Pieter,
I think that you have misrepresented Chris' view by taking it out of
context. His complete quote reads "If drivechains are successful they
should be viewed as the way we scale -- not hard forking the protocol."
Chris is comparing Drivechains/sidechains to a hard fork.
You went on to "disagree", but every point of contention you introduced
was something that would apply to both drivechain-sourced capacity and
hardfork-sourced capacity. Neither improves scalability, and both allow
users only the opportunity to select a different security model. If I
understand you, the point at which a security model does not become
"interesting" to you, would be the exact same point in the drivechain
and hardfork worlds. Both, at any rate, have the same effect on
"validation cost to auditors".
The only true difference is the "extra risk of miners being able to vote
to steal your money", but as I have pointed out on this mailing list
several times, I do not actually believe that there is any marginal risk
-- miners can already "vote to steal your money" in the double-spend and
ln-channel-theft contexts. I have also argued that the "risk" is
actually desirable in an opt-in context, because it puts the burden of
proof on miners/developers (to convince users that they should move over
to the sidechain). Since their sidechain coins cannot appreciate in
value relative to the mainchain coins, users would only opt-in if they
felt that they were sufficiently compensated for any and all risks.
Hence, it is difficult to list this item as a drawback when, to the
user, it is a strict improvement (at least, by any epistemological
standard that I can think of). If you have new objections to these
claims, I'm sure we would all benefit from hearing them, myself most of all.
Paul
