It's like a faucet right? And how much Bitcoin can be earn by doing this? It isn't a faucet. It is actually a captcha solving service which uses people to solve captchas. They pay up to 0.04 BTC per 10000 correct captchas. |

Just see this, and it is a good service  However, this will means a newbie of 14 activity, neutral trust and normal post quality worth 0.0105 BTC! Maybe you can adjust the algorithm? Yeah, I noticed. I think it is going to have to be a logarithmic scale instead of linear. That will require some more time to figure out. For now, I have a disclaimer  |

In my personal opinion, GUIs are a pain for the programmer. You can't 'prefer' that the OP concludes it as a GUI, since it might mean extra work, especially if they weren't doing it for web, and they're doing it for free as a service to the community. GUIs require more time, effort, and maintenance. At least for non-web contexts, a command-line application is a completely reasonable way of doing things.
GUIs are a pain, but fortunately GWT is very helpful and this gui is incredibly simple. Here is a screenshot  The code is available on github now. You can browse the code at https://github.com/achow101/BitcointalkAccountPricer. Pull requests are welcomed as are donations to 16mT7jrpkjnJBD7a3TM2awyxHub58H6r6Z. I will update when I get a server setup for the website. For now, you can download GWT, compile the code yourself, and do your own price estimation. |

satoshi only has 50 BTC?  I thought he has 1 million of them. He has a lot, estimated to be a little more than 1 million. However, his Bitcoin is spread over several hundreds, maybe thousands, of addresses when he was mining Bitcoin in the early days. |

Really cool project, only problem I see with it is that account prices seem a little high, but that's an easy fix. A cool final presentation of this project would be to put it on a webpage as you planned, and then have it automated by a bot. You insert your UID, click a button and then it'll estimate your account's value.
Like hexafraction mentioned, your original idea could easily be programmed with Javascript as well. I'm not sure how easy or feasible it would be to implement a bot with Javascript though, you might want to look into another language - it seems like lots of the sig campaign bots here are coded with PHP.
The problem is that I don't know javascript or PHP very well. What I am actually using is GWT which will convert my java code into javascript. It seems to work decently well. |

How will this estimator work? I enter my UID on this webpage of yours and it reads all my posts and give me a value in bitcoin? Looking at the code you posted, every stat is manually entered. It can be done by a shared spreadsheet on google docs. Don't need an app for this.
You just enter the UID and my code will retrieve all of your stats. It will get your username, activity, post count, trust score, and calculate your potential activity from all of your posts under the "Show last posts" link in your profile. It can take a few minutes depending on the person since Bitcointalk limits me to 1 request per second. If you have hundreds of pages, then it can take a few minutes to request and process all of the data. The code isn't done. What I posted was the algorithm. |

Thanks for explaining about the transaction fees. If you don't mind can you give / estimate what a transaction fee would be for an object of any size that you think would be a good example. I would just like to get an idea of how much these fees would add up to. Thanks
The typical fee is 1000 satoshi per kilobyte. Sometimes it is 10000 satoshi per kb to guarantee a faster confirmation. Also, another thing that prevents data from being stored is the block size limit. The current limit of 1 Mb prevents too much spam from bloating the blockchain although there are concerns right now about not having enough space for large amounts of transactions. |

So what exactly happened to bc.i?
I think they are probably under attack, as it seems that they only have 36 nodes connected instead of their usual 2000-ish.

He isn't talking about blockchain.info, and what he says is true. If someone were to connect to every single node out there (very difficult to do BTW), Virtually impossible. Even if you managed get connected to, let's say, 6000 nodes. How do you know if there is still an unknown percentage of nodes that you're not connected to yet? I know. I have tried. It failed miserably, including crashed my computer. then that person would know which IP address a transaction originated from. Then that person would be able to know that that IP address most likely owns the inputs of the transaction. This involves a huge uncertainty. If some node broadcasts a transaction, it will be propagated throughout the network immediately. The theoretical "superconnected NSA node" would get the same tx from hundreds of different nodes within milliseconds. The information you can retrieve from that about the originating IP is slim to none. Theoretically, with a superconnected node, then yes it is possible, since even those milliseconds are enough time difference to make the determination of where that transaction originated from. Of course, doing this is highly infeasible and incredibly difficult to do, as well as possibly physically impossible due to latency in network connections. |

This should be moved to the off topic section. This could be done either by printing a ton of paper wallets (even better since you can throw at him empty wallets), or by using physical coins (not recommended, as this might hurt).
Making it rain with paper wallets doesn't look as cool as doing it with cash. Although doing it with these would look pretty cool. |

It is not necessary. If you are using that account as a replacement for your original account, then you should let people you have done business with that you have changed your account. Otherwise, it is not necessary to let everyone know that that account has been bought. You should however stake a Bitcoin address so that in a few months, if something happens, the account is recoverable.
If you are looking for a Sr. Member account, I can help you.
BTW, this belongs in the marketplace.

