You'd need the virus to attack ASIC now. And to be fair, there aren't many miners that doesn't keep an eye on their throughput. I would definitively notice if something more than a few % would go away...
And its not very easy to hack and infect and propagate such a virus that would work on Linux.
Basically i'd have to say yes it would be more powerful, but no i don't see it happening.
I would agree most asics are behind a firewall. They normally are not open to internet. Also people watch pools pretty close so even if there was a virus asic owners will notice quick. I do think a botnet could mine the heck out of CPU coins. Not sure how profitable but I'm sure this is going on. But again does not compare to asics Indeed, botnet hijacking CPU and GPU to mine altcoin is pretty much the way to go. Doing it on BTC is silly compared to the profitability from doing it on alt coins. I guess many people still don't understand the difference in hash power from SHA256 and all other altcoins, even Scrypt who also have ASIC, it still does not compare. |

then it required zlib.dll, so i'm not sure if its just W8 sucking and not having that dll by default. zlib 1.dll, I think? It should be included with cgminer and bfgminer - probably missing from the custom cgminer binaries package that novak prepared. Should be an easy fix on their end  Have fun! Correct, nice catch; zlib1.dll 5,20 MB (5 457 642 bytes) Maybe bundle it with the windows binaries if that's "legal"? This would make it even more plug and play. Or at least add the zlib1.dll url bellow the windows binaries? |

In my opinion, a constant money supply model have 2 difficulties:
1. Economy always goes up and down, expanding, contracting, eventually getting slower and slower. So if the number of coins will always increase while the economy can not grow forever, the coin have a risk of losing their value in future for sure, thus give people a bad long term perspective Though I agree with this (in general), the always decreasing money supply is not actually much better, since it is just another extreme (and I would say, of a higher order). Economy expands and contracts in cycles, but cumulatively it still goes up in the long term. Therefore such a schedule of emitting new coins seems to be more potentially detrimental than the constant rate of new money supply... But bitcoin isint a typical fiat currency subject to inflation, instead it promote interest into holding it by gradually reducing supply. The sole reason for this is attracting long term investors. If you remove the halving and even double it instead, you just create inflation which would stimulate dumping, devaluing, etc. However counter-intuitive it may look, this is not a good thing long-term, since holding decimates the very base that Bitcoin is built upon. Its value is derived from Bitcoin's utility as a payment system, whereas bitcoins taken from circulation devalue it... Why? What does it decimate? At worse it will deflate instead of inflate, which is not a problem with the infinite decimal Bitcoin can work on. (More decimal can be added) And then you're using uBTC instead of BTC. |

Do you mean bitcoin can be manipulated?
This is not a secret, as soon as you get enough hashing power Anywhere from 30%~ to 80% let you do increasingly crazy stuff over Bitcoin. Basically bitcoin is protected by the cost to attack. Even small attacks have a cost. If someone wants to destroy Bitcoin and they have many millions to throw away to do it, it's entirely possible. I don't see Bill Gates deciding to make a mega center to destroy Bitcoin, or the military to research a super computer that have millions time the processing power of a standard unit. But it's definitively possible to do. Just not economical. |

I have a question?
I just put the new firmware om my S5, but now i have a red light blinking. Is that right??
Thanx,
Beffje
It is supposed to blink slowly when it is flashing/booting. Once it's mining it is supposed to stop blinking. How far are you in the process? |

Wow you'd pay 330 for s5 shipped right now? in a couple of months they will be 200 or 1 btc I think. S7 impact will be huge! I my self am also looking to add 20 pieces of S5 Miners but I will wait at least for the panic sellers, when diff goes up 10 % or more a couple of times after each other. I live in the EU so no competitetive advertising or anything  If S5 offerd to me I have to check numbers with diff increase 5% (could be more) and then it is hard to make a profit even with free electric And now a bit less. With all the announcements with the competition to Bitmain being made, it look like within a month or two, we'll have another hardware war on our hands. With this being said, this would equate to a sharp difficulty raise so, right now i'm not even sure i want to pay 0.22$/GH. I might still be interested in a deal like two (v1.91 PCBs) S5 for 500$ if its like already in Canada or shipping cost is eaten. But i might very well just wait for panic sells since sellers at the moment seem to think like they're gods right now and don't need to make an effort to sell unless you "make them worth their while". I guess it's still a seller's market but with the hardware coming, we'll be looking at S5's taking S3's position. S7 taking S5's position and non Bitmain hardware take the lead or maybe Bitmain will come up with something interested labeled S7+ or something. |

