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

Looks like it either has problem with cgminer, or it has problem with getwork for solo mining. Blocks are being rejected due to wrong hash submitted via getwork. Balthazar, are you sure that getwork is properly supported? Have you tested with cgminer?

I think that it's result of 120s expire time, which is default value for cgminer and hard-coded value for reaper. I seen people which mined it at 4-8 mh/s... Of course, they got stales, but stales rate not so dramatic. There is no magic.

P.S. Tested it with reaper at diff 0.0004, got almost 100% of stales... Then I switched to cgminer with -E 1 and got "only" 55% stales at this difficulty.
P.P.S. Target is 6 blocks per hour (like PPC and Bitcoin), so situation will normalize in near future.

I have successfully mined a block using getwork.

I am now testing artforz's fork of pushpool

https://github.com/ArtForz/pushpool

For blkmon, I use:

Code:

#!/usr/bin/env python
from jsonrpc.authproxy import AuthServiceProxy
import sys
import os

access = AuthServiceProxy("http://RPCUSER:RPCPASS@127.0.0.1:8332")
blockcount = access.getblockcount()
from time import sleep
while(True):
        newcount = access.getblockcount()
        if newcount > blockcount:
                os.system("killall -s SIGUSR1 pushpoold")
                sys.stdout.write("B")
                sys.stdout.flush()
                blockcount = newcount
                sleep(1)
        else:
                sleep(0.1)

There is a -blocknotify=/path/to/your/script.sh option, you can use it instead of blkmond. script.sh will be executed for each new block event.

ok, ill try once again.

solo mining 4500kh/s  with cgminer -E 1

/edit:

blocks being found,

 solution is public,   4848 blocks and 249097.89 coins,  February 12, 2013, 02:09:34 AM

/edit2:

pool works again, noticed some bugs fixed also.

Having serious problems connecting to nova pool.  Did as site instructed but get no connection.  And I guess i am not clever enough to figure out how to solo for NVC

[Balthazar]

Code:

2013-02-13 01:46:08.388212 Pool: 80659H/s Stale rate: 0.0% Expected time to block: 2.3 days

Currently working on patches for p2pool...

Good idea. Are you adding it to both the SHA256 and scrypt sides?

How about also adding merged mining? On the scrypt side that would be a first, and people would have something to merged-mine alongside litecoin. Though personally I am more interested in the merging with the SHA256 side.

Hm... By the "SHA256 side" you mean PPCoin?

[Zedster]

Actually I got up solo mining. More to see if I could.

Oh never mind I was thinking of RUCoin - both types of hashing. All you Russian coins look alike hahahahah. But adding it to PPCoin as well would be nice, sure.

I remember only one such ridiculous fork, it's rucoin. Not sure what are you talking about.

Try again better, and then I'll pay you 0.1 btc. Your trolling skill not so good, as we can see.

Novacoin suffers the same issue as PPCoin did with the base58.h file.

My commit merged into the PPCoin official development Tree allows Vanitygen private addresses to be imported. This also corrects the Base58 private key version the daemon produces when dumping a private key.

https://github.com/Hartland/ppcoin

The patch file should work exactly the same in Novacoin, with no changes needed. I can fork and request a pull, or the Novacoin developers can just patch it themselves, either way is OK with me.


Vanitygen will need  -X 08 switch to produce Novacoin addresses. First digit of the pattern must be "4".

./vanitygen -i -X 08 4eee
Difficulty: 19627
Pattern: 4eee

Been solo mining for a few hours now.  All my found blocks are being rejected.  Used -E 1 fro cgminer but still no joy. Any ideas?

post screen or log , maybe diff<target

only "BLOCK!! on pool 0 " are real finds

From what little I understand that you said. I am still confused.

winblows ppl dont get the difference between scrypt and sha256d lol

Yes my ignorance abounds. Thank you for the helpful insight.

And thanks to your insight I figured it out.
