Same here. Payments still "pending". Has anybody tried to get in touch with mmpool's admin?

I wouldn't mind throwing a yottahash at mmpool or two. However, how can we be sure that the mmpool admin still notices when we find a block?
Someone point me to some kind of proof-of-life of user "mmpool", please?

By the way, Namecoin has the highest hashrate of all the cryptocurrencies at the moment
(one of the side effects of the ongoing BTC vs. BCH mining pools hashrate battle),
see https://www.reddit.com/r/Namecoin/comments/7cge6l/namecoin_hashrate_is_now_higher_than_bitcoin/

Keep an eye on the current Delta value of the order. If it is higher than 2 % then you lose money because of frequently rejected bridges (caused by the Difficulty issue). In this case you better delete the order, and don't create new orders before mmpool finds a fix. Deleting an order automatically gets you a refund for the unused BTC amount of that order.

Don't worry about location. In the past I've found blocks for mmpool via both US as well as Europe orders.

Same problem here. Nicehash frequently change the starting and/or working difficulty, therefore:
@mmpool, is there a chance we get a parameter "initial difficulty" or similar? We need a solution for a reliable nh compatibility. On the other hand we don't want to exclude the small miners and hardware owners who need lower Difficulty values.
Alternatively, see philipma1957's idea (2 mining addresses).

Hmm, what makes you believe that I'll find another one just by running 10P for a few hours? I can try though. 0.2760 is indeed lower than the current break-even price.

BTW, it seems the Difficulty problems are solved now. Even a small 0.05 order starts working instantly. 0.05 causes a lot of friction, though. Which is a result of nh's distribution algo, I think. 0.25 PH/s is probably the lowest hashrate that works efficiently.

P.S.: Still not one single mmpool block on the Namecoin blockchain in sight ... 

Looks like the fix has solved the main issue but there is still a minor incompatibility problem. nh frequently tries to establish additional bridges and occasionally fails to get it over the "min. working difficulty" of 65535. We still have to pay for the failed connections. According to the Order Details page the Delta value is between -1 % and -3 % all the time (Delta: "difference between measured pool speed and paying speed.")

Meanwhile I had opened a ticket at nh. The response was as follows:
... Minimal difficulty is enough so the order is alive, but as soon as it gets some miners, pool needs to reach working difficulty or above. If not, the order will be disconnected. We suggest to simply use pools that never use difficulty below 65536 and you will not have issues with that.

Furthermore, the Pool Verificator at https://old.nicehash.com/poolver.jsp?a=1&l=0
comes up with:

nh have changed the minimum difficulty to 2^14-1. That's why all the inactive or partially active orders are now marked as "Dead" most of the time, and nh deletes them after a while.
I already tried changing my username to "+32768". The mining pool's overall hashrate then looks correct but my hashrate is zero and the shares don't turn up in my statistics. What is the correct way of setting the initial difficulty?

Do not use namecoin-wallet.com! There is a very recent report of a victim of namecoin-wallet.com:
https://www.reddit.com/r/Namecoin/comments/6lhyj0/where_are_my_namecoins/
and there are a lot of similar stories here on bitcointalk.

Works like a charm, thanks.


Me too. Eagerly awaiting our first Namecoin block after a long while
BTW, Bitminter made one of its rare appearances on the Namecoin blockchain recently, block # 350105


I hope it was me (translates as: I desperately want this 1.7 btc bonus ). The strange thing is that this was the third time I found a block just hours (and this time just minutes) after I manually added a single large-scale order at nicehash. My mediocre maths understanding had assumed that there is no difference in luck between mining 8 hours at 1 Petahash/s and mining 1 hour at 8 Petahash/s. Wondering if anyone could point me in the right direction as to where i am missing a non-linear component in the equation?

This is great news. The NMC withdrawal issue is still there, though. 