I can remember buying a pizza with the help of bitcoins but not directly using btc as a form of payment. It went through an intermediary service who processed the order for me and the pizza went to me smoothly. It was my mum's birthday yesterday. And I wanted to buy a birthday cake for her, but when I reached the bread shop, I realized I forgot carrying my wallet and I had only a few bucks in my pocket. I tried to talk to the boss of the shop if I can pay by bitcoin, to my surprise, she said YES and finally I paid the cake by bitcoin.  This is my first time to use BTC as real money buying a real physical goods. As a bitcoiner, using BTC online is very common. Have you ever used Bitcoin as Real money to buy Real/physical goods? plz share your experience. I'm willing to try, but don't know what shop accepts. Why don't you few get a BTC debit card? Basically its a debit card that use a BTC webwallet as its fund. It work just like a normal debit card so it's innately accepted by any store that accept debit. If you find the workarounds, you can use BTC to buy absolutely everything. Getting a debit card is what I'm looking at right now, and it's really promising because I can buy things directly with my btc in just a single swipe. How cool is that? Yes. Exactly. Finally someone listen xD. And online, you can get almost anything by using Bitcoin. Personally i mostly buy hardware and stuff from amazon. Bitcoin usable? Check. Video games on steam? Check. There's sometime so workaround needed. Like right now for amazon i would need a service or a gift card, which is kind of annoying, but it's possible. Mostly i buy from Newegg and Greenman Gaming, Humble bundle, as they all include a payment processor that access Bitcoin and pay them direction in cash. So i could see Amazon accepting BTC directly or indirectly in the future as well. |

Have you got any replies this week? I am wondering what you final setup will look like after all the ideas we bounced at the wall. Please keep me posted, i'd be up for more idea bouncing if you ever meet some technicalities that need resolved~
Red tape. Never fast. I will most definitely keep all of you updated as things progress though. What I've gotten down so far from the dept head is to have a write up on the blockchain, some sort of screen showing blockchain activity, miner activity, operating characteristics (voltage, GH/s) and some other stuff in that same direction. I've got to go in next Wednesday for their weekly department meeting thing and present it to the rest of the faculty to get the final go-ahead. So that means a write up on the blockchain and its relevance to modern society and the future of the financial / security industries. Nothing too fancy, just a way to make things relevant. Maybe you could display this fancy block explorer live; http://chainflyer.bitflyer.jp/You can change the language to English by clicking on the Cog. Explain that each gem that fall is a transaction that just went through, live. Etc, there's many blockchain explorer. Not sure if you have to display it live but you could, maybe even on a small LCD screen showing live blockchain transactions.. Basically the aforementioned website is the same info displayed as https://blockchain.info/ but more "eye candy" i suppose? |

Virosa, /etc/init.d/cgminer.sh
Thank you! Look like the guide to install smit's worked tho. So i get a nice 2800-2600 RPM now. And i manually installed cgminer 4.9.0. So i'm messing with voltage now, look like even though its not the PSU that came with the machine (That one died according to the original owner), the replacement he got is the same crap. It look pretty unstable, it doesn't even seem to do 0710 at 206.5 without eventually a drop in hash after 20-30 minutes and a few chip drops. snip Which version is it on power? There are the ones that use the pols and the pcie ones. If pcie it's pretty easy to change out (other requires cutting and more time to do) But it's a little bit more power then you need but if on 220/240 I would look at the bitmain server PSU's - https://www.bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 . They are a little pricey but I have been impressed with them. It's not PCI-e. But its not particularly hard to change out, basically the problem i have is i don't have any 240V outlets. And i'm not sure i want to start stripping my electric heating off and do the wiring myself to plug those wires in a 240 outlet because i have no experience with that, its not very necessary yet, i'm supposed to move soon etc. It is something i consider doing once i have moved however. With the blunt fact that i paid 400$ for the S4, i don't really feel like paying 200$ to get 300 more GH from it... Unless some nice deal fall on my lap, i don't think i will be changing the PSU. I'm planning on running it just under its max load of 1440W so hopefully it wont crap out before i'm done with it. |

