The Harvestcoin P2Pool server has been shut down per my previous posts. Thanks again to all who supported it.

F.

Just another reminder that Harvestcoin will be shut down this Friday 13th September at 9am GMT.

Thank you to all who have supported.

F.

Thanks SirMintALot! Appreciate the support!

Thats somehow sad, I always liked your pool 

Due to a change in personal circumstances, I will shutting down Harvestcoin next Friday 13th Semptember at 9am GMT.

Thank you to everybody who has chosen to mine here...it's been a fun journey!

F.

Thanks for the vote of confidence Jesse11!

Good to hear your alright Furball  , I'll mine some more in your pool after I receive more ASIC Miners. Jesse11

So sorry for not getting back to you sooner Jesse11! I was away on holidays with my family and was finding it hard to get to Wifi etc. Hope it didn't cause you too much hassle!

I'm back now and have updated Harvestcoin to the latest versions of Bitcoin, Litecoin and P2Pool and all seems good.

Again, sorry for the delay and I hope you'll reconsider mining on the pool again.

Cheers,

F.

Hey Furball, What's going on with your Pool? Is everything running alright? I'd like to mine some more in your pool to buy more USB ASICMiners but your pool did not pay me for a full 8 Days so I moved. Are you alright Furball? Jesse11

Hey Furball,

Thought I'd jump on and say hello, and ask a few questions. I'm new to mining (and btc... and this forum!) as of June or so, but have been mining on harvestcoin pretty steadily because of no-signup and that you were running litecoin mining on the same pool.

I started with a free 68XX series radeon card I got at work, a free AMD A10 5800K processor & MoBo combo I got at an AMD fan give-away, and a $100 media case & power supply from goodwill. I pointed it all at your litecoin miner, and got a first taste of money from the terminal line. Mmm.

I bought a lot of 10 USB block erupters & hub to run them, mined with them on harvestcoin while I was trying to turn them around on craigslist, and sold (9) of them in USD to break-even. Now I have the radeon card & amd processor, (1) USB block-erupter, and a 9-port Anker hub & usb fan, for the cost of my case & p/s.

got an offer to buy another (10) usb miners at 0.11 btc per, so ponied up a little bit more cash. After the ~0.6btc the first (10) Erupters had mined while I was waiting to sell them, I needed to buy another 1btc or so to cover shipping, etc. Now I'm in for ~$200US, w/ ~3.75 G/hash in hand before the end of August.

Still debating whether I want to sell the additional miners while they're inflated in value, or just take the ride in mining while the USB sticks are still able to produce. I'm in low enough I could actually see break-even, but the opportunity cost the market is providing me with for these USB miners right now is... quite measurable. I'm thinking the most profitable thing to do would be sell the Erupters and buy coin or direct shares of a larger mining pool. That would be less fun than watching the returns through harvestcoin, though, and I am doing this for fun...


Enough waxing idiotic about my setup, my questions!

is it preferable to use different BTC addresses for different bitcoin miners? for instance, I have two separate terminal windows running cgminer, as I have two separate sets of devices mining that require two separate command strings for optimal performance. Would it be advantageous to generate new receiving btc addresses for each of these command strings? reading around on definitions of a P2Pool [1], it says that each miner is set up as a node of that pool, got me thinking that different devices trying to mine on the same node might be "bumping into each other", effectively. Thoughts?

I have noticed very large discrepancies in the TIMING of payouts (obviously between mining w/ 3 GHash vs. 500MHash, but also in holding to a regular rate). Is this just inherent in the structure of P2Pool mining? Am I effectively 'waiting for a block to be found' when I'm seeing spells of non-payment? Admittedly, I've been bad about turning my miners on & off (moving houses, etc.), so I may also just be observing that 24-48 waiting period compounding with breaks in mining. Thoughts?

On your 'pool stats' page, you show a 'local rate' graph, and value listed. What is this rate? I'm only mining ~500MHash/sec, but it shows 1.03 GHash/sec as local rate. Is this 'local' as in miners on a shared node? Am I being grouped w/ somebody? Just wondering how it all works.

Thanks much for the easy-to-use mining pool. If I end up keeping my miners, I'll shoot you a healthy tip when I hit my total break-even (at $200 USD in, should be quick!), and if I sell them I'll do the same.

Hi there,

The payout figure on the stats page is actually an indication of how much me, as the pool operator, will be paid if a block is found right now. As you can see it's been a while since I've received anything from running the pool.

If you're interested in finding out how much YOU will be paid if a block is found, click on the graphs page and find your address; if there is a thin line on the second graph below your address this means that you have a share accepted and it shows how much you will be paid when the block is found.

