NXT :: descendant of Bitcoin - Updated Information

[gbeirn]

Are the block base targets extremely high or do I have a problem with all my VPSs?

[Passion_ltc]

how compact a full featured client (inluding distributed application/smart contract features) can be?

i tell you: 665kb / 406 kb zipped, yeah!. even if i would add a complete chart engine for AE, the size wouldn't pass 950kb for the executable.
(compared to other alt coins clients which are between 20-50 times larger by less functionality)
the client is sdi based, means only the center hup starts folded, subcategories unfold on demand. all others windows can be arranged as desired. this saves screen space.
atm i am re-composing the gui to adding a native screenshot function to the client, means every important form (like send/balance etc.) has an screen button, dumping
the whole dialog content into a clean rendered png image. here is a send funds png created by this function.

here is a 1:1 screenshot with offense coloring from the complete app-hub (including a small gui bug) ;-)

http://www.nxtexplorer.com/download/nxt-hub-screen.png

the user can change the colors later via textfile. atm i am using the dark color scheme, just prefer high contrast and good viewable fonts
when acting with funds. some screens can folded or doing this on demand. the client is not ready yet but i am working hard to finish the dev asap.
the distributed application/smart contract logic took me 5 days which was planed for AE but i am simply eager to show the first real running protoype
by nxt while others concepting. with release, a fully functional quoteboard DNA prototype will be included. 
during test, the remotly executed and sandboxed DNA sourcecode will be hosted on blockexplorer node but could be located everywhere. AM is used
for payment and access signaling. not every workflow is solved for DNA, this needs a little more brainstorming but i am confident nxt will run the first one.

Super! Thank you.

There's one guy at one address (4747512364439223888) with 50 million NXT, creating block after block... not really fair I guess, but neither is Bitcoin mining.

Would you really want him to?

Sometimes I hope he will join the light side of the Force...

I think you misspoke... you mean "dark side".

My response would be the same a Luke Skywalker's.

[nexern]

great news, when do you expect it to be finished and released?

maybe we should also add a countdown on our main page

uff, thx but please don't. i am still behind schedule and don't need much more pressure.
i am as fast as possible to deliver an easy client but this needs a little more time.

1. Write an OpenCL implementation of Curve25519.  

http://www.jcuda.org/

OpenCL not CUDA.

For Java you have:  http://code.google.com/p/aparapi/

Sigh... yes you can indeed mine Nxt.

CUDA would work too, but would be slower I think.

Good thing you can PoW mine darkNXT; it's not lost forever.

What is darkNXT?

[Eadeqa]

Funny thing. Lyaffe made a challenge with guessing a passphrase https://nextcoin.org/index.php/topic,3718.0.html

I decided to simplify rules, created an account with simple passphrase and sent 100 Nxt to that account. The passphrase was an answer to the question: "I'm a big fun of soap operas and have no idea about security.". Guess what. Someone stole 100 Nxt before I even managed to post the question

What the hell? How is that possible?

It is already known that there is a bot running that checks the balances of very simple passwords. If you send some NXT to accounts of passphrases "1" or smthg, it will be gone within 45 seconds!

This is really scary.  There is apparently a continuous, ongoing attack against NXT looking for weak passwords.  

There is urgent need for an official client that makes secure passwords for the users.

From http://www.nxtcrypto.org/:

[...]
This allows everyone on the Nxt network to have the same reward potential no matter the amount of Nxt you own.

At least, misleading.

why nxt client looks old ?...the skin is awful
plz change it ...

4747? He is waiting for Asset Exchange. At least he said so.

Yeah, that guys sucks, really hope he sells all his Nxt as he contributes nothing to the community.

Really, I think it looks awesome!  Great job nexern.

[NxtChg]

I think at some point it's best if a new address format gets integrated more than just at the client level.

Over CfB's dead body.

[opticalcarrier]

You say that it is scary, but that is exactely what is happening with BTC and the brainwallet apllication. Someone created huge rainbowtables and runs a bot that detects incoming tx and just sweaps all accounts. Everything that is shorter than 12-14 digits ist just sweapt within <0.5 seconds.

Ive just sent a message to Jean-Luc:

or the next release can you change "Your secret phrase is too short
and can be easily picked by a hacker!" to be "This passphrase is too short, and will most likely result in NXT being stolen! Do not use words, sentences, or any literary or common phrase or sentence.  A secure passphrase will be at least 35 characters long and consist of random numbers, letters, and special characters.  Or you can use a combination of 10 random words that make no sense when put together"

also, when the user attempts to unlock an account, when the popup that comes up with the text box for the user to enter the passphrase in, please also print "A simple passphrase will most likely result in NXT being stolen! Do not use any common phrase or a sentence that makes common sense, or that is common in spoken/literary world.  A secure passphrase will be at least 35 characters long and consist of random numbers, letters, and special characters.  Or you can use a combination of 10 random words that make no sense when put together"

FC never changes... *facepalm*

xyzzyx was asking for OpenCl,
I think what FC meant is that writing for Cuda != writing for OpenCl...

To avoid the situation were people choose weak password, there is a simple solution.
Do not let them choose. The client should generate an account itself.

It would be like the bitcoin private keys. Hidden from the user, unless he's looking for it.

But to do that,  then you need a wallet.   That's because the user will not be able to memorize the key.

Nxt doesn't have a wallet.  

A "wallet" is nothing more than a file with private key in it.  This can be done on client side.

I think the upcoming official client by "Nexern" uses the following system, and I really  like it.

Ask the user to make a password (does not have to be strong). Make a random string and combine them both, so it will look like this:

(1) The user  makes a password called say "mypassword".

(2) The client makes a random password that is say "fdhghfgfdk5756fhfgh44r677#"

The client saves that random password in wallet.dat

Now the user's full Nxt password would be "mypassword_fdhghfgfdk5756fhfgh44r677#"

That would be impossible to crack.

The "mypassword" part will exist in user's brain, and fdhghfgfdk5756fhfgh44r677# part is saved in wallet.dat

Make sure to remind the user to backup wallet.dat.

you can change this later by yourself.
i prefer a clean and minimalistic approach for tools. you won't find blinki, blinki icons here, just pure usage.
but you can change colors and effects for the widgets like 3d buttons if you need this.

Is that another Nxt flaw?  It forces users to keep all their coins in a single address.  If this single address is compromised,  the loss can be much higher than a lot of addresses.

Is the nexern wallet open source?  Where can I borrow it?

It does not forces anything. If the user doesn't want to forge, he can split it all he wants

[pocesar]

An account with 2 million NXT generated 28 NXT... the 50 million NXT guy generated almost 100k NXT lol

The concept is pretty flawed. Whoever gets the most coins makes most coins, how is that different from ASICs on Bitcoin? Someone care to explain?
