I agree with Mike Hearn that there is no consensus on using a soft fork to
deploy this feature. Either everyone agrees that we should all agree on
consensus or else there is arbitrary disagreement. You cannot have it both
ways.
It is very important that we reach consensus on consensus or, if you will,
meta0consensus. I think we should Do nothing as that is clearly the choice
that we have taken re: blocksize. If we use one set of rules for that
decision we should use the same set of rules for all decisions and there is
no middle ground.
Thank you.

📝 Original message:Adam,
While greatly appreciating your prior efforts in crypto-ccy R&D and
current efforts for Blockstream, its not a plus for your reputation to be
using emotive terms like ³attack², ³fork war" and throwing so much FUD
into the developer email channel directly after Eric¹s email.
We would appreciate seeing your well-argued thoughts, not FUD and flaming.
There are multitudes of trolls in all forums already.

Hmmm. What should be the price of an email? How much should DARPA have
charged for using TCP/IP?
I see a lot of well-paid, first-world technologists arguing for commercial
returns on a nacent protocol which could could offer benefits to the
unbanked.
Is that really the vision: to (re)build a de-centralized Paypal with
slightly cheaper fees and cool hooks into off-chain commercial systems
providing profits for the already rich?

📝 Original message:Benjamin,
Timeframe for network congestion and users experiencing service
degradation => between now and middle of next year.
Timeframe for transaction fees topping block reward fees => many years in
the future, based on current ratio of block reward to fees.
What is the more pressing requirement now? A working ³fee market² or a
reliable, useful payment network that scales without falling over in the
next 2-3 years.
