I=E2=80=99ve been pondering this whole scale issue considerably=E2=80=A6an=
d am left with the conclusion that blockchains are ultimately dispute =
resolution mechanisms. The vast majority of crypto negotiation will be =
taking place at levels lesser than global consensus in the future - =
global consensus is just far too expensive to require for every single =
cappuccino. There really is little need to take most cases =
globally=E2=80=A6unless the participants disagree. I=E2=80=99ve =
commented in other places that blockchains are essentially a =E2=80=9Cfix=E2=
=80=9D to the prisoner=E2=80=99s dilemma - they make cooperation the =
equilibrium strategy.

Regardless of whatever linear factor we scale the blockchain by, it is =
simple math to see that any exponential growth (even if for a short =
time) in usage will overwhelm the current network. If we ever intend to =
take bitcoin mainstream, we will most likely experience at least a short =
time of exponential growth=E2=80=A6at least until we either reach an =
inherent limitation or until we saturate. As Pieter said earlier, FAPP =
right now the demand for payments might as well be infinite. We=E2=80=99re=
 nowhere near the ability to service it all.

The block size issue is really a usability issue at this point. There =
are two fundamental things we need to solve:

1) There=E2=80=99s no model for how we=E2=80=99ll introduce a fee =
market, even though the design of Bitcoin fundamentally depends on fees =
for its survival (at least in the current form of the design.)

2) There=E2=80=99s no mechanism for how to perform fee bidding and =
estimation. Most wallets simply have no way to do this without serious =
usability problems.



If we=E2=80=99re going to talk about block fees, let=E2=80=99s keep it =
in the context of these relevant issues and not confound it with the =
scalability issue=E2=80=A6these are two very different issues.
