I don't know maybe Genesis block (the first block)  or a block when BTC still don't have price  How wrong you are... |

The only way to "predict" hashes is by bruteforce, trying all possible combinations till you reach your desired hash. To predict the 4 you described, may not be possible. I have no idea how SHA256 works, but if it uses the whole data and hashes it once to get the 4, then you will require the whole data in advance to get said 4.

Apart from orphans, it's propagation time, Satoshi chose 10 minutes to allow the whole network to receive the new block in sufficient time, whereas shorter block time limits this somewhat, so some nodes stay behind if their connection is slow.

I was wondering... What is the block with the lowest hash, or what are the, say, 10 blocks with the lowest hashes? Is there a list? Also, until which difficulty would these blocks be accepted in the blockchain?
https://bitcointalk.org/index.php?topic=29675.0I don't think anyone maintains a list. Ah awesome! That's pretty interesting! So currently we are at: So the block would be accepted at a difficulty 5896.74 times higher than today's difficulty! Awesome! Which is to say the block hash would've been valid for even decades to come, maybe just one decade, who knows. |

im sorry but after 4 months work your 'skeleton' UI looks weak.
i don't recommend anyone using it at all. i smell security weaknesses and potential for loss at every click.
if you are silly enough to sign up. do not use an email address you us for other exchanges and DEFINITELY not the passwords you usually use. many "coming soon" websites are made purely to gather login details in the hope to find one fool that also uses it on another exchange that is funded. or to atleast gather emails to spam you with scams.
Really? Speak for yourself, you don't even know the meaning of a capital letter. Don't expect people to take you seriously either. |

It's not really as interesting as you think. You would look at it for 5-10 seconds and move on.

Once they are in, they are in forever. As for under which circumstance they can be accepted if they were discovered now, they would need to satisfy the requirement of being lower or equal than the target.
Yeah, I know, sure, sorry for the confusion  What I mean is: How high could the higherst difficulty be at the time the block gets mined given its hash? If I mine a block and it satisfies the current difficulty (is under the respective threshold), it could very well satisfy a difficulty multiple times higher than the actual difficulty at that time  Depends on the hash. I remember 2 or 3 years ago, there was a hash that was 20 billion(i.e it had more zero bits than the requirement), when the difficulty was but just less than a million. However a hash that is just slightly above the current difficulty will not be able to satisfy the requirement if the network difficulty was higher than the hash's. Example: If the difficulty was 1, the hash's diff was 2, it would satisfy the diff requriement of 1, but it wouldn't if the network difficulty was higher than the hash's. Actually, it's a bit of a misunderstanding I suppose, we are looking for the lowest hash, so basically <= target. Difficulty is just a human readable representation. |

Sure, it's just a bunch of algos.

Jericho was a good series, but it got cancelled. They apparently managed to bring it back for a second season, but it got cancelled again. |

If that solar flare had hit America, the whole world would've fallen into chaos. America may not be the only country in the world, but it's still a huge factor.

I would like to save the bitaddress.org code on my android tablet and run it offline. The tablet is a Nexus 7 running android 4.4.3.
I have es file explorer and nexus media importer. The tablet is rooted. I also have the bitaddress.org code saved on a flash drive, and an otg cable to connect with. So I guess I have everything I need; I'm just looking for some hints (or even some explicit instructions) from somebody who did this, or knows how to.
Android is probably not the best way to generate offline wallets. There are quite a few malware out there for Android under the guise of legitimate apps. |

Given that a jet like a 747-400 can weigh over 600 TONS we fully loaded you're not going to have any kind of parachute deploy to stop that thing from falling. Barring the plane losing a wing like MH17 the glide a plane has would still provide more lift than any parachute.
You know that the U.S plans to send people to Mars by 2025, right? And they will all be in a spacecraft that when entering the atmosphere of mars will still hurl towards it at incredible speeds, at which point, they will use a parachute most likely to decrease the speed of their descent. So I am very sure it's possible to do it. |

Isn't there an asian or chinese section for this guy?
He may be able to communicate in his first language there to find what he wants
Actually you install SCRIPTS on servers not programs, so his semantical use of scripts to run a server is 100% correct, although is english is broken, servers do use scripts
Now you can all apologize to timmy
A server is almost no different than your regular desktop OS, so you most certainly do install programs on it. PHP/for instance/ may be a scripting language as explained in Wikipedia, but the resulting code ends up being software in it's own right. |

That pull is correct, non-cryptographically secure functions should never be used to generate pub/priv keypairs. Also, a Bitcoin address can be generated in pretty much ANY language, not just PHP. It would have been great, if u please shared the secured PHP code... Everything you need is in that pull request. Ok... so u mean, I just need to change the random number generator from mt_rand() to openssl_random_pseudo_bytes() ? Yes. Just copy the changed code in that pull. thanks, can u plz help me out here => https://bitcointalk.org/index.php?topic=709974.0 ? You're in deep with that, one wrong move with rawtx and you can make a fee that is huge or simply send the coins to some wrong address. |

All the people actually answering this question should be considering that they're wasting their time. A poll 'How does Bitcoin work?' with the possible answers 'easy' and 'no'... A classic!
What the? I didn't even notice the poll. Is this some sort of troll attempt? |

i saw this script on several sites working since over one year.that means if you make it stable,and it pays out,there is no scam.do you understand?
but the thread title is looking for this title,not for your crazy answers.open your own thread and answer such answers.but not on my thread
In the mean time I corrected a little your title! Who can tell me the name of the script from www.golden-cows.com site? I will pay you! Otherwise you sound like a 3rd world guy who just got a PC and wants to scam people! Not to mention I doubt he even has the qualification to run his own webserver to host said "script". Actually, why does he even call it a script? To me this can only mean one thing, script kiddie. |

By special parachutes do you mean for the plane itself or for the passengers inside?
Both would be nice. I mean, shoot, do you want to die with the plane crashing in the ocean(provided the parachutes on the plane itself didn't work or not much) or do you want to land in the ocean safely with a parachute. Of course there are other scenarios, staying too much in the water would result in irreversible damage to your skin, unless you get eaten by a shark prior to that or simply dying from hypothermia. As for pressure and altitude, I am not familiar with those to give other conditions where the parachute idea might fail. |

Timmy, I am asking you once more, you said you lost 1btc to a hacker, so why do you keep asking for a ponzi script?

Even if the plane was made of super durable material that would not break during a crash, the shock would be absorbed by the passengers inside, and they would still die.
But if there were some special parachutes designed to open if the plane was falling to reduce the shock(provided the parachutes themselves don't get damaged), it could help significantly.
