To arms Bitcoin community! Help us to complete this mining installation for the Zürich MoneyMuseum. We are not asking for funds. Only your expertise needed! 20$ tip if you give us the relevant clue to solve or mitigate our main problem. Nice pictures of the exhibition inside as well…
Edit: A big thank you to all people who helped us we can now mine true pps with diff1! The people in this thread which have helped most have been awarded. I want to mention also the operator of btcmp.com denis2342 and Luke-Jr. Actually looking at the miner screen in the Linux terminal helped a lot ;-). The pool constantly resigned to stratum with variable difficulty. We can now mine true pps with diff1. Getwork with long polling seems to be default after disabling stratum... We will probably post again, when there is a video of the installation in action... Again many thanks. Learned a lot. Edit: Thank you for all the answeres so far! We will try different things now and report back. Tip bounty will be distrubuted as soon as we found out what finally does the trick. Ths could take a few days. The offerd tip will be distributed and very likeley a few others as well. First of all, let me tell you that the Bitcoin Exhibition at the Zürich MoneyMuseum is most likely the biggest and most diverse of it’s kind. Please read more about the museum and the exhibition below. Help us solve the following problem we experience with our “Muscle Powered Proof of Work” installation: Me and a friend have invested a lot of time to build an installation for the Museum. It is basically a 10GHash/s miner and RapberryPi which is powered by a hand generator (Maxon DC motor with planetary gear). Here are some pictures of the installation, although not entirely put together yet. There are still some changes planned. https://www.dropbox.com/sh/0qcvl3wu4romhnt/AAAYF08lnVAy6W6KEepE7e2Ua?dl=0 Now let’s get to the core of our problem: We are mining at the getwork diff1 pool btcmp.com as it is a true pps pool with getwork diff1. The visitors in the museum can power the generator for 2-3min and see directly how many Satoshis the "network" (actually pool but we don't want to confuse the visitors to much at that point) has given the museum for their work. This all works well so far but one problem remains. Sometimes the pool does not get a share from us for more than 40 seconds or even more than 60 in some cases. I have calculated that with 8.4 GHash/s we should find a share about every 0.5 seconds in average (diff1). I think when the pool gets a share it gets all the hashes as it then accounts for several Satoshis. Statistically we get per minute what we should get in theory. We would very much like to lower the time between the accepted shares by the pool, however. This would help to make the overall experience much smoother for the visitors. Please look at this screenshot from MinePeon and answer some questions: https://www.dropbox.com/s/lb1jei4trc9kqe5/MinePeonScreenshot.png?dl=0 We see that we get a lot of diff1 hashes. However, only 11 shares/packages have been accepted. The Is there a possibility to set the miner SW so it submits to the pool as soon as a share is found? It seems to send them in packages which sometimes have 4-5 seconds in between but sometimes a much as 80 seconds. I would like to submit packages of hashes much more often. How can this be influenced? What exactly are the Getworks (GW)? What exactly are the Accepted ones (Acc)? This is where the TipBounty is. Help us to get a better Acc/diff1 ratio. Best would be 1:1. What exactly are the rejected ones (Rej)? What exactly are the discarded ones (Disc)? What exactly are the difficulty one hashes (diff1)? Now some of these questions seem very very basic but it is important for us to understand what these are and how we can influence these. We have a 1:1 correlation between the Acc and the pool side acknowledgement of shares/packages. So whenever the MinePeon shows one more for this value the pool value for last submitted share goes to “moments ago”. Does the miner SW have a setting where we can set after how many diff1 hashes a package of hashes is sent to the pool? If no, do you have another idea why so few are sent? Ideally we would set it so the diff1 hashes are sent every 5 seconds or so, probably even more often. Is stratum with fixed diff1 possible? If so, would it be better to use stratum? Are there critical settings if we should know of? (we have tried --request-diff and --no-submit-stale) We are using BFGMiner on MinePeon if that matters. We could switch to CGMiner if that would help. Any help is very much appreciated. The museum is doing a great job explaining Bitcoin basics. We had special focus on interactive learning and have several things to underline this. I hope to hear back from you so we can improve our installation. Please don't hesitate to ask if you have further questions. We are both not mining experts. Thanks for reading and AMA.

Life screen with various stats/charts/parameters/transactions…
Muscle powered PoW: Hand generator with 5v and 3.5-5A output, Raspberry Pi, MinePeon, 5x Antminer U2+ plus a screen to show the hash-rate at the pool and/or in MinePeon web interface. This screen will not be hand powered. This installation will complement their coining die (go to 1:27 to see what I mean).

I see this as a good opportunity for Bitcoin, so let’s embrace it. I am especially excited to compare the traditional forms of money which used proof of work to the new money which also uses proof of work. I think in that context it will be much easier for the visitors to value this concept. A lot of schools and other groups book guided tours at the museum. It is open on every Friday from December 05. On. Entry is free of charge. Edit:Markdown, typos
Since the evolution of Bitcoin, mining is a great source of income. But anyone has wondered how much energy is required to mine Bitcoin? Is it now worth to do mining? Dago mining works directly looking after energy problems. https://dago-mining.com
Discussion the electricity used by the Bitcoin network and the future evolution of Bitcoin mining
Is there some research available on the subject ? I thought about this after reading that tweet: https://twitter.com/BitfuryGeorge/status/813604111685914624 I hadn't realized that Bitcoin was already consuming 1/10 000th of the top 20 countries electricity production. If the Bitcoin price was to increase dramatically, let's say from 10 to 100k in the next 10 years, the blocksize subsidy would not come down fast enough for the price of electricity to not become a major factor in how Bitcoin and mining develops. My guess of the things we could see:
Bitcoin mining tax (This would have the effect of pushing bitcoin mining away from countries who think they have too much bitcoin mining going on, governments are also very keen to shoot themselves in the foot generally).
Carbon tax (would make sure Bitcoin and other electricity heavy industries use clean energy or move somewhere else)
Market forces favoring decentralisation away from China ? If Bitcoin mining becomes too energy intensive, the price of electricity in the remote regions of China will increase in a manner that will make it more profitable to mine outside of China.
etc.. The good thing about Bitcoin mining is that it can be done in remote places and that being done in very cold places is going to be more and more of an advantage too (as cooling costs increase). For those who read that book "The Age of EM", I think we could see a similar favored geography if Bitcoin were to really increase dramatically (let's say over $100K) with all the mining being done in cold deserted places that combine a potential for cheap electricity. It's also important because it would be badly perceived if Bitcoin were to push up the price of electricity for the general population. On the other hand we can't exclude the possibility of this being used as another PR angle to attack Bitcoin in the future (as the price goes up, the "ponzi" haters ala Krugman, Kaminska are certain to migrate to Bitcoin's energy consumption as their favorite argument). So we better be ready with some factual research to counter it.
