Every block contains a special transaction called a "generation" transaction, which is created by the miner and credits the miners address with coins produced out of "thin air". This is the only case where a transaction can credit an address without debiting another by the same amount, and there is a limit to how many coins the miner can give himself this way. That limit is the "block reward" (originally BTC50, currently BTC25, and decreasing by half every 4 years) plus the transaction fees of any other transactions the miner included in his block.
It is perfectly allowable for a block to contain absolutely no transactions other than the generation transaction (even if there are many other transactions waiting to be included), however the miner will not be able to collect any transaction fees in that case. The transaction fees give miners a financial incentive to include as many transactions as they can (assuming those transactions have transaction fees - miners have no incentive to include "free" transactions, which is why free transactions often take a very long time to be included in a block).

My aim is,
1. Use same address every time, a1
2. a1-primary-key can not be used to spend the funds from a1
3. I want to use new key every time to sign future trxns
Basically, a1 is just a dummy / constant address and fund from this address is controlled by another address..
Impossible by definition. As I explained earlier, an address specifies what key(s) can be used to spend coins sent to that address. By definition, if a key cannot be used to spend coins sent to a particular address, then that key is not (and never can be) related to the address in any way. If a particular key is one of the keys associated with an address, then it is (and always will be) able to spend coins sent to that address. That's how the key-address relationship works. It is also not possible for one address to "control" another (whatever that means). If you want to require that a different key be used for every transaction (and you still haven't explained why you want to do this), you must create a new address for every time you get paid, and tell your payers to only send coins to your newest address and not re-use your old addresses. (This is the recommended method of using Bitcoin, as it allows you to label each address with the reason you expect to be paid there, so you can more easily tell who is paying you for what.) |

I just want to use single address forever, and spend using different keys every time.
You can do this with a 1-of-n multisig address, though I can't imagine why you would want to. What exactly do you hope to achieve? I can specify next-key with the current transaction, every time.
This is how change works normally. Though obviously if you want to spend your change with a different key or set of keys, it has to be sent to a different address. If you send change to the original address, or more coins are subsequently sent to your original address, they can only be spent with the same key you used originally (or any one of the original keys, if it is a 1-of-n address). That's inherent to the very definition of an address: an address specifies which key or keys may be used to spend coins sent to that address. Different key(s) == different address. |

I'd like to lock a dollar bill in box 1, forbid unlocking and opening the box, and spend it by opening box 2...
What you're asking is equally impossible for the same reason. You can't spend coins from any address other than the one that received them, and you can't move coins from one address to another without spending them using the first address's private key. That's the core fundamental of how Bitcoin transactions work.

According to your theory, some little twerp became King by busting open some giant's skull with a rock and some string.
He wasn't just some little twerp, he was the only little twerp brave and/or foolish enough to try it. Apparently everyone else thought giants were impervious to head injury (presumably as an evolutionary response to constantly bumping their heads in doorways). |

Who is David?
He's the guy who caved Goliath's skull in with a heavy rock hurled with uncanny accuracy from his sling. Although primitive by today's standards, in skilled hands the sling was one of deadliest ranged weapons available at the time, as Goliath discovered the hard way. The moral of the story is, when you're a little guy, carry a big gun. |

The main "practical" benefits of Bitcoin (other than ideological or socio-economic factors that Joe Sixpack couldn't care less about) are:
* It has much lower fees than other electronic payment systems (currently BTC0.0001 (about 1 U.S. cent at present exchange rates) per transaction)
* Payments are settled much faster than other electronic payment systems (about 10 minutes on average)
* It is "push" based, eliminating the risk of chargeback fraud for merchants
* No personal information is needed make payments, eliminating the risk of identity theft for consumers
* It can be used in any country
* It doesn't close on weekends or holidays

lastly, if the order book is the god of what price a btc is, then why couldn't a big fish put up large walls on eather side? then you would have a set price for the coin and no fluctuation. I mean hypothetically. to much risk involved?
There's not just a risk, there's a guarantee that anyone who tries this will lose money. Say you don't want the price to fall below $100. Easy, you say. Just put up a bid wall at $100. Now whenever someone wants to sell bitcoins for less than that, they instead sell them to you for $100. But wait - that means you just bought bitcoins for $100 each, from someone who was perfectly willing to sell them to you for a lower price. Whoops, you just ripped yourself off. The same thing happens if you put up an ask wall to keep the price from going up: you end up selling your coins for less than what the buyers are willing to pay. As you continue to buy overpriced coins and sell underpriced coins, you'll very quickly run of money, your walls collapse, and now the price is free to return to it's natural level. All in all, a complete waste of time and money. |

