Without commenting on the merits of this proposal, I=92d just like to corre= ct this common misperception. There is no necessary additional cost to the = network from the count of unspent outputs. This perception arises from an i= mplementation detail of particular node software. There is no requirement for redundant indexing of unspent o= utputs.
