E.g. centos won't have support for it. 86 2015-12-11T08:54:42 <wumpus> what matters for gitian is what ubuntu versions support it, at least 14.04 does, but don't know if e.g. 12.04 does 87 2015-12-11T08:56:01 <wumpus> then again, as this is only used to communciate with a vm on the local host, may be good enough to just add the force-use-dss option. Heck, using no cipher and auth would probably be acceptable... 88 2015-12-11T08:57:22 <gmaxwell> or just set it to use 2kbit rsa, the generation time is probably not that bad on anything that can compile bitcoin. 89 2015-12-11T08:57:23 <wumpus> (using ssh to communicate with something running on localhost is kind of redundant :-) ) 90 2015-12-11T08:58:49 <wumpus> changing that would mean regenerating all the base images though 91 2015-12-11T09:03:29 <wumpus> Luke-Jr: if you change the ssh line in libexec/on-target to include -oHostKeyAlgorithms=+ssh-dss , does that work around the issue?

The earlier logic had a rate table where transactions were added in arrival order, with the required fee gradually going up as the non-fee-sorted candidate block became bigger. In 2012 it was changed to the sorting based selection on the basis that this was the rational behavior to miners, and the ' 228 2015-12-11T23:27:41 <gmaxwell> fullness' of a candidate block was pretty opaque to users. 229 2015-12-11T23:28:25 <gmaxwell> What the logic was was that up to half the target size, the ordinary fee behavior applied. above half the target the required fee was multiplied by target/(target-current). 230 2015-12-11T23:29:48 <gmaxwell> What we lost in that change is any backpressure at all, until the limit was met. The belief that this was good for miners was mistaken in any case, since fees relative to orphan impact are small. 231 2015-12-11T23:31:11 <gmaxwell> And then the need to constantly keep bumping the soft limit to avoid that cliff from the system being poorly stabalized also meant that blocks found fast would glup down a pile of spamflood. 232 2015-12-11T23:37:17 <gmaxwell> I think we've probably not given this enough thought due to paying too much attention to what short term rational miner behavior would be; when probably really optimizing miner behavior would already not be including most of the transactions today at current feerates. 233 2015-12-11T23:42:37 <zookolaptop> Right. Bounded rationality. I'm a businessman, and if there are two sources of revenue, one of which gives 100X what the other one gives, then I would tend to say "FUCK that other one! Don't bother me. Don't spend your time thinking about that other one.". 234 2015-12-11T23:43:08 <zookolaptop> 100X is correct, currently, right? 235 2015-12-11T23:45:15 *** raedah has joined #bitcoin-core-dev 236 2015-12-11T23:45:36 <zookolaptop> That's what I wrote on twitter the other day, on my way home from Hong Kong. https://twitter.com/zooko/status/674422815299231744 237 2015-12-11T23:55:07 *** droark has joined #bitcoin-core-dev 238 2015-12-11T23:56:58 <gmaxwell> The other thing is that the rational marginal feerate needed to add an attitional transaction to a block actually goes down at the block gets bigger; not up. 239 2015-12-11T23:58:10 <zookolaptop> Good point. 240 2015-12-11T23:58:33 <gmaxwell> This is because the possion distributions of blocks, has an exponential distribution of interblock intervals, which has a slope that decreases with more delay. Basically, if you're already screwed latency wise, the marginal harm of including another transaction is less.
