That might be your impression, then you've misunderstood what I
intended-- What I wrote was carefully constructed as a personal view
of how things might work out. It never claimed to be a a project
roadmap. Though as usual, I work hard to propose things that I believe
will be successful... and people are free to adopt what they want.
And to the extent that it got taken that way I think it was an error
and that it has harmed progress in our community; and created more
confusion about control vs collaboration.
With perfect hindsight I wouldn't have posted it; especially since
we've learned that the demand for increased capacity from many people
was potentially less than completely earnest. (The whole, can't double
capacity until we quadruple it thing...)

I don't agree that you have; but for the purpose of this thread
doesn't really matter if I (specifically) do or don't agree. It's an
objective truth that many people do not yet believe these concerns
have been addressed.

That Adam asked me to write publish a new "roadmap" for Bitcoin as
you've done here, with particular features and descriptions, which I
declined; and explained why I didn't believe that was the right
approach. And Adam worked with you on the document, and provided
content for it (which I then recognized in the post).
Set aside what you know to be true for a moment and consider how this
might look to an outsider who found out about it. It could look a
like Blockstream was trying to influence the direction of Bitcoin by
laundering proposals through an apparently unaffiliated third party.
Doubly so considering who participated in your drafting and who didn't
I don't think in actuality you did anything remotely improper
(ill-advised, perhaps, since your goal to speak for developers but you
didn't speak to them, IMO--) but I think transparency is essential to
avoid any appearance of misconduct.

As Bryan pointed out... with the exception of the intro and end and a
couple sentences in the middle my entire response to your post, with
the position on "roadmaps" was written a long time ago, specifically
to complain about and argue against that particular approach.

I think you may be mistaking a roadmap with "communications"-- people
taking about research they are exploring is great! and we should have
more of it. But like with RedHat and kernel features, we can't really
roadmap things that are unresourced and currently just unimplemented
exploration or test code-- without seeing things which are more or
less done the community can't rightfully decide if they'd want to
support something or not. Perhaps they'll be good things perhaps
awful-- the devil is in the details, and until an effort is fairly
mature, you cannot see the details.
There have, for example, been signature aggregation proposals in the
past that required address reuse (could only aggregate if they're
reused). I would strongly oppose such a proposal, and I hope everyone
else here would too. So if I were a third party looking at your
message, rather than the person who initially proposed the agg sig
thing you're talking about, I wouldn't know if I could love it or hate
it yet; and probably couldn't be expected to have much of an opinion
on it until there is a BIP and/or example implementation.
To the extent that a roadmap differs from communications in general,
it is in that it also implies things that none of us can promise
except for our own efforts; Completion of implementations, success of
experiments, adoption-- basically assuming a level of top down control
that doesn't exist in a wide public collaboration.
One of the great challenges in our industry is that we don't have
rings of communication: We don't have much in the way of semi-experts
to communicate to semi-semi-experts to communicate to media pundits to
communicate to the unwashed masses-- at each level closing the
inferential gap and explaining things in terms the audience
understands. We don't have things like LWN. We'll get there, but it
it took the Linux world decades to build to what it has now. I think
various forces in the industry work against us-- e.g. we lose a mot of
mid tier technical people to the allure of striking it rich printing
money in their own altcoins.
It might be attractive to try to end-run the slow development
appropriate web of reliable communications by deploying high authority
edicts, but it ultimately can't work because it doesn't map to how
things are accomplished, not in true collaborative open source, and
certainly not in an effort whos value comes substantially from
decentralization. Doing so, I fear, creates a false understanding of
(It's a common misunderstanding, for example, that people do what I
want (for example); but in reality, I just try to avoid wasting my
time advocating things that I don't think other people are already
going to do; :) otherwise, if _I_ want something done I've got to do
it myself or horse trade for it, just like anyone else.)
One of the great things about general communications is anyone can do
it. Of course, unless they're talking about their own work, they
can't promise any of it will be completely-- but that is always true.
If someone wants some guarantee about work, they have to be willing
to get it done themselves (and, of course, if it's a consensus
feature-- that much is necessary, but still not sufficient to get a

Come now, this is needlessly insulting. I would have made the same
comment if you had talked to me because you didn't talk to most/all of
Matt Corallo, Wladimir, Pieter Wuille, Alex Morcos, etc.... e.g. the
people doing most of the work of actually building the system. Before
making that comment I went and checked with people to find out if only
I was left out. Talking to Adam (who isn't involved in the project)
and Luke-jr (who is but is well known for frustratingly extreme
minority positions and also contracts for Blockstream sometimes) isn't
a great approach for the stated goal of speaking for developers!
