[4+ EH] Slush Pool (slushpool.com); Overt AsicBoost; World First Mining Pool

[johnyj]

This is fun and very interesting. Slush's score method gave me months of interesting research last year. Try digging into the complexity - you might enjoy it

I think you're over-thinking all this. Do you want to stay at slush's pool? Are you ok with losing a tiny percentage of your earnings to pool hoppers in exchange for a stable pool and a responsible pool op with a good reputation who has the longest running top 5 pool? You don't need to be concerned with the technical aspects of pool hopping if you don't want to.

The reason I don't want to dig into this is because I'm not a pool hopper and I just get some network disturbance from time to time, and if his intelligent scheme can not recognize this, that is a bad implementation, no need to dig more

I've been using this pool from the start(2011), but just recently I discovered this problem, how do you differentiate this from pool stealing?

I am now having problems on 2 miners (1 Cg-miner, 2 CPU miners) across 2 machines (I am running 17)

One machine is just a CPU Miner (G) is blocked
One Machine is a CPU GPU miner (L) both Coin-miner or Cg-miner are blocked

Then Suddenly (after 5 hours) G11

Judging because of extremely rare 2/10 second rounds? People are upset when the luck is bad,  but people are also upset when the luck is good... :-) I don't remember how such "good luck" happen last time, it is really rare.

no, no, I'm not upset as I completely understand the logic behind it and as I said in the long run I earn exactly what I would expect. Having said that, I do realise, that as difficulty increases even gh/s miner will mine less & then even less than less.

btw if the round lasted really short and there would be only one share submitted in the whole pool in that round and if that share was mine, then I would earn 49.xxx BTC for that round and would send a bottle of very good wine to slush.

my point is: 1gh/s rig will mine about 838 diff1 shares/h = 0.23... shares/s ~= 1 in 4 chance rig will submit a share in that 1 s. if round lasts 2 seconds then we would have approx. 50% chance that rig will submit a share in that time. since network latency is about 20-50 ms depending on your location (20ms in internet terms is very good indeed) and can jump to 80ms, then your chances of submitting a share are much lower because of round trip delay (which is 2x latency) and processing time ( cgminer, or, network card, router with nat, adsl etc, which I cannot measure but would estimate to be another 20ms ) then my 2 second round allows for 1.8s of hash finding or even less. this is where this is painful.

i understand your argument that I could be lucky and submit 3 shares in those 2 seconds by pure luck, but the latency bias still remains.

on the other hand Jeff running his asic miner on diff1 (he should not do it, but there is no way to stop him) with 68 gh/s, is submitting 15 shares / s so he has and extra edge in this situation. above the obvious gh/s advantage.

dialling back share difficulty to 1/2 or 1/4 is probably also not such a good idea. delaying payoff till more than one round is completed who's combined duration is bigger than some threshold is also probably not such a good idea....

Cheers!

LOL

Just realized that the 10s block was my best reward for the day. Almost 10x the average.

[jerethdaminer]

With the exchange rate and increasing difficulty, you could have a shot at getting Slush to lower the minimum threshold. How much do you have in there anyway and how long would it take you to mine to 0.05?

ive been mining at 120mhash/s for 3 days and am at unconfirmed .03 so not that long to get to .05 if you leave it crunching,

still a little shocked at some of these quick rounds im guessing asic is coming into play

Network disturbances don't make you a pool hopper. To pool-hop and benefit from it, you need to mine strategically and requires specialised mining proxies. Intermittent network problems won't make you earn more than you're due. The implementation is fine.

I've been using this pool from the start(2011), but just recently I discovered this problem, how do you differentiate this from pool stealing?

Pool hopping isn't stealing, it's just maximising the value of each share you submit. Under fair reward methods this is not possible. Under a pure proportional reward method, you can increase your earnings by a very large amount, and in the limit fulltimers at such a pool would lose about 43% of their expected share value. Here at Slush's pool, the losses to pool hoppers are mitigated somewhat and so fulltime miners only lose one or two percent to pool hoppers.

