NXT :: descendant of Bitcoin - Updated Information

[coolfish]

nxt system should have a validation function to verify the account is available.

e.g:
acct: 209832084023840384023
MD5 & SHA Checksum: DfwSgeH

so the new account: DfwSgeH-209832084023840384023

Check the MD5 or SHA to verify the account available..

thanks for this example coolfish,
could you explain further please how this checksum approach can verify account available?

it just a simple example.

acct: 209832084023840384023
MD5 & SHA Checksum: DfwSgeH    // from MD5("accountid")

so the new account: DfwSgeH-209832084023840384023  // from  substr(MD5("accountid"),6)+ "- accountid"

//substr(MD5("209832084023840384023"),6)=="DfwSgeH"
if( substr(MD5("209832084023840384023"),6)==substr("DfwSgeH-209832084023840384023",6) ) it is available..
else unavailable.

Each new account is password and userid combination : password-userid

Please see my thread about that in the other forum: https://forums.nxtcrypto.org/viewtopic.php?f=17&t=524
We can do a lot better than merely detecting if the user made an error. With the method presented there, we can correct what the user typed. - That's 2nd gen. :p

thx, ricot,

ok, understood. usefull for users typing in account numbers but this doesn't answer my question.
this doesn't help to prevent sending funds to hiberNXT, or does it and if, could you please explain how?

as said, i am currently on this, therefore i would like to understand the whole procedure.
from what i see the main problem is to copy or even type a number to send funds to
which is not the intended number and therefore the funds are lost in hiberNXT.

is this what we are talking about?

Each generation new account is password and userid combination : password-userid
The client should contain publicly available decryption function

e.g:

Code:

<script type="text/javascript">
function creat_new(a) {
     return acc_md5(a);

}
function account_check(a) {
	if(acc_md5(a.substr(7))==a.substr(0, 6)){
                alert("right account");
		return true;
	}else{
		alert("error account");
		return false;
	}
}
function acc_md5(a) {
     var b;
     .....
     ....
     b= .... +"-"+a;

     return b;

}
function send(a) {
     account_check(a);
}
</script>


Original ID: e.g: 209832084023840384023  (Normal generation NXT account)
New id:<input type="text" value="" onclick='creat_new(this);'/> // eg:DfwSgeH-209832084023840384023


Check id:<input type="text" value="" onclick='account_check(this);'/> //acc_md5(209832084023840384023)=="DfwSgeH"

Send id:<input type="text" value="" onclick='send(this);'/>

NextCoin card payment

Good day to all participants. Thank you all for the development NextCoin

If you look forward NXT can compete with Visa.

When NXT is connected to the card, will not able to drive the key length for the transaction when buying in a store, it is troublesome.

I suggest in the future to include NXT, and think how you can improve the payment for goods in stores using NXT without a key, for example, use a pin code.

I don't see how someone buying a store item is in any way a problem for nxt or even BTC right now. Can someone please enlighten me?

Well, the chance that, by randomly typing that new kind of identifier, you get to a valid account is 1 in 2 million. So money sent to the wrong address because a cat walked over my keyboard should be dealt with.
The only other option to send it to an unknown account is if someone logs into an account, gets the identifier from there and then looses his password. (Or he mistyped his password on the first try). This you can only avoid by making sure that the password is correct. That's a pure UI thing in the client and shouldn't influence account numbers.
So if someone logs into an account, and gives you the new identifier, it's very very hard for you to send it to another account.

You ether have your account wide open and running all the time on a cellphone (a major security risk), or you stand there and type in a 50 character secure passcode (a major hassle).

[loopgate88]

Isn't a credit card an "account wide open and running all the time"? Wouldn't whoever is trying to use nxt before infrastructure be sophisticated enough to use a password manager to just copy&paste the password onto nxt? This person is still very much not the average joe.

the harder part is:

1) Getting merchants to accept Nxt

2) How to lock the rate of Nxt...protecting merchants & consumers from volatile price movements.


NOTE:  We have to remember that most of the world will punish merchants if they don;t act according to the rules of the central government & pay their taxes.


We have to remember 75% of the world don;t even use Visa....and Visa is FAR FAR ahead of Bitcoin.


My Thinking is Nxt is way above just payment.
  

EDIT: But one thing is sure.....there are more people with Cell phones than visa cards on the planet....and that number will EXPLODE in the coming years.

Yes and yes and yes, that guy is still not the average joe buying a candy bar.  The medallion scheme I mentioned above is a first cut at trying to figure out how to get the 99% of the people in the world can use NXT on cellphones.  If we limit ourselves only to people who use the NXT client in a desktop computer cut and paste environment, we haven't yet conquered the world.

I would be surprised if a majority of bitcoin users can effectively operate nxt in its current state.

If we limit ourselves to thinking about problems that are so easily addressed when the time is right that they are almost not problems, we are thinking about the wrong problems. Also, I use keepass on my phone on a regular basis to cut and paste passwords and have done so for years now.

Africa is actually leading the way here on cellphone micropayments and there is much to learn on current efforts - or perhaps strategic partnering.  Maybe just like the out of Africa migration theory, the path for NXT to conquer the world starts in Africa before trekking out to the rest of the planet...

my thinking is China & India....both have more people than the WHOLE OF AFRICA.

EDIT: Yet they both have high smartphone usage but low bank account penetration.....BOTH COUNTRIES STILL LARGELY DEAL IN CASH.

ACTUALLY Africa is also showing strong INNOVATION IN MICROPAYMENTS.....SO I AGREE STONGLY WITH RICKYJAMES ON THIS POINT.

It seems where bank account penetration is low & cellphone usages is high....NXT has A GOOD CHANCE.....I REPEAT MOST PEOPLE in INDIA, CHINA & AFRICA connect to the internet thru their phones.

THATS WHY LOCKING THEM INTO THE NXT ECOSYSTEM THRU SOME FREE SERVICE LIKE MESSAGING WILL ALLOW US TO SLOWLY OPEN THEIR MINDS TO THE BENEFIT OF USING NXT FOR OTHER THINGS.....payment, trading, remittances etc.

FOUND MY LOST PASSWORD!!!!

I had an account with 1M NXT in it that I had thought that I had lost forever.  The password that I had saved in NOTEPAD did not seem to unlock the account after I had created it (and coins had been sent to it).  Turns out that my cut-n-paste from NOTEPAD was adding two end of line characters to the middle of the password when I setup the account!

I have NOTEPAD -> FORMAT -> Work Wrap on.  It appears that sometime when copying from Notepad, COPY-N-PASTE is adding 2 E-O-L characters in the middle of the string where the next breaks in the display, even though the characters are not there in the notepad file.

For proof of what I am saying, I will post the account, Saved off Password and NXT Password in a few hours after my transfer (out of that account) ages a bit.


Note, this is not a problem with NXT.....It is a problem with using NOTEPAD to store passwords.

possible, but I never had problems with notepad.

Either that or a black market where the participants are willing to deal with extremely volatility of currency while trading. Let's face it, without SR, bitcoin would not have grown like it did. Your insight is dead on.

EDIT: sorry for the incorrect quoting
