My proposal? I won’t take credit for Satoshi’s work, it was his proposal:

You either misunderstood the parent or are being deliberately disingenuous.

He/she asked, in effect: How do you plan to deal with the blockchain growing exponentially instead of linearly? And how much acceleration do you think is reasonable?

I needed to clarify that it wasn’t my proposal, as to how to gradually approach this, test nets are already deployed on many of the uncapped networks, I believe you’ll enjoy this great presentation by Peter Rizun and Andrew Stone, they’re far smarter than I’ll ever be: https://youtu.be/5SJm2ep3X_M

Strictly speaking it wasn't his, it was the originator of that thread, jgarzik, and satoshi replied "We can phase in a change later if we get closer to needing it.", which doesn't strike me as a ringing endorsement.

At any rate, the suggestion was for one increase, not an infinite sequence of increases, which your suggested exponential growth amounts to.

One increase every time its theoretical limit is approached, which becomes exponential as transaction growth becomes exponential.

If it doesn't, then Bitcoin is dead. It has no future.
