please dont use our bitcoin currency blockchain for it, you pollute it
Why not? There's nothing wrong with dust transactions. Not really, that's server hosted and centralized. |

Hello bitcointalk!
I've been studying the world of cryptocurrency for a couple years now and I plan on purchasing my first coins via coinbase or Bitstamp, but first I want to ask the community which wallet would be best in terms of security and ease of use? Obviously blockchain.info is the easiest to use as all I have to do enter my credentials and the my wallet is there, but I'm not sure that I want to rely on a website to store my money.
Blockchain.info's the best in terms of web wallets. However, if you use it make sure you print a paper backup of your private keys. I'd prefer using the Satoshi Client, Multibit or Electrum. On the other hand, the most secure way of holding coins is on a paper wallet. Come on over to the Ultimate Help Thread if you have any further questions, https://bitcointalk.org/index.php?topic=645750.0 |

Guys, i need your attention! i really need to sell this!
You should communicate in the thread or via PM here, not via Skype. Also, would you be willing to use Escrow? |

First of all, thanks for helping out the noobies.
Could you recommend me begginer guides for mining, mainly about buying hardware, at what point the investment is worth it, which hardware to buy, etc. I've been searching for guides, but every one I find seems quite outdated.
Many guides are outdated because Bitcoin mining is no longer profitable unless you have thousands to invest in buying hardware. However, our miners are important because they process our transactions. Check out AntMiners, they're pretty decent ASICs. Or, if you want to take the cheaper route, just buy some AMD cards (: |

If you want to match the first five letters, you'll find a match on average 1 out of every 38 billion addresses that you generate.
As you can see, it quickly gets very difficult (and time consuming) to find an address that matches many letters.
Generally, I understand the numbers, I trust the numbers. But, isn't this a waste of generating numbers? By that I mean what if everybody who gets involved in BTC started trying to generate a vanity address of more and more first X letters, won't that speed up the possible duplication of numbers in some future life time? Or would it not really matter because all but one of those numbers, the desired vanity address, ever be used? Trust the Numbers..... Bitcoin addresses consist of an alphanumerical string with a length of up to 34 characters, excluding the capital "O", the capital "I" and the lowercase "l", as well as the number "0". Since there are around 1.4*10^48 possible addresses, the chance that a duplicate is found can be calculated using the birthday problem as 1-exp(-(4*10^17)^2/(2*1.4*10^48)), or approximately 0.000000000005%, which means there's a one in 20000 billion of generating the same public/private key pair. All in all, you don't have to ever worry about a collision or "duplicate" |

Could someone help me with how I could make a "vanity address"? I heard you can have a computer generate it with the letters you want yourself the address to have. But don't really understand how that would be possible to do. And how you would get your private key?
Sorry I'm sort of new here.
Hey! No problem at all, that's what the thread's for. What operating system are you using? |

Only 10 nodes per million people? I would've thought it'd be more in the US...
I'm thinking most people don't use the original satoshi client Although lightweight clients look nicer, I'd prefer to run the satoshi client to support the network. Others should do the same  How does that support the network? If you're using lightweight clients like Multibit you're just backpacking off the people using the satoshi client. from the stand point that you're not storing a copy of the blockchain on your own personal computer? I agree, but are we really at risk of losing the blockchain? The miners are validating it... One of the reasons why lots of nodes are important is redundancy. “It makes [the bitcoin network] ‘seem’ bigger, more robust and more decentralised, because there are more people uniting to run it. So there’s a psychological benefit.” - Hearn |

Stay strong bro, I'll be praying for you. I can provide escrow if you need assistance in that avenue. PM me.

Where the hell do you live that it would cost $6000 for 3 months of housing? You can rent out a duplex down here for $750/month...

Bump you up.
What does the the block header look like before and after hashing?
As far as I understand, a block header is the block hash. So it would look like this after hashing: 00000000000008a3a41b85b8b29ad444def299fee21793cd8b9e567eab02cd81 And to get that, you need a few crucial pieces of data: The client version, The hash of the previous block, the hash based on all the transactions to be included in the block, the time, the difficulty, and a random 32-bit number. Hashing it doesn't change it; it tests whether the header meets the target and will be accepted by the network. So various bits could change for each attempt. You could update nonce, timestamp, the Merkle root, or any combination essentially. |

I could act as escrow for your IPO if you'd like.
The fee would be 1%

Sweet! Hopefully the petition means something to their team and they implement it. It's really not too hard to do so. |

Well I still haven't got the answer to my question: I'm using multibit and I want the Public Key (It's different than address) of my address, how do I get it? I don't want to know how a public key is calculated, I don't wanna read a dozen pages of math, I just want to know how to get it, period.
Unfortunately, I don't think there is an easy way to find a public key from MultiBit right now. Thanks Kuverty. |
