Ok so we've had to scramble a bit as I don't think anyone except perhaps Jeremy
thought that there would be a Speedy Trial signaling period for a CTV soft fork
planned to start on May 5th [1]. That is two weeks away.
(I have to take what he says at face value. I can understand why one would be
skeptical.)
Understandably this has angered and surprised a few people including some of
those who have voiced opposition to a CTV soft fork activation being attempted
in the first place [2].
As I've said in a previous post [3] the Bitcoin Core 23.0 release candidate
(and older versions) does not include any CTV code or CTV activation code. If a
miner runs Bitcoin Core 23.0 out the box it will not signal for CTV. If by some
chance CTV was to activate through some other software release Bitcoin Core
releases would not apply CTV rules but they also wouldn't reject blocks that
apply CTV rules. Hence it is prudent to prepare for an eventuality where the
miner signaling threshold might be reached but the community wants to prevent
the attempted soft fork from activating. (I personally don't think a 90 percent
miner signaling threshold will be reached but I wouldn't want to bet Bitcoin's
future on it.)
I've tentatively labelled this effort a User Resisted Soft Fork (URSF) but I'm
open to better names. I certainly don't want to discourage those who dislike or
oppose UASFs from contributing to this effort and potentially ultimately
running a URSF release. If you don't want this rushed CTV soft fork to activate
we are all on the same side whatever we call it.
For now I've set up a ##ursf channel on Libera IRC to monitor developments and
discuss working on an additional release that if run may ultimately reject
blocks that signal for CTV.
The intention of this would be to provide additional direction and incentive to
miners that the community does not want this soft fork to be activated. To
repeat running a Bitcoin Core release will not signal for a CTV soft fork out
the box. If a miner runs a Bitcoin Core release it will not signal for CTV.
Apologies that this is rushed. But as always with Jeremy caution and
conservatism seems to be thrown out the window and we have to react to that. It
goes without saying that this is not how Bitcoin consensus changes should be
attempted.
