Bitcoin Forum

Hello fellow Primecoin miners.  If you are like me, you are confused by all the different miners, threads, clients and optimizations for Primecoin (XPM) now.  I figured we needed a post with all the aggregate information in one place.

Just as a very brief overview, Primecoin has a bunch of features (which admittedly, other alt-coins have) that are improvements over bitcoin.  The biggest one from a practical standpoint is much faster confirmation times due to 60 second block times (versus 10 minutes for Bitcoin).  This makes it functionally much faster for the  transmission of the primecoins.  However, what makes Primecoin unique from all the other coins (and there are a lot!) is its Proof of Work system actually does something useful (as opposed to a hashing algorithm such as SHA, scrypt, etc), it finds chains of prime numbers.

Specifically it finds the following types of prime chains:
1CC -> Cunningham chain of 1st kind
2CC -> Cunningham chain of 2nd kind
TWN -> bi-twin chain

What I really like about it, is these chains are useful not just for prime number theory but have uses for cryptography.  As we are all part of the crypto-currency revolution, anything that moves forward the science of cryptography enhances the entire eco-system.

For more information on what these chains are useful for:
http://en.wikipedia.org/wiki/Cunningham_chain
http://mathworld.wolfram.com/BitwinChain.html

To Summarize, the Upsides of Primecoin:
1. # of coins only limited by Moore's law and efficiency of algorithms to find prime number chains.
2. Fast transaction time
3. Proof of Work scientifically relevant
4. No pre-mine, fairly launched on July 7, 2013 at 18:00 UTC

Primecoin Downsides:
1. Since only limit is Moore's law (no set max coin limit), if Moore's law is broken (ie quantum computers), the difficulty may drop in the future.
2. If another more useful PoW is found which meets the criteria of being both
   a. Hard to compute
   b. Easy to verify
   Then interest in the coin will collapse along with it's value
3. If the coin is successful and prime number theorists can use the results to find an equation to predict prime #s, it would essentially break the coin's PoW.  Though, not everyone would view this as a downside due to the enormous scientific value that may provide.

Great All At One Place - Thread.

I am open to additions.  Let me know what else should be added or updated

thank you for this!

Added the primecoin wiki

Added the primecoin blockchain explorer

Thank you very much!!  ;D

It's very useful

Cheers! Mind adding this thread too? 
[XPM] CUDA enabled qt client miner for primecoins. Source code inside. WIP (https://bitcointalk.org/index.php?topic=258982.0)

great 3ad! It rocks

very nice thread, thank you for the compilation :)

great work,thx

Very useful.  Thanks!

+1 ;)

let's make this coin succeed! we need an agenda primecoin.

Thanks, made correction

Thanks for the info.

Will mining with the HP8 (high performance) client work in pools? I just see the notation that it is preferred for solo mining.

If it will work for pools, is it better than jhprimeminer?

The issue is currently there is only 1 primecoin miner pool and that is ypool.net.  hp8 can be used to pool mine if you had a pool to point it at. However, that would require a pool with either getwork or Stratum support.  Currently, ypool.net supports only pushthrough and therefore you can only use the jhPrimeminer with it.  On the bright side, the latest version came out today of jhprimeminer v0.34 beta and includes all the hp8 algorithm changes.

Added block crawler link

Oh wow that's great. So basically with the new version of jhprimeminer, we can now mine at ypool with our higher PPS rate. Do I have this right?

Secondly, where do I get the new version of jhprimeminer?

Just added links to two optimized hacked versions of jhPrimemienr by cabin and mumu.

mechs: is the 0.34beta version of jhprimeminer now as fast as HP8 now that jhprimeminer has those algorithm changes?

I would say yes, though the mumus version would seem to be faster than HP8 or v0.34

The mumus version gives me 29000 PPS on ONE of my cpus alone. That is greater than the total of all 4 of my CPUs with HP8. Is this correct??

There is now a fixed official v0.35 out, though I will stick with mumus for now.  PPS is not everything and mumus takes a while to experiment and find the best settings for your cpu.  The value of the shares produces is the most important thing, not the quantity.

Amazing, makes me realize how many xpm threads i was keeping up with. Thanks

PPS does not reflect your ability to find a block. At all.
Thus, the huge increase in pps sounds a tad fishy.

