coinsmarkets.com does not support cryptonote.

All of a sudden no orders so very low pricing.

Manipulation!

Hi guys!
We have make another pool for MSR.

Lets spread hashrate.

Enjoy to mine tiwh us.

https://msr.dark-mine.su/ 0.25% fee.

the current DAA over 30 blocks (1 hour, not 2 - block maturity is 60 blocks) takes into account the median timespan (derived from Sumokoin) and not just the mean - many of the mined blocks are not in the screenshot you provided (mined from other pools) as we have a mining adversary with a private pool (hash rate is not observed in any of the public pools). This problem has gotten worse over time, and it seems like the adversary is trying to explicitly disincentivize miners with targeted attacks that take the algorithm into consideration.

The attacks have gotten worse since I mentioned (on Discord) that there is a new difficulty algorithm implemented that will replace this in our next protocol upgrade (though this could just be correlation and not necessarily the cause).
My initial plans were to include it with new features, which would place it near Q1, but it may be deemed necessary to push out the new DAA sooner.

Well, difficulty is supposed to "jump like mad" if the hashrate "jumps like mad" too. That's the goal, to mimic the hashrate, right?
It's only a problem when both jump out of sync 

The same situation was with sumokoin after 1-2 month since start. They had to urgently implement some mitigation to diff calculation code.

Masari's original DAA was much worse and after appr. six weeks it HF'd to implement the Sumokoin DAA. That's the one in use now since another six weeks or so. But it is still far from perfect as we see and it will likely be fixed in the next HF.

A couple of hours ago the nicehash idiot attacked again. Difficulty now over 200M and no block since two hours.

With the nicehash botnet for hire, new coins today need very quick and accurate DAAs. This wasn't the case three years ago.

People with large farms are not a problem. They are financially invested and act rationally.

But nicehash is another story. They provide every idiot who is not invested at all with a huge gun so he can go on a rampage and wreak havoc.

That would be pool-side and can't solve the problem. It could only contain it. I suggested that pools do not provide dedicated ports for the nicehash botnet. Masari.superpools provides even two dedicated nicehash ports.
But even if it didn't, someone could always create a private pool for nicehash and it happened already. The solution must be network-wide on the protocol level.
