...you're suggesting - or rather insisting - that a double spend is a factor not only here (DEM) but on any blockchain generally? Based upon what?
I might have missed it, but didn't see any logs posted in the last few pages (since you guys started arguing) of this forum. What'cha got?
Since I'm far too lazy to explain it all (and post all of the logs), I'll let the Bitcoin wiki do the talking:
Reorganize
A block chain reorganize (or reorg) happens when one chain becomes longer than the one you are currently working on*. All of the blocks in the old chain that are not in the new one become orphan blocks, and their generations are invalidated... The number of confirmations for transactions may change after a reorg, and transactions that are not in the new chain will become "0/unconfirmed" again. If a transaction in the old chain conflicts with one in the new chain (as a result of double-spending), the old one becomes invalid.
*Or in the case of eMark, "when one chain has an earlier timestamp than the one you are currently working on"
