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

[hak8or]

This does not make any sense, the diff has not even risen enough yet.

I mined two blocks roughly 3 hours apart and for the next 24 hours ago I get no mined blocks. I am using an I5-3570k at stock with "primespersec" : 129, yet nothing for 24 hours. Surely I am not this unlucky, am I? The processor utilization is actually at about 100% too, so I am surely mining. Anyone know what is going on?

[rethaw]

First transaction has been made

I believe that is this block
With a transaction for 19.13 XPM

But was it for pizza?

I got my first block after 23 hours of mining at 120 PPS...

[romerun]

alright we need a new website for primecoin.org, let's not get into the same mistake again.

I just got my third block now, it seems every time after I post here I get a block, hah.

It's so nice to be able to CPU mine a coin again.

Makes me nostalgic!

And a good work out for my i3 which has been pretty idle recently.

[ReCat]

can anyone help me and tell me why this is so low please ?
"blocks" : 3244,

use setgenerate true 2

or 4 for 4 cores.. use the number of physical cores you have.. without the "-"

do i need to do this i have 32 cores but my pps is 1 something is not right

big rigs are nerfed. go mine on a regular computer like everyone else.

Block spacing appears to be steady in a range of 30-40 seconds, the increases in difficulty are keeping it in this range for now. However, if an optimized miner with a large improvement in prime generation speed was released (ahem luke-jr's BFGminer) then I would expect to see a block spacing of ~10 seconds and the difficulty would take days to catch up.

Too bad nobody is doing altcoin releases sensibly in this area.
There should be a minimum difficulty set high enough that it doesn't go through a rush like this.
Bitcoin didn't break difficulty 1 for months (if not longer).

True, on the other hand if Sunny had released the default client with a difficulty of 8 then blocks would have been spaced >60 seconds and difficulty would have adjusted slowly downwards. Based on his benchmarking before release he must have been happy that 7 was the right place to start.

There's also the fact that he'd need to take into consideration whether someone of questionable morals was going to release a miner that mines 10x or 100x what he expected. How can that be predicted, andeven if it could be predicted, how could the timing of it be predicted? It's just not practical. Out of the many releases, this was a good one.

Are we at the point yet where 100pps puts you at higher odds of being struck by lightning?

If I am not mistaken, the starting difficulty was 6.

PrimeCoin block time differences, clipping the first two.




The fit line is y = -0.005740965 * x + 45.7769270

The mean is much lower than the fit line, at 36.02s.

Typing 'primespersec' in the console returns 'Method not found (code -32601)'. Anyone else getting this?

However, 'getmininginfo' shows:

{
"blocks" : 3449,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"errors" : "",
"generate" : true,
"genproclimit" : 2,
"primespersec" : 76,
"pooledtx" : 0,
"testnet" : false
}

The CPU certainly sounds like it's mining! Though no blocks found over night

Unless I'm misreading the source code (which is certainly a possibility!), 6 is the minimum difficulty for primecoin and it started at 7:

lines 149-150 in prime.cpp

Code:

unsigned int nTargetInitialLength = 7; // initial chain length target
unsigned int nTargetMinLength = 6;     // minimum chain length target

additionally, looks like the initial and min difficulties on test net were 5 and 2, respectively. (lines 2730-2731 in main.cpp)

makes sense, my miner was not synced and wasn't mining at the time the command was sent.

Gentoo ebuild of the daemon here, for the true believers. Modified from bitcoind 0.8.2 ebuild.

+1 for you! It works and I'm actually showing non-zero pps on my 16-core opteron system now. It's only 1-2 primespersec but it's an improvement!

Code:

# primecoind getinfo
{
    "version" : "v0.1.0.0-g25659c1-beta",
    "protocolversion" : 70001,
    "walletversion" : 60000,

    "blocks" : 3458,
    "moneysupply" : 68334.18000000,
    "timeoffset" : 0,
    "connections" : 8,
    "proxy" : "",
    "testnet" : false,
    "keypoololdest" : 1373223782,
    "keypoolsize" : 101,
    "paytxfee" : 0.00000000,
    "errors" : ""
}

Code:

# primecoind getmininginfo
{
    "blocks" : 3459,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "errors" : "",

}

Is there a way to check past difficulty levels? Or did anyone take note of what it has been? I'm going to attempt to keep a log over the next few days to see if we can get an idea of where the difficulty is going (and therefore what the reward/inflation rate will be). Also this should be useful in determining the compute power of the network.

Currently it sits at d=7.23843342. This jives well with the block reward I just received (r=19.07).

(999 / d^2) = r <=> d = sqrt(999/r)

So, with a reward of 19.07 we have d=7.23781.

In the time it took me to write this, the difficulty changed to d=7.24123460 in about 15 minutes. So, if my math was right the difficulty increased by almost 0.04% in 15 min or almost 0.003% per block. Using both of the blocks I found gives around 0.002% difficulty increase per block. This is all assuming a one minute block time, so take this all with a grain of salt.

According to Bitcoin Magazine, a doubling of computer power would cause a 0.02% increase in the difficulty of the next block. I'm off to bed!

I started mining 1h late. Sorry for the colors, I am using my vision enhancement nano-augmentations:

That would make the difficulty increase for all time ~0.00574% per block.
