One solution is to aquire bootstrap.dat via the Torrent network. That will help,

Use electrum or the Blockchain torrent
What with the necroposting? Borred? |

The biggest issue this brings up is adoption.. The Fraud and Theft protection that banks and credits company's provide is the main advantage they have over crypto and it is a big advantage. Every scam and theft hurt cryptocurrency adoption. If we ever plan to make Bitcoin or any coin for that matter widely accept, protection o some type need to be considered. Simply saying "Well they should know better." is not an acceptable response to theft.
If cryptocurrencies are going to be a globally accepted currency, they need to be usable and trusted, by those who may not know anything about computers other then checking their email.
The "you should know better, but we ban everyone we can catch"-approach seems to work for steam. Last time I checked they did not have problems with "adoption". Well they also restore your items in some cases... so you might have a point anyway. |

maybe rise the amount to pay with account created via tor
...which would ... ... affect legimitate users more.

Attacker change the link in the quote which redirect to his malicious URL (here i put virustotal.com just for example, obviously virustotal is not malicious) I am asking if Bitcointalk admin can do something against that Like find a trick to automatically turn off link in quote I understand your suggestion, but I doubt it will be done. A quote is no different from a regular post. Even if this would work via the quote tag, someone using that technique could modify the quote tag to refer a different post easily (see above). All browsers (expect maybe mobile) offer a way to spot this. Hover over the linktext with the mouse and see where it leads. IMHO this is internet 101. Dont click a link where you have no idea where you end up. This includes shortened links, which is a perfect tool for someone to link to a fake page. The hardcore version would be to go to the URL you think the link leads by hand and copy pasta the rest of the link. E.g. if you get a stearncommunity/blabla link, you go to the page steamcommunity and copy the /blabla behind it. I hope you found the difference... |

Hello,
everything is in the title: can you block link masquerading which redirect to malicious files ?

How do you suggest the detection of malicious files? Every time in the past I reported a link to a virus the post was removed very promtly. What exactly is your suggestion for the staff to do? |

Can't I just install electrum on tails, and save it? So I don't have to get it everytime? I am not sure if I understood your last sentence.
Its possible to modify a live system before you burn it to a DVD, but its probably considered advanced. You also talked about multisig, I don't understand what it is. Could you explain it briefly?
Multi-sig as in multiple signatures. Usually there is a single private key that signs a transaction. This signature makes it valid and allows you to spend the funds. This is basically what happens every time you spend bitcoin. You unlock your private key, use it to sign a transaction and broadcast said transaction. The idea with multi-sig is that you need more than one private key to make a valid transaction. E.g. for escrow services a multi-sig system can be created where the seller (S) has a private key, the buyer (B) has a private key and the person doing the escrow (E) has a private key. The typical design would be that they all create a single address and every two of them can spend the funds "2 of 3 multi-sig". These addresses would start with 3 instead of 1 like this[2]. The 3 has nothing to do with the amount of keys used. The 3 indicates that its a pay to script address [3] instead of a "normal" pay to pubkey hash address. On the protocol level bitcoin is "just" signatures, scripts and transactions thus its possible to create an address which funds can be spend if the transaction spending them is signed by 2 of the 3 possible private keys. So in our escrow case, B sends the funds to the address, S sends the goods. If everything is how B expencted it to be B can sign a transaction and pass it to S to sign it as well and the coins are spend (usually to S). If something goes wrong B and/or S can contact E to decide where the funds should go. Neither B nor S can spend the funds alone, thus E can listen to all arguments and finally make a decision where the funds should be send to by signing the correcsponding transaction. E.g. OpenBazaar [1] will use this (mostly automated) as part of a mechanism to resolve dispute between B and S.

 Ist aber leider so, dass ich es habe. Muss ich etwa hier erläutern woher ich das Geld habe? Glaube wohl kaum. Nein. Natürlich meinte ich es in € auszuzahlen.
Mach nen Account bei ner Börse[1], verifiziert dich (z.B. via Meldebescheinigung), überweis die BTC dahin, tausch sie zum aktuellen Kurs und lass dir die €/$/etc. auf dein Konto auszahlen. Hey.
Ich habe nun 4.21493811 BTC gesammelt.
Deine Begriffswahl ist einfach komisch. Wir reden hier ja nicht von Briefmarken oder Kastanien. Gibt es eine Möglichkeit diese sicher auf ein Bankkonto überweisen zu lassen?
Sicher in bezug worauf? "Ein" beliebiges Konto geht in der Regel nicht. Soweit ich weiß geht nur das eigene. [1] bitcoin.de, kraken, bitstamp, etc. pp. |

