That's NOT true, once the secure newsgroup exists: the list of participating machines can be posted to the newsgroup! :-O The list can be amended as time goes on (with each amendment, naturally, signed by a plurality of the participating machines in order to be valid). You can verify the entire sequence of such amendments, starting with the Founding Fathers and ending with the current state of affairs. If you haven't been around since the dawn of time, just make sure that the signatures of some machines you trust, or a whole lot of prominent people, are attached to the list. ---- I haven't seen much comment yet. I was expecting, at least, something about the pros and cons of using a distributed voting protocol to establish a global consensus. Does anyone have anything to add, or are you all stunned into silence by the brilliance of my proposal? ;-) M.