This is the perfect opportunity to have a look at namecoind 0.14.99

I must admit I'm mildly skeptical about short-lived marketing campaigns for altcoins. Most of them fail because they seem to expect "immediate results", or call it "a quick buck".
If Alexoz has an elaborate idea how to attract long-term attention to Namecoin, though, then I'd say welcome to the team.

You need to be a more specific, I'm afraid.
The fact you wrote "slack" in lower-case indicates you are looking for a slack-desc file for Namecoin. If you have "Slack" in mind instead of "slack", however, then I could guess you're asking for a namecoin Slack channel, just like our Matrix/IRC channels #namecoin and #namecoin-dev. Or is it some Slack identity information you want to publish on the Namecoin blockchain in order to include a decentralization feature in Slack (similar to the Bitmessage client that is able to retrieve Bitmessage identity information from a Namecoin client)?

There are two issues at the moment:
(1) mmpool.org/statistics shows the wrong Difficulty value.
(2) Withdrawing NMC comes up with a "connect: null" message box.

There are nearly 10,000,000 name_new transactions on the blockchain. One single name_new tx burns 0.01 NMC. Therefore around 100,000 NMC have been burned.

Technically speaking these 100kNMC haven't been burned, they are just inaccessible. If we ever run out of NMCs because of a future large-scale usage of Namecoin we could do a hard fork and purge all the expired, abandoned, unused or erroneously issued name_new transactions. This would release those inaccessible NMCs to be reused. A hard fork requires the approval of the miners/mining pools, though.

The Namecoin github repo is the place for the most up-to-date info.

At times these sites also show some activity:
the Namecoin subreddit
the historic bitcointalk thread of Namecoin
and the Namecoin Forum, mostly in the General Discussion section.

Just started to read about Monero's PaymentID feature. I'm wondering if it is safe to mine to an address without a PaymentID? Kraken, for instance, doesn't give you a PaymentID whereas Poloniex does.

Actually, we are winners if we simply keep on hashing. There will be quite a few low-CDF blocks this year. The only ones who lose money are those who stop mining at this pool right now.


At the moment the prices at nh are unusually high for this time of day, anyway, therefore I'm currently close to 0 Th. As soon as prices get back to the break-even point or better I'll rent as much hash as possible without driving the price up to above the break-even threshold. I hope you'll do the same. As of Feb 18th around 11 a.m. UTC, however, (i.e. the next Difficulty change) our nh purchase activities should come to a temporary standstill for a day or two until all the other hashrate buyers start to notice the Diff adjustment. They tend to pay ridiculously high prices during the first few days.


You don't need to match anything/anybody. Within a mining pool there is no such thing as "competition". It is always "cooperation" no matter what the individual miners do (except maybe pool hopping etc., but that is not worth the effort IMO).

Sorry about causing some stir here. Seems I need to step forward and end the guesswork. After earning considerably more than I had spent on rental costs in 2016 (due to luck) I had thought it's a good idea to give something in return and support this pool by throwing in a petahash or two for a while. Now that we are experiencing a 80+% CDF round (due to bad luck) I can't stop mining here because of Gambler's Fallacy, oops, mathematical statistics. The main reason I don't do solo mining is, however, I'm not sure I'd get the node connections right in order to reduce the orphan risk to a minimum. mmpool has got plenty of experience with this aspect of mining operations, I assume. Furthermore, I might be able to motivate mmpool to resume merged-mining Namecoin. It's called "mm"pool after all ;-)

This is the result of the both of us purchase hashpower mostly at Nicehash. Between noon and midnight UTC the price at Nicehash usually rises way above rentability, therefore both your and my orders at Nicehash tend to freeze. As of midnight UTC our orders wake up due to low demand i.e. prices getting back to the rentability zone. Maybe it's a good idea we coordinate our orders at nh?

Just in case anybody thinks that I "steal" DGM value from other miners should take a closer look at the DGM maths. Simplified speaking, the more hashpower I throw at this pool the more likely it is we find a block within a reasonable period of time.