I ask of this because I would like to create a simple raffle/lottery/etc script using PHP which anybody can use. For this I would like to know how can I determine:
Who just send 0.01 BTC to my adress?
How do I send back the winnings to the right address?
Ask for a return address. There is no "sender address" on the protocoll level [1]. I wan't this to be done without anybody having to register or create accounts.
I hope to get a system which can simply see: 95 people entered into the raffle, 95 recieving addresses and then return the full pot back to the winner.
What would you do if the transaction has inputs from 10 "addresses"? I know that this may no be a simple tast because btc can be spread on various adresses, so maybe this is not the way to go, but I want this to work without an API, which may shut down and recoding made nessecary
Any ideas?
Others have failed with this approach in the past, why repeat it? Let the user create an account, deposit to your site, do the gamlbing offchain and let them withdraw when they want. [1] https://bitcointalk.org/index.php?topic=897276.msg9877226#msg9877226 |

Thanks for the answer, I am just looking to get some practice coding so I can try and one day get a job as a programmer, everywhere I apply I don't get many call returns because everyone wants experience. Its hard to get experience if no one gives you the chance to get some, so I want to start working on side projects to show them I can code

I installed bitcoind 0.9.3 on a debian server and tried to download the blockchain, but it seems to be leaking a lot of memory.
while running bitcoind, ps says the process is using only about 700 Mb but the memory usage display on the sever keeps going up and up over time. After I stop bitcoind most of the memory is still reported as being used even though there are no other processes using nearly that much memory.
Are you sure about this or is this an issue of your understand of "free" in regards to the understanding of linux of "free"? see here: http://www.linuxatemyram.com/Also the rate that it is downloading blocks has slowed to something like 1 per second.
To increase sync speed use the torrent. Is it possible that this is caused by an error in my bitcoin.conf?
I doubt it. You can set e.g. dbcache to 4 in order to lower the impact on memory used (actually used). |

Look at his post history before today and you'll see a suspicious gap exactly a week long in which he wasn't posting. Just saying.  That user is back with ~43 one liners just today. Guess someone didnt get the message. Modlog is two weeks.
When I look at the modlog, one of the last entries I see is this Nuke user: N/A in topic #0 by member #402358This user registered on this forum on 12-Dec-14. Assuming he was nuked immediately afterwards, I am able to see entries for maximum 7 days. Are there additional pages which I am missing? Weird, it used to be 2 weeks. IIRC there is also a limit to the number of entries shown, not sure if theymos said that or I imagined it though. All I could find with a quick search was that the listed bans are apparently permabans. All bans listed on that page are permanent.

Does anybody see a flaw?
I haven't really tried it out, so there might be something in it.
Not really...  Lets make some assumptions and see where we end up. You do the steps given and we assume that I was able to take over your machine (the one you use in step 1) with a rootkit. Possible actions would be: #1 I manipulate the source from bitaddress.org while/directly after you download it (signatures/public keys are replaced ofc) #2 I manipulate tails #1 and #2 can result in the following: You actually have a private key I dont know, but I just replace the address with one (or several) of mine, thus the moment you send funds to "your private key", I own them. |

Thanks for clarification.
I think there are a lot of users affected which use their home server to host bitcoind behind a dynamic address and are probably not aware of this bug.
Found it [1] its almost 4 years old now and it was worse back then, but the core problem still exists. I dont know how difficult it would be to create an external command (e.g. bitcoind rescanownip) that is executing the code needed to detect the local IP. I'll use a cronjob for a daily restart as a work around.
That should work. Esp. if the disconnectes are at a fixed time. [1] https://github.com/bitcoin/bitcoin/issues/48 |

I see something like this for the first time, is it possible to set your own fee price?  Depending on the wallet you use, yes. |

Hi,
I have already posted this to reddit but sadly did not get any reply so I am trying it here now.
I am running a full node and it's working fine until the 24 hours adsl disconnect (NAT with port forwarding enabled). But I don't get any incoming connections after the disconnect. I think the problem is that my new external ip address is not dicovered:
Yes, its a known problem. It was discussed on github a while back and the core devs decided that not enough people have the problem to care about it IIRC. -snip-
Is there any way to tell bitcoind to check my external ip regulary? I did not find any setting in bitcoin.conf
Nope, unless you restart it. There is currently no way to reinitiate the initial "whats my IP?" code. |

This, but the size of the transaction (2876 bytes) would suggest that 0.0003 would be a proper fee to get it confirmed fast. It would also help if the biggest input [1] would be more mature (older) but its very young. It will confirm... eventually. [1] https://blockchain.info/tx-index/72225792/1 |
