Yes, to the people asking for a Dev. channel on IRC chat... Good for you. Why don't you all get into a nice greedy sweaty huddle and trap all the coins in there while people on the outside of this release get completely screwed over. It's neither good for the XPM currency nor good for your reputations to be screaming private collusion when it comes to optimizing a new POF miner.


However--if you're trust worthy enough to work on the miner and not exploit the currency (CKolivas) then by all means.

There are a lot of angry miners out there. I myself and probably the most unlucky with this currency, but the last 48 hours has not been all bad luck. A lot of it has been block stealing by individuals unwilling to share their complete information in this thread (NOT PEOPLE WHO HAVE SHARED, YOU ARE INNOCENT).


If somebody being ethical gets mad at me for being angry at unethical behavior then please read again. I'm upset with the hoarders and the selfish ones, not the kind and honest people sharing their techniques openly.

If people spent half the time trying to improve stuff as they do begging others to just give them the fruits of their work, they would be a lot wealthier - and wiser.

anyone have any idea how to get an estimated blocks/day for a given primepersec?  also, any information on how this changes with total network "primepersec"?  Like how is difficulty worked into this system?

'Primespersec' is apparently not much of a metric at all.  It varies wildly on the same machine, and does not seem to be in any way predictive of mining success.

The difficulty, if I understand it correctly, is the minimum length of the Cunningham chain you have to find to mine a block.

Compiling primecoind on windows seems to be working fine using the EasyWinBuilder link I provided on the last page. Now to see about doing some optimizations...

Calm down. There has been no stealing to my knowledge. Plenty of health competition, but no stealing.
Why would people just give you free coins? What's wrong with buying them?

It seems my blocks come in waves (3 in 1 hour) and then silence for 5-6 hours and again a wave of 3. And this keeps repeating for the last 24 hours.
Could this be an issue with the connection to the Primecoin network? Anyone having the same mining experience?

What a spread.  Grin

Spread-a-like-a-butter.

Nice to see that nobody wants to sell their coins for any baby values. Wink

I just bought 150XPM for 0.10 LTC so price is going DOWN!!! sell Smiley

pics or it didnt happen

See last trades... proof enough Smiley

Also got bid on XPM/BTC section. Check it out Smiley

Lol. Whoever sold for that price was a total idiot. I just sold 100 XPM for 15.5 LTC. XPM up and going STRONG. Wink 100 more mined XPM ready to sell when I decide to sell it.

For me it was something like this too. 3 in about 2 hours, then 6-7 hours nothing, then 3 in about 2 hours again... now nothing for 13 hours... lets see Wink

I don't think it is coincidence.

Most of us who started from the get go or have been on this coin awhile have noticed we are dropping off big time with the block finds.  I am just waiting for some kind soul to speak up on how they are mining away at them with another miner build.

I think a lot of people are frustrated because they don't understand the difference between pooled and solo mining.

In pooled mining, (ie, what we all do with Bitcoin), the work is broken down into a ton of discrete chunks - each miner is compensated when a block is solved based on their proportion of work contributed - ie everyone gets a slow, steady and somewhat predictable payout.

Solo minings different - blocks don't get shared, so each individual gets a much greater payout, but whether they get it or not is a LOT more dependent on whether they're lucky enough to solve a block before someone else does. There have only been 8000 or so blocks solved so far. I've got the miner running on various computers at varying pps rates - during the first 17 hours or so, I solved no blocks at all. Then they started getting solved. And the thing was, the difference between the number of blocks solved from a computer running at 10 pps and another running at 150pps is much smaller than the difference in prime generation rate.

So, there are 8000 blocks awarded so far.

Lets say there are 500 people attempting to mine them and each person is using 3 computers to do so - on average, if they've all been mining since the beginning, each computer would have solved 5.333 blocks. But the distribution is a lot more random; some people will have gotten 5 blocks, others have gotten zero, and others have gotten 20+. But that's the thing with solo mining. And if, in the beginning, there were only 50 people mining during the first hour, 200 mining 6 hours later, and 500 24-hours later, of course there will be drop-offs in the rate that people see blocks get solved...

Given the newness of the coin, the lack of markets for it, etc, I'd be shocked if someone had already figured out how to have a GPU solve the problems - it's not just rewriting the existing SHA algorithm that bitcoin uses, changing a couple lines to make it primecoin ready, it's revising everything about the miner to handle a completely different type of work. Optmizing the CPU miner? Sure. But even so, I don't think they'ed be churning out coins in this environment, as, again, I think the payout has a lot more to do with luck at this point than anything else including raw horse power.

Putting together some charts to demonstrate the distribution of the rewards I've seen so far.... maybe someone will find it to be of interest, who knows?

But in the meantime, if people want to see more predictable coin generation, then maybe they should start a fund to pay a bounty to the first person to develop a mining pool? i assume it'll be a lot of work, because, again, the dynamics of this coin are much different than any of the others, including this time to "mature". Or, you could make an informal "pool" with someone you know and really trust - just have both of you mine to the same wallet.dat file, and, as you add machines, the randomness that a single miner sees will be evened out more and more...

That my two cents. Utterly useless, because I'm not a programmer. But so far, I'm pretty excited about this coin and I can't quite fathom why people are getting upset with it already?

Im not frustrated; I'm glad as hell. I'm riding on 22 LTC of 140 sold XPM I mined in the past few days, with 50 XPM coming up. Cheesy

this guy gets it. GPU mining this coin is radically different. There's a reason XPM is getting traction and isn't just another altcoin.
