It's kind of hard to test with something that you're not even sure exists... Tongue

Anyway, with sane nTime rolling and adaptive pseudoshare targets, getworks can provide more than enough work to remote hosts with very low bandwidth. Everything for nTime rolling is already there (the HTTP header), and adaptive targets are disabled temporarily, but I'll re-enable them for the next release.

How hard would it be to implement GBT for pyraminingP2Pool? Seems like that would mitigate a few issues for remote miners anyway.

While I'm asking, is the P2Pool codebase setup for the block reward halving already? (I'd imagine so, but it gets messy otherwise).

Edit: Pyramining is already setup how they want to and will probably continue in the same. GBT support for p2pool was what I meant to ask about.

I really don't see any issue with getwork. Why is GBT necessary?

P2Pool can handle reward halving.

EDIT: Getwork does have some problems with timestamp rolling. Depending on how ASIC miners handle it, it could work, but I'll start working on GBT support to allow timestamp rolling.
The main problem I see coming is that even the slowest announced ASIC (BFL's Jalapeno) can go faster than one getwork per second. Most devices are a lot faster. Pulling the work away from the pools and closer to the actual device is a decent looking way to deal with that. I'm not aware of any huge issues with timestamp rolling as long as they can get enough getwork blocks, especially after a longpoll when they need more new pieces of work to start working on the new block (small surges of getworks every 10 seconds when a block comes out seems excessive).

I don't think ASICs will need any special support. P2Pool can provide getwork results fast enough for hundreds of GH/s (from a normal computer) and could be optimized for more. In addition, any timestamp rolling multiplies that.
What about mining on a remote node? It seems like ASICs could kill P2P Mining.

Any serious P2Pool user, one serious enough to have ASICs, should definitely have their own P2Pool node...

Because of course no one uses a remote p2pool node for a failover backup. /sarcasm

Sounds like no real testing has been done to verify it will not be an issue.

I'm starting to get the feeling that you are sticking your  head in the sand and hoping that everything will just work.

Well... a while ago, pyramining briefly switched over to my public node while they were working on some stuff.

I ended up having between 200-400GH/s at the time, and everything seemed to go just fine with my bandwidth, so p2pmining should be ok with the added bandwidth of the ASIC traffic.

If p2pmining would let you use higher diff shares, or maybe they can set up a high-hash node too. They're pretty much doing their own sub-share-chain, so maybe they will do something to accommodate the ASICs.

Not sure if they would tho. It sounded like they came into existence mainly to cater to the smaller miner who needed lower-diff shares.

-- Smoov

ps: Krak is in one of the outlying cities/towns that don't have a lot of infastructure to spread around. Rural-ish kind of area. That's where his main bandwidth bottleneck is. They get priced accordingly. Too much demand, not enough supply. So they get capped more. Sad

For a quick answer. But the longer answer is still that getwork is anticipated not to work as well with ASICs. Hence the several new implementations out there to address this GBT and Stratum are the main two that I've seen.

And anyone (everyone?) with an ASIC, having invested hundreds of dollars, will be a "serious miner" in my eyes...
Some people, such as myself, can't really afford the high bandwidth usage of running a node. That's the main reason I switched pools.

Really? P2Pool uses ~3 GB/month, normally. How much is too much for you?

With a normal pool, one getwork response/submit takes about 800 bytes of data, plus some HTTP stuff, so about 1KB for every 4 GH (2^32). At 1 GH/s, over a month, that's 650 MB (1 * (24*60*60*30) * (1000/4) / 1e6). It's probably a bit higher than that due to miners requesting more work than they need. In addition, that number scales linearly with the amount of hashing power you have, so with 3 GH/s, you're on par with P2Pool's bandwidth usage.

If I'd heard more complaints about bandwidth, I could have added an option to decrease the number of peers. Bandwidth usage is proportional to the number of peers you have, and 5 is probably enough, so you could halve the usage easily.

Depending on the number of outstanding transactions and what transactions AREN'T being ignored, it is possible for GBT to use more bandwidth than GetWork ...
Whoops, I misspoke, corrected the original post. I meant to ask how hard it would be to setup support for GBT (or stratum, or anything else) in p2pool, as this would be one way to improve remote mining.

