Nxt Helpdesk / Re: Is it safe to buy Ardr on Poloniex now?
« on: January 31, 2018, 10:08:11 pm »
Hi,

Is there an update on this? Ardor and ignis deposits are "temporarily disabled" on poloniex and hitbtc and I am wondering if you have information about what the problem is and when this might be fixed.

Thanks,
David

Nxt General Discussion / Re: Help me understand my ARDR asset
« on: January 27, 2018, 09:33:39 pm »
Hi,

I see my IGNIS now. I was looking in the "coin exchange" section of the client, but I now see that there is the coin selection drop down menu in the upper left of the client and their I see that I have my IGNIS coins and a bit of BITSWIFT coin.

The one remaining mystery regarding the amount and types of coins I have is that there appears to be a small amount of NXT associated with the NXT account linked to my "ARDR asset" in the asset exchange part of the NXT client. Are those NXT mine and how would I claim them as they appear to be associated with a NXT account for which I do not believe that I have the password? My impression is that no, these NXT are not mine, but I want to confirm.

Also, am I understanding correctly that the "ARDR asset" on my NXT account can no longer be sold because it has been fully converted into ARDR coing?

Thanks,
David

Hi,

Thanks for the advice blackyblack1. I opened the latest ardor wallet and checked my balances. My ardor balance appears to be the same as my NXT balance as my NXT asset report indicates. However, I don't seem to have an IGNIS balance. Am I supposed to? I have seen online that they talk of an IGNIS airdrop and that during that I was supposed to get 0.5 IGNIS for every NXT coin I own, but I don't see those either on the NXT or the ARDR clients. Am I doing something wrong?

Regarding cashing in "small amounts of ARDOR", what is small for you?

Thanks,
David

Nxt General Discussion / Help me understand my ARDR asset
« on: January 27, 2018, 04:37:42 pm »
Hi,

After taking a long break from NXT, I recently decided to look into how much my NXT account was worth and was pleasantly surprised to find that it was a lot more than last time I looked. So I installed the most recent client and took a look at my account and saw that not only do I have a certain amount of NXT, but I apparently have 1 asset, an ARDR asset that appears to be for an amount of ARDR coin equal to my number of NXT coins. Does this mean that when ardor was created I was automatically given those ARDR coins? If that is the case, then given how ARDR is trading, this would appear to be much more valuable than my NXT coins themselves, correct?

Can someone bring me up to date on how to "claim" those ARDR coins? For this ARDR asset, the NXT client lists an "Account" number that is not my standard NXT account number, but it still begins with "NXT-". Is this my ARDR account number? Is the password for this ARDR account the same as the NXT password? In the NXT client, when I click on the account listed next to my ARDR asset, it says that that NXT account has some other number of NXT associated with it. What are these and do I own these as well or in lieu of these ARDR? Sorry for all the confusion, but I really have taken a long break.

Regarding both my NXT and ARDR, if I want to cash out some of them for USD or Euros, can you give me advice on what are the easiest and most reputable ways to do that?

Thanks for the help!

Cheers,
David

General / Re: Raspberry Pi for Nxt

Hi,

I think I see why things are not working.  The user interface server is not starting on port 7875.  When I look at the output of run.sh, I have the following:

...
[2014-05-12 20:45:43.278] Started peer networking server at 0.0.0.0:7874
[2014-05-12 20:45:43.332] Started API server at 127.0.0.1:7876
[2014-05-12 20:45:43.383] Nxt server 1.1.1 started successfully.
...

There is no mention of the user interface server.  I didn't knowingly do anything to cause this.  Just to make sure I didn't unknowingly cause this, I have deleted my old NXT install and unzipped a clean one, which is now in the (long) process of loading up.  In the meantime, does anyone have an idea what is going on?

Thanks,
David

I recently updated to 1.0.0.  When trying to open an account from the Midori browser, I just got some strange blank screen with weird blotches of color.  Has anyone else experienced this?  Is midori not powerful enough for the NRS client?

Thanks,

Hi,

Feel free to show your support on my bounty request:

https://nxtforum.org/technical-development-applications/bounty-request-for-blockchain-analysis-tool

Note that my toolbox has not been specifically updated to work with nxt 1.0 because I haven't had the time.  In particular, account balances don't know about NQT and may have problems.

Cheers,
David

Hi,

The type of graphs I had in mind can be seen in a report I did on NXT activity dating from last month:

https://github.com/dmkaplan2000/nxt_state/blob/master/nxt_state.md

The visual aspect of the graphs themselves can be improved, it is more the content that I think is interesting and would like to find a home for.  I would like to add to this some more analyses of alias system use and eventually asset exchange activity, along with individual NXT account NXT and asset balance time series.  As this will be based on an R toolbox, almost any analysis one can imagine could be added.

Cheers,
David

As I understand it, nxt.org will be a site more geared to the beginner user.

In the background I am developing nxtcommunity.org as a site where more seasoned or bold users

In that case, what is the intended evolution of "nxtcrypto.org" (which I have always regarded as the "official" site) and "nextcoin.org" (which I have always considered a private DGEX venture)?  What about nxtra.org?

Considering your planned evolution, it would seem that my type of analysis graphs would be more useful to a seasoned nxt user or seasoned investor.  In any case, I don't really care where my graphs end up, I just want to get them out to as many users as possible.
I would also want a site that is stable in terms of leadership and unlikely to disappear...

Cheers,
David

Could be, but I wouldn't mind understanding better how nxt.org (which currently redirects to nxtcommunity.org) fits into the growing web of NXT sites.  It is hard to tell what is "official", what is a one off, what has real backing, etc.

