Why would running a full node on amazons service be any problem if its legit? Unless I am missing something?
None of them are full nodes, they all run on some "bitcoinj" version.
-snip-
I've updated my graph once more, and it seems that the problem is gone (for now).
Thanks, I have a working script that automatically scans for these connections, adds the IP to a log file and bans them for a day now. |

|

-snip-
Is the list that you've provided from your own node?
Yes, the IPs came from my new node. The old one does not seem to have this problem. I think its because its at its limit of connections anyway. Any ideas on why anyone would do this? What could possibly be gained for these asshats? I don't get it.
seems like someone is trying to provoke people into banning amazon/cloud hosting services. in all honesty. i see it as a good thing. no one should be running a full node on amazon/cloud hosting anyways, so if it has taken a crap DDoS attempt to prompt people to block these, then ultimately its a good thing Maybe. I usually dont like to outright ban an entire ISP (or hoster) just because someone is misbehaving. Their stupid report form does not even have a section "(D)DoS" though and they specificially asked for reports on this on twitter, yet the attacks continue. It boils down to my priorities and dealing with a low impact attack is very low on a long list. If there are new connections tomorrow, I will increase the ban time, probably to a month and just ban the entire amazon IP range. I know there are legit full nodes running via amazon, but as you said maybe they shouldnt in the first place. |

#1 posts about the forum should be in meta
#2 yes, VIP is 50 BTC and donator is 10 BTC
#3 yes, the price was set when BTC was sold for lower fiat values
#4 no, the price will not change
#5 yes, the money is used (for a new forum)
#6 yes, these questions have been asked a myriad of times before
#7 off topic, just out of curiosity. What is your definition of idiot?

I just banned them via core.
I did the same. Banned about 40 of them. Haven't seen any more pop up yet. Wait 24 hours they will be back (unless you set a higher ban time for core). Todays list of IPs below. They seemed to have kept the connection established longer[1]. I am considering just banning all amazon IPs (already banning /16 subnets anyway) for a longer time. Mainly because I cant take care of this every day or think about a more smooth solution. Might not be needed if Lauda (or someone else) finds a good enough pattern for a fail2ban script. 52.51.204.60

Just testing out this tutorial  first time making a signed message as well. I want someone to verify my new wallet address, I quoted my old one as reference I can't sign from that address because I forgot my password as it was a random bunch of letters and numbers which I wrote down on paper and lost the paper :s This account is verified to be mine as someone checked it two weeks ago in another thread (I forget the name of the thread, it's a popular thread though, think it was the staking account thread). New Signed message below: -----BEGIN BITCOIN SIGNED MESSAGE-----

Hi, I have around 0.08 BTC in a GreenAddress.it wallet and i'm using it with their chrome extension. Yesterday I tried to transfer 0.07 BTC to another BTC address and to my surprise the transfer fee was 0.00504992, that is 7.2% of the sent value, and about 2.28 USD. Fee calculation was /kb.Is that a normal fee or am I doing something wrong? My account balance consists of about 30 smaller transactions. Greenaddress kindly replied to my same question, saying it is OK. Any second opinion about this? Thanks for your reply. Cryptme Soooo, how large was your TX? |

Its impossible.
Not impossible, just highly improbable  -snip- Do you worry about the air in your room spontainously moving into a corner leading to your suffocation? Its the same realm of "improbable". Calling it improbable will give people the wrong impression. I am quite new to bitcoin, still reading the guide, and being puzzled about this. For example, if somebody just create one million private keys and run one million wallet programs at the same time, he would much likely receive some output that paid to one or more private keys (addresses maybe) he generated, and thus steals others' money
Could this be a problem?
A private key is a 256 bit binary number. When written in hexadecimal this comes to a 64-digit hexadecimal number, which in decimal is approximately 1.158 x 10^77. Each private key will produce a unique public key and corresponding bitcoin address. So there are 2^256 possible combinations of private key, public keys and bitcoin addresses. No, due to the use of RIPEMD160 there are only 2 160 possible bitcoin addresses (of version 1). To get an idea of the numbers we are dealing with consider the following.
The world's fastest super computer is currently capable of performaing 33.6 quadrillion (33.6 x 10^15) calculations per second. Even if we assume that this makes it possible to check one private key per calculation (the actual number will be less since checking whether a particular private key agrees with a given bitcoin address will need much more than one calcultion), it would need 3.45 x 10^60 seconds or 1.1 x 10^53 years to try all possible private keys. So to try and steal bitcoins that are at a particular address by trying all possible addresses, though theoritically possible is computationally infeasible.