In terms of hashnest and other internal Bitmain mining facilities, I expect those folks received their S7 boxes in the last couple of months. Wherever they were selling used S5's from, had already received an S7 replacement.
Are you saying that the worst hashrate spike is behind us? Probably not, it's highly likely Bitmain will ramp up production and drop the price sharply on S7. I speculate on this because other companies now came up with a retort for the S7 and i'm afraid Bitmain is going to have to beat them in quantity over quality with a S7+ or such. Basically Spoondoolies is comming out with a 0.15W/GH, bitfury something even lower. So i'm not sure when they will be available by the unit or if at all but they are obtainable as bulk, so you will probably be seeing resellers sell those to home-ish/small miner operations relatively shortly after their release. Basically what i'm saying is, we're looking at another hardware war and i don't think this could equate to a low difficulty increase in any way. |

As I said the the software is not at all my thing, but I assume there is a file that you can SSH into and edit on the controller board that will have the frequency divider & delay values? Same as there is for the S3?
Rich
Yes. I use WinSCP myself, pretty nice as you can edit everything from your windows computer more normally. Anyhow the json config file is /config/cgminer.conf. Open it and you will see the normal JSON style config. Relevant line is; "bitmain-freq" : "" Example of proper value "bitmain-freq" : "3:393.75:1f06". Am away from home but took a controller board with me and have just got round to SSH into it. Have found the line you refer to above and as far as i can see the first character "3" is the delay with "3" being around 10mS, this number increases as you drop the frequency and is 10 when you get to 100MHz. Second number "393.75" is the frequency however I think it might just be the text that appears in cgminer? The third Hex number "1f06" is to set up the divider and corresponds to the data in the BM1384 data sheet. So I think this is where the current selected Frequency and associated setup information for Delay and Divider ratio are stored? So yes editing them will probably allow a different frequency to be set. However there must also be a file somewhere which has the complete table of frequencies and with access to that an additional Frequency, Delay and Divider Ratio could be inserted which would then allow selection from within cgminer? Question is does anyone know where this table is? Rich I think not, you would have to use the table we already have and do try to manually figure out which delay to set with the hex. It is indeed possible that the middle value is literally "just for show". Since the cgminer use the typical json.config format, there's no need to have a list of code line that you ssh vi edit-freq etc and just #'out the unused line. I understand what you mean there should be some dictionary for the firmware to automatically change it but i never found it and it might be compiled in the image in boot at start, as such you could try to open image such as cd/mnt/mm1 initramfs.bin.SD for the S4, but for the S5 seem even more elusive. I don't know where it is. Perhaps someone could elucidate the mystery or give a hint but checking file by file is tedious and i did not manage to find anything relevant. =/ Also for the step down, is it possible to put 2 in parallel or something to allow something like 200w~ per blade? May sound expensive but meh, i'd like something around 11v and i guess if they were adjustable as well it would be a plus, but i don't know how step downs/buck converters work. |

Well, no software changes are necessary with my version, I've put a large range of clock speeds in the web page. If any of those pages have hardware voltage change info, for S3s that ignore the voltage, that may be helpful. Is there any versión for the Antminer S5??  Not that i know of, initially S5s were not undervoltable, but some users found out the latest PCBs, v1.91 that is, can run undervolted. A few oscilliator were added from the v1.90 version to the v1.91 version. This however does not mean you can change settings or pencil mod it, the design does not seem to allow this that we can tell of, the way to run it undervolted it is using an adjustable PSU, ideally within the 9.5-11.5 volt range. |

