Does anyone know what's the deal with the "0" account? http://localhost:7876/nxt?requestType=getAccount&account=0 { "errorCode": 4, "errorDescription": "Incorrect "account"" }However, there are transactions that send NXT's to it: http://localhost:7876/nxt?requestType=getTransaction&transaction=18385933678340826032 {

}
...and the blockchain explorer has an entry: http://87.230.14.1/nxt/nxt.cgi?action=3000&acc=0Perhaps an NRS bug? looks like some people are sending both NXT and AMs to acct 0. but there does appear to be a bug in that API gives error in trying to get public key for acct 0 http://localhost:7874/nxt?requestType=getAccountPublicKey&account=0 returns {"errorCode":4,"errorDescription":"Incorrect \"account\""} instead of either a key or {} if no key |

you have to specifically enable SSL. and when you do that, you MUST use SSL. also when you do that, I believe you MUST EITHER create your own self-signed cert or you must purchase a signed cert. I dont believe the NRS version comes with the old 2008 SSL cert it used to come with
look in wiki howto for guide on certs

So I've been having trouble setting up a node under Debian.
This is the error I get after 0.8.3 starts:
./run.sh: line 1: 3004 Killed java -Xmx1024M -cp nxt.jar:lib/*:conf nxt.Nxt
Help is appreciated.
did you use apt-get to install java? give us output from "uname -a" and "which java" and "java -version" |

...
-Implemented Curve25519 algorithm:
* NXT Solaris is now a bit like "Electrum for NXT" (a thin client that does not download the complete blockchain, connecting to untrusted NRS nodes)
...
Very cool I think this is what the community has been needing to really help adoption. But lets talk about this from a trust and sustainability perspective... I had initially thought that eventually, all the public VPSs that I and others have been running with donated funds would no longer be needed when the network got large enough with mass mass adoption. But with thin clients, there will *have* to be something stable for them to connect to. Assuming NXT really takes off like we want it too, are we prepared (and is the centralization really even appropriate) to continue running a core of public hallmarked VPSs for the purposes of servicing thin clients? IF that is the desire, then at some point this sort-of-centralized network of public VPSs we have now will need funds to renew (I believe the 12 I am paying for with bounty should be good till EoY, and the other 13 that I manage are up to the owners to continue payment) as well as possible additional fees for extra bandwidth and CPU/memory upgrades if they end up getting hit hard for utilization. Is there a better non-centralized model? Or am I too paranoid? Do we just continue the current course? |

It' a bug in the Nxt server : Example : {"balance":684600,"effectiveBalance":684600,"unconfirmedBalance":684300} Are you sure thats a bug? That tells me that the nrs instance returning that api has, just prior to that api request, processed a sedMoney request from that account for 3.00 nxt, and that transaction has just not yet been written to a block Yes , I'm sure  where can I go to read more on the bug? FWIW the scenario I described is 100% legitimate, so I must have missed the bug discussion on your particular scenario |

3. Before actually enabling Asset Exchange, I need to make the transition from storing transaction amounts and fees in Nxt to nano-Nxt (0.000000001 Nxt), or whatever fits in a Java long
Are you gonna use floating point? in Nxt to nano-Nxt (0.000000001 Nxt), or whatever fits in a Java long
Are you gonna use floating point? or whatever fits in a Java long
Are you gonna use floating point? Java long

I would like to have an audit on the DGEX exchange to prevent mtgox scenario!
Go ask on nextcoin how they solve malleability issue for btc, nxt, and any other crrency they plan on adding In fact, all people who are coordinating with exchanges needs to make the exchange they are dealing with awareo of to not just trytotrack transactionId for outgoing transactions. Orsuffer mtgox fate (that is, if malleability really is the issue that took them down, im still not 100 percent convinced they didnt just take the money |

speak of the devil. I just lost internet and all my ssh sessions got terminated along with all three of the gateways. I think there were a few pending transactions, so this is a good test to see if recreating the state from blockchain is working.
I am having some server issues, they keep saying "bind() failed: Address already in use", but all prior instances have been gone for a while...
Edit: OK, all three gateways are rescanning blockchain, just from the first possible timestamp
Could that have been why I was just seeing 'not enough funds' when trying to send DOGE back to my wallet? I'll try sending back/forth again after my confirmations complete.