As regards your question on multiple cpuminers; yes, you can run multiple miners on different PC's and use the same username and password; your total hashrate will be calculated from the hashrate of each miner put together.

Hope that helps, let me know if you have any further questions,

F.

why Payout if a block were found is 0 on your pool these days?

also can i run multiple cpuminer on different pc with the same Username and password from different pc's ??

Ha, yeah we're screamin' along!  I guess Bitcoin mining on P2Pool has taken a hit over the last few weeks...hopefully it will go up again soon.

Litecoin mining is on the up though! 

Mean 1.08 GH/s   

To all Litecoin miners on Harvestcoin;

Litecoind has been updated to version 0.6.9.1 on Harvestcoin to avail of the lower fee feature in the latest release. Keep a lookout for the general public release to upgrade your wallet.

Indeed there is! If you're looking for some reading material, this is a great guide to mining on sites like Harvestcoin written by somebody on this forum, well worth the read.

https://bitcointalksearch.org/topic/a-guide-for-mining-efficiently-on-p2pool-includes-fud-repellent-and-faq-153232

It's LiR6rS9pjUJBx4Cbc5yg6ZCU95ywXoi7Ef, but I only tried it for a few hours.  I probably won't run it for long until I figure out how to raise my Hash Rate.

I'm using Ubuntu 12.04 and I have a Radeon Sapphire 7870.

I tried a vanilla cgminer command with no flags (except the server, login and --scrypt), and also tried a few other things I found posted in various forums:

-p 1234 --thread-concurrency 8192 -g 1 -w 256


I only got my hash rate above 20K when I put the --Intensity > 15.  Still seemed low.

Anyway, I'm going to keep learning.  There's so much to read!!!

I wouldn't worry about being new to it, I think we're all still learning!! 

When you mine on Litecoin your hashrate changes from Mh to Kh but I wouldn't expect it to drop that much...mining Litecoin is slightly different to Bitcoin on P2Pool so maybe use the default settings on your miner and not necessarily the flags that I gave you for Bitcoin...they work well with BTC but LTC is a different kettle of fish.

Whats your Litecoin address? I'll keep an eye on the stats for you and see if I can help anyway.

F.

Thanks for the detailed reply, I'll give it a try.  I'm new to this and I'm mostly having fun learning.

Perhaps you can refer me to a good introduction to scrypt mining.  Should I be alarmed that my hash rate goes from 380M to 20K when I try litecoins?

There's tons of information out there.  I've been a little slow sorting through it.

Hi RangerK,

Due to the way P2Pool works I would try using these flags to improve performance :

./cgminer -o http://mining.harvestcoin.com:9332 -u xxx -p xxx -Q 0 -g 1 --intensity d --gpu-dyninterval 50

I know the general consensus on mining is get your intensity as high as you can go but with P2Pool it works better if you change it to dynamic, so I would give the above options a go and see how you get on.

Also, it is common for it to take some time to see payments come through on P2Pool, so give it a good 24-48 hours of testing before you make any decisions on it.

Just to make you aware, mining Bitcoin has become harder recently with the difficulty increases and P2Pool nodes are seeing some "bad luck" in the last week or so...not that I'm trying to discourage you, there's still lots of "dust" to make! ;-)

Here at Harvestcoin we have seen people migrating from Bitcoin to Litecoin as the "luck", difficulty and network hashrate is still very consistent and miners are getting consistent payouts. Again, I'm not trying to discourage you but I would just suggest you give things a go and if its not what you hoped for, you could try mining Litecoin on Harvestcoin instead.

Let me know if you need any further help.

Cheers,

F.

Certainly, and thank you for the prompt reply.

1. Bitcoin
2. cgminer with the following command:  ./cgminer -o http://mining.harvestcoin.com:9332 -u xxx -p xxx -I 15 --temp-cutoff 75
3. about 25% rejected

Hi RangerK,

Thanks for trying Harvestcoin, appreciate it.

If you could give me more information about your mining setup we can try and get you mining more efficiently :

1: Which coin are you mining? We do Bitcoin AND Litecoin at Harvestcoin.
2: What miner are you using? I would suggest cgminer if you're not already using it; I can suggest some configurations which will help you mine on Harvestcoin.
3: What percentage of rejects are you getting? This could be a miner config issue, so the information you provide in number 2 above should help us sort that out.

The "Stratum from pool 0 requrested work restart." is perfectly normal on a pool such as Harvestcoin as it uses server side software called P2Pool and this is a standard message from this server; it does indicate any issue with your mining setup.

Thanks again for trying it and lets hope we can get you mining well.

F.

Newbie miner here.  I'm still figuring things out.

