Hey I have a question with transaction malleability.  From the NXT Wiki:
Quote
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.

Hey guys,

To those that have tried my web client http://nxtra.org/nxt-client ; A beta version is now available for download here:

http://nxtra.org/nxt-client/dev.zip

Unzip, move the dev folder to nxt/html/tools/dev

Then go to http://localhost:7876/dev

This is assuming you have 0.8.1e installed (it will not work correctly on older versions!) - do not try

I suggest you connect to TestNet first though; in the upper left corner you can switch between TestNet and localhost. Try everything out in TestNet first, when you are comfortable you can connect locally. There may still be errors in the code, it's a beta after all.

Not everything is done yet, and Internet Explorer is completely untested. I suggest you use either chrome/firefox or safari for now.

Also need to do some more interactive updating after submission of forms, etc.

if you want, you can send me a message there via the alias wesleynxt (just open the send message dialog and type wesleynxt in the account field). Messages are not yet encrypted.

Let me know what you think.

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

We could help Bitventurer develop Nxt.org

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.

On that note, it could be beneficial for the the blockchain admins to add an * by each account that is held by an exchange on the "Top Accounts" section of blockchain explorer.  That way a newcomer could see that those specific accounts are not held by an individual.

New version of my Nxt client online at http://nxtra.org/nxt-client/

I will provide a downloadable version over the weekend that can be tested via localhost as well.

Lots of new enhancements.

- Everything updates automatically now, including the asset exchange. When a new block ccomes in the AE is refreshed to see if there are new bid or ask orders.
- Assets can be grouped, just right click on the asset column, and choose add to group (see screenshot below).
- Inclusion of "tentative" messages all over. These are shown until the transaction is confirmed.
- Contacts added. You can send to contacts as well.
- User info, just click on a user ID and you get to see transactions / aliases and assets owned.
- More stuff that I forgot.

Below are some screenshots, if you like this, please consider donating to 8189784314684138350  - thank you!

automated multisig DOGE gateway alpha test release!

it is still incomplete, need to add a lot of error handling, but it does do deposits and withdraws, at least in simple cases.

It rounds down to the nearest .001. To deposit DOGE into your NXT AE, just send DOGE from your wallet to the address you get from get_dogeaddr program. After about 10 minutes it should arrive. To withdraw DOGE into your wallet, just use the AE transfer asset function and return it to 18232225178877143084. Right now, not checking for 10 confirmations, so it should arrive in a few minutes.

I just want to make sure basic functionality is there and test simultaneous requests from different accts. Also, support for fractions are pretty new, probably have some issues there.

Just a quick sanity test to get me a list of must fixes and I can do that and add error checking and consistency checking this weekend. Also need a lot of realtime monitoring so that you can see the progress of your (and other) transaction.

There is every chance that with more than a few people using this at once, things wont go quite right. Maybe even confuse the servers into deadlocking as they need to reach consensus exactly on every detail of the rawtransaction.

If you want to test, but cant compile the dogeaddr program, just post your DOGE address and NXT address and I will do it manually. Also, if you need some DOGE, just ask.

James

compile with: "gcc -o get_dogeaddr doge_addr.c -lcurl"
usage: ./get_dogeaddr <NXT addr> <NXT acct passkey> <coin withdraw addr> [gatewayid]

valid gatewayids are 0, 1, or 2 it defaults to 0 if you dont specify

New version of my Nxt client online at http://nxtra.org/nxt-client/



This is beautiful! Is it open source?

YES

Old version is available here: http://nxtra.org/nxt-client/dev.zip - I will upload the new version over the weekend. Once I'm satisfied with all of this it will be put on github and hopefully become a community effort to enhance this client.

The reason I chose to go with HTML/JS/CSS is because it's well known and relatively easy to get, so others can help with development as well.

New version of my Nxt client online at http://nxtra.org/nxt-client/

I will provide a downloadable version over the weekend that can be tested via localhost as well.

Lots of new enhancements.

- Everything updates automatically now, including the asset exchange. When a new block ccomes in the AE is refreshed to see if there are new bid or ask orders.
- Assets can be grouped, just right click on the asset column, and choose add to group (see screenshot below).
- Inclusion of "tentative" messages all over. These are shown until the transaction is confirmed.
- Contacts added. You can send to contacts as well.
- User info, just click on a user ID and you get to see transactions / aliases and assets owned.
- More stuff that I forgot.

Below are some screenshots, if you like this, please consider donating to 8189784314684138350  - thank you!
