Bleh. What's your use case? Bitcoin uses strong crypto because it's money. But you should still use strong crypto for customer data. What are you trying (not so hard) to protect?
There is this (false) concept called security by obscurity, and it sounds like what you're aiming for here. If someone knows what algorithm you're using, they could easily brute-force these keys. Protected anything of value with it, and you'll get rainbow tables of priv => public keys get published pretty quickly, meaning everyone already has a copy of all possible private/public keys. You can buy 2TB hard disks which have all the possible encryption keys for GSM - which is stronger than what you're suggesting here.
And perhaps you'd suggest keeping the algorithm secret. That doesn't work for crypto - everything about a strong cryptosystem can be known besides the private key in order for data to be secure.
Why even bother with cryptography if you don't care if the data is exposed?
One use case which I think would be valuable would be simply for teaching purposes. If you could find a public-private key pair just to illustrate the old "alice wants to talk to bob" scenario with very small numbers, that would help simpletons like me to understand the concepts better (perhaps). The actual use case is this: Bob is an adolescent male who wants to tell Charlie (who incidentally is now in jail) that he fucked Alice. But he doesn't want anyone else to know. So, he puts this info in an OP_Return output with some light encryption to prevent all but determined snoops from knowing as Alice isn't very good looking and it would be bad for his reputation. |

Why don't people just contribute to core development instead? Fees for mining are necessary. Although, you would have to be pretty advance to contribute to core development, it's still something some people are very much capable of doing.
Even contributing towards development by suggesting and providing feedback is a great way to start. Without feedback from the community, the software has limitations because of the developers wants/needs and their aspirations.
People are capable, but all these capable people left to go earn money doing something else. The core dev team is nearly totally gone on other projects leaving a serious shortcoming regarding the advance of the entire bitcoin system. This notion that 'open source' will attract people to stay up late and work hard for free - just doesn't work. I failed to understand the necessity of Core Development in today's scenario. When Satoshi first wrote it there was nothing else. But today, there are so many wallet softwares around core code is open as well. If someone want, he/she can modify/extend it as well. But, what is the point of keeping a core dev team that would follow the directives of a centralized body which would feed them (Read: bitcoin foundation) ?
Clearly you don't understand Bitcoin. The core remains a bit fragile. It could use some good attention from very smart guys. 'wallet softwares'? has nothing at all to do with the work done by core devs. |

Clearly there is a severe shortcoming regarding funding for core development. Why don't we run "Bitcoin Core: 0.10.1" for a year or two where all miners kick the fees over to salaries for the smartest guys to spend their days working hard on the core? Miners don't really need the fees yet. In about 10 years, miners will live off those fees. But today, miners are well paid (over paid) as it is. So much easy money in mining has caused them to rush out and buy extremely expensive exotic process nodes for radical ASICS. Too much money in mining caused this arms race that went too fast and too furious. We don't need to put more juice into mining rewards. We need more juice in core development. It was an imbalance that Satoshi couldn't predict. But we can easily fix it. All miners should 'volunteer' (by running Bitcoin Core 0.10.1") to route fees to core development for a period of time (e.g. 2 years). This will benefit everyone. (well, it will probably slow mining hardware development by about 1/1000th - so arguably those guys will suffer).

I saw this on another thread...  That is a great way to spread the word about Bitcoin. Not only do more people learn that Bitcoin is an alternative to dollar, euro, yen, - but the message gets passed around, and around, and around while the old school currencies are diminished. Let's use old school currency (fiat) as our message carrier. Where can I buy a stamper to stamp all my notes? If everyone also buys a stamper and stamp notes in their country - EVERYONE will know about Bitcoin in a hurry. Somebody please organize sales of stampers and tell us where to buy them!!! You could make a shit ton of Bitcoin if you started selling these next week. I'd buy one today!!! |