I'm talking about the first point. He is saying the first node which process (relays the transaction). It is hard to find out which is the IP it originated from without directly connection to the client itself. Correct me if I'm wrong.
That is true. I think both of you are saying the same thing. Basically, if you were to connect to every single node in the world, then you would be able to know which IP address sent what transaction. It would simply be the node that first relays the transaction is the node that owns the private keys of the transactions inputs. As I said earlier, there are ways around this through tor, i2p and vpns. |

So how is the NSA going to detect how much bitcoins Joe has, or what he is receiving or spending? How are they going to monitor "his" Bitcoin traffic, considering that the P2P traffic he sends and receives is effectively the whole current Bitcoin P2P state, with anyone and everyone's data mixed together.
I read somewhere that when a transaction is broadcasted to the network then the first node to process that transaction is very likely the sender himself. Also read that peers can see your IP when the transaction is sent to the network but only from peers that you are connected to.If peers have ability to attach an IP to a transaction wouldn't for example NSA peers be able to log IP of every transactions that go through them, can peers chose which transaction they want to broadcast or is this random? When i use my client it usually says i am connected to a certain numbers of peers, what does these peers know about me? Sorry if my questions seems confusing, i am not very tech sawy but if you could explain how it all works i'd appreciate. Then you have read from the wrong source. The IP displayed on site like blockchain.info is merely the first node which relayed it. It is very inaccurate as people can connect to different nodes at different locations. He isn't talking about blockchain.info, and what he says is true. If someone were to connect to every single node out there (very difficult to do BTW), then that person would know which IP address a transaction originated from. Then that person would be able to know that that IP address most likely owns the inputs of the transaction. However, there are ways around this by using Tor, i2p, or VPNs. |

If you convert your private key so that your public key is compressed, you will get another bitcoin address. Since the elliptic curve can return 2 points for public keys, the compressed key uses one point, and the uncompressed uses another. This means that there are two public keys for one private key. By changing your key to compressed, you will be using a different address and cannot send Bitcoin from the first which had an uncompressed key.

Yeah USA going to win this one again...
One language for all, one currency for all. The alternative was "Euro" against "USD" but Europeans f**ked it up with Greece crisis. (and spain will be following probably)
And China? China is in another world dude. No one would want to go there. So basically China is worthless to most people.
Also, China is not worthless, the whole world relies on it for manufacturing their products and provide the cheapest human resources. Would you live in China? Would you live in Saudi Arabia? I know there are lots of european/american people live there, but would you? Most will say no. You don't like their culture, you don't like their language, you like nothing about them. So what makes them precious to you? Yeah i'd like them to keep making my electronic devices or send me oil from a faaaaar away land. On the other hand, I can live in USA or any other European land and i can adapt easily to any of those cultures. Because almost all people there know to talk in "English" That is the meaning of "worth" to me. Not every European country speaks English. Even in Western Europe, people will still speak their country's native language. In other countries in Europe, they don't all speak English. Most people in Europe will know English to some degree, but not all. Same with China. China actually teaches their kids English in schools (at least in the good ones) and most people their will understand English to some degree. |

Anyway, OP: How goes implementation? Do you need any assistance with the javascript or other non-java bits?
The code is finished, although a little messy. I will post it up on github within a day or 2. Perhaps you can help me with setting up the server so that the applet isn't a part of the webpage. Can someone explain me what the heck is that "potential activity" or "extra potential activity", please? I wasn't aware of such thing until now. (Today I've learned something new again ) Potential activity is how much activity that an account could possibly have at any given time. you can get 14 activity for every two week period. For example, if someone makes 1 post every two weeks, for 10 weeks, they will have 5 posts, 5 activity, and 70 potential activity. If they made 65 more posts at the end of the tenth week, then their activity can go up to 70. Extra potential activity is something I thought of which is just the amount of potential activity they have beyond their current activity. They can have 0 meaning that their activity matches the potential activity. Or in the example above, that user has 65 extra potential activity. I like the idea but I doubt that this will work. In the end everybody can quote a price he is willing to sell his account for. And when someone agrees to pay that price it's ok. That's how a free market works.
That is true, but I will try to make my estimator match the market. If my estimator follows the median, then this could let people know whether they are being ripped off or getting a very good deal on an account. It can also help people new to account selling by giving them a price to work off of. |

Question for OP, how many nodes should they run?
If not exactly proportional to how much BTC they mine every day, something near that number? I can't understand how you can think there are hidden nodes. This website should represent accessible nodes, right? If you can't see a node here, neither another node can see it, right? Or wrong? I'm no expert, I confess. That is not true. getaddr.bitnodes.io does not see all the nodes in the network, it can only see the ones that allow incoming connections and allow its connection. If someone decides to drop the connection to the site's node, it can still maintain connections to other nodes in the network. If those nodes connect over Tor, then they won't accept incoming connections and the only way that getaddr.bitnodes.io could know about them is if they connected to their node (which may not be possible). |

hello sorry for intrusion but my laptop shutdown unexpectedly whilst my bitcoin core was still in synchronisation and i was 2years 13 weeks gone.Problem is anytime i try running the app it shows me "error loading block database,do you want to rebuild the block database".
How do i proceed as i have already received coins which i have in two separate addresses and can not afford to lose this coins.
thanks..
Let it rebuild. Click Yes. It is ok, your coins aren't going anywhere. You need to understand that the transactions are public and can be spent as long as you have the private key, which is kept in your wallet. Rebuilding the databases won't affect your Bitcoin but it will take a long time. |

The code will be written in Java because I know Java the best. It will be open source and published on Github, but not yet as it is not completely finished. There will also be a website that has the java applet on the webpage for anyone to calculate the price of any Bitcointalk Account.
I wouldn't use an applet for trust reasons. I wouldn't trust a random unsigned applet, even from a potentially trustworthy user. You should see if you can get PHP, a servlet container, or JSP on your website to run it on the website's side. Alternatively, use Javascript which is a bit easier to trust on a webpage (I can try to help with that) I will look into those. Thanks for the info. |
