    then if it goes down
    the next block will be low
    and the multi will jump on that one
    raising the next block, but leaving when that happens
    so the multi will get all the easy blocks
    and leave the hard blocks for everyone else.
    again, just guessing how targeting works
    also, how multis work
    the only thing that would work is creating some kind of way to make it impossible to jump in and out of mining
    if the point of mining is to make transactions work, then why not make the reward for mining the ability to do transactions
    then you don't have to artificially make mining any harder than it needs to be.

    still, I don't understand this, in effect.

    I don't know enough about targeting vs. multipool tactics to know what the right answer is
    I'll try to read about it, but I expect that every scheme will be susceptible to manipulation by big pools to some degree
    If I was really optimistic I would hope that there's a serious mathematical analysis of these targeting methods complete with bounds on how effective various pool tactics might be

    I do agree about moving to fixed block rewards, for what that's worth

    @ummjackson
    fixed block reward, there are a couple of PRs so we're getting there
    the difficulty retarget is the biggy

    hey just catching up on everything here, I forgot about this to be honest... I actually did a little work on an alternative difficulty algorithm when I was playing with a test coin I made. It was an exponential moving average I think, but I bailed on it at some point
    had concerns about floating point determinism because I'd recently run into a problem with that in a game I'm working on.
    FWIW I think dogecoin has a strong enough network that 90% of the problem could be addressed by changing the diff retarget interval to a smaller number. like 10? 20?

    @somegeekintn
    Interesting. Netcoin recently switched to KGW and I see this morning that the coin appears to be broken. Not sure it's related though.

    @alanmcintyre
    I think I would default to keeping the current simple algorithm with increased interval. The fancier the algorithm is, the more likely it has some weird dynamical behavior you never thought to check for.
    and somebody smarter will come along and do some clever variational calculus thing to find an exploit that makes small miners sad
    Alan McIntyre
    @alanmcintyre
    Can I be a wet blanket and ask if it would be better to just make the reward fixed and then re-evaluate whether the difficulty retargeting is still insufficient? Changing two behaviors--especially if we're going to come up with a new retargeting algorithm--seems fairly risky.
    But I don't know if the current feeling in the community is that both things must be changed "right now."
    At any rate, if I can help by running a testnet client or two, please post a message here and I'll be glad to.

    Well, for the community it has to be done yesterday and we should also integrate ethereum, scrypt-n, scrypt-jane, KGW and whatnot

    @langerhans
    I agree though that changing two things at once is not very representative in the outcome. but random block rewards is just for the "block gambling" problem
    Alan McIntyre
    @alanmcintyre
    yeah I definitely think random rewards should go away first

    @langerhans
    The multipool jumping problem is well known. I remember the Fedora community asking for help cause a Multipool jumped off them in mid diff cycle, leaving them with 5 times or so higher blocktimes.
    Alan McIntyre
    @alanmcintyre
    Yeah mooncoin was stuck with multi-day confirm times not too long ago because of that too
    although I think our base hash rate is high enough right now that we may not suffer as much from jumping
    Max K.
    @langerhans
    So I'd say tackling both problems in one fork is somewhat resonable. A fork is always risky. Better fuck up once than twice :D
    Alan McIntyre
    @alanmcintyre
    Just so the retargeting change is fairly simple and not some novel algorithm that nobody has tried before
    Max K.
    @langerhans
    Well, if we really go for 10 minute retarget... I don't know a coin (in our scale) who tried that before
    Alan McIntyre
    @alanmcintyre
    is that the current idea?
    Max K.
    @langerhans
    That's what's in testing currently
    Results seem to be promising
    Alan McIntyre
    @alanmcintyre
    Well at least the current PR is just changing the interval and not the algorithm, which seems fairly safe I suppose.
    Max K.
    @langerhans
    I don't know if they are still looking at other algos...
    voidref
    @voidref
    I wonder if there's a way to block known multis
    Alan McIntyre
    @alanmcintyre
    you mean try to block them from participating in mining?
    Max K.
    @langerhans
    we're currently testing DigiShield
    Alan McIntyre
    @alanmcintyre
    what's that?
    Max K.
    @langerhans
    DigiByte's super new diff retarget algo which seems to be proven multipool proof
    Alan McIntyre
    @alanmcintyre
    ah cool
