      There are two types of Bitcoin exchanges: those which have been compromised, and those that will be.

      @marcan42 They are all vulnerable to some extent, so the real trade-off is between stop-gap security/availability (cold storage)

      @brandynwhite building an isolated system to manage the master wallet that imposes rate limits based on trend data isn't rocket science.

      @marcan42 That's right, but same trade-off applies. If you let your learning rate (for alpha blending w/e) get too low = lag, too high=die

      @marcan42 Something I've been advocating is having multiple implementations (based on a spec), if they don't all agree then drop the trans.

      @marcan42 That prevents a large class of dumb bugs by requiring all implementations agree, it's safe to just drop tricky cases, fix by hand

      @brandynwhite that's a fair idea. I'd still have a rate limit on the backend wallet, though.

          @marcan42 btc has scripting built in for verification, that could be part of a solution (mostly disabled atm) https://webcache.googleusercontent.com/search?q=cache:7rxOTVdfxZAJ:https://bitcoin.it/wiki/Script+&cd=1&hl=en&ct=clnk&gl=us …
