This is the existential&#xA;&gt; question behind block size.&#xA;&gt;&#xA;&gt; Are we trying to build a system that can handle Paypal volumes?  VISA&#xA;&gt; volumes?&#xA;&gt;&#xA;&gt; It&#39;s not a snarky or sarcastic question:  Are we building a system to&#xA;&gt; handle all the world&#39;s coffees?  Is bitcoin&#39;s main chain and network -&#xA;&gt; Layer 1 - going to receive direct connections from 500m mobile phones,&#xA;&gt; broadcasting transactions?&#xA;&gt;&#xA;&gt; We must answer these questions to inform the change being discussed&#xA;&gt; today, in order to decide what makes the most sense as a new limit. &#xA;&gt; Any responsible project of this magnitude must have a better story&#xA;&gt; than &#34;zomg 1MB, therefore I picked 20MB out of a hat&#34;  Must be able to&#xA;&gt; answer /why/ the new limit was picked.&#xA;&gt;&#xA;&gt; As G notes, changing the block size is simply kicking the can down the&#xA;&gt; road:&#xA;&gt; http://gavinandresen.ninja/it-must-be-done-but-is-not-a-panacea  &#xA;&gt; Necessarily one must ask, today, what happens when we get to the end&#xA;&gt; of that newly paved road.&#xA;&gt;&#xA;&gt;&#xA;&#xA;Accepting that outcomes are less knowable further into the future is not&#xA;the same as failing to consider the future at all.  A responsible&#xA;project can&#39;t have a movie-plot roadmap.  It needs to give weight to&#xA;multiple possible future outcomes.&#xA;http://en.wikipedia.org/wiki/Decision_tree&#xA;&#xA;One way or another, the challenge is to decide what to do next.  Beyond&#xA;that, it&#39;s future decisions all the way down. &#xA;&#xA;Alan argues that 7 tps is a couple orders of magnitude too low for any&#xA;meaningful commercial activity to occur, and too low to be the final&#xA;solution, even with higher layers.  I agree.  I also agree with you,&#xA;that we don&#39;t really know how to accomplish 700tps right now.&#xA;&#xA;What we do know is if we want to bump the limit in the short term, we&#xA;ought to start now, and until there&#39;s a better alternative root to the&#xA;decision tree, it just might be time to get moving.</html></oembed>
