Quantifying the deadweight loss puts meat on the point I have been raising for many months, that it is still too early to expect market forces to pry the Core out of Bitcoin. And as
@Roger_Murdock said in fact we should on the contrary be impressed by how much has already been accomplished with so little deadweight loss.
Our discussions here have made a great difference I think. Not that a fork wouldn't make more a difference, but then discussions here have laid the intellectual groundwork for such a fork, which many of us have propagated through other channels.
Here's how I see this actually playing out:
- Deadweight loss builds, including some forward-looking perception of loss (Fidelity Effect).
- Forks are tried at various stages, first getting little traction (XT; no deadweight loss yet, all anticipatory via Fidelity Effect), then getting substantial but perhaps insufficient traction (Classic; tiny but definite deadweight loss, greater anticipatory loss), and finally gaining sufficient and therefore soon overwhelming traction.
A spinoff is costless but will be ignored if too early. Whether it is better than a Classic-type fork attempt I can't say. They may be roughly equivalent in effect, because neither do much without majority uptake and both succeed if they have majority uptake (assuming 51% is enough to convince 75% to go along, which I think it is). However the spinoff method might be preferred because allows Core diehards to play in their own pool if they wish while the rest of the economy leaves them behind. (This dynamic doesn't work in reverse, because pressure to fork away from Core due to deadweight loss only *builds*, unless of course Core does somehow manage to come through with satisfactory solutions in time to stem the deadweight loss. We get to keep swinging until we hit a homerun, with circumstances getting better and better; meanwhile Blockstream must go all-in on one shot.)
