Basic BIP 38 is pretty simple if you can use SCrypt and AES256. But the second part of BIP38 what describes keys multiplication is more complicated but is very powerful. Check how bit2factor.org works and what it offers. It's gives amazing possibilities never seen before. And yeah, many people can write an simple web page or an hello world but unable to understand more sophisticated topics as elliptic cryptography which is required to create any bitcoin implementation from scratch. btw, BIP 38 (the second part is about the same scheme as Shamir's)

And there is another issue - in case your tx stuck, in most (in all?) clients it is not possible to increase fee. It can be done by sending same tx with different fee, but why there is no such option?

Rich people usually knows how to detect scam. Sorry for your loss, but it is a good lesson for you. i'm not dumb , i'm rich and I wanted an investment for fun. Not knowing much about bitcoin. And I really wasnt prepared for a scam . You can think whatever you want to think
5k euro is not much for me , but its not fun losing it to a fucking scammer!!
If you are really rich and want to play risky bitcoin investments - let me know. |

When you say "this would be a massive problem if there were any way to use the public key as an input to crack the private key (or use it to verify)..." do you mean that there is a way to use the public key to crack the private key? Does this relate to the advice I have read but not quite understood the reason for, that paper wallets should never be re-used? (putting to one side the "change" issue which is a separate point)
There is no way to find private key when you know public key (it means that ECDSA is not broken). Bitcoin private key is protected by ECDSA, and public key is protected by SHA-256/RIPEMD-160. When you do a transaction, you publish your address' public key, so the address becomes protected only by ECDSA, what is still perfectly safe. |

Thanks for the info! I don't get why sending my coins takes so long. For those of you still waiting for August order kits refunds for late delivery, I just got email from Kat, saying that Dave plans to do refunds by the end of the month. I'm assuming it is end of this month.
Order#149 - "August" Starter kit
Thanks,

Hello all. I still haven't received payment for delayed kit. Why? We ran short of M-boards due to the factory shortage of parts I mentioned. I had hoped they would pick up the slack in production, but the break in production was felt last week when the shipment finally arrived from AK customs with no M-boards. According to tracking, we only expect 12 tomorrow. Every starter kit we send out takes 16 slots from the mine. We have 54 starters left to ship. A cost analysis shows that we would lose over 20TH if we ship out of the mine - taking over 800 cards out of the picture, which does not work well from a financial perspective. The solution is to dedicate four rigs to a separate mining account and then send each customer their share of the coin once we ship. Of course the customer will not pay a hosting fee or their share of power. I have already repointed the hashpower to this dedicated account: https://www.btcguild.com/api.php?api_key=23fcc6a0f8292fe394b1706da8c0d304. As soon as we ship these units, we will distribute the coin accordingly. Thanks for your patience on this - please look for an email requesting your payment address before you send it to us. Best, Dave So your using the M-Boards that were allocated to our orders to maintain your mine (I am an share holder) and you have allocated 4 rigs at BTC Guild at the PPS rate (as per the API) with a 7.5% fee((1 / Network Difficulty * 25) - Pool Fee (7.5%) https://www.btcguild.com//index.php?page=support§ion=howamipaid one of the highest pool fees out there). Seems to me that your failing to walk your talk to ship out August orders before populating your mine. Let us not forget the rigs going to LabRatMining (which I am a shareholder also) which were purchased after most August orders were placed. A cost analysis shows that we would lose over 20TH if we ship out of the mine - taking over 800 cards out of the picture, which does not work well from a financial perspective.
This could be considered a grave financial impropriety. Please enlighten me as to how that is adventurous to us, seems like we are funding the operation of your mine with our equipment and getting paid way less than our own individual strategies. What advantage is that to us, are you sending extra h boards to compensate? Because the BTC payment based on your decisions seems way unfair and you are profiting way more by holding our equipment while the production errors are catching up. Even now, we will not be able to achieve any ROI http://mining.thegenesisblock.com/a/9373700bafYou apparently have the equipment as per your analysis. I know I paid the full overnight shipping fee for an August starter kit. If your taking 800 cards out of the picture by shipping out our paid for equipment, we are getting Avaloned and your decision to do this without asking those of us waiting for orders is a poor choice. You were doing so good, what happened to you. wow, you're right. The pool is PPS with 7.5% fees, which is absolutely insane. furthermore, the current hashrate looks to be around 18Ghash per starter kit (if there are 54 as claimed). I don't mind my order being hosted until more m-borads show up, but i feel like the choice of pool and bare minimum of hardware allocated to it (i saw it get as high as 27Ghash and less than 18Ghash, which indicates it is at a loss compared with the starter kits' extra EOL card that ensures 25-35Ghash for those already up and running at home) People who are mining with starter kits at home are producing almost 150% the bitcoins that this hosting does because of the >=25Ghash speeds and low fee pools available (seriously, 7.5%?) I respect everything you've done dave, but this is a pretty blatant mistake. Punin shipped every single august order within about 3 days using extra h-boards and V2 M-boards. Hopefully we can get an update soon Hi guys. I am working with Dave in some capacities. We do not want customers to feel slighted by the decision not to ship M-boards we had on hand. In this case, we were forced to consider the small impact of shipping M-boards to customers who we can compensate versus the very large impact on the other customer of MegaBigPower(100TH/s mine) who we could not compensate for the loss. I discussed these issues with him, and he has cleared the following: We will pay out based on the theoretical maximum hash rate that the boards would have produced at 25 GH/s, starting from the time we had the M-boards ready to ship, but decided not to ship them. We will calculate this based on the following formula: ( Number of 1-difficulty shares produced over the duration * per-block output ) divided by difficulty at the time they were produced. By my calculation, 25 GH/s should produce a theoretical 502,800 1-diff shares per day or 5.8194 1-diff shares per second. We will count the per-block output as 25.3125 BTC, where 0.3125 BTC is a good high estimate of the fees included on blocks today. We will not charge a fee or power cost on this. This is a short-term solution while we have a shortage of M-boards. As soon as the M-board shortage is rectified, which should be in a few weeks at the latest, we will ship the remaining orders to customers. We hope that this resolves the issue in your minds. We are focused on providing the best customer service we can, and that includes making smart decisions for the 100TH mine customer, who are also severely affected by these delays. In addition, Dave informed me that only 36 orders have not shipped, not the 54 he mentioned before. As Dave said, the team is working 14 hour days nearly 7 days a week to get these issues resolved. Even last weekend when the team went home for a weekend break, someone was working both Saturday and Sunday. We also have more people coming on board soon to continue making rapid progress on all of the difficulties that arise from this type of work. |