And anyway, it increased for everyone in the pool.
You went x10, but all your co-miners too, so...  :D

Amazing work! Thanks!

Glad to help!

How many coins reward is it for finding a primecoin block currently?

This is a good point. I also think it is fishy that it shows 10x the PPS. In fact, the actual payout to me in the pool stayed the same, despite the hugely increased PPS & shares. It doesn't seem to really have boosted my results. I don't understand how I can have more shares and pps and not more XPM payout though... What's going on here?

I am earning xpm much faster though in ypool with mumus.  Better than the official build

yeah mumus is the best for me on ypool too

Is there a 32 bit version of jhPrimeminer (mumus' high performance version 3.0)?

Or source code?

Some updates:
jhPrimeminer updated to v.035 (original had bug)
Added another GPU Miner thread (a working alpha, though not working well!)
A second blockchain explorer
Updated fees on the exchanges
XPM Prices crashing, world ending!

This was needed! Good work! Maybe some editing and use of B, colors and bigger fonts would help and make it easier to read  ;)

I'll work on that!

Added link to new version 4 of jhPrimeminer (about 25% faster) and a couple new threads of interest

Yeah sure do, some better formating and such, will make it much more interesting.

I will introduce this post to Chinese XPM fans.
Great work!

I would say amazing work. Keep it up!

Added link to the new v5.0 of mumus' version of jhPrimeminer

this. Is. AWESOME, just what I needed alongside my coffee.  XPM has my vote for long term, although I'm not personally in it for financial gain, but simply because they've done something to deserve it. the amount of power used in the United States to mine each day is upwards of 80k.  For useless work outside of getting coin. I'm prefer my power going to some other greater good besides finding block chains. t also makes me think we need to get on some wind power or solar power or something, cuz jeez that's a lot o money over a year in mostly wasted energy. (Unless you're heating your house with a rig ;) )

Updated with link to Dirk Augustin's Cunningham Chain World Records list where primecoin is cleaning up.  Anyone know where to find the records list for twin chain?

http://www.primenumbers.net/Henri/fr-us/BiTwinRec.htm (http://www.primenumbers.net/Henri/fr-us/BiTwinRec.htm)

heres one.

Thanks.  Someone needs to contact the record keeper and inform them about primecoin.

Agreed.

Info Ive been looking for is:

Number of total coins (seen in OP)
Block solve time
Reward per block
Does the reward drop after XX blocks?

No max coins, though the amount of coins awarded slowly decrease with difficulty increases.  At some point though unless ASICs for primecoin are developed, existing processors will take a long time to solve the increasingly difficult prime chains. 

Block solve time is variable, not fixed. Depends on when someone solves the current block.  The block refresh time though is 1 minute so transmissions move quickly.

Currently it is about 12 XPM, it is slowly decreasing.

It drops by a fractional amount constantly.  Not sure of the equation, I think it is based though on k (chain length)

payout = 999/(diff^2)

Where did you find the equation?  The white paper?

Yes - and it has also been quoted probably ten or more times in the announcement thread and the high performance thread.

Thank you, I'll update the posting.

Updated info on hp8 and mumusminer

Ty I will update that and version hp9 of the high performance solo miner

We host a Mac OS X build  ( http://dls.21stcenturymoneytalk.org/dls/primecoin/Primecoin-Qt-osx.zip )

A thread about it can be found @ ( http://www.ppcointalk.org/index.php?topic=343.msg2198 )

What happened the the GPU miner for xpm by mltrt? It looks like the thread was deleted. Did it turn out to be a scam/no product?

That is a very good question - he did collect about 60 BTC of donations towards it.  I would be surprised if he scammer people though since he a well known user here.  Though personally, I am sorta happy this has remained a CPU only coin. 

Me too. I'd rather keep making some XPM on my cpu for a while before it goes GPU-mainstream. Although I'm already noticing my mining resutls are dropping considerably.

Closed and created anew: https://bitcointalk.org/index.php?topic=273637.0

Made some updates - let me know if I should add anything else

And closed again due to whiners.  I'm sure he is still working on it, he's just not dealing with the drama on here. 

If anyone thinks anything should be added to the OP post, please let me know!

There is a native linux build for jhprimeminer that does not require wine. (complied on opensuse) ..I saw it in the jhprimeminer thread somewhere. You can add that.