As I see on the Blockchain the funds from 1K7Pci1re92vQuTSXbirmvQsmYMpXHQWbQ were moved to 1DdRMtkX6e8g19HPYHTv2iaQRy2umwLcgj and 1Bs19mjGZnX9fFj2TQ78ApqFB6gfHKxfaM
If none of those addresses are yours, then you may have been hacked and the 7.02 BTC stolen from you. As I followed the transactions from 1DdRMtkX6e8g19HPYHTv2iaQRy2umwLcgj and 1Bs19mjGZnX9fFj2TQ78ApqFB6gfHKxfaM I saw the funds have been split and moved to many other addresses, none of them is 1LBa3bAVF5RSfnFnm3sX1Zm5R8WU1J8xnK present in the code you posted.
Check your code for vulneraibilities, you may be a victim of a hack.
Nah, look at this line "otheraccount": "1LBa3bAVF5RSfnFnm3sX1Zm5R8WU1J8xnK",
The address 1LB has change addresses accociated with it, thats all. @OP an "account" is not the same as an address. A blockchain explorer has no knowledge of your local accounts, so it cant display them properly. |

Ok, so how do I do this?
If you have python already installed you need to create a token file[1] with the passwords you want to try. Read the whole page, its the most important part. Lets assume you want to test the words "Cairo", "Beetlejuice" and "Hotel_california" in the front followed by any 4 number combination. In this case the file should look like this: + ^Cairo ^Beetlejuice ^Hotel_california
%4d
Once you did this you copy your wallet file into the folder with the script and the token file and excecute the script. [1] https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#the-token-file |

when I try to install Pyro it says Python 2.6 is required. (Wich I have downloaded). And it asks me to choose directory. But unable to.
It says python 2.6 was not found in the registry.
Pyro? If you are refering to "PyCrypto", you dont have to install it. |

Oh this was difficult.
Whats the problem? |

I don't think that duplicate wallet address is virtually possible.
Its impossible. I think everything is taken care by blockchain itself.
No, if anyone else should ever gain access to your private key(s). Your coins are gone. Its just so unlikely that this happens by chance (or brute force) that we can reasonably call it impossible. There are no defenses against that in the code though. However, you can use your email address instead of giving away your wallet id if you are holding account with coinbase. It will save your from your money being stolen.
Unless, its coinbase that is stealing your coins. If you do not hold the private key, you have no bitcoin. All you have is a promise from some company you probably know less about than the store around the corner you get your food from. |

Just wanted to give a quick thanks to everybody who tried to provide me with assistance in this thread: it's much appreciated guys.
Unfortunately at this point I would have to conclude that I've lost the money. I no longer have the private key for the transaction and I foolishly neglected to back up my wallet. Guess that's one for the lessons learned file!
Anyway, thanks once again fellas.
Dont give up yet. Bear with me for a moment please. What the "reset" button does is that it resets your options (like where is the wallet file). The only reasonable explanation I can think of that this would have the effect (all bitcoins "gone") you described is if you in the past had your blockchain data or the wallet file moved to a different location. The reset would have restored this to the default settings, while your wallet file would still be at the old location. Could this be the case? Do you have a different disk you store the blockchain (and thus the wallet file) on? Do you maybe have renamed the wallet.dat to a different name for some reason? |

It has now been over 5 days since I accidentally sent bitcoins with a too small fee from my old wallet to my new wallet, and it has not been received.
From: My bitcoin-qt.exe, version v0.8.3-beta. At 2016-05-10 11:06.
To: My new Electrum wallet version 2.6.4.
Transaktions-ID: 487823c8ab2d791828241409d004f56cecc8523e84cc87caeaddb0431aa4b5d8
Please advice me to how I can either cancel the send or to make it go through?
Thanks,
Fredrik

Did anyone try already? Are he paying really? I just want to ask to know if he pays, I would like to try to do a transaction on the testnet first.
A lot of people claimed they can do it, but when asked, they vanished.I hope you're not the one.Make the transaction on the testnet, and if they are what I want, I can put money on the escrow if that's what you want. If you want I can do the escrow (free ofc) for you if needed. Im not sure I could do it, I just know I dont have the time right now to try, 0.01 or 0.05 does not really change that. Sorry. |

are you sure?
It seems base58 would have a 1/58th chance for a '1' There are no bitcoin addresses starting with "1Z...", "1Y..." The formula for probability is more complicated No? Address: 1ZXt58NWzZaGxmdcYBccLJL2WNQrTqhuR
Privkey: 5JCQvCDYtQ9fKkkngyAMsS2przu41Gv5KfC4F7zC4XYbikJyXQX

I think I have a list of max 15 different variations it could be. But there is some combination of numbers at the end wich I do not remember..
But the wordpart of the password should be one of these variations.
Sounds like there is hope. You can either try it yourself with btcrecover[1] or hire someone to do it for you. 15 different combinations and 4 (assuming here) unknown numbers is only ~15k passwords to try. That should take a few seconds on a modern CPU. [1] https://github.com/gurnec/btcrecover |

Hello! Is there someone who can help me? I have forgotten my password and did not save the seed for my Electrum bitcoin wallet. I still have bitcoins in there.  Kind Regards. How much do you know about the password? |
