Mining on laptops is fun.

Well whatdayaknow, I got my first mined block just now, hah.

Nice, grats. Anyone have an equation for the block reward? I've skimmed through, didn't find anything though.
Seems it's going down gradually, but I'm not sure of the full trajectory.
I got 20.33 for my block, but it was fairly early on.

[coinerd]

CPUID checks. Hostname checks. Server specific information checks. It's not hard.

With the code on github it would have to be obfuscated somehow. Care to point out what you think it is? I would be astonished if he intentionally broke virtual CPUs. That is just rewarding botnets and punishing everyone else.

heh, heh heh.

Sunny, theoretically, won't the primes get bigger as we find more of them, so that it's impossible to maintain a uniform time in between blocks?  So that in fact, if the network hash rate remains constant over some period of time, difficulty will adjust lower?

Difficulty is measured by chain length, not by prime sizes. Block spacing is maintained via continuous difficulty adjustment.

Sunny, I keep observing periods where the block spacing is ~30seconds instead of ~60seconds, yet the difficulty isn't increasing by a corresponding factor.

Example period where block spacing is ~30seconds:

Code:

block 665 creation time = July 8, 2013, 04:11:39 difficulty = 7.03636408
block 675 creation time = July 8, 2013, 04:17:56 difficulty = 7.03710973

It has been a long time since blocks were spaced according to your specification so it would appear the variable difficulty should be set higher.

Hey guys, I got notification from the icon saying I got one block. But I couldn't find it in "transaction" or the "unconfirmed" amount.

What is the problem? Orphan?

Yeah, if nothing's in your transaction list, it's an orphan. Bad luck.

You could type "listtransactions" in the debug console just to be sure.

[Vorksholk]

Man, if PrimeCoin managed to punish for using cloud instances and server-class CPUs, that's an incredible feat, must have obfuscated it quite well! Curious to see how this develops.

Thanks mate. Orphan confirmed. I was so excited just now.....

I noticed it's going pretty quickly as well. Maybe some big power starting to jump on.

+1

[ReCat]

It's surely not server class CPU's. I'm mining away on my personally owned rack server.  I think they're just detecting big cloud instances. Anyways, It's a great idea. No scumbag instamine!

Difficulty adjustment is designed to be reasonably slow for security reasons. So in the first few days there may be some rush and higher orphan rate. Give it a few days the interests should level out.

[96redformula]

Strange enough my i5 can't find anything, but my ivy bridge celeron is finding them, two so far.

[romerun]

running on 3 hosts in a cloud, 1 core each, since launch found nothing..

[coinerd]

... I'm mining away on my personally owned rack server.  ... No scumbag instamine!

ohhh the irony!

[drummerjdb666]

I've found two blocks in the past ten hours

I'm curious to see other people's speeds.. this is the fastest I have seen my I7  I'm only @ 4.372

[n4ru]

Hm. I appear to be generating; I use setgenerate true.

But nothing appears to be mined after about an hour.

Difficulty already high?

[loloman]

I have 4 PCs, ~150 primes/s each, only 20 XPM after 10 hours.
WTF  

[Tuck Fheman]

I've been following Primecoins progress and I'm excited to see where it ends up. It appears to be the answer to the (other cryptocurrencies) pundits issues.

Mining with i7 3.22 @ 104 primespersec (incrementally increasing slowly).