Made many updates based on information posted in the maco's primecoin faucet thread: https://bitcointalk.org/index.php?topic=265191.0
Made the posting easier to read with bolding, underling and italics

Could not find it - can you provide link?

made some error corrections

Thanks for your updates on the thread and keeping the information relevant.

When will there be another pool to mine at for competition?

Good question - making mining pools not easy for primecoin as other alt-coin clones.

Updated with link to rdebourbon's updated version of jhPrimeminer (Mumu's version 7.1).  No idea if it really better though

Added cabin's latest x64  build of jhPrimeminer: https://www.dropbox.com/s/szayx15skhevv7x/jhPrimeminer.zip

Added the following:
jhPrimeminer Beta v3.1 (rdebourbon's latest update to v7.1 - some claim better performance)
https://www.dropbox.com/sh/sq24hzo993afy9c/l7icP0KiuM (x64 windows binaries)
https://github.com/rdebourbon/jhPrimeminer (source)

I have to say, this miner seems to perform better than v7.1 even without the avx

Have you tweaked anything yet or still running on default settings?

Well I use the  "-tune true" parameter for auto-tuning and then a press "C" after the first 20 minutes to also auto-optimize the L1 cache size.  Beyond that, I do not make any other changes

Added the newest exchange for XPM CoinEX @ https://coinex.pw/ .  Fee is 0% for now.  This makes the 6th exchange XPM is on.

Very nice  :)

too bad that btc-e petition seems to be going nowhere

Nice thread !

But regarding ramnode it should be edited. Here is what they replied to me when I asked them a while ago what was their attitude regarding primecoin mining :

Hi *****,

Please refer to our acceptable usage policy -- https://clientarea.ramnode.com/aup.php

Regards,

Elliot S.
Skype: RamNode
Twitter: @RamNode

the TOS is clear :

"HARDWARE RESOURCE USAGE

Client agrees not to run any processes on his or her VPS which create a CPU load above .9 on the VPS for an extended period of time or which cause a high CPU load on the host node for an extended period of time. In other words, client agrees not to use the equivalent of a full core for him or herself for an extended period of time."

Mining there will get your account suspended...

Thanks will remove it.  I have a feeling all the VPS might eventually suspend you unless you get a dedicated server since it "steals" resources from other users on the same server.

Linode kicked me out  :P

The best bet may be a less popular company since they probably kick people off when other users complain their droplets slow.  Less users means less likely for someone to complain.

There are 100s of us here ...we can just pool together and rent out some small VPS  companies.

Only two choices - keep signing up for VPS and milking them until account frozen or pay up for a dedicated server.  THe first method more time-consuming but also more profitable.  Dedicated servers expensive.

You can't milk VPS, they will cut you almost instantly !  Sometimes I could not even finish downloading the blockchain and was already suspended...

You can buy a server off ebay for example. There are cheap ones but you need to choose well and have space for them as they are known to be noisy and generate heat.

anyone offering their home servers for contracts?  ;D

I can offer a Pentium IV  :D

Why the GetWork protocol not implemented in XPM? Is it hard to achieve?

I have been looking into bulk buying dedicated servers, however, to get the full discount you need to hire them for a full 1 year  :(

Without the full discount I can get a Xeon E3-1230v2 (4 core @ 3.3GHz - turbo at 3.7GHz) , 16GB for $80 each per month if we bulk buy. If you can keep it a full 1 year then get a 10% rebate at the end.

I have one of these running at the moment and get between 1.1 and 1.2 chains per day.

With the current difficulty I put this down as breakeven at best so not really worth the investment.

Anyone got anything cheaper or more cost effective?

Of course, but no one will tell you :)

I will though, at this price you are better taking EC2 spot instances !

Spot prices are good, but even the cheapest is not profitable now.  Expect about a break even at best.

True, but it's still cheaper than the server he's renting !

Now the fact is that difficulty has stabilized so people keep on mining. The horrible ypool gets 20% of the blocks, where are mining the others for profit ?
Are they all desktop computers or are we missing the right vps providers ? I've been wondering about that quite a lot lately...

There's a fair number of normal home users who have a handful of desktops, then there are a few people with massive server farms, either through work or that they own themselves (think 100-1000 machines).  I think that makes up the lions share.  Some people bought VPS's on monthly plans and are still running them (probably already paid for), but dont know how profitable they are anymore. 