Reminds me of the time I was addicted to Viagra.... It was the hardest 2 weeks of my life. *joke. At this stage, I think hookers might be clueless about Bitcoin and they would most probably only accept : https://en.bitcoin.it/wiki/Casascius_physical_bitcoinsIt might be interesting to speak to them, and find out what they know about Bitcoin. Any takers? You'd be surprised. They can receive bitcoin all night and easily cash it all in at the 'D' downtown (bitcoin ATM) for a fresh stack of Benjamin Franklins. Those girls got a system. |

with that kind of face, I am not manage to finish your video
Thanks for trying. But don't watch the video, sell you bitcoin before it all goes to zero. Now BTER is taking your fake money. When are you going to learn? |
|
|
|
ZERO! before the year is finished. I told you so. I warned you.
Archived for future entertainment purposes.  I will be the one laughing and using this record to show how STOOOPID y'all are. U gonna C |

bro with all due respect,you are one ugly motherfucker.
Do yourself a favor and never get on camera ever again.
Now there is an argument in favor of your failed bitcoin - calling me ugly. Besides the fact that I am handsome and you all know it, bitcoin is going to lose you even more money if you stay in that garbage. ZERO! before the year is finished. I told you so. I warned you. Don't be a RETARD! |

That youtube video .Lol.
Glad I could be of service to you. Now sell all your bitcoin and buy silver. Don't continue to be retarded. ALL you people who still have bitcoin are RETARDED!!!! If you are so right why even come here? You are right ...right??? lol You made a video in 2011 saying bitcoin would go to zero shortly after you made your video.... oh and more than 3 years later....you are still wrong.  Listen genius - bitcoin is retarded!!! It is in the shitter and you all lost a shit ton of money. Get out while you still can. Or, just remain STUPID!!!! |

If computers can calculate an address from its private key, then why can't they do the reverse and calculate a private key from an address?
Not all calculations are reversible. Suppose private keys and address work like this: private keys are long numbers, and addresses are the sum of all digits. Obviously a simplification, but just as an example. So if you have private key = 134505719542, then you can easily calculate the address: 1+3+4+5+0+5+7+1+9+5+4+2 = 46. Now I have another address: 43. What's the private key? Any number of which the digits' sum is 43? I don' think your example really explains why a btc private key (actually, as far as I know each address has something like 2^100 private keys), can't be calculated from the address. His example does explain a lot to be honest , I personally got it  Thanks for the information Kazimir , really helpful ~ Madness In his example, it is extremely easy to calculate not just one, but many and all the possible private keys of an address, with nearly the same difficulty of the reverse, it surely doesn't explain bitcoin at all. Stupid people should just be happy with the fact that we let them remain here with us on Earth and they get to benefit from all the smart people who make cool shit. BitNerd, Don't try to figure out math. You are annoying the numbers. |

It's a Poisson process, with a mean of 10 minutes. So... What is the probability that the next block will be found within 10 minutes from now?
63.212% .... Wouldn't a number closer to 50% make sense for the 10 minute mark? Some people study statistics, some study art. It's all good. |

a piss poor attempt at trolling this good forum So whenever someone posts something you don't agree with - they are a troll? My point is made. I don't get why you people call it trolling if a guy says something you don't like. Why don't you just move on to threads with shit in it you do like. |

The guy is an attention whore.
He gets his fix by talking nonsense sprinkled with controversial bits he found on Internet.
However, otherwise he is clueless about markets and currencies. Don't feed the troll.
you already fed him - too late. |

I've absolutely no idea what what are supposed to have told someone at what time, in what context, and for what reason or even why. Maybe you'd like to elaborate for us mere mortals.
Watch my video - dumbass. Why for the life of me would I want to do that? Nice try though. Then stay uninformed for the rest of your life - what do I care? |

Hi Guys,
I was expecting these machines could produce upto $50 dollars per day minimum for each machine.
Actually, there is only one 'Guy'. Your math isn't very good. Maybe you can go back to your university and get a refund from them. |