13
Yes and no.  longzai1988 has a fairly simple set of charts available compared to what is in my nxt status report.  His website is simple and modern, so maybe there could be some collaboration on visual presentation, but I don't think C++ (I believe he used that) is the ideal tool to do statistical analysis of the nxt blockchain.  Having a well-documented R toolbox gives everyone access to a huge array of statistical tools for analyzing NXT activity (R has over 5000 add-on statistical packages, including a package for working with the bitcoin blockchain).  R is widely used by scientists, statisticians and economists, i.e. people we would like to have interested in NXT.  i8orre also has a tool for doing some analysis written in python/scipy, but the community using scipy is much smaller than that using R, particularly among economists and business sectors (scipy tends to be more computer science and engineering) and it has far fewer add-on packages for doing statistical analyses.

Cheers,
David

Good question.  I would propose something like:

1) 50,000 NXT for existing R package
2) 70,000 NXT for implementing regularly updated NXT status charts to be integrated into a standard NXT website (e.g., the blockchain explorer).  This would require collaboration from the person responsible for that website.  I am proposing to provide charts and scripts for regularly updating them, setup of R package and scripts on their server, etc., but not to build the website to display those charts.  I could make a basic website to do this, but this isn't really something I am particularly good at.
3) 100,000 NXT for adding asset exchange functionality to R package and implementing regularly updating charts for asset exchange.  These would be charts detailing activity by asset type, accounts most active by asset type, asset time series, etc.  Website for charts would need to be under a similar arrangement to (2).  This task would also include maintenance on (2) to adapt to NXT->NQT blockchain switch and addition of any new transaction types that may be developed along the line.
4) For long term maintenance of code, we would have to work out some sort of remuneration scheme (or perhaps a community of users of the R package will develop and this won't take much of my time).

Note that I altering somewhat my initial proposal which was asset exchange first and regularly updating NXT report second.  This is because asset exchange is still somewhat in flux with regards to functionality and is probably not going to be released to the general public for a little while still.

Cheers,
David

Nxt General Discussion / Re: Bitcoin's distribution history
« on: April 14, 2014, 11:56:38 am »
It would be interesting to get that data and calculate inequality indices on it and compare with results in my nxt report.  I honestly have no idea what the result would be as the chart itself is non-linear and hard to interpret in terms of standard inequality measures.  There are indeed a number of accounts with very large BTC balances, though as one of the people responding to that post points out, more and more people are using online wallets that group balances belonging to many people into a few accounts, artificially inflating the concentration of wealth. I would also note that wealth concentration is a bit more problematic in the NXT world as the stability of nxt forging requires wealth to be distributed among multiple individuals.

General / Re: "NXT network monitoring" funding request
« on: April 14, 2014, 11:41:15 am »
Only if the centralized "nxt monitoring" server does things that are so complicated that no one else can reproduce them. One of the reasons I decided to release my R package was that I felt there was more value to the NXT network in having open tools for verifying the activity of the nxt blockchain than there was to me personally in creating a proprietary "nxt stats" website.  With these types of bounties, we should definitely make open sourcing results a condition...

Cheers,
David

Great! I was asking if there was something like a "description" field where clients could put other additional information that we aren't going to specifically single out, suggesting that that additional information could be a JSON string that clients could interpret in standard ways.  I agree that the core NXT protocol shouldn't waste time trying to impose or choose a specific set of contact information, leave that to clients.  You might want to rename "description" to "other_information" to drive home that this can be an arbitrary string that clients could use for structured content.

Hi Jean-Luc,

Quote
Will alias assignment and alias transfer transactions always have the same behavior? Have the same minimum fee? The same policy of being purged or not during blockchain shrinkage? If not, are you going to handle each of those differences with another if/else based on ownerId in the code?

My answer to all these would be yes, these should all be the same.  For me, the interesting part of aliases is the possibility of distributed DNS, creating a web address lookup system that requires no central authority that can squash access to a website.  My proposal puts everything in place needed for that goal - alias creation, deletion, and transfer.  In that world vision, transfer is a relatively rare operation - it should only happen if someone wants to sell a website or something like that. The other things you mention, such as payment confirmation and comment fields, are really only of interest if one is trying to create a market for alias names.  In my opinion, that is a waste of time, partially because I doubt it will work (the whole namespace market ship sailed and sank in the late 90's) and partially because we risk just replacing ICANN with the 20 or so men in bathrobes, t-shirts or completely naked who currently own aliases for most every word in the english language.  My proposal doesn't really prohibit the emergence of such a market, it just doesn't use the NXT network to facilitate it, which I don't really think we have any obligation to put in place.

That being said, there is one thing that is worrying me in general about "asset" transfer in the NXT network.  What if someone creates an asset and then transfers ownership of it to you without your permission or desire (imagine a "childporn" asset)?  The current system would give you no way to refuse that asset, would place a financial hardship on you to get rid of it, and doing so could be considered acceptance of that asset.  This is a real concern in a distributed system where you don't know anyone and it will be very difficult (without certain modifications) to tell who bought something and who didn't.  In this context, I am thinking that all asset transfers must be binary, i.e., every transfer should be accompanied by a reciprocal payment or "acceptance" (payment with amount=0) transaction which would seal the deal.  This is another argument for my idea of "paired" transactions that I don't think is of negligible importance.

Cheers,
David

This is cool.  Does the transaction also include a field that could be used for arbitrary JSON contact card info?  Perhaps there is some standard JSON contact card format we could "encourage"?

Cheers,
David
