But I don't think we should be taking relatively new/untested ideas such as Drivechain and sticking them on a roadmap. There is a tendency in this community to hear about the latest and greatest idea and immediately fixate on it as our salvation. I'm very happy that you are doing this work and that others are researching a wide variety of ideas. But please, lets be conservative and flexible with how we evolve Bitcoin.

Hello,

Last week I posted about updating the Core Scalability Roadmap.

I'm not sure what the future of it is, given that it was concept NACK&#= 39;ed
by Greg Maxwell the author of the original roadmap, who said that he
regretted writing the first one.

Nonetheless, it was ACKed by everyone else that I heard from, except for Tom Zander (who objected that it should be a specific project document,
not a "Bitcoin" document -- I sortof agree and decided to label i= t a
"Core" document -- whether or not anything happens with that labe= l is up
to the community).

I therefore decided to:
1. Put the draft on GitHub [1]
2. Update it based on all of the week 1 feedback [2]
3. Add some spaces at the bottom for comments / expressions of interest [2]=

However, without interest from the maintainers of bitcoincore.org
(specifically these [3, 4] pages and similar) the document will probably be unable to gain traction.

Cheers,
Paul