I love the simplicity of your website.  Beautiful.

After I connect, I get more rejects than accepted.  Is that normal?

Edit: also, almost constant "Stratum from pool 0 requrested work restart."

Harvestcoin is now running the latest and greatest Litecoind with reduced fee support.

To connect, point your miner to
http://mining.harvestcoin.com:9327

and use your Litecoin address for username and anything for password.

Happy Mining!

To all Litecoin miners on Harvestcoin; I will be building the new version of Litecoin soon and restarting the server to avail of the cheaper fees changes.

Will let you know when it is complete.

F.

Have noticed a bit of a shift towards mining Litecoin on Harvestcoin. If you've traditional mined Bitcoin but are frustrated by the increase in difficulty, please feel free to try mining Litecoins at Harvestcoin.

Point your miner to :
http://mining.harvestcoin.com:9327 and use your Litecoin address as username and anything as password.

Stats for the pool can also be found at the above URL.

Thanks and happy mining!

Thanks for giving it a go...just be aware that when you're mining on P2Pool it is worth giving it a good 24 hours of mining with a decent hashrate to accurately see what sort of payouts you will get. The Litecoin P2Pool is finding blocks regularly so once you get a share accepted, you should payments coming through...just takes a bit of patience.

Cheers.

Thanks for your help. I'm sending my gpu miner to your pool for a while to see if my hasrate is too low.

Sorry, just realized that you were mining Litecoins, not Bitcoins...so just ignore the last part about the network difficulty...was thinking about Bitcoin there...but the other advice still stands.

Cheers!

First of all, thanks very much for mining at Harvestcoin!

Yes, you are right in what you say that your hashrate is probably the reason for the slow payouts. If you look at the second graph you will see a short horizontal line which indicates that your miners managed to get a share submitted and then during that period of the line being present, IF a block was found by the entire P2Pool network you would have been paid that amount.

As you can see the line disappeared later on, so that meant that the share is no longer valid and even if the pool finds a block, you will not receive any payment.

I would suggest that you try and increase your hashrate to try and get more shares submitted in P2Pool..have a look at other miners hashrates and how it affects the payout line in the second graph.

Also, we are in a strange bad luck time right now across the whole P2Pool network where very few blocks are being found...could just be a phase or might have more to do with the network difficulty going up recently...still not too sure.

Hope that helps somewhat.

F.

I know I'm currently only having a very small hashrate because of cpu mining with the litecoin wallet, but somehow this looks strange to me:

I'm not getting any payments since 2 days, but my hashrate hasn't changed...

Just a quick reminder to the people who are mining on Harvestcoin(thank you by the way!), to reduce DOA(Dead On Arrival's) please tune your miner(cgminer/bfgminer) with the following options :

-Q 0 -g 1 --intensity d --gpu-dyninterval 50

Because of fast longpooling in p2pool it is better to NOT fetch work ahead. Dyninterval sets the maximum amount of time a GPU should be blocked, it's set in milliseconds. 50ms is a good compromise because the hashrate is still good and the maximum blocked time is still less than 0.5% of the share interval of P2Pool so can't influence its efficiency much (theoretically at most 0.25%).

Thanks to gyverlb for this recommendation... see more in his excellent guide at https://bitcointalksearch.org/topic/a-guide-for-mining-efficiently-on-p2pool-includes-fud-repellent-and-faq-153232

By us all tuning our miners we can have a more efficient pool and hence more profitable! Thanks!

i'm using cgminer
i have already tried those settings, and they reduce my hashrate a bit, which is ideal with intensity =7
anyway i'll test it, for 24 hours, thank you

14% isn't too bad but could always be better...at least it is lower than the overall pool rate, so shouldn't affect you.

What miner are you using? P2Pool can be picky with miner settings. If you're using cgminer try using these flags to improve performance on Harvestcoin :

-Q 0 -g 1 --intensity d --gpu-dyninterval 50

Also, it is common for it to take some time to see payments come through on P2Pool, so give it a good 24-48 hours of testing before you make any decisions on it.

Thanks again for trying it!

i'm just testing p2pool without having to setup a node

btw i have 14% reject, is this ok?

Thanks for mining here, appreciate it!

The fee is 0.5% and can very verified at http://mining.harvestcoin.com:9332/fee

If you have any comments or suggestions please don't hesitate to ask.

F.

ok, is there now

just to know, how much is the fee?

Whats your address Amph? Will check it here...

i'm using my address for my user, but it doesn't appear between the other, why?

Thanks for sticking with it mepsipax! Appreciate it!

Hopefully we'll get you mining quickly and reaping in the coins! 

I am off to work now, so will try to join again later.

