MasterPool started as a Namecoin Pool but was the first pool who implemented merged-mining (http://dot-bit.org/Merged_Mining).

The pool at a glance:

  • first merged mining pool (and the only one who also was tested publicly on testnet so far)
  • PPLNS payouts of block rewards including its transaction fees
  • no mining fee substracted instead you pay a payout fee
  • scheduled payouts each night (with 1% fee)
  • instant payouts (with 2% fee)
  • redundant master servers located in east and south germany
  • email notifications
  • micro forum for feedback, suggestions and small talk
  • JSON stats for website and your miners

If you want to have a look at the pool I'd suggest to start on our statistics page: https://www.masterpool.eu/statistics. There you'll find a countdown for merged mining, too. If you want to start mining right away please join at: https://www.masterpool.eu/signup.

Due to the possibly upcoming attack of BitcoinEXpress ( http://bit.ly/poTuzs ) MasterPool will start validating NMC blocks beginning with the next round until further notice. The current block will still be paid out directly.

Dear MasterPool user


you are getting this email because you registered on MasterPool. I'd like to inform you about a severe issue on namecoin blockchain.

Due to the upcoming 51% attack to the namecoin network as outlined on the forums [1][2] MasterPool can not guarantee the safety of your namecoins. In fact if BitcoinEXpress will succeed with his attack and resets the blockchain to block 10000 all blocks ever mined on MasterPool will be undone. This is not only a problem with MasterPool but with all exchanges and pools. The attack is scheduled for block 19100.

At the moment the community is trying to mount countermeasures but it is still unclear if we get enough hashing power to counter this attack. So if you are unsure about what to do and want to be on the safe side it might be the best to withdraw all your namecoins from MasterPool, stop your namecoind, backup your wallet.dat AND your blockchain and wait for the storm to pass.

Your other option is to not withdraw your namecoins from MasterPool. However I CAN NOT guarantee for their safety. Thus you take the risk of loosing ALL your namecoins. I will however do my best to keep them safe. But if the blockchain is reset to block 10k they are gone anyway :-(

MasterPool will stay up during the time of attack. And we'll try to start merged mining on block 19200. If you are brave enough and want to help overcome this issue please consider to put all your available hashing power onto the namecoin blockchain. At the moment this seems to be the only possibility to effectively counter the attack. If you want to help secure the namecoin blockchain please register on at least one other pool to make sure you have an alternative if MasterPool is forced offline during this attack for any reason. Other namecoin pools are for example:

* DoubleC's Namecoin pool: http://bitparking.com/pool
* Davincij15's pool      : http://www.nmcbit.com/

Due to the attack Davincij15 offers a very competitive payment of 0.00003030 BTC (yes correct: bitcoins!) per namecoin share [3]. Thus if you are mining BTC in pay per share mode you might want to consider this offer in order to strengthen the namecoin network and get a bunch of bitcoins. Please tell your friends as well!


Happy mining!

hi nodemaster,

i really like your pool. it's one of the fastest right now (0.02% stales constant is very good!).

but please consider another payout system (or make a vote).

i do prefer *PPS - but only reason is that i dont like the idea of some shares getting worthless.

Sorry for the way too late answer. But it seems I managed to disable notifications for this thread  Undecided I already answered you question regarding payout system some time ago via PM. If merged mining started succesfully and is stable for some time I'll let all users vote.

However (and IIRC this was not answered in PM) unfortunately I won't offer PPS. I know this is very popular demand but I'm not willing to take the risk. I'll provide a fully fledged and hopefully rock solid BTC pool, but the main intention is to strengthen the namecoin blockchain. As you might know NMC is not really a currency like bitcoin (at least not forever. However at the moment it seems like). It's ONLY there to "bootstrap" the naming system stuff and is destroyed over time (unlike bitcoins). Merged Mining and MasterPool is one thing to make sure name resolution and registering is still possible if all NMC are gone some day. However this will be at the time where the block reward is no longer existant at BTC network as well (or it is very low and the share is determined from the TX fees). At that time it will be very hard to estimate a PPS value. I know this is long time. But MasterPool is here to stay for long time and so is its design. BTW: This is the reason why MasterPool also distributes the TX fees among its miners as there will be a time where only transaction fees are left for distribution  Tongue

Thus I don't see any possibility for PPS  Sad

I disabled automatic merged mining activation as I don't want to start it without having an eye on it under this circumstances  Undecided I'll activate it by hand as soon as I got some sleep and the DDoS settles.

You deserve some sleep, but "waiting for a DDoS to settle" can take 1 hour, 1 week, or 1 eternity.
Don't rely on it to stop, be proactive.

Why the frell so many retards spell "ect" as an abbreviation of "Et Cetera"? "ETC", DAMMIT! http://en.wikipedia.org/wiki/Et_cetera

ATM it doesn't make any sense to mine on the pool. We have 80k+ incoming connections from a Botnet. Unfortunately I have no possibility at hand to filter the connections (as they are coming from several IP addresses). For that reason I'll shut down the mining ingress servers. Unfortunately this means you can not mine on MasterPool. But we need the hashing power on NMC blockchain and I just hope most miners have configured a fallback and will be switching to another pool.

MasterPool will be back as soon as the storm is over (and I got some sleep).

The complete roundup can be found on NMC Forum: http://dot-bit.org/forum/viewtopic.php?p=2110#p2110

Yeah, I guess I'll come up with something like slush implemented on his pool. It's really neat. Only allow connections from known users. But I'll do it later  Grin

Please update so that https://www.masterpool.eu/jsonstats shows statistics for BTC.  Currently shows only zeros.  Thanks.

Yes, thank you.  Unfortunately, I don't know enough Python/json api to differentiate between the NMC "shares" and BTC "shares".  Falling back to trial and error coding ...  Smiley Smiley Smiley

Here is a pretty neat tool for formatting JSON: http://jsonformatter.curiousconcept.com/ Just load https://masterpool.eu/jsonstats there. IMHO this makes it much easier to understand how to iterate through the data:


{
   "workers":79,
   "hashrate":"22.53",
   "blockchains":{
      "NMC":{
         "shares":"34803",
         "stales":1117,
         "roundduration":7489
      },
      "BTC":{
         "shares":"46267",
         "stales":1542,
         "roundduration":27818
      }
   },
   "updated":1318082048
}


In most programming languages there are functions to convert JSON into an array.

Have you tried EU01 instead? M8R still sieges the US server with his botnet. Getwork requests are very slow from time to time.