Some minor updates re: rd's miner - the new beta v3.1 seems to work better with AVX than mumu's for me
https://www.dropbox.com/sh/sq24hzo993afy9c/l7icP0KiuM

Added a 7th exchange (https://bter.com/) for trading XPM.

Compliments on the great concept behind Primecoin!!

It must be very popular now, its taking 2 hours and counting to sync :)
Hope there are a few coins left for me to mine.

We still in the early innings with primecoin, no worries there!

The coins are here alright, but getting them is a hell of a lot harder than it was a month ago !

How many XMP would a stock i7-2600k mine in a day at today's difficulty?

Well I have 176 cores going right now and am only finding a few blocks a day.

Some minor additions to the sites and formattings

It very variable but I think 2 days you'll get a block with hp10, but it soooo variable.

How about pool mining?

Added 8th XPM exchange: https://btcltc.com/

Nice, keep updating the post!

Feel free to let me know if there anything else worth adding

Added some locations to spend your XPM

Added information regarding a new XPM Pool.  Now we finally have an end to the ypool monopoly!

http://www.beeeeer.org (http://www.beeeeer.org)
Pool Fee: 1%
Protocol: getwork
Notes: Can use reference client, the high performance (mikaelh) variants or jhPrimeminer
Custom Client for beeeer.org (based on mikaelh's hp10 variant)
windows binary: http://www.mediafire.com/download/6y84jl1jdn5e9x8/primeminer_v01.zip (http://www.mediafire.com/download/6y84jl1jdn5e9x8/primeminer_v01.zip)
Source: https://github.com/thbaumbach/primecoin (https://github.com/thbaumbach/primecoin)

can explain how to use this pool? how to register or -poolsure=address ? how to see statistics?

Added more locations to spend your xpm

hi,

u dont need to register

you use your XPM adress as "user"

windows:
primeminer.exe -poolip=beeeeer.org -pooluser=<XPM adress> -poolpassword=0 -genproclimit=5

http://www.beeeeer.org/user/<XPM adress>
to see your stats

genproclimit= what best setting for xeon e1230 ?

i think the number of your threads = 8
if your cpu-usage is not 100% with this setting, set it to 9.

In statistics i see only
{
 "6": 7,
 "-6": 1
}

"6" = 6er chains ... u have 7 accepted 6-chains
"-6": 1 ... u have one stale.

rejected/stalerate should be 1%

someone can post link to windows binary compiled from this version of wallet?

It is in the OP

64bit or 32bit?

xolokram aka beeeeer.org-admin here  :)

hi

i just wanted to say that the pool is currently in testing-(you can call it beta)-phase.
i will try to find every bug/problem ASAP (i have a real life, remember that before stiring up the audience) ::)

glhf

ps. client is 32bit

@mechs:
can you provide a link to the kind-of-official announcement in OP:
http://www.ppcointalk.org/index.php?topic=485.0 (http://www.ppcointalk.org/index.php?topic=485.0)

Please add the 1 Troy ounce .999 fine silver physical XPM I am selling to OP as well as my shop which accepts XPM - finitebydesign.com

Here is a link to the physical XPM sales thread:
https://bitcointalk.org/index.php?topic=278474.0

updated OP with link to excellent primecoin article, link to beeeer.org annoucement thread and an additional XPM shop

some minor formatting fixes

Added Tandy's build of jhPrimerminer with all -hp10 optimizations for Linux (confirmed to work well on Ubuntu)
https://github.com/tandyuk/jhPrimeminer

Anyone try out the new beeeeer.org pool?  Any opinions versus ypool?

I am still on ypool using rd's variant 3.2 beta.  Let me know how the new pool works please!

i use beeeeer.org as well!

20-30k shares per block .... ypool = 500k
and better payout system @ beeeeer.org

block #11 now

I'll have to check it out!

Added a 9th XPM exchange: https://phenixex.com/

The CCE3 test explorer has been moved to:

http://cryptocoinexplorer4.com:2001/

I had to move the test explorers to their own server to begin testing the new server environment. I cannot do this on current live coin servers.

The test explorer is now at test version 3.5, and the extra features are to be added in test version 4.

