15:34:01 re: the spam attack, I think we should model out the dynamic fee adjuster so that it cools down much slower than it ramps up 15:34:16 argh not dynamic fee, dynamic block size limiter 15:34:43 like if it cooled down 4x slower than it speeds up then an attacker / abuser wouldn't be able to yoyo it to reduce their costs 15:38:01 IIRC ArticMine commented on this somewhere, but I can't find it now. 17:11:47 My question that I had thought of earlier today is: does the block size increase linearly? 17:11:48 If so, it should probably be changed to something more exponential, as the number of transactions happening follows trends exponentially more than linearly 17:15:07 preland: It depends on how much people are spending on transactions. High-fee txs make the block size increase faster. If everyone is paying the minimum fee (20 nanoneros/byte), then according to spackle's analysis the rate of increase is about f(x) = x^x. Very nonlinear. 17:15:54 Hmm 17:17:02 That's what we've seen on stressnet. I don't have an exact equation for what we've seen empirically on stressnet, but getting from the base of 300kb per block to 600KB takes a while. Then when we reach 5MB, it is quick to get to 6MB. 17:23:50 Fluffypony: I disagree. It should cool down very quickly like it does so that spikes (natural or otherwise) in tx volume are treated correctly: like spikes. The block size limiter should not stay high for temporary spikes as this opens the door to more abuse 17:24:44 I much prefer yoyoing to permanently large blocks 17:25:32 Also, yoyoing does not reduce cost for the attacker since the most expensive part of a spam attack is pushing the block reward into the penalty zone 18:58:27 * fluffypony ponders 19:34:36 "the long tail" is how i always thought of it. And the blocks wouldn't be permanently larger... sure, during a spam attack they might, but the blocks will only fill with transactions that are available. 19:34:51 and during a spam attack, it might allow normal users to get the experience they expect 19:35:36 spams gonna happen. to me its just a matter of how usable the network remains during the "spam"
