What is this picture?
Is it from a game?

http://en.wikipedia.org/wiki/Mersenne_twister#Disadvantages
The algorithm in its native form is not suitable for cryptography (unlike Blum Blum Shub). Observing a sufficient number of iterations (624 in the case of MT19937, since this is the size of the state vector from which future iterations are produced) allows one to predict all future iterations.

Do you need 100000 blocks or do you need 624 iterations to predict all future iterations?

80000 blocks are generated, but I don't know how to predict, and I don't know whether it matters, when the next big reward is.

Doesn't the Mersenne Twister function use some randomizer besides the seed? Maybe a time component? Otherwise it would just be a function. Or did I miss something big?

Has anyone made a list of all the past and future reward blocks of Sexcoin?  

This seems like an easy list to make, because the Mersenne Twister is seeded with the block height.  Thus we know the seed for every block, past and future.

main.cpp
Code:
		//superblock random reward
int rand = generateMTRandom(nHeight, 100000);

I noticed the network settled down to a nice hashrate for our smaller miners, but I suspect that the huge surge in hashrate we've experienced was caused by big miners grabbing some SXC to stash away, and it left the network lagging a little..

We decided to point some extra hashpower at the pool so the small miners aren't left slogging through "hard" blocks and get a cut of every block. The difficulty should change at block 83040, and we'll start pulling hashpower off the pool as difficulty decreases so smaller miners make more..

There will be random "Testing Bonuses" to miners on the pool of 69 SXC. To qualify a miner simply has to have a hashrate on the pool at the time of the bonus.

Good morning  Grin

The p2pool is working well so far, as lavajumper has mentioned we are leaving it up for a few days to make sure the server is still stable before we officially announce it as a pool.. The payouts are perfect, and the PPLNS window is as small as we could make it and has a nice response to changes in hashpower..

The hashrate has gone down, but the difficulty is reasonably high, so once it adjusts mining should be pretty good.. If the hashrate doesn't climb again.. Personally I'm hoping it will drop to those super easy to mine levels, but of course it might not make it..

I tried to compile it on Fedora, it was pain, I wasn't successful.
https://bitcointalk.org/index.php?topic=85228.0;all
https://bitcointalksearch.org/topic/building-current-bitcoind-on-fedora-19-253688
didn't help me.
Anything I'm doing wrong.

By the way: On SUSE and ubuntu, the client is doing great.


The only way I know to compile on Fedora and CentOs is to frankenstein your system. Pull the SSL source, build the libs and point the sexcoin build to the new SSL includes/libs. I have seen references to perhaps an epel package that has the ECC built, but have not been able to locate them. As much as I'd love to get a tutorial out, I have not had the time to work on these platforms. read: I have not been successful on them either. This is something I'm pretty sure I'll do once we have 'other' stuff for the coin taken care of. Hopefully, I can fold SSL source build into a Fedora/CentOs build package that will not interfere with a running system. But as its looking right now, that really is a long way off.

LOL...any takers!?  Grin

And yeah... wtf?

EDIT: First time I saw that post with the RPM link. No luck with that?? What was breaking the build?

Up on https://github.com/sexcoin-project/

The compiled clients are for unbuntu 13.0.4, 32 and 64 bit..  (edit : and windows of course)
There are dependencies as well, in the clients repo..
check the first post of this thread for help, and the location of openSUSE rpm's if you are are old school, and using feadora..

Although this isn't my department, Max and Lava are the client experts so I gotta say...

If you are compiling in Windows, I can't help you...
Pull the master branch and build. If you browse to src/version.h you'll see the version bump.
All the notices about 0.6.3.0 are from the initial upload, and hadn't changed.

Really, there weren't a whole lot of major changes, mostly a HUGE cleanup and a checkpoint added, followed by a whole lot of testing. And those changes were done before the version bump and initial upload.

If you're compiling on Linux, here's some notes I collected while testing http://www.altcointalk.co.uk/index.php/topic,75.0.html

If you get stuck, lemme know.

I'm going to take a look at building the code tomorrow and see if I can create an RPM spec file that work with Fedora. Unless someone else is already doing that.

The problem with coins and fedora is that fedora ships openssl compiled without ECC.

I have OpenSUSE RPMs for various coins at https://build.opensuse.org/project/show?project=home%3Ap_conrad:coins (sexcoin still based on original source, but I'm working on moving to the new client repo).

Update: new client builds available

could you release new sources for sexcoin daemon ?
https://github.com/sexcoin-project/sexcoin
because there is no new version in sources

Hot Spit! THAT's what a p2pool should look like!  Cool


LittleDigger gets the real credit! He figured out ALL the settings and walked me through getting it running on Windows.
Mega-Props!

I'm just glad we've got something up and working. IT IS STILL BETA!!! We are going to watch it over the next few days.
We're going to start fine-tuning now.

I've got enough confidence in it to do this:

we need pools that work good, not just pools that look good..

That's the spirit! :-)

Great job, thanks a lot!

Sigh.... Nope .. The network hashrate is still going up..

But we still have our intrepid miners in the new pool..