I'm still getting the "No connections could be made because the target machine actively refused it" error in guiminer

It's only when I use it through my vpn, which I consider essential for using the internet.  Why is my VPN fucking this up?

I downloaded the latest guiminer before I made this post and am still getting the error.

Slush? You around bro?  Any idea how I can fix this?

I'm pretty sure it starts hashing automatically after a few minutes of getting the error.  I'll report back.

Add this in the server.ini of guiminer.

restart guiminer, Try the alt server. All your setting should be there still.

Code:

        {
            "balance_host": "mining.bitcoin.cz", 
            "balance_token_url": "http://mining.bitcoin.cz/accounts/token-manage/", 
            "balance_url": "/accounts/profile/json/%s", 
            "host": "stratum.bitcoin.cz", 
            "name": "slush's pool(IPv6/alt)", 
            "port": 3333, 
            "url": "http://mining.bitcoin.cz"
        }, 

This seems to be my issue but I am NOT using GUI miner I am doing this command line:

"C:\Users\Liquid Silver\Dropbox\Hashing\guiminer\miners\Coin\coin-miner.exe" -u Galaxy -p 1234 -o stratum+tcp://stratum.bitcoin.cz:3333

Also tried: -o stratum+tcp://api-stratum.bitcoin.cz:3333

[dlauth]

I have .02 BTC and .001 NMC.

Setup my miner on LTC now and dont want to mess with it since it is working.

[fourd00rgtz]

Just realized that the 10s block was my best reward for the day. Almost 10x the average.

I snuck in 8 shares on the 2s block for 0.08btc, that's like $18/2s or $129600 per hour, lol.

still a little shocked at some of these quick rounds im guessing asic is coming into play

I am an ASIC and I've seen my rewards shrink by quite a bit. The current Pool GH/s is being shared among many more users than normal. At the current rate I am only seeing about .25 BTC per hour.

Edit: Currently using a difficulty setting of 512.

Well that's too bad   I was mining at .001 per block with 2 GPUs.  Stopped that.  Be happy that you are earning ~$55 an hour.

is it not more profitable to solo at this point with an asic?

Pool hashrate doesn't matter. Network difficulty does. Difficulty increased about a week ago by ~ 14% - was your percentage drop in earnings about the same?

It is hard to say without using a calculator.

I would say before today it was generally .47 to .41 per block. Each block took about 1.5 to 1 hour to solve on Slush Pool.

Some blocks take longer than others so it's pretty hard to say. The graphs say I was earning about 7BTC on March the 22nd (or thereabouts) and right now it is between 4.3~to~6 BTC per day.

It seems to largely depend on pool luck if I understood correctly. The Avalon ASIC is my first entry into BTC mining. I am a newbie. I just noticed the stats on one page say that the miner has solved 4 blocks since I started.

There is a way, but I don't have the technical knowledge to implement it at the moment.

I am busy writing automation scripts that will garner more Bitcoins via trading than by using my ASIC miner. I just finished the first few rounds of testing and the results are promising. I expect that I should be able to supplement the BTC gain/loss due to increasing difficulty.

Sounds about right. There is a bit of variance you have to expect - you need to average your earnings over at least a week - preferably two - before you can make a really good comparison. To make it simple you should only average earnings for a given difficulty.

It seems to largely depend on pool luck if I understood correctly. The Avalon ASIC is my first entry into BTC mining. I am a newbie. I just noticed the stats on one page say that the miner has solved 4 blocks since I started.

Good work!

[jerethdaminer]

while im not expecting to make mega money as i understand gpus are goin the way of dinos
(always my life in when something changes )

im hoping my new gpus will at least earn me enough to break even by years end  i only need to earn 10btc

[Wompaone]

Hey guys I'm new to the pool. Mining with a GTX 650 at a whopping 14MH/z. Just getting to grips with everything and thought I'd stop by and said hey!

[tralala]

How can I manually start a payout on slush?

[OlgaA524]

How can I manually start a payout on slush?

I don't think there is manual payout and 0.05 is minimum so you got to earn it first...

If you want a controlled payout (at certain time) - then set auto payout to large amount and when you ready to get payment lower it to the amount you have.
