Using Coinotron under CGminer.

GPU: 6850 @ 12.10Kh/s (is it normal?)

Q:26, A:2... Tried "-E 1", "-E 120", "(nothing)"... still same result.

No, it's too slow. You can get ~250-270 khash/s.

P.S. -E irrelevant for pooled mining.

Coinotron is under DDOS attack.

Are you increasing the intensity? (g>i>select device>enter intensity value) when cgminer launches it's going to be low by default unless you set the parameter in your config.

Ideal sha256 values to do not apply to scrypt.

I tried solo mining NVC today since coinotron is down due to the DDOS.  I've gotten about 24 blocks today.  Only 4 were accepted.  The other 20 or so were rejected.  Any thoughts on why the rejection rate might be so high?

Using cgminer -E 1


Charlie Kelly: I'm pleading the 5th.  The Attorney: I would advise you do that.  Charlie Kelly: I'll take that advice under cooperation, alright? Now, let's say you and I go toe-to-toe on bird law and see who comes out the victor?  The Attorney: You know, I don't think I'm going to do anything close to that and I can clearly see you know nothing about the law.

Maybe when you are solo mining your mining software doesn't stop working on a block if a new one is found? I think this feature is called "long poll." I'm not an expert Bitcoin miner, so I hope someone will verify this for me.

I think stratum is a bidirectional protocol so it's built to do this even better. Long polling is a bit of a hack of the Bitcoin client RPC interface. Stratum is a fresh start and designing the protocol to be more appropriate for what Bitcoin has become. RPC was fine when Bitcoin started but its no longer appropriate.

I'm also getting alot of Pool 0 not providing work fast enough messages.

I'd suggest moving to Bitcoin mining temporarily because you aren't going to be able to mine NVC efficiently enough for it to be worth it. You can still mine TRC, PPC and FRC with p2pool IIRC all of these have p2pool set up and are not dependant on coinotron.

24 over the target ? wait waaat? do you have any idea what hashpower is needed to mine 24blocks a day with current difficulty over 11 ? I think you ment rejects below target.

All I know is cgminer is telling me I'm getting rejected blocks. 

For example: 
GPU 0: - A:1 R:3     
GPU 1: - A:0 R:2
GPU 2: - A:0 R:1

hiting 4 blocks means you have like 19 mhash ultrarig  ~1900kh /s rig or incredibly lucky. those are under target rejects, you are ok.

Ah well good to know then.  I thought there was a problem and brought all of my rigs down.  I'll get 'em running again.  And each block contains roughly 16.75 NVC?

By the way, how can you see  what the current difficulty is? I don't see a debug menu to type: getmininginfo

Edit: Also, what is an under target reject? Never seen that before when solo mining other coins.

you can see in in the miner window , cgminer shows about 65k*diff which is about 720k right now, dont know why and I heard BFGminer shows it correctly. also i missed one zero Sad , so its more like  2000kh/s .

 recejts like this are ok :
rejected 39f92hac93 diff 620k/720k  gpu 0 pool 0  [difficulty below target]

this is a real find:
BLOCK! 39f92hac93 diff 1.23M/720k gpu 0 pool 0

and this a a bad reject i can't explain
rejected  39f92hac93 diff 1.23M/720k gpu 0 pool 0

ant thit is a stale:
rejected  39f92hac93 diff 1.23M/720k gpu 0 pool 0 [unknown work  - stale]

all of the top of my head so migh be a little wrong but you should get the point.

Working on p2pool compatibility, so some fixes released in 0.2.4 build.

1) https://github.com/CryptoManiac/novacoin/commit/440991a0f8dbdd6147e56ec55e3423429cee6e90

Adds new RPC call, which allows you to generate new public keys.

2) https://github.com/CryptoManiac/novacoin/commit/3b2f04b998fca87c3f5e57b6fbb78f01da699a34

Adds incompatible changes in blocks signing, in order to make this transparent and decentralized. You need upgrade your client to new version before February 24.

The disclosure of problem:

Quote
Each miner in p2pool has his own output in coinbase. If there are N users, there will be N+2 outputs. Each of N outputs pays to miners according to their PPLNS work, and vout[N+1] pays donation % for developers of p2pool. The last output pays nothing and contains service information.

Even if we modify p2pool to force it make vout[0] owned by winning share submitter, it's not a solution, it's only workaround. This will remove possibility of block construction by other users (not a miners of winning share).

I.e. only block founder will be able to submit winning share into cryptocurrency network. Because only miner of winning share has corresponding private key for vout[0].

If submission of block by winning share miner fails, nobody will be able to replace him, and block will be lost. Even if other p2pool nodes received all block data through p2pool network.

This problem can be solved with my patch, this allow users to sign block by using any private key, if this key corresponds with one of vout[N].

Several other things to take note:

1) Each coinbase output must have value >= 0.01 coin, p2pool needs to be aware of it otherwise block could get rejected.
2) If coinbase size is greater than 1KB then it needs to pay 0.01 fee per additional KB, otherwise block could get rejected.
3) Make sure all the transaction timestamps not to exceed block timestamp (throw out those tx with larger timestamps) or block could get rejected.

Already thought about it, PPC/NVC p2pool will destruct 0.01 coin per each block by sending it to non-redeemable script. To satisfy the protocol.
