Timeline
--------
that's an important point. I've gotten that echoed from a few people
now. I was thinking that a re-submit could be called if more time is
needed but I think your method of allowing the author to have control
over the pace makes a lot of sense.
What does accepted mean? "Accepted" is the hardest thing to grasp in
this paper. There's just no way to force client authors, users, and
miners, to integrate and use a change, even if one is accepted by my
process. I.e. I'm trying to define what "accepted" even means, but
maybe I should use different words that don't have baggage. Like my
process could indicate "community greenlight" and client authors who
refuse to follow "community greenlight" can do so, but they are going
against the wishes of the community and that becomes obvious. Other
client others (like btcd) might follow the greenlight recommendation
instead and users are free to switch to that. Then there could also be
"community redlight", and "no decision reached" in which there was
conflicting views.
If I go this route, I could use the word "accepted" to mean something
like "appears in the longest fork", or "is in use by multiple clients,
merchants, & users" (for things like urls that aren't
blockchain-related).
How to prove stake?
--------------------
"How groups prove their stake" is the hard question that has to be
addressed in this proposal or any. I've pushed forward several
recommendations but there's no perfect solution that everyone will
accept. For users, in the comments I suggested a "community sample"
method that requires that only a random few people in a group to give
up their privacy.
Ratios
------
The "accepted" or "greenlit" standard in my proposal is defined as:
least 70% of the represented percentage stake in 3 out of the 4
Bitcoin segments. It's true that it seems weird to have 1 group in a
segment by itself (seems like too much power), you have to recall that
committees can consist of several groups that have agreed to act
together. If the 1 miner group had conflicts they'd separate to make
public both their views.
I'm interested in if you think that definition should be changed or if
you are worried about those risks.
