[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[markm]

Accepted as valid a block someone else somewhere else mined.

(Checked it and it turned out to be acceptable so was tentatively added to the chain, at least until orphaned, if indeed it should turn out some time that it does end up orphaned.)

My VPM miners are going down .  You are welcome as well. 

No blocks = No fun

Anybody know what god to pray to in order to mine a block? I'm thinking I've got the wrong one

Time to start doing pooled mining. yPool had a bit of a drought when I first started yesterday, but is now finding lots of blocks.

Hey Salfter. Could you post a screenshot from the v.0.2.1 miner?

It's a console program, so there's not much point in that.  Here's some of the most recent output from it running on my VPS:

Here is the source: https://github.com/jh000/jhPrimeminer

Is this trustworthy?

In what sense: that it produces valid output, or that it doesn't do something weird with your computer?  As for the first, it's mined about 1.25 XPM so far. That's more than I had previously gotten in a few days of solo mining (except for one block of 15.something XPM early on).  As for the second, you can do what I do: run it under Linux with Wine.  You could also browse through the source to see if there's anything fishy in it.  If I had the time, I'd try porting it to Linux myself; it should run a little better natively.

No blocks for me today ... which means 3 found within a few hours early tomorrow.

What does this mean in the debug.log?

Accepted what?

It means, that someone in the network solved a block and your client verified and accepted the solution, your local block chain was extended with received block and you can start to work on new block; debug.log should be full of messages like this. You can find more details about received block:

Code:

i run it in linux using wine. run fine but if you are still going to compile it try compiling with x64 flag. it's much faster

[maco]

I feel skeptical about that ypool miner. I do not know why. Anyone else tried it or can look deep enough in its source code to figure out anything fishy?

https://github.com/jh000/jhPrimeminer/tree/master/src I am looking it over as we speak, and I don't see any signs, but who knows.

Could help if others got involved.

Now that CPU mining for the average miner is dwindling, hopefully the community can start focusing some energy on getting more services! Would love to see an XPM marketplace soon.

That show was difficult to listen to. Every other phrase is how they don't understand how primecoin works! Why create a show with that topic if you know NOTHING about it?

This!. Outside of market trade there really isn't anything todo with the coin, Is there even gambling yet?

What does this mean in the debug.log?

Accepted what?

I've got a bad feeling based off your posts lately that you are trying to figure out how to make a fork of Primecoin. If I am right and it's a lame copy paste job with a couple of variables changed please don't bother.

You don't need to worry about me forking Primecoin, as I cannot even mine a Primecoin block let alone fork the client.

I just want to know why I can have just under 4000 PPS but not get a single block in 24 hours? And I wanted to know what it means when it says process block: Accepted?

Because difficulty is that high, I have 6000PPS and yesterday generated 3 blocks, today nothing, don't think it will get better.
People who rent VPS's, botnets and probably some gpu miners. That's the way to go if you want some decent profit, else you should see it as just for the fun of it.

Screenshot? What about the src

Anyone tried ypool?  It seems to function.  Just wondering if anyone has withdrew from it yet?

[forsetifox]

Been running tests for 2 days on the test-net and it looks like primecoind is crippled in some way.

Ran primecoind 1 hour and I end up with 10 blocks (had the same result 3 times) with sieve @ 1 million. If I run primecoin-qt for an hour I usually get about 30-60 blocks @ 1 million sieve. Did this test about 3-4 times.

This is with the hp4 client and only using one core on windows 7.
