G proposed 20MB blocks, AFAIK - 140 tps

A proposed 100MB blocks - 700 tps

For ref,

Paypal is around 115 tps

VISA is around 2000 tps (perhaps 4000 tps peak)

I ask again:  where do we want to go?   This is the existential question behind block size.

Are we trying to build a system that can handle Paypal volumes?  VISA volumes?

It's not a snarky or sarcastic question:  Are we building a system to handle all the world's coffees?  Is bitcoin's main chain and network - Layer 1 - going to receive direct connections from 500m mobile phones, broadcasting transactions?

We must answer these questions to inform the change being discussed today, in order to decide what makes the most sense as a new limit.  Any responsible project of this magnitude must have a better story than "zomg 1MB, therefore I picked 20MB out of a hat"  Must be able to answer /why/ the new limit was picked.

As G notes, changing the block size is simply kicking the can down the road: http://gavinandresen.ninja/it-must-be-done-but-is-not-a-panacea   Necessarily one must ask, today, what happens when we get to the end of that newly paved road.
