If you call your 1 minute blocks "instant transactions" how would you call the 10 secs of Bitshares? Faster Than Light confirmations?
its not implemented yet.. shaded circle = not yet finished.
for the record.. node actually does have instant transactions of around 1-3 seconds i think.
The above "technologytree" gave the impression that it's already implemented, by the time this will be implemented(IF it's implemented at all because afaik its almost a year since we heard about "instant transactions") the competition will also have something better , my point is that this very moment we have 1 minute for NXT and 10 sec for bitshares
and both are trying to improve those times.