Soon .txt files won't be safe to use.  They aren't safe to use if you're dumb enough to write a program in such a way that it treats every text file it reads as a list of commands to be executed. This exploit would never have happened if the author of the PHP code wasn't a complete idiot. You don't pass arbitrary text read from external files into a function that can execute that text as code. That's the number one thing that non-morons don't do. |

It all seemed legit - why say he didnt have what i wanted if he was a scammer? etc
Actually, that's a pretty standard trick: the scammer wants you to think his supply is very limited, and he might run out completely if you don't buy right away. It's a tactic meant to discourage you from "wasting time" looking for more reputable vendors or reading reviews etc. Of course, it's always possible this guy is legit, but I wouldn't get my hopes up if I were you. |

I have the impression that this a rather new development. I'm not sure of the scale of the threat, or how well anti-virus software is prepared to cope with it.
It's not a new development at all. Basically how it works is, the EXIF tags (which can contain any text the author of the image wants) of an image on the web server contain PHP code. Normally, this wouldn't be a problem, since the PHP server should never treat EXIF tags (or any other arbitrary text read from an external file) as code to be executed by the server. But the PHP code on the server contains a function which can indeed treat arbitrary text as code to be executed, and the EXIF tags were (stupidly) fed to this function despite it being well-known that such functions should never be allowed to operate on external data without safeguards for exactly this reason. This allows whoever created the image to execute whatever code they want on the web server and basically take full control over it. Anti-virus software won't help, since it's not a virus - it's just ordinary text in a location where ordinary text normally exists. The real threat comes from poorly-written PHP code treating this text as though it were code. Anti-virus software can't protect against stupidity. |

nobody figured i was joking ?
I suspected you might be, but I figured it was more likely that you weren't. It's hard to know for sure. |

- Based off of Litecoin.
Like we don't have enough of those already. - Snazzy new icon.
Nobody cares. - Wallet software with the ability to auto aquire coins from other wallets.
Wait, what? What do you mean "aquire" coins from other wallets? Are you admitting straight off the bat that this is a wallet-stealing trojan? - Coins mined in advance for projects.
Because nobody doesn't like premining, especially when it's for unspecified "projects". - Bounties for people that contribute tasks such as coding, promotion and web design etc.
Pass. the currency won't have any value unless miners can buy Asic devices for it etc.
Which they can't because it's based on Litecoin instead of Bitcoin. So basically, what you're saying is that BunnyCoin won't have any value, period. Thanks for the heads up. i got some butterfly's and jalapeno's coming, then it's serious face bunny time !
I get it. No sense mining your own currency, that's what the premine's for, right? This is the stupidest attempt at an altcoin I've ever seen. Well, one of the stupidest. Or at least, stupider than average. And that's saying a lot. |

It would be helpful if upon registration newbies saw immediately some guidlines as to how to become a member with full rights.
They already do. It would be more helpful, however, if newbies actually read the guidelines instead of just seeing them. You say you weren't paying attention; that's forgiveable, but try to understand that there's not a whole lot we can do for people who agree to conditions without paying attention to them. You've really got nobody to blame but yourself in that case. RESTRICTIONS FOR NEW MEMBERS
After registering, you will be unable to post in any section except "newbies" until you have spent some time on the forum and have published a few posts.
If you are registering to ask a question, please ask it in the newbies section. Do not wait to ask it just because you must post it in "newbies": the question is very likely to have already been asked. If you don't end up getting good responses, you can ask it again elsewhere after you are established, or you can move the entire topic.
If you are commenting on Bitcoin, use your newbie wait time to read more about Bitcoin. If you are criticizing Bitcoin, find similar criticism using the search tool to see which points have already been covered. A good use of your newbie wait time is reading Satoshi's old posts.
ОГРАНИЧЕНИЯ ДЛЯ НОВЫХ УЧАСТНИКОВ ФОРУМОВ

Neither. Epilepsy in no way impairs a person's intellectual capacity or development. It is simply a category of neurological disorders characterised by seizures. In most cases the brain functions of epilepsy sufferers are completely normal in all other respects.

The problem is one of clear communication - if a date is written as DD/MM or MM/DD then unless the day is > 12 it is ambiguous - if written in the form YYYY-MM-DD it is not.
That's not the problem at all. The problem is that formats other than YYYY-MM-DD cannot be automatically sorted chronologically. Read the sticky thread. The ability to sort topics chronologically by the date the article was published is the only reason topics in the Press board are expected to have a date at all. To that end, any format other than YYYY-MM-DD is as useless as no date whatsoever. Is it really so hard for people to understand that?  |
