Announcing the first online NXT Wallet

https://wallet.mynxt.info

Features:

- Easy to use
- Access your NXT from anywhere
- Responsive layout: works in PC/Mac, Tablets and Phones
- Send/Receive NXT
- See your balance in NXT, USD and BTC

Is it safe?

We made it as secure as possible, keeping in mind that as we all know nothing in the online world can be claimed to be 100% secure.

If you want the details: All accounts are 50 random generated characters long, we use AES256 to encrypt each account address twice (once using a site-wide key and once using your master password). We also only accept SSL connections and hash all passwords (salted).

There have been discussions on the main NXT Bitcointalk thread around possibly making it even safer by doing the encryption/decryption of the account on the client side (as opposed to the server side) and we are looking into this.

Launch Promo

To make things more exciting, as a launch promotion we are giving away NXT in the following way:

The first 100 people to create an account at https://wallet.mynxt.info and post their NXT account ID (from the mynxt.info wallet) here: https://bitcointalk.org/index.php?topic=477526.new#new will get 10 NXT.
In addition, ONE of these 100 people will get a grand prize of 1000 NXT. The winner of the grand prize will be determined by the last 2 digits of the NXT Block ID of height 75000 (you can check the latest blocks here: http://www.mynxt.info/blockexplorer/)

ATTENTION: The promo thread (https://bitcointalksearch.org/topic/ann-first-online-nxt-wallet-477526) has been locked in Bitcointalk, so we will have to continue in a new thread in nextcoin.org: https://nextcoin.org/index.php/topic,4137.0.html

Please post in the nextcoin thread to be receive the 10 NXT and be considered for the 1000 NXT prize.

@CFB and others, would it be good if assets listed on exchange were somehow grouped? To bring order to the chaos. Some generic groups such as "currency", "ipo", etc..

Will this help if u have 1000 assets in a group?

This whole coin was dead in the water. The new tech is laughable and nothing that cannot be wrapped into BTC directly or through a 3rd party app. These coins live and die on their communities, and starting with a large centralized developer with major investors backing it does not seem like a good way to start a strong community. Real cryptocoins benefit everybody with equal opportunity. Coins like this one benefit the developers most of all, by far. Forget this coin. It is the anti-crypto.

YOU are the anti-crypo...

Btw, goog luck trying to get transparent forging into BTC.

Is double precision floating point really so unreliable?

This is peoples *money* you are dealing with James so I think you should not be so cavalier and actually understand how things work (or pay someone else to do the job *properly*).

If you take such shortcuts then your code will just end up as "junk" down the track.

I am sure there is some equivalent C code around and the code I wrote there could be reduced (as a lot of functionality it has you wouldn't need).

Would you be so kind as to educate me on how using double precision is being cavalier? I have used floating point a lot, even for iterative computations. For a gateway, all user facing operations have a very short length, eg. one maybe two operations. How will errors in the 14th decimal place matter when 1 satoshi is 12 decimal place even for 1000 deposit.

I am all for super precision, so once I understand the actual problem I will do what it takes to make it precise.

Please help me understand the issue. I read https://bitcointalksearch.org/topic/stop-using-floating-point-13837 and nothing in here convinces me that doing a single subtract will change the value of any deposit or withdrawal, down to 1 satoshi.

Also, the gateway code will be run in controlled environments and I will specify compiler, options, etc.

Again, please provide a specific example of precision problem that a gateway doing deposits and withdrawals will run into. What if I used 128bit floating point?

James

Let me please chime in also - the link to Wiki is a good starter. Quoting from that:

As decimal fractions can often not be exactly represented in binary floating-point, such arithmetic is at its best when it is simply being used to measure real-world quantities over a wide range of scales (such as the orbital period of a moon around Saturn or the mass of a proton), and at its worst when it is expected to model the interactions of quantities expressed as decimal strings that are expected to be exact.[37][38] An example of the latter case is financial calculations. For this reason, financial software tends not to use a binary floating-point number representation.[39] The "decimal" data type of the C# and Python programming languages, and the IEEE 754-2008 decimal floating-point standard, are designed to avoid the problems of binary floating-point representations when applied to human-entered exact decimal values, and make the arithmetic always behave as expected when numbers are printed in decimal.

To paraphrase: binary floating point arithmetic is a huge can of ugly writhing worms that is to be avoided whenever possible when decimal precision is crucial! In physical simulations, this is not really the case, but in financial, it is!

Please try these simple lines in python, matlab, or any other binary floating point calculator, and DESPAIR:

a=0.8

b=0.7

a-b==0.1
Out[6]: False <------ LOOOOOOOOOOOOOOL! computer can't see this ?!?! Grin

because:

c=a-b

c
Out[4]: 0.10000000000000009

then, when people loose money because of this, the software causing this problem is F****D

Just start another thread.

Apparently giveaways are forbidden in the ALT section and I could get banned if I start another thread. I will have to start another one on nextcoin.org.

yes, i have proposed to add some more fields like category some weeks ago also (also an url field to link to additional asset descriptions) but the best solution is to add this on client side.
this way the user can tag/categorize the assets individually.

ps: like bond/currency/mining contract/loan/crowd funding etc.

I do understand. Also, I am writing an alpha version right now for DOGE. I am far more concerned about problems regarding multisig transactions than computational dust.
James

This is really weird. You ask people to check your code, and then you just go on and on not even try to understanding the problem

Also - why sell NXT on exchanges to bag holders. It's better to sell those NXT in exchange for services that help NXT. Bag holders = stagnant economy. Workers = active economy.

Looking at the top of the top NXT accounts, those with the biggest holdings. I see almost no movement of NXT and i'm thinking what are they're thinking.

What good is it if you have millions and millions if NXT in the end will be worth less than if you did something with those millions and bought something that would actually help NXT?

Isn't it better to start thinking in terms of maybe you should do something with that money because in the end 20M will be worth more than 50M because those 30M spent made a huge positive difference.

For those interested the output of the little program I posted just before is this:

Code:

a = 13.060000, b = 0.540000, c = 13.600000
c == 13.60
a + b > 13.60

Now all we how done here is to "add" two numbers together and then compare and *bam* we are in trouble.

There is lack of support for people that want to use and implement NXT, that way we miss opportunities.

Apparently implementing NXT is not that straight forward, look at cryptsy, mintpal, atomic-trader, etc… none of them succeed without any help to implement NXT.

We cannot expect mass adoption if above persist, and nobody steps forward to either make some kind of procedure or help people out.

Another remark is that I have the impression interest in NXT is decreasing in favor of new alt-coins/clones.

How can we reestablish interest in NXT?

When is the AE going to be fully functional?

Think this goes toghetter with client release, no sence to release AE when avarage Joe cant use it.

Community decides when to release AE, when it is tested enough.

the community shouldn't overreacting if devs are silent for a while or another clon appears.
atm there is only btc and ethereum to measure with. emunie is broken and i don't see any
other coin/platform atm able to deaccelerate nxt. ethereum needs the whole year to go online
so we have enough time to built the best tools infront of these competitor. it is true that we
have many loose ends now but we can link them quicker than others because they are already
there while others still in design phase.

and here is my very subjective prediction: nxt -> +3.71 USD latest until 15.08.2014 Grin

I hope so. Then I can pay my debt to the bank and will be free. Grin

Epic win.

Care to elaborate how you arrive the value +3.71 usd
