about the sendMoney API, there's a parameter "referencedTransaction",
the explanation in wiki is"REFTRANSACTION is an option reference to a previous Nxt transaction ID"
can I set it to the previous transaction-ID of the sender account?
Is it ok to left the parameter empty(since it is an option)?
U can leave it empty or set to any transaction id. Ur transaction won't be confirmed until the referenced transaction is. I see, so the referencedTransaction makes some dependence for the transaction, if the referencedTransaction failed, the sendMoney transaction will be canceled, right? it's a good feature! |

does anybody know about mcjavar? We were in the middle of a transaction, he sent me NXT, I sent BTC, he disappeared  I hope he is just offline, but timing is a bit distressing. I received 13K, so I sent the full 2BTC, expecting 20334 more NXT to arrive. His acct he sent it from is empty: 11433600460445633305 **** My BTC: 12UBzX8csUVpaPYya8aw7WWU8L3sQ6X6xo Please send the 2 BTC to this address and I will deliver the other 20334 from my main account, but I want to make sure that you receive the first 13k.. **** bitcoin transaction 5a173ed430eb61274a518d87b2ef8d128c8685aea39ed90e3d2feca6341f32db James P.S. I know I shouldn't have sent all 2BTC, but I had dealt with him before, never expected any funny business over 1.2 BTC We really need a safe place to trade NXT! Sorry James, but you went offline after I've sent you the Nxt so I thought we will continue tomorrow. I just woke up and will get to my PC in about 5 minutes, just takes a s...  good news to jl777 he will be happy when he wakeup |

NEWSThe last chance to claim unclaimed coins is over. We have ~13M coins left and they'll be spent for rewards, bounties and development. Now we are running a reward program. I ask the community to post here links (with short description and link to BTT profile) to projects/persons that helped to promote Nxt. Only projects launched before the 3rd of Jan can apply. There will be several categories, BCNext will choose 3 best participants from each category. I'll contact project owners via BTT personal message to get Nxt account ids for reward payments. The 1st place will receive 50'000, 2nd - 30'000 and 3rd - 20'000 NXT. Categories: - Exchanges - Faucets - Giveaways - Utilities (blockchain explorer or http://nxtra.org/nodes/, for example) - Videos - Articles - Bug reports - Tech support - Public nodes deployment - Clients Please, mark project/person names with bold blue font. We r supposed to complete the list within 24 hours starting from now. if it is still open

Other / Beginners & Help / Re: who can explain how signing/verifing message works?
|
on: January 04, 2014, 12:41:30 PM

The verfication is done with your public key. Basicly its a o = m^d (mod N) where o is the signature, m is the message and d is the private key Because RSA has some vulnerabilites, the message gets hashed first. To check the signature you calulate o^e = m (mod N) where e is the public key to the former used private key. If the hashes match the message wasnt changed durring transport. This works because ed = 1 (mod phi(N)) while e and N again are part of the public key and d is the private key If you want more details, read the rfc 3447, its explained for RSA, but the principle is still the same Link: http://tools.ietf.org/html/rfc3447#page-27Edit: phi(x) is eulers phi function ( http://en.wikipedia.org/wiki/Euler%27s_totient_function ) thank you very much! |

hello,
I am thinking about a way to secure my account for the time being. If I generate an account ID outside nxt client(just use sha256/curve25519 to generate account id, not logon to the client), and send my NXTs to this account, is it safer or more dangerous than the ordinary way?
In this case, even the nxt client don't know my privatekey/publickey, it should be safer. However, since the accountid is only 64 bits interger, the probability of collision is much higher than 256 bits publickey. I read from other threads that when a new passphrase is log on, the system will check the publickey to avoid the conincidence of collision. But in my case, I generate the account outside nxt client, there's no corresponding public key exist in the system, what if a person logon later with different passwd but the accountid happen to be the same as mine? does my balance all go to his account?

So what happened here? I see my NXT have been stolen as well. I only downloaded the client from this thread. Is there any plans to revert the blockchain? Honestly if there is no plans to somehow correct this, I am giving up on this. This is very disappointing.
Account: 8439060069775407509
I'm sorry to hear that. simillar things to me. check your browser history, maybe some clues could be found |

In summary,what I found from Chrome history: from download history, the malware link was: http://162.243.246.223/nxt-client-0.4.8.zipsha256: 948ce760c379f13f4ea9def6babaa36b0d706bf91098f1d64945fdde3eac5f06 the creation time and modification time of the zip file on my local disk was: creation time:2013.12.31，20:31:14
modified time:2013.12.31，20:35:16 in that time period, I only accessed two pages: 20:29 https://bitcointalk.org/index.php?topic=345619.11740
20:30 https://bitcointalk.org/index.php?topic=345619.0 from the download history, I probably downloaded the malware from the first page,that is: http://info.nxtcrypto.org/nxt-client-0.4.8.zip(I found the new version and checked it on the first page, and it's true, there's an update there, but I don't like the mega site, its slow from my home, so I downloaded the link from the first page) the thief might changed the link directly,
or he might changed IP address of info.nxtcrypto.org
current IP of info.nxtcrypto.org is 46.28.204.121,
which is different from 162.243.246.223the following are some clues about the accounts where my nxt goes: 2 of my accounts were stolen, one of them lost 18198 nxt, the nxt goes to an account which only has one transaction, the account is 9793828175536096502, the nxt is still in this account, I find nothing from this account. another account of mine, which had 93 nxt balance, was stolen to an account which have many transactions, I found sth from this account: 6164081464868000542, the first transaction to this account happened at 16 DEC, which refers to another acc:496131565008433801, in this account, there're 3 incoming transactions from acc:6635869272840226493, which I remember is the account of dgex, each withdraw at dgex are coming from this account(at least for me), so, if the thief is the owner of acc:6164081464868000542 and acc:496131565008433801, he probably has an id in dgex! |

About my another account that was stolen:
this account is my first account,and it has a weaker passphrase,
so I left it, and almost never use it.
the last time I logon with this account, if I remember it right, was 2013.12.30 09:05:27 GMT, when I assigned a few aliases. and at that time, the client I used should be 0.4.7e!!!
so, friends, be careful about your account!!!!
I recalled another thing about the client, my 360safeguard(a security software on my PC) reported several times that java(or start.bat which start the client, I don't remember exactly) was uploading private information when I had the client running! the client version might be earlier than 0.4.7e!!! so, WARNING again!!! |

When did you download the client? I shall look into it. I deleted former versions, it could be difficult since they all have the same name "nxt.zip" |

Im the DNS admin for all nxtcrypto.org sites. 46.28.204.121 has always been the address, since info got created; its never been 162.243.246.223. No one else has access to change the records.
Someone else admins the info website, the guy Intel from these forums here.
So did you ever download 0.4.8 from any other place than the info site? If that is the only place you downloaded from then there are only 2 explanations I can think of. Either I changed the IP in DNS temporarily to make people download a bogus client, or intel made a temporary redirect to a bogus client at 162.243.246.223. Which would have been dumb, it would have been much much simpler for him to just temporarily post a bogus client directly on his info site.
So step back, take a few deep breaths, go through your chrome history, and be detailed and tell us how you got the bogus client.
I'm sorry, I didn't know you r the admin of nxtcrypto.org DNS, but In my post, I didn't accuse the DNS admin either, I just talked about the possibilities, and now you elliminated one(I trust you from your eliear posts!). the thief might be an expert on computer/networks, he might have some skills we don't understand. the chrome history is ok, I didn't miss anything, but the thief might changed the history, that's also an possibility |
