bitminter has nmc earning on stratum

i mined there for a few days to try, getting paid while waiting for blocks is nice, but the pay out is not nearly as good as on slush.

How do you know it is on stratum? (and not just on getwork)

They have a lot of users on both interfaces - so it quite possible that just those on getwork make the NMCs, but similarly as Slush's - everyone (on both stratum and getwork) receives NMCs.

could be, i was connected to stratum though.

i was making more nmc then btc lol.

Looks like I missed the excitement of 3, almost 4, blocks in a row.  But I did pop back with 1.2 GH/s just in time to catch this other nice one - squeezed by with 12 shares in 24 seconds....  Grin

Decided to give it a go with all miners using one worker...

Lucky you! Smiley
At 910MH I barely managed to get 3...

Still - for a 24sec round - any income is just bonus.

Approx. cluster performance (30 min average):   10019.818 Ghash/s

it just keeps going up, serious power being added to the pool.

That's interesting ... I'm connected via the stratum proxy (I'm using an older miner that can do getwork only). I've noticed on a few other occasions that it takes a bit extra time (like 10-15sec) for my workers to resync.

I wonder if my poor performance is due to me using the the proxy or it was just a slow network or some other fluke...

10% difference can well be because of luck spike and will stay for exactly 30min

Wait, what? I'm not sure I know what you mean there, but I must say I'm intrigued to find out.

please excuse my ignorance, i'm a newbie, but are you saying luck increases the hash power, i noticed it went up the other (exceptional) day, i put this down to more people joining the pool.

If that's what he's saying then he's so very wrong. We're not talking about the network here. We know how many shares are contributed, so we have a very good estimation of the hashrate.

If the variable difficulty shares were set to extremely high difficulty levels (close to the current network difficulty) then maybe this would be the case and it would be hard to judge the pool's hashrate. But they're not so it isn't.

It doesnt seem logical to me whatsoever that luck would increase hash rate, but i'm a newbie and here to learn what i can, all i can do is ask questions atm. all explanations welcome.

I already am mining on Slush's Pool 14 hours. Power 2200Mh\s. Why I do not calculate Namecoin?

Unconfirmed reward:0.00000000 NMC
Confirmed reward:  0.00000000 NMC

Connected to stratum. Cgminer 3.1.0

Hi (sorry another noob question)

I've only mined with Slush's pool for BTC and am now taking more of an active interest in the statistics page
(they also seem to be referred to on this thread a lot! lol)

So is the Round duration
Current round duration:   4:58:21
and the
Block duration 0:17:24

The same figure?

IE how long the pool is working to solve 1 block?

So the shorter time being better?

I see earlier in the thread reference's to 3 in an hour (Hatrick!) so are we paying for that with a 5 hour block?

or am i way of the mark here?

OK look here http://bitcoin.sipa.be/speed-lin-2k.png (about the luck spikes) and pay attention to the 8 hour average - it jumps for over 20% (60TH to 100TH), while 1 day average is more stable at ~75-80Th

Why is it so: you get a work to hash by trying 2^32 nonces with it and this will take for your hardware (let's say) 5sec, but it may return from 0 up to 2^32 valid shares. On average (hashing for a long time) you will get 1 share for each getwork (1 every 5sec), but accidentally you hit a getwork that returns 5 shares in the same 5sec - it looks like you have 5 times faster miner, because of the luck spike. After few seconds your average hashrate goes back to normal, as you don't get such works regularly.

It is the same for the pool - some miner submits more shares, than his speed, which 'tricks' the pool (for while), that it got higher hasrate

Hi, under system statistics on Slush pool you have Bitcoin blocks and Namecoin blocks..you can look there for NMC,

Hey everyone. Look out for round 17979. It maybe another round in which people get stilted on their earnings. I have a new theory about it. It started when I was watching my account page. I saw the estimated reward drop from a typical .003 or so to .00000001. Then over the course of 30 minutes it eked up to .00000007, then .00000015, .00000240, and get close to my usual. What was going on at the time, however, was the total score for the round had not reset in a good 15-20 blocks. I'm not sure yet how often the total score resets but it was a 14-digit number starting in 5 before the fever broke. Some people last time thought it was stratum backing up and not properly reporting shares but it's this danged "hop-proof" mechanic Slush employs! I've got a thing or two to say about that in general, but I think I may have found the bug.

No, it's not. We have a much better estimate for the number of hashes submitted to the pool than to the network. You've estimated the variance for the network in a previous post - try estimating it instead with Difficulty = 1 instead of Difficulty = 10 million.

I've got a thing or two to say about that in general, but I think I may have found the bug.

I noticed the same. I suspect there may have been another DDoS attack as all of my miners got disconnected:



and then 2hrs later:



After the reconnect I noticed that my proxy was connected to 54.225.68.97:3333.
I don't know if it was the same IP before that. I'm guessing that it is possible that some of that pool's IPs  got affected but not all.

all times are GMT-7 - so it started at 07:10:43 UTC and reconnected at 07:16:43 - it lasted almost exactly 6 minutes. Although looking at when results started being rejected - that's almost exactly a minute earlier.

On the good side - this is going to be a pretty large block, so that gave me enough time for my score to restore to normal (in about an hour).

That's the thing, Slush's hop-resistant algorithm only really works well on short rounds. On occasion when we've had <5 minute rounds I can make a killing but there is nearly no difference in reward between a 2-hour round and a (soon-to-be) 6-hour round. Is that a small/medium miner thing, or can bigger miners corroborate? I get about 1.8 Gh/s between me and my buddy. On a PPS pool you get what you work for but here, because the score metric resets every so often, everyone is pretty much capped for any given round. At this 10.1M difficulty the highest reward on a single round I've gotten was .00576. Everything the same, a 6-hour round should absolutely pay better than a 1-hour. More work, more uptime, higher cost of running.