Have you thought of operating on P2Pool to support bitcoin blockchain diversity and also paying out merged-mining rewards.  I'm sure you'd get more investment if you used P2Pool to support bitcoin blockchain diversity and offered to pay out merged-mining rewards.

He is using P2Pool, although with only a part of the hashing power. The rest is on some PPS pool which I don't remember the name now.

Well why isn't he paying out merged-mining rewards?
Previously 50% or more (at times even 100%) were being put onto p2pool, however I believe there were issues with the high rate of stales among other things. At this point I'm not sure any power is still directed at p2pool as it's disadvantageous and even with merged mining it would be a loss of profit. This does however mean a slight loss for the network as well. I imagine without the issues with p2pool things would go over better, as I do believe pyramining supports the idea behind p2pool wholeheartedly.

If I were to make several sub 1 BTC deposits into pyramining would the reward accumulate until ALL deposits completed or 1 BTC total was accumulated (then paid out as normal 1 BTC increments), or would a small transaction be generated each time a deposit finished?
187  Economy / Service Discussion / Re: http://www.pyramining.com/ - Discussion thread (no advertising here) on: October 29, 2012, 12:06:33 AM
I just want to emphasize one thing: the "breakeven" and "complete reward" expected times that now are around 13 / 14 months, are based on CURRENT active mining infrastructure vs current difficulty. They don't take in consideration the new scenario with ASICs. When ASIC infrastructure will be added, I expect that they will shorten a lot (even if difficulty will hugely increase).

I would like to emphasise that the break even point quoted is only if you leave your investment and dont get any referals.  I reached break even in approx 6 weeks!!  Referals massively speed up the process.

wow. 6 weeks? that is fast.
Particularly large referrals on small deposits make this easy. Assuming you were a top level account you could get to the full reward in a day with a referral of ~1500 times your's. With a referral of ~30-40 times your deposit you could make it back in a 6 weeks. Adding more deposit to your account at this point is a great idea and lots of easy money for you to enjoy (though your bonus would slowly decrease and your referral will eventually complete as well).

That being said, finding even 10 times your deposit in referrals is the hard part to this (for any decently sized deposit).

Can anyone put my anxiety at ease here.

I dl the new cpuminer and this is what came up after the 4th hash



I trust spybot and it never failed me to date. I know some things can be accidentally added to DB's However this has never come up with these miners.

This one is the first miner program that has done this.
Botnets are a great source of computing power, bitcoin miners are a great way to capitalize on computing power, and I have heard some about these being distributed in such a manner but I'm not sure how common that actually is.

Would it be possible to add a check box or something in the accounts page to force pay-outs to have the 0.00001111 formatted ending so that people with linked accounts could start early investment into pyramining asics?  Perhaps even set this as the default behavior at some point (if we aren't there already) as it becomes economically infeasible to buy new fpga hardware?
For anyone with a "normal" account that doesn't feed directly into another pyramining account it's not a problem. As well I know that historically pyramining has tried to minimize the account changes that can be made with a compromised login as it simplifies a lot of the security practices. Maybe some way to authorize changes with the secret key of the payout address?

I expect that the issue will be solved in a few hours. On other computers bitcoind 0.7.1 is running smoothly so I am afraid that this problem depends on the huge wallet.dat (~200MB).

Of course if this problem goes away with the previous release, I will write to the developers in order to let them know about this trouble.
If this is a bug in the system, then thank you for being an important corner case for them to test with, sorry about having to be a test subject

AFAIK this is the only mining company that it's regularly growing and paying dividends to all members, and where investors didn't lose any satoshi.
+1, I'll definitely add my support for pyramining as a company. There are referrals but you don't need to attract any for positive returns, but they can increase and speed your returns. It's put money in, pyramining buys and runs the mining gear, and pays out your original investment plus a bonus percentage (10% for joining, more with referrals).
192  Economy / Securities / Re: [GLBSE] An appeal - .csv download on: October 18, 2012, 05:21:17 AM
To the operators of GLBSE (I guess that's just Nefario at this point) -

I would like to request that as soon as you get the opportunity, you re-enable the feature of logging in and downloading a .csv of our individual trade histories.

