yes it was lower, on the right chain, but nobody mined on it actually.
i don't know exactly how it works but looks like an attempt of 51,
first make pool look inoperable loading it with too much MH,
ppl cut off, then you're alone on the chain and can do what you want.
There is no evidence of such an attack from here, but as you say, we may have just been on nodes on the correct chain, so all looks ok except for the delay. If one of your nodes was a victim on a suspected incorrect chain, could you PM me the debug.log file so that I can verify what it looked like from there?
i can't, everything is cleaned already,
all i know is chain was stuck with low diff and no miners on correct chain,
then i've mined a block to unhook the thing, and 32 more declining diff to help jumpstart a pool
Again, if you have evidence and can provide a log of a solo mined client on a different chain, it would be most useful.
We've been watching carefully all day today and it's pretty obvious that someone is (actually 2-3 people it seems) just mining until difficulty goes high, dropping off, then waiting for the stuck block and for difficultly to go low again and then repeating. This is not an attack though, it's just playing with the block times and making them a bit erratic (i.e. some happen really quickly, some take a long time). Difficulty re-target is working though and the overall supply rate appears to be just fine (i.e. no more/less blocks than expected are being generated), just how long it takes to complete varies. This happens a lot in all coins, even Bitcoin, because it's fair game given how the network works.
This stuff is fun to watch :-P
I see a large network hashrate, and no blocks happening. Either there's another pool or solo mining operation that are 1) not connected to the main network and messing with things, or 2)
The large network hashrate is based on how many blocks are being found in some amount of time and there's no way that amount of hashrate can be reported without finding blocks. So something is weird. Admittedly, I don't know what it is either, but it's been interesting to watch.
And yes, I'm still working on the windows thing we discussed, but haven't been able to get back to it just yet. If you're ahead of me, go for the next release, but otherwise, I'll be in touch soon.