Hello, so i finally received my stick. I went ahead and set it up on a hub on my gpu mining rig running on W8. Installing Zadig went smoothly, but then it required zlib.dll, so i'm not sure if its just W8 sucking and not having that dll by default. Ultimately i had to go to the zlib website and get the dll intended at like windows 2000 or something, i slapped that in system32 but that didn't work, tho putting it in the cgminer did the trick. All in all it was pretty simple to setup, 4 of the 5 minutes was searching and placing the zlib.dll where needed. Now the stick has accepted share. In the event someone else try to set it up and get the error, this report might help them, also the website i got the dll from is; http://www.zlib.net/ |

If you remove the halving and even double it instead, you just create inflation which would stimulate dumping, devaluing, etc. I'm not an expert, nor can i see in the future of eventualities, but regardless, i very much doubt consensus would be reached to reverse something that is accepted as a fact, hard coded in and even looked up by most people because of its alleged price raise that it will bring. Basically if you removed this feature, you'd just be creating another bitcoin fork a.k.a. "Altcoin" and i very much doubt there's much interest in the main bitcoiners into jumping boat (as you can tell by the coin's market caps vs existing coin that went with your idea). |

see with the rising electricity prices i dont think investing in asic miner is worth now.....rising electricty prices is covering up the block reward now.. so its hard now.....however if block reward is increased then it may work...
Could you explain what you mean by "rising electricity prices"? Prices here are not rising at all and at a good electricity rate, the current difficulty with current gen hardware is not much of an impact on income. Thus beside the overpriced unit that is the S7, there is no problem at all with home mining unless you can't have your hardware placed somewhere with a good price for your electricity consumption. well my elec bill shows like 8c kwh when i figure out the bill from kwh's used and the $$$ paid it is always between 13.1c to 13.7c kwh (it varies) there is always some kinda adjustment to taxes/fees/seasonal adjustments and what have you ..always in the upward direction...so best I can figure my price per kwh has gone up between 1.5c to 1.7c kwh just since jan 2015 so it is misleading to say the least just saying Ah i see, the prices here have been pretty static, then again its Government owned. But now that you say you pay 13.1c to 13.7c, i'm afraid to agree that it would be hard for you to see ROI with pretty much any hardware at all. Even cloud mining's overpriced 0.08/kWh would be better for you, and those generally barely break even, so i think mining at home is not for you =/ |

Bitwisdom still does not seem everyone has gotten their S7's
Bitcoin Difficulty: 59,335,351,234
Estimated Next Difficulty: 58,800,027,102 (-0.90%)
Adjust time: After 985 Blocks, About 7.0 days
Hashrate(?): 445,562,864 GH/s
I keep expecting to see it and a big jump. But has not happened yet.
Beside, i doubt that the first batch included thousands and thousands of S7s. By that i mean 1000 S7 is still only 5PH/s, so its not even 1% raise. It might have been only hashnest that received 1k unit and there were a few more thousands units sold and shipped but that sound a bit of a feat in 10 days, so i'm guessing it would not be something like 5% raise just from Batch 1 S7. Did someone work out how many S7 orders they took by following the blocktrail? |

There were 1000 S7 miners.They are just out off stock. Does any have an idea when the sales will begin on Bitmain's site?
Probably not until after S7 hash starts trading on Hashnest, and then restock late October. You can still buy an S7 to hash at https://www.hashnest.com/hash_currencies/25/shop stock remaining is over 800. I don't know but i hope you're wrong. I and many of us still have coupons that expire mid October. Would be pretty annoying if we're unable to redeem or trade them because they aren't reopening sales for a month. Personally i was expecting they would re-open as soon as they're done shipping, so anytime until sep 31. I guess that won't leave a lot of time to find a use for our coupons... |