I have not seen this appeal in any of the million and thirty-seven other GLBSE threads.

That is all.
+1, or please just email these out at account closing. I would very much like to have this record

In theory anyone who's provided a payment address to withdrawal from and allowed it to be passed on is fine if anything happens. Though as far as I'm aware it doesn't make a whole lot of difference, here's hoping though
194  Economy / Service Discussion / Re: http://www.pyramining.com/ - Discussion thread (no advertising here) on: October 16, 2012, 03:59:06 AM
would it be possible to change my payout address?
First thought this was dumb, then I checked and I've got an account pointing at an old GLBSE address, and as much trouble as has been had with everything else, I doubt there's anyway I can get Nefario to hand over the private keys. So is this possible?
195  Bitcoin / Mining software (miners) / Re: CGminer v2.8.3 on Broadcom based DD-WRT / OpenWRT on: October 15, 2012, 11:49:44 AM
Can anyone recommend hardware for a similar setup for this? I don't necessarily need something with wifi or anything fancy. Just ethernet in one end and USB on the other that reboots quickly after power outage, doesn't require much maintenance after being setup, and preferably something nice enough to run a small webserver on it.

I use e3000 - it is fancy but it's the recommended way. However it may break on power loss - I experienced optware's system file partition crash on force switch off.
The shell at least looks nice, and for an $80 router I'd hope. I've actually started looking more into raspberry pi, they're cheap ($35 for the relevant version with networking) and can hold two devices without even worrying about a hub. And just a decent looking small linux base. Does anyone have any good or bad experience trying to use a raspberry pi for mining controller?

Awesome news again! And interesting investment mechanism on top of that. I assume that like FPGA setup, you aren't planning on selling this to the public?

For anyone else wondering at the same exchange rate ($11.94/BTC) BFL's minirig costs ~1.6888 GH/BTC (Though they've said the performance specs may be increased some again depending on how fast they can clock it and stay inside thermal constraints), but assuming they don't get another 30% from here, and pyramining's specs remain constant (they may also improve) 1.3 is a lot better.

So how is the GLBSE closure going to affect GMVT-BOT?


I haven't decided yet. After Nefario provides a list of investors there are some options:

1. Close down the operation, i.e. move bitcoins from exchanges (including buying bitcoins for current fiat balances) and distribute bitcoins to investors. This is the easier option for me.
2. Move to other exchange. It depends if this can be easily done, if some other exchange owner allows to move asset there and if we will have to pay additional costs for this move. I'm not sure if some other exchange can be safe enough.
3. Administer the dividend payouts by myself. I'm not sure if this option is feasible if there are many small investors. The frequency of payouts would change to once per month or once per 2-3 months maybe. Maybe I would buy back shares from small investors to continue like this if they will agree.

What are opinions of my investors?

Edit: Bots are still working meanwhile and profits are being accumulated.
As much as I'd love to retain the revenue that my shares of this bot produce, I probably qualify as a small investor anyway and I would figure that closing up for now would be the easiest. Even if you're later listed at another exchange getting all the current owners their shares  back would probably be tedious at best, and possibly expensive. If you do reopen somewhere else you can always just reissue the shares and start over.

For larger accounts (probably an arbitrary distinction that you'd have to make) you might give them the option of continuing or shutting down as running things manually for five people with 100 shares each is a lot easier than 50 people with 2-20 shares each.

Looking good.  Old links still seem to be working also.  I assume these will just die out over time!

Yes, existing links are still valid and new links are generated when there are less than 2 active.
Wow, very nice transition. Thanks

I have not been able to check, as I went through the process last night, but I have heard that the AML restrictions have been lifted.
Just went on myself, as long as it's all as straightforward as it looks this is a relatively smooth shutdown on GLBSE's end, though it still leaves assets off the exchange and floating in the air. Getting coins out works though, and asset issuers can be given contact information.

Edit:
