      .@jm maybe an immutable, un-GCable global transaction log is a bad idea

      @bascule @jm won't adding a distributed GC to the blockchain be very tricky and prone to abuse?

      @whitequark @jm there are better solutions to the double spending problem then a lottery for completing a proof-of-work function first

      @bascule @whitequark Yeah the more I’ve learned about the algorithm behind btc, it seems a little suboptimal. :)

      @jm @whitequark one alternative is to leak a user's private key if they double spend

      @bascule @jm how would you safely implement that?

      Replying to @whitequark

      @whitequark @jm make double spending nonce reuse with any *DSA, which Bitcoin already uses. It's catastrophic (see e.g. PS3 master key)

      @bascule @jm couldn't you single-spend the exact amount you need to a temporary address and then double-spend from there?

      @whitequark @jm i.e. if double spending is detected, identify the culprit in the DAG and blacklist his whole spending history

          @bascule @jm what about mixers/exchanges? that would be a DoS against their withdrawal addresses

          @bascule @jm for your scheme to work you'd need some kind of enforceable identity attached to keys, and I don't see how that happens

          @whitequark @jm more or less apply the machine learning techniques already used for credit card fraud to an altcoin

          @bascule @jm "machine learning" is another way of saying "I don't really know what I'm doing" :p