Opticalc, would you be interested in running one of the three DAC gateways?
I can *probably* manage one.. may have to ask lots of questions though... |

Hey I have a question with transaction malleability. From the NXT Wiki: Transaction malleability is an issue with Nxt, as it is with all cryptocurrencies. Do not rely on a transaction ID alone to verify transactions! ... So if an exchange should not rely on just looking for a transactionID, what is the proper method? Do they have to attempt to track sendingAccountID, receivingAccountId, and amount? - there was the CfB's answer: It's a problem only for exchanges that rely solely on transaction id. It doesn't need to be fixed. An exchange is supposed to pay attention to timestamp and other parameters of a transaction.
what parameters ,except timestamp? Amount or ReferencedTransaction. Can someone describe to me a practical method to use referencedTransaction for the purposes of exchanges tracking things? Im going to add more into the exchanges page on Wiki and this will be helpful. But... Why not be pragmatic here and fix the malleability issue in the NXT protocol? Would be a nice feather in NXT's cap and would make things much easier for adoption for all the new systems we *want* to come to NXT in the *first* place. IMO this could be something that allows faster adoption. |

ON BEHALF OF CIYAM (China firewall-censorship issues):
a) using a good password create a SHA256 of it
b) publish a hash that is the hash from a hashed “x” times
c) lock your account then after that is confirmed send a tx from your account to another (won’t be able to actually transfer any funds even after confirmed)
d) send a tx that provides the “x-1” hash (i.e. if you hash that you get the hash that was sent in b)
result is that tx from c can now *occur* and also the locking hash has now been changed

The two top 50M accounts!! What is their deal? Why are they not sharing their wealth or participating in the progress of their investment. I mean if we consider that the account No. 3 and No. 4 are DGEX and BTER that means they have almost double amount of coins compared to account No. 5 which has about 29M. That is a huge difference. Honestly I would be really ashamed if I was them and I am sure these two 50M amounts are poke in the eye to any new investor that looks our distribution just like they are poking my eye.
Heck, to start at least get your accounts under 50M so they are in the 40s or divide this 50M into two accounts of 25M, it will definitely look better for newcomers.
I really don't understand this!!
guys, come on... these accounts belonging to exchanges are deposits that people in this very forums have sent to these exchanges, and the exchange is holding them for people just like you and me (assuming we are users of the exchange). They very well CANNOT just gank the funds and start giving them out to other people. now some of those very large accounts *are not* exchanges; just single people who are perfectly content to let others do all the heavy lifting. Some of them are people who are helping out, paying bounties, etc. nothing really we can do. |

I'm trying to simulate TF using Ian's program if we limit all accounts to a 1% forge balance. Using 100 accounts holding 1% of the currency over a ten year period, I'm getting a combined best streak of ~23. This is combining the first 50 accounts.

very cool. I cant do this type of stuff - too busy with other things. I have a question of this scenario though; is it adding even more risk by prohibiting full balances from forging? If we prohibit lots of NXT from forging, then does the possibility of someone obtaining 90% of forging power (though forcing to use multiple accounts to do so) actually increase? |
|
|
|
Just a reminder: BCNext don't want NXT to be a currency. Coins on top of Nxt should be. Does this change anything?
Does this change anything regarding instant confirmation discussion? No. I thought the whole point of using instant transactions was for using NXT as currency.  |

People this thread is giving me headhache and we are losing a ton of time reading thing and searching the subject that we are interesting, we need really to move to a forum with nice functionnality. Also, I lost my password to my user account at https://forums.nxtcrypto.org/ and it seem that there is no way to recover it. I have contact twice the official forum e-mail. I did not get any answer for since 11 feb. It look like the https://forums.nxtcrypto.org/ is dead. Any help? btc24@bitcointalk is adminius@forums.nxtcrypto, the admin of those forums. I dont think hes been online in a month. I have been trying to give him some bounty from neer.g but he seems to have completely disappeared. that being said, i know hes been asked by tons of people to allow password resets by email, but so far hasnt budged. that being said, if the community as a whole wants to get yet another forums site up and running and volunteer admined then I suppose that can be done. And if indeed btc24 has been hit by a bus then I guess eventually the forums will break or miss payment and get shut downl i could then change DNS to the new forums if necessary. or whatever the community as a whole agrees on I will change DNS |
