Disabling upnp adds to it too and im petty sure he hows about linux and AVX from start...

but tecnically is not pre-mine, i think it shoul be given another name.

No, there's no point in using more threads than you have cores (or double the amount of cores if you have HyperThreading from an i7). If you have equal or less threads than cores, each thread has a single core to run on, which is efficient. If you have more threads than cores, the OS has to let the threads take turns to compute things, which entails some overhead.

Bullshit.

Check the target time per block.

If the starting difficulty has been designed to ensure the first few miners rake in blocks way faster than the target tme, then you are not witness to the fact no pre-mine happened, you are in fact participating in pre-mining.

The whole scam is to deliberately use insanely low difficulty so that in very short time a huge pre-mine will be accomplished by those few people who get in on the pre-mine.

Once the difficulty reaches target, then maybe normal mining rather than pre-mining commences.

The start difficulty should be high enough that blocks will take far LONGER than target time UNLESS many miners get in on it.

Instead though the scammers deliberately set it way too low, so that an entire massive pre-mine can take place EVEN IF plenty of miners get in on it.

By recruiting miners into the pre-mine scam, they hope to basically bribe them into colluding with them in pulling off a huge pre-mine right in front of everyone's eyes.

unfortunately no

Ah okay, thanks for that information
Really love that im able to use my idle cpus from all my rigs at something=)

Also went for hours without hitting anything. but now im on a good streak, new found block pops up before i can close the previouse one! SWEET!

Is there any way to get information from yacoin-qt about the total hashing power in the client (from all the external rigs combined).
gethashpersec shows only 0 since all my computers use minerd towards yacoin.qt

In minerd my debug output shows a ton of Hash > Target  (false positive)

I've never seen debug mode before, I assume these are attemps to solve the block that are incorrect?  Sorry for the question if it's stupid but I could not find documentation on it anywhere.

ali1234 fork optimized for scrypt-jane. And yes, I know the command syntax.

The main problem on Fedora is the need to use a custom version of the openssl libraries, since the system-wide ones do not include elliptic curves.

So basically I have a deps dir where all the coins repo dirs live, so each makefile.fedora can have added into it -I../../deps/include and -L../../deps/lib so they all use the custom openssl I placed in deps (dependencies) dir.

to check if it has been pre mined, you need to be one of the first people to join the mining. then while you mine, see how many blocks have been generated by the network so far. If it's unreasonably large, then it was pre mined. i started mining when there were about 40 blocks on the network already. so i can defanately say that it wasn't pre mined

Shiet - good call. I guess the AWS fun is over...

hehe well, i did.
Im not an expert in this digital currency but im learning every day=P
theres a couple of holes to be filled, for example understand how to figure out if something has been pre mined. until then i check what
people write in the forums=)

Illegal instruction (core dumped)

come on.... show fedora some love I'm using ubuntu primarily. but face troubleshooting for quite a number of fedora users too

that's because you're submitting "small" difficulties. When solo mining, you submit the full difficulty. There's a big difference there

Who runs fedora?  But yeah, I use Ubuntu, those instructions are for Ubuntu too.

Probably a mix of both.  I was stuck in "newbie jail" so I couldn't weigh in earlier (this was the first thread I thought worth actually registering to post in).  I got a late start, about 8 hours after the coin was released.  I commenced mining with 800 servers with 2x Xeon E5450's (rows and rows of IBM BladeCenters) when difficulty was reaching 0.008.  Shortly after, I provisioned an additional 760 Amazon c1.xlarge instances, starting when difficulty was reaching 0.020.  I shut everything down when difficulty reached 0.1 last night.

Observations, orphan rate was about 20% across all 1560 servers, with an average of ~60 connections (modified outbound connection count in the client).  At the time I shut everything down with difficulty at 0.1, I was solving roughly 15% of the blocks.  Hash rate on the 2x E5450 servers averaged about 300kH/sec, and the Amazon c1.xlarge instances averaged about 200kH/sec, so I was mining with apprx 392,000kH/sec.  Based on that, I estimate the network hash rate was actually about 2,613,333kH/sec at that time.  Yeah, I know I could probably calculate a better figure from the block spacing vs. difficulty, but I didn't feel like digging into the source to determine the exact relationship between hash rate, difficulty and block solving rate.  And I know from trying to estimate block solving rate with litecoinpool's calculator that Yacoin's difficulty calculation differs significantly from LTC.  It's entirely possible that a large number of people also had the same bright idea to spin up a huge number of Amazon EC2 instances and that could possibly account for the hash rate, but I suspect the reality is that GPU farms were crunching Yacoin based on my observations.  Either that, or Amazon was the party that profited the most from Yacoin (so far).  :-)

Just for kicks, I fired 100 servers back up a bit ago to mine for a while starting when difficulty was 0.3, just to see how things compare.  I see 0% orphan rate now over the last couple hours and I'm definitely still solving blocks..

you might want to change "People trying linux for the first time," to "People trying Ubuntu linux for the first time," some might install something like fedora linux

UPnP isn´t in the client as someone said before, "too hard to compile" or similar.

And when i mine in a pool i get only ~1-5% invalids shares, not 100%

People trying linux for the first time, you need to run this command before you can make it with QTcreator

I really like that people here were all raving about the lack of a premine.  Apparently you've all been had if you've been running the Windows binaries of the program that were released at launch, because my Linux binaries are about 10x faster.  OP on linux probably had 10,000 blocks before anyone else.

Good call though for OP, release a Windows version that 95% of people on here will use that mines 10 times as slow, and it doesn't look like you've got an actual premine but you yourself are mining an order of magnitude faster than everyone else.  He'll probably be walking away with bags full of money.
