[Bitcoin-development] Block Size Increase

It seems to me like some (maybe most) of the pressure is actually external
from companies that might release something that dramatically increases
"adoption" & transaction rates (and that the data on historic rate of
adoption & slumps is somewhat disconnected from their interests in a quick

It seems like the question actually becomes what is our maximum acceptable
cost (hardware capex & bandwidth & power opex) associated with running a
full node without hardware acceleration and with hardware acceleration
(something which presumably "doesn't exist" yet)? Are we making the
assumption that hardware acceleration for confirmation will become broadly
available and that the primary limiter will become anonymous bandwidth?

Excuse my ignorance, but I imagine somebody must have already looked at
confirmation times vs. block size for various existing hardware platforms
(like at least 3 or 4? maybe a minnowboard, old laptop, and modern desktop
at least?)? Is there an easy way to setup bitcoind or some other script to
test this? (happy to help)

Re Moore's law: yeah, some say stuff like 5nm may never happen. We're
already using EUV with plasma emitters, immersed reflective optics, and
double-patterning... and in storage land switching to helium. Things may
slow A LOT over the next couple decades and I'd guess that a quadratic
increase (both in storage & compute) probably isn't a safe assumption.