I am pretty confident my settings are fine, as I am able to connect to other pools successfully.

Am running the 12.8 drivers for my card, as recommended on Bitcoin.Forum, and yes I have tried rebooting loads!

Thank you for your help, and I will let you know if I manage to fix this 

Yes, those 'stratum from pool 0 requested work restart' messages are perfectly normal and you should see those approximately every 10 seconds or so when you are connected to P2Pool; so in my mind it looks like you are connected to the pool alright but your GPU has not been initialized so you are not actually mining the work that the pool is sending to you.

I'm guessing you've done the usual things like, made sure you have the most up to date GPU driver, rebooted etc etc...sorry if that advice is beneath you! ;-)

Hi 

Oops yes I meant mhz not khz 

Ok I transferred your settings to cgminer, but now I get 'Failed to init GPU thread 0, disabling device 0'

then - 'Restarting the GPU from the menu will not fix this'

'Press enter to continue'

Once I press enter, I then get lots of 'stratum from pool 0 requested work restart' messages.

I appear to be connected, but not mining, and have a zero hash rate.

Hi there,

Yes, so you're spot on that you're not getting registered with the server. P2Pool can be quite picky when it comes to miner config so can you try running your miner with the following setup? (I've added your address in here so you can just copy and paste the whole thing)

cgminer -o http://mining.harvestcoin.com:9332 -u 1ATvkkwAHAT6ceFpi2z27UEFe5DPMQ2VxC -p 123qwe -Q 0 -g 1 --intensity d --gpu-dyninterval 50 --auto-fan

Also, did you mean Mhz rather than Khz? Mining with BTC tends to be measured in Mhz whereas LTC and others are measured in Khz.

F.

Hi 

My BTC address I am using is - 1ATvkkwAHAT6ceFpi2z27UEFe5DPMQ2VxC

I am using cgminer

Additional options in cgminer - thread-concurrency 8192  --no-submit-stale --intensity 13 --worksize 256 -g 2 --auto-fan

My hash rate isn't that great atm, due to the warm weather, and my wanting to keep temps down on my 7970 Dual-x  (until I sort out additional cooling), so I am using default settings, not overclocked, and getting about 480khz which is about right I think.

I am with Virgin Media UK broadband 120mb wired ethernet

Many thanks

Thanks for getting in touch mepsipax, lets see if we can get you sorted. Can you answer a few questions below?

1: What BTC address are you using as your username?
2: Which miner are you using? cgminer/bfgminer etc
3: Are you using any options in your miner other than the basic setup as described on harvestcoin.com? If so, please include them.
4: What sort of hash rate are you expecting to see?
5: What sort of internet connection are you using?

Hopefully it's something very minor and we can get you mining quickly.

Cheers!

F.

I am not sure what I am doing wrong, but after mining on your btc pool for two separate 8 hour shifts, I am not detected as mining on http://mining.harvestcoin.com:9332/.

Followed directions to mine carefully (have been mining successfully elsewhere bitcoins and litecoins) and used this guide http://www.harvestcoin.com/ which was straightforward.

Should I have installed P2Pool software before mining?

To add:  I get a reasonable hashrate, though the second time I mined, I received quite a lot of rejected shares - though a lot more accepted ones.  Otherwise, all looks well when mining, but as said previously, there is no sign of my miner on the p2pool btc.

Advice appreciated

A big thanks to all the miners who are starting to use Harvest Coin for their pool!

In an effort to raise the income of miners I have increased the blockmaxsize setting to 1000000 to include more transactions in the block, so hopefully people will see a greater income for their hashrate. I am also tuning the mintxfee to keep latency low and improve efficiency.

If anybody has any comments or suggestions regarding the pool please do not hesitate to contact me.

Happy Mining!

Just sent a small tip through to you...fraid it's not much, but just wanted to say thanks for the comments!

LMbDBgHdXc9tpp79kEPFUFQUezpXf24vzw
thanks!

Delighted to hear it is working well for you cheesylard, its a relief to hear!

You can definitely mine with multiple miners with the same address; it will be totaled up within the system...so if you have 2 miners running at 100mh, it will be counted as 200mh to that one address.

As your the first person to complement the pool, send me your address and I'll fire you through a small tip! ;-)

Maybe you could add an API, so we can see how fast, and how many bitcoins/litecoins we already mined.

No problem. It's been working great so far.

I'm kind of new at this, but if I mine using your node using multiple workers with the same address, will the hashrate accumulate or will all but one of the workers be ignored?

Thanks so much cheesylard, appreciate it. Let me know if you have any questions or comments.

Threw 200Kh/s at it

Thanks Kennji! Hopefully people will find it useful!

Looks good!!
