[ANN] official NovaCoin thread - the original PoS+scrypt coin.

So those shares reported by the miner are not directly the shares you are paid for, atleast they don't seem to add to the "Current payout" in regular basis?

Correct.

I see the P2Pool program is reporting "Expected time to share", is this what increases the "Current payout" once I get the share from P2Pool?

Yes, that's it.

How do I figure out how long the average block generation time should be?  I have 12 Mh/s and was trying to decide about solomining or not.

Anyone mining NVC at nvc.khore.org? If so, what is your invalid percentage? I just started tonight. Seems stable enough, but my invalid percentage is ~8%. When mining LTC at ozcoin using the same setup, cgminer flags, etc I had less than 1% invalids. Thoughts?

Also, is there a dedicated thread for nvc.khore.org? I searched and did not find anything.

I'm pretty sure that you would be better off mining at p2pool. I've noticed that even miners with huge hashrates tend to use pools. They wouldn't do that if solomining were more profitable.

You should remove blkindex.dat and blk0001.dat before starting new client, otherwise you will get assert exception.

P.S. attached readme file to binaries download page.

When compiling under OSX Mountain Lion 10.8.2 I get this error:

What am I doing wrong?

[Balthazar]

It seems that llvm-g++ can't understand AT&T assembler properly. You can try gcc, this may be helpful in your case.

P.S. I will add C implementation of scrypt soon.

did you pay invalid shares ?

[Balthazar]

DOA shares are not paid. Orphaned shares are partially paid in the p2pool, in case when orphaned share generates a block. So, you need to enable --submit-stale feature in your miner to prevent lost of the valid blocks.

Hmmm...

I try to use but qt-client crash many times...

So P2Pool lost conection, than mining are useless...

There is a fix? I using Windows 7 and Windows 2003 Server.

We trying to debug it now.

I've received message from kha0s, he successfully created the crashdump and we will analyze it 2-3 hours later. More info will be available later.

Invalid percentage seems lower in the Donor pools, but that may just be me.

Is stratum fixed in the current P2pool build?

[Balthazar]

Stratum is unavailable for NVC and PPC yet. It's because we use different transaction format and current mining software can't handle this correctly.

We have a plan to release modified stratum server for NVC and PPC, and stratum-mining-proxy with new transactions format support.

[codegnome]

Has anyone had 'current payment' go to 0 with P2pool? It has happened to me numerous times and I have to restart the client to get payout working again.
 

[Balthazar]

codegnome, it's just estimation. Real payments can differ from this value, and users are often receive payments while p2pool displays zero.

[codegnome]

OK thanks Balthazar

I want to try mining at the p2pool, the novaco.in pool, but I can't figure out the miner config. What do I put into cgminer for the port?

[Bitinvestor]

I want to try mining at the p2pool, the novaco.in pool, but I can't figure out the miner config. What do I put into cgminer for the port?

Host 127.0.0.1 and port 8336 for p2pool.

Simple p2pool guide for windows users:

Hi,

Is there somewhere a detailed guide on how to use p2pool with nvc?

The readme file attached was not helpful to me at all using the precomplied .exe.

Thanks,
balu

It's quite simple.

1) You need to run novacoin client in server mode, just like in case of solo mining. Create file novacoin.conf in

C:\Users\Your user name\AppData\Roaming\NovaCoin

with contents like this:

rpcuser=user
rpcpassword=password
server=1

2) Start client and wait for syncronization proccess
3) Double-click on run_p2pool.exe, wait until shares chain download will be completed
3) Point your miners to http://any_user:any_password@127.0.0.1:8336/

You are right, it does not. However no other gcc I could get my hands on could do this under mac osx.

Fortunately there is a solution and I was abale to compile it just fine. Use https://github.com/iongchun/cpuminer/blob/cpumine/nomacro.pl to expand the macros.

Code:

sudo perl nomacro.pl scrypt-x86_64.S

Cheers.
