This is the existential\n\u003e question behind block size.\n\u003e\n\u003e Are we trying to build a system that can handle Paypal volumes?  VISA\n\u003e volumes?\n\u003e\n\u003e It's not a snarky or sarcastic question:  Are we building a system to\n\u003e handle all the world's coffees?  Is bitcoin's main chain and network -\n\u003e Layer 1 - going to receive direct connections from 500m mobile phones,\n\u003e broadcasting transactions?\n\u003e\n\u003e We must answer these questions to inform the change being discussed\n\u003e today, in order to decide what makes the most sense as a new limit. \n\u003e Any responsible project of this magnitude must have a better story\n\u003e than \"zomg 1MB, therefore I picked 20MB out of a hat\"  Must be able to\n\u003e answer /why/ the new limit was picked.\n\u003e\n\u003e As G notes, changing the block size is simply kicking the can down the\n\u003e road:\n\u003e http://gavinandresen.ninja/it-must-be-done-but-is-not-a-panacea  \n\u003e Necessarily one must ask, today, what happens when we get to the end\n\u003e of that newly paved road.\n\u003e\n\u003e\n\nAccepting that outcomes are less knowable further into the future is not\nthe same as failing to consider the future at all.  A responsible\nproject can't have a movie-plot roadmap.  It needs to give weight to\nmultiple possible future outcomes.\nhttp://en.wikipedia.org/wiki/Decision_tree\n\nOne way or another, the challenge is to decide what to do next.  Beyond\nthat, it's future decisions all the way down. \n\nAlan argues that 7 tps is a couple orders of magnitude too low for any\nmeaningful commercial activity to occur, and too low to be the final\nsolution, even with higher layers.  I agree.  I also agree with you,\nthat we don't really know how to accomplish 700tps right now.\n\nWhat we do know is if we want to bump the limit in the short term, we\nought to start now, and until there's a better alternative root to the\ndecision tree, it just might be time to get moving."}