I have not heard anything about the mining income for delayed august kits, even though it looks like at least one person has (based on a quote about 2-3 pages back).
i'd love to use the income towards a future purchase, especially if there are any discounts or similar for returning customers. even a bonus EOL board would be really cool. (im a little jealous that many of the first half of the august starters got 25-35ghash worth from 2 boards :p)
Its comin'... It's coming pretty slow. |

That's cool, thanks. So what should I do to setup it? Does it come with instructions?

This is something we (now) have to consider, if you already hadn't. In the interview a few weeks or month back on Let's Talk Bitcoin with the computer scientist who discovered the low entropy of the android based random number generator that was generating 9 bits (and not 256, if I remember correctly) of entropy he stated he found 2 points of weakness and it was VERY suspicious to him.
No, it was 64 bits of system wide entropy. It is quite different thing compared to 9 bits. |

You can get hacked by Alzheimer's. Make sure to save paper backups still. You still have to remember where do you keep the backups  |

Oh, you are about an encrypted wallet. It's correct.

The only keylogger possible on a not rooted phone is keyboard, so it is pretty safe to use default keyboard. And it is much easier to have offline small android than an offline PC/MAC.

This is what I did, too. But it is a bit more technical than the original steps 1. to 4. Like the OP I am not a computer wiz. The additional step took me a couple of hours to sort out. You have to find out what Ubuntu is and what version to get, download it, get the computer to boot off it, work out how to run bitaddress.org via Ubuntu, and finally get the printer to work with Ubuntu. The last step was particularly frustrating (!!!). Definitely safer though if the OP has time and is not computer-phobic.
It can be done more easily and safer - take paper wallet for android and write down a generated key. Just make sure that device is not rooted to prevent external access to app memory. Oh, and the minikey could be tattooed faster and more easily than a QR ;-) |

Okay...
so did any of the AUGUST PRE-ORDER GOT THEIR MINERS??/
It is now September 1st...
So, let's see, Dave mentioned that he would be in an info blackout while he tested units for shipping, Yet, you want to act like an shit head expecting pin point accuracy. Please cancel your orders, Better yet, get out of Bit coin all together. Our community will be a lot better off. He informed all of us of issues as they occurred, Yet you want to act like an immature idiot with your lack of understanding. He is doing the best he can. His keeping us up to date is WAY better than anyone else has! Do us all a favor and either be positive of shut the f up. You have shown how much of an idiot you are. Stop wasting our time to read your STUPID responses. Please stop insulting him because of the sarcasm. I prefer you to get out actually. |

BitFury has a large team of engineers all working to deploy boards. There's is a different board design from ours. Different production line, etc. That group is doing pretty well bringing up their hashpower, which you can see at ghash.io.
Our boards have just begun to ship from the factory in China, and we will turn them around to August delivery customers as soon as we can. I've just grabbed three more tech savvy people to help me with testing/rating the boards, so that we can get them in the shipping line quicker.
Dave
I see. So bitfurystrikesback.com/megabigpower.com bought chips from https://metabank.ru/asic and created your own board, right? /Valentin |

No one ever said your order will be on you door on August 31st. I am not a native english speaker, so maybe I have some misunderstanding what does "August delivery" mean. Could you please describe why "August shipment maybe if everything goes well" is equal to the "August delivery" I purchased? Valle, Sorry if I came across terse. The quote you used makes me sound like an ass  Sorry. My statement comes from this post: Dave stated back on Aug 2nd he hoped the first shipments to be out by Aug 31st. That does not mean all of them. But I believe they will be out quick. So far this is the best experience I have had with ASIC vendors. https://bitcointalk.org/index.php?topic=251966.msg2854485#msg2854485Best Regards, Mark Sorry for that, Mark. Thanks for the clarification. Could you share why do you think that it will be out quick? Now I see 100Thash ghash.io what consist (according rumors) of bitfury hardware and that there are "fast delivery" appeared what cost almost 200$, but no August orders have received/(shipped?) yet even with a regular delivery. It looks like the hardware is ready but it is currently in use and they aren't going to send it soon. According to this pessimistic point of view I see no difference between "soon" and "in 2 weeks". I don't want to "hold them at their throat" but it doesn't look good to me. |
