[XPM] The Unofficial Primecoin Overview Thread (all information in one place!)

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://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.

How to Use Vanitygen to create Vanity Primecoin Addresses and Paper Wallets: https://bitcointalk.org/index.php?topic=251850.msg2716295#msg2716295
Useful commands:
To have vanitygen create a Primecoin address: vanitygen -F compressed -X 23 A
For bulk-wallet usage, try this, which will generate 10 addresses: ./bulkwallet.sh 23 A 10 | ./paperwallet.sh >paperwallet.html
The View and print the resulting paper wallet in the browser of your choice.

*Please note, with any VPS, your account may be suspended since it may be considered abusive use. Leasing a dedicated server is the only safe way to avoid suspension but is much more costly.

Do you have AVX instruction set? Check using CPU-Z: http://www.cpuid.com/softwares/cpu-z.html
*Advice for optimizing v7.1: Don’t forget to press C after your auto tune has stabilized (after about 20 min). Pressing C will auto tune your L1 Cache. Write the results down and be sure to include that all other settings were on stock.

I applaud you :slight_smile:

Yup excellent thread :slight_smile: I have made this a sticky as well

Great Thread.

Is there a thread some where to ask more technical questions ???

[quote=“Excelsior”]Nice!

I do wish though, we had one for PPC as well. :D[/quote]

I had done one here a long time ago… tried to keep it somewhat updated

Just start a new thread I would say, you will find people reply or even Sunny King will reply if its a bit too technical for the rest of us :slight_smile:

Is it possible to send raw transactions with the primecoin daemon?

Hi,

I’ve just joined the community. I’ve read the wiki articles and functional white papers on primecoin. Please can someone point me any links/resources to understand the technical details of the protocol as in what does different lines of the primerecord mean. I’ve managed to dig out some of them but not all.

Also is there a means to submit new block records to the chain via the primecoin client.

Thanks,

Hi folks…

Could I just check, my peerunity qt works fine. My xpm qt worked fine for ages, but now shows the message ‘no block source available’, and has been this way for about 15 weeks. My peerunity is completely up to date, with about 8 active connections (as did the xpm until now)…and they are both running on the same computer.

Map port using UPnP is checked, proxy isn’t, in settings.

Can anyone help?

Cheers,

Roister01
