NXT :: descendant of Bitcoin - Updated Information

[joefox]

I don't know how I feel about Nxt being described as a metacoin, but since Ethereum is also on the list, it's not so bad.  I have noted that Andreas has mentioned Nxt a few times as "a layer on top of Bitcoin", though, which bugs me.

"Metacoin" in my mind is a coin that is designed to have other coins or assets ride on top of it.  Mastercoin is what I'd call a layer 2 metacoin bootstrapped on a level 1 coin.  Ethereum is a level 1 metacoin, Bitshares is a Level 1 metacoin, and NXT is a level 1 metacoin

Thanks for that clarification!  Makes total sense.  And since CfB is already working on a PoW crypto based on Nxt's PoS, I'd say the characterization is perfect.

is there a byte limit for an alias?

Can turning off the computer  crash the transaction.nxt or blocks.nxt files?

yesterday my account balance isn't correst, so i delete .nxt files, restart nrs.5.9, waiting half hour
everything is ok.
then turn off the computer.
later i turn on it ,can't connecting NRS
in command line,type java -jar start.jar,
the information show the blocks.nxt has error,
so i delete them again,of course ,after that ,everything is ok again.

My hunch is that whatever method you're using to shut down your computer is a little too harsh on the Java processes, and is terminating Nxt before it has a chance to close threads and complete file input/output.  I know the devs have put some work into cleaning that up in the last few versions, so I'd recommend making sure you stop the server (depending on your platform, it'll be some variation of hitting CTRL+C in your server's command window) before issuing your shutdown command.  Might be worth giving Java a few extra seconds to finish the shutdown, too, just in case.

I'm always stunned when I reach the end of this thread, and 9pm on the East Coast USA< all the European NXTrs are fast asleep (or drunk, or with someone more interesting that me..)

I can't believe theres not 20 pages to read..

is there a byte limit for an alias?

Alias - (0, 100]
URI - [0, 1000]

NRS

Code:

if(aliasValue.length() != 0 && aliasValue.length() <= 100) {
   alias = aliasValue.toLowerCase();

   for(i = 0; i < alias.length() && "0123456789abcdefghijklmnopqrstuvwxyz".indexOf(alias.charAt(i)) >= 0; ++i) {;}

   if(i != alias.length()) {
      responses.put("errorCode", Integer.valueOf(4));
      responses.put("errorDescription", "Incorrect \"alias\" (must contain only digits and latin letters)");
   } else {
      uri = uri.trim();
      if(uri.length() > 1000) {
         responses.put("errorCode", Integer.valueOf(4));
         responses.put("errorDescription", "Incorrect \"uri\" (length must be not longer than 1000 characters)");
      } else {
...
} else {
   responses.put("errorCode", Integer.valueOf(4));
   responses.put("errorDescription", "Incorrect \"alias\" (length must be in [1..100] range)");
}

Also how do i change my nickname on this forum? when I joined up I went for a more random name, but now with NXT I want to be more transparent and use my regular nick "jefdiesel"

thanks

Hey Aaron,
I'm putting on a debate about Metacoin layers on FRIDAY in miami, will anyone able to speak about NXT be able to attend?  Mastercoin, Ethereum and Bitshares will be there.  This will run on LTB as a full episode next week.

Let's Talk Bitcoin!

Oh how I wish I were in Miami.  Or anywhere even close.

I don't know how I feel about Nxt being described as a metacoin, but since Ethereum is also on the list, it's not so bad.  I have noted that Andreas has mentioned Nxt a few times as "a layer on top of Bitcoin", though, which bugs me.

I've been thinking about a few topics lately that Nxt proponents should address, because they're also hot topics in the Bitcoin world:  fungibility, transparency vs security, counteracting centralization, the "mining economy", numbers of transactions per block (and how they change over time) as a measure of value, maintaining strong consensus on the network, and "scarcity" (which I am beginning to think is simply a myth in the digital realm).  I think Nxt has some interesting solutions for these issues and think we should be documenting them in the whitepaper.  I swear I'll get to it one day.

I'm also wondering where we are with finding someone to take the 10BTC fund for a cryptanalysis on Curve25519 key generation and EC-KCDSA signing...?  I stumbled upon this guy, from Amsterdam, who proposed a Curve25519 cryptanalysis in 2009, and am wondering if any of our Netherlandic friends (Damelon??) might want to poke him: Cees de Laat

Interesting event there. Could Niffy present NXT and talk about technical stuffs ? I don't think any technically strong guy plan to be in Miami yet.

What's a pity.  could someone go ? It is a excellent chance to present NXT. Ferment ? wesleyh ? Cfb ? how much would be a Belarus-Miami flight ticket ?

How about Ola  

Nifty is a great network engineer, but not a developer. Guys, it would be worth putting some of that bounty toward flying one of our developers to the conference. Getting in front of the movers and shakers is one of the most important PR opportunities for Nxt.

See thats a great idea, but nxtcrypto.org/start is just more info. Idea would be to have the app be right there, and the faucet.

What does the QR scan? NM.. same address..

Nifty and QTBC are working on it.

when will we see an official wallet program?

[Sebastien256]

My other concern is what if someone has computers creating a database brute force of 20 digit account numbers and corresponding passphrases that open those account numbers, then they just constantly scan the blockchain for accounts that are sent NXT for the first time that haven't sent NXT out yet and if the number matches a number in their database they can go grab the coins immediately?

That sound like a serious issue to me. Any other toughts on this subjet by other members?

EDit: with 64bits per account, to store every accounnts number, it requires a dictionnary of about 2048 petabytes... neverminds!

Wow, cards look great, can I get one sent to me for souvenir?

That has been talked about multiple times. The short answer is: there is no issue and you need to understand math.

I can't find the link where it is talked about though.

You bet.. kick me an addy in PM.

I heard somebody said Next is going to be 30$ in 2 years, what do you guys think? for 1 year and 2 year?

[brooklynbtc]

Great minds think alike.

Like I said, I'm going to Inside BTC in NYC in April and would love to get a faucet fund set up for this by then.

It can be maintained by a third party, and maybe funded by the half million marketing fund run by Salsacz

Marketing Team could issue redemption codes, with a time code attached, so they start the week of the convention they are created for, even track the IPs and the issuer name. Even an expiration date if desired.

So in my case, I could get a numbered allotment, that would all be valid starting April 1/14, and would all track as being registered to my user name, and given out in NYC, and save the IPs and the block chain transactions so the marketing team could pull back data and see how many new users we can gain out of these conferences.

As well check back in a few weeks and see how many held, how many sold their free NXT and so on. Hugely interesting.

OK EDIT>> I'm interested in doing this whole project, Faucet, code issuing, and data tracking. I'm going to look into setting it up. Anyone interested in helping with building the backend?

thanks

Thanks for the reply, if you find the link let me know.

My other thought is that I think we could take steps to minimize the chance of user error when using NXT especially with broader adoption.  This could be as basic as having the client not allow you to use passphrases less than 20 characters.  I have already seen posts from people who lost NXT because they didn't realize that the passphrase was all that was needed to access the NXT from anywhere.

I think it would be good if we could make it more difficult for people to accidentally send NXT to a wrong address.  Right now if you make any typo you can easily lose NXT.  I would much prefer if the account numbers that people use to send NXT are such that only a small percentage of the numbers are potentially valid so if you make a typo it will just error out and know that it can't possibly be a valid NXT address even if it was never used (Bitcoin addresses work like this, if you make a typo you can't send).  I would much rather give someone a 25 digit account number to send me money, knowing that if they make a typo it almost certainly errors out than a 20 digit number where one wrong number and your money is gone

Any thoughts?
