I guess my question (and perhaps that's what Jorge is after): do
you feel that blocks should be increased in response to (or for
fear of) such a scenario.
I think there are multiple reasons to raise the maximum block size,
and yes, fear of Bad Things Happening as we run up against the 1MB
limit is one of the reasons.
I take the opinion of smart engineers who actually do resource
planning and have seen what happens when networks run out of
capacity very seriously.
This is a fundamental disagreement then. I believe that the demand is
infinite if you don't set a fee minimum (and I don't think we should),
and it just takes time for the market to find a way to fill whatever
is available - the rest goes into off-chain systems anyway. You will
run out of capacity at any size, and acting out of fear of that
reality does not improve the system. Whatever size blocks are actually
produced, I believe the result will either be something people
consider too small to be competitive ("you mean Bitcoin can only do 24
transactions per second?" sounds almost the same as "you mean Bitcoin
can only do 3 transactions per second?"), or something that is very
centralized in practice, and likely both.
What if we reduce the block size to 0.125MB? That will allow 0.375tx/s.
If 3->24 sounds "almost the same", 3->0.375 also sounds almost the same.
We will have 50000 full nodes, instead of 5000, since it is so
affordable to run a full node.
If 0.125MB sounds too extreme, what about 0.5/0.7/0.9MB? Are we going to
have more full nodes?
No, I'm not trolling. I really want someone to tell me why we
should/shouldn't reduce the block size. Are we going to have more or
less full nodes if we reduce the block size?