Once the sever environment basic testing is done and is ready for public testing , the explorer permanent address will follow the CCE address pattern (xpm.cryptocoinexplorer.com)

 

Once it at the permanent address, let me know and I'll add it to the op

I have started testing the new server environment.

As a result the test Primecoin Explorer(and eventually the release explorer)

Has moved to its permanent address:


xpm.cryptocoinexplorer.com (http://xpm.cryptocoinexplorer.com)

or

www.xpm.cryptocoinexplorer.com

Very nice explorer!  I updated the OP.

Are there ways to earn this coin without mining, maybe by writing?

What do you mean?

I am also willing to share links and make YouTube videos or anything else.

Anything bloggy that can help the coin.
Ex: Devcoin has a whole wiki site that pays the authors, while at the same time bringing new users to Devcoin.

This coin was launched without any pre-mine, insta-mine and completely fairly.  As a result, there is no stash of coins held by the devs for a bounty.

So was Bitcoin, and I can earn them for chatting.

That is something Tradefortress has funded out of his own pocket largely to promote his eco-system of Inputs.io and Coinlenders.

That's great. Just wondering if you guys had anything of the sort. Devcoin pays for writing and today I learned that so does sex coin.

Updated pool info

Minor updates - let me know if any suggestions!

Any reviews on beeer.org versus ypool.net?

Added primecoin mining wiki and where to buy physical silver primecoins

Hm.... I got 60 Amazon EC2 cc2.8xlarge instances (don't ask, don't tell), i.e. 32x60 =  1920 cores to play with. I ran one 24 hour test with ypool.net, using rdebourbon's v3.3 for x64 Linux. It gave me about 140 XPM.

I since then switched over all instances over to beeeeer.org, using primecoin-hp 0.6 RC1 x64 for Linux. I'm around 8 hours into staring at this now:


As can be seen, not one single block found (I got around 1/hr at ypool.net), only tiny, tiny shares and not a single payout -- yet. Should I worry?

What's the problem?!

Just wait? Please give me one good reason not to switch everything back to ypool

Official Thread: https://bitcointalk.org/index.php?topic=305956

Why am I getting malware warning when I visit primecoin.org?  ???

is there any chance for fast-GPU-miner in the nearest future?

If you mean a miner that will run at greater than 10x the speed of the current miners, then probably not.
If you mean a miner that will run fast on a GPU, and doesn't need a powerful CPU [as the Bitcoin GPU clients were], then probably not.
If you are willing to pay for both a high-end graphics card and CPU, then a modest improvement may be achievable.
Time-frame? Unknowable.

also getting this...

More to the point, why on earth are you using a pool at all?  With this many instances you will have far better rewards by solo mining (believe me!).  Also, if you have a choice in which instance types you use, the 32 core ones are not the best value for money.  The miner is choked by L1 cache so actually performs no better than using 16 cores (try limiting the miner to 16 threads and you'll see virtually no change in performance).  The best instance type value for money is the c1.xlarge 8 core.  Take that from someone who has spent many thousands of dollars running aws instances XPM mining at up to 500 instances a day!   

Depends if you're running per hour or not.  I'm yet to see anywhere that can offer per-hour rates anywhere near as cheap as AWS spot prices if you want large numbers of instances.  But if you're looking for something to run for a whole month, then yes there are plenty of cheaper options

Great list and lots of useful resources in one place but one thing missing is how to set up private pool or am I missing it?

Currently not possible.  Nobody has released open source pool software for XPM, which is why there are only a handful of pools out.  The "work" for XPM can't be divided up in the same way as it can be for scrypt/sha-256 coins, so the share / payment strategies devised by XPM pools is markedly different.  Hence entirely new pool software needed to be written.  Unless you have a very large farm, you wouldn't benefit from a private pool anyway.  And if you did have a very large farm (in the 100's of machines) you would be better off solo mining anyway IMO.

Do you have recommendations on the best settings for each instance of VPS or a rig like how many core, mem, speed of PPS?

Have someone used VPS or dedicated servers for Primecoin mining?
If so, which service exactly did you use and how many chains/d did you get?

Hi,

As many of XPM mining pools listed here are no more running,
for now, you can have a try only with one of the two remaining Primecoin pool:

http://xpmforall.org/
http://pool-prime.net/

Thanks for update.

Fin you are the missing link * ;)  XPM rising again!!! 8)  weeeee
