is this just a failur because the coin hasn't started yet?

Truly excited, I'm sure this coin can go places with an active and supportive dev as yourself gatra!

Keep up the good work and let me know if you need any help promoting.

Cheers!

I hope compiled versions for windows will be available at launch.

Yes, they'll be available. I'm having problems with some antivirus detecting it as malware because it's based on code from the cpuminer that may have been used for botnets (I even deleted the sha and scrypt mining code but they still complain).
But of course it's a false positive and executables will be available.

The external miner "cpuminer" (executable file is "rminerd" to differentiate from the original "minerd") requires the same libraries as Pooler's cpuminer (libcurl) plus gmp. To compila, you will need autotools too.

I hope compiled versions for windows will be available at launch.

Excited for this project! Any ballpark estimates for memory throughput requirements? How large of a sieve is used?

In the external miner, sieve size can be configured via command-line parameters but the default is 1Mb (per thread). I believe best results are achieved when the sieve fits in the processor's cache. But this will depend on your hardware...

That's interesting. But since we don't actually know whether there are infinitely many sextuplets (and certainly can't assume such sextuplets exist in a given range of values), doesn't that mean that it's possible to hit a difficulty with which no block will be possible to find?

It's not proven, but sextuplets are believed to be infinite. If we ran out of sextuplets I would be very happy because Riecoin would have served it's purpose of helping science! It would be an important result for mathematicians. And the coin wouldn't die because we could switch (hard fork) to prime septuplets or octuplets, etc.
We can't be sure such sextuplets exist, but it is conjectured that distance between sextuplets is O( (log p)^6 ) and the max distance between them is O( (log p)^7 ). An interesting article on this can be found here: http://arxiv.org/abs/1301.2242
This max distance (believed true but not proven) adds an interesting feature: in theory if you are very unlucky you could do sha256 hashes in Bitcoin style for years and still produce no blocks. But this maximum indicates that if you mine long enough then you will find a block: as long as k*(log p)^7 fits in the nonce filed, you could assume that there exists a nonce that produces a block. Bitcoin does not have a theoretic background that allows you to claim that. We do. It's only conjecture and not proven, but lots of mathematicians believe it to be true. I admit this is not very useful because not only you need to find it, you also need to find it before 2.5 minutes. But being (almost) sure that the nonce exists feels good.

Also, with pooled mining, since finding a quintuplet is O(logp) easier, that'd mean share value would need to adjust with the difficulty (since greater diff - bigger p - easier to find a quintuplet compared to a sextuplet). Which would be quite a nuisance (though I think XPM does that, it's still subject to readjustments on, for example, YPool).

It's true that share value has to be normalized for difficulty. But that's not a problem, since we have a formula for that. Moreover, the relative value of sextuplets to quintuplets, quadruplets or whatever the pool decides to accept, can be computed too using Hardy Littlewood k-tuple conjectures.
Ypool based relative scoring of XPM shares of different chain lengths based only on trial and error.

gatra which libraries are going to be needed for compiling? The same as bitcoin or do we need something else too?

Will we be able to solo mine with the client or are we going to need an external miner?

Quote from: Vaxa on February 08, 2014, 09:29:05 AM

Whether the cpu-miner (not wallet-miner) will be available during the launch?

The client/daemon require the same libraries as Bitcoin.

The qt client has an embedded miner, but it's slow, the external miner is recommended.

The external miner "cpuminer" (executable file is "rminerd" to differentiate from the original "minerd") requires the same libraries as Pooler's cpuminer (libcurl) plus gmp. To compila, you will need autotools too.

I just translated the launch post into Chinese as below:
https://bitcointalksearch.org/topic/annric-pow-feb-11-2014-454135
By the way, I registered this ID for protective purpose, and the domain http://riecoin.net too.
I will only use them to promote riecoin in China, and will be pleased to return them if necessary.
Finally, have been looking forward to this for quite a few months, and wish riecoin stand out.

Thank you for your effort!

Promotion is welcome!

I only ask you to please make it clear that users "riecoin" and "gatra" are 2 different persons.

Thanks and regards,

The explanation of Riecoin's proof-of-work algorithm is now published in riecoin.org

So this is the secret: prime sextuples. Each block represents six prime numbers of the form p, p+4, p+6, p+10, p+12, p+16.

If you expected just finding prime numbers, one per block, and you fill cheated, please try to understand this:
It's not practical to just look for prime numbers, because verification would be almost as hard as mining. So there has to be a catch. Something to make finding more difficult than verifying.
There are many ways to do this, for example requiring that the primes follow some arbitrary rule like they should be k1 mod k2. Or spell my name backwards, or whatever, but this would waste resources arbitrarily discarding primes that don't fit, and it doesn't make the accepted primes more interesting mathematically speaking.
Requiring sextuplets make it harder to mine while still keeping interesting properties regarding the distribution of prime numbers.

About the Riemann hypothesis:
I don't expect to prove it or disprove it. I'm a computer scientist, not a mathematician, so I want to be very careful about my claims... otherwise mathematicians will come and hunt (haunt?) me down.
I might be wrong but I understood that the Riemann hypothesis implies a tighter bound on the error term of the prime-counting function than the Prime Number Theorem. It is possible that some mathematician could use Riecoin blockchain data in order to draw some conclusions about the Riemann hypothesis. But I don't expect that to really happen, and it's believed to be true anyway...

Maybe I should have named it "Hardy-Littlewood k-tuple conjecture-coin" since we are directly testing it... but it's not catchy... maybe LittleHardWoodCoin... oh, well, too late now...

sorry. GPU or CPU?

CPU only at launch. Maybe, eventually, GPU.
