I won't comment on CTV at this point, but these comments on BIP9 and BIP8
deserve a response, given the intense obfuscation below.
The only material distinction between BIP9 and BIP8 is that the latter may
activate without signaled support of hash power enforcement.
As unenforced soft forks are not "backward compatible" they produce a chain
split. It was for this reason alone that BIP8 never gained sufficient
support.
Taproot activation was in no way a compromise between enforced and
unenforced activation. Unenforced activation was wholly rejected.
> BIP 9 at this point represents developers attempting to disregard and
impose their will over community consensus, as well as an attempt to force a
miner veto backdoor/vulnerability on deployment. It should never be used
again."
This appears to be the start of another marketing campaign, an attempt to
reclaim Taproot activation as some sort of "win" over the "miner backdoor".
The same sort of misleading campaign was waged in the wake of segwit, and
led directly to the conflict around Taproot activation.
The differences between ST and BIP9 are inconsequential in this regard. The
criticism you are making of BIP9 above applies equally to ST.
> As with Taproot, any future deployments should use BIP 8 again
This is one of the most misleading statements I've seen here. It's not
technically a lie, because it states what "should" happen. But it is clearly
intended to lead people to believe that BIP8 was actually used ("again") -
it was not. ST was some technical tweaks to BIP9.
I am making no statement whatsoever on what "should" happen. My interest is
in providing accurate information so that people can make informed
decisions.
The outright deception around this one topic has led to significant
unnecessary conflict in the community. Make your argument, but make it
honestly.
