5315772228057598216==--
