NXT :: descendant of Bitcoin - Updated Information

[zorke]

Could someone help me out?

I tried to withdraw from DGEX and they emailed me with:

"As your IP and withdrawal address have changed, we need to verify the ownership of your DGEX account to mitigate hacking cases. Could you please send the NXT account token from one of the following addresses:"

What exactly do I need to do?  How do I "send the NXT account token"?

You go to a little key icon in your NXT wallet and press it.
Type into a website field dgex.com and press on generate token. Copy and paste that long string of characters and send it to them.
It is pretty much a prof that you are the real owner of that particular account.

Where do the numbers 1/3 and .1 come from.  I still dont understand the problem we are trying to solve here

https://forums.nxtcrypto.org/viewtopic.php?f=17&t=836

I read that earlier today.  did you read that?  it was arbitrary, no math behind it.

http://www.docdroid.net/9yub/forging.pdf.html

It Should be Observed That this probability does not out stretch to 0 (asm! 1) if the bad guy has at Least 1 = 3 of all active balances in the network in the case of U-algorithm (corresondingly, At Least 1 = 2 in the case of exp-algorithm). There should exist some  specific  methods  for  protecting network against Such an attack in the CASE WHEN there is risk that (active) relative balance of the bad guy Could Become larger than the above threshold

it may be a good idea to limit the forging power of accounts by some fixed  threshold,  e.g.,  if  an  account  has  more  than,  say,  300K  NXT,then it forges as if it had exactly 300K NXT. Of course, a rich guy can split his fortune between smaller accounts, but then all those accounts would forge roughly as one big account (without threshold) under Exp-algorithm.   One  can  one  use  the  computationally  easier  U-algorithm without having the drawbacks discussed in this section.

how to interpret the 1 = 3 and 1 = 2 parts?  Nevermind, from the paper, its 1/3 and 1/2.  The problem is theres no way to determine "all active balances".  I suggested limiting effectiveBalance a few weeks ago, but 300K seems excessively excessively harsh, and will also make a 1000tps network pretty much unfeasable, since it would require literally thousands of TF nodes that publish their IP and have DDoS protection, HA redundancy, etc

This is the question. if you can not know in real time the total efecctive balance  must to look for another
solution.,

would have to conciliate the following features in my humble opinion;

a) limit forging power to 0.1 (limit 1/3)  total active balance maximun per account.
b) chance forging for any account and funds must be about one day (share fee group)

if you have 1.000 VPS nodes (share free groups) and you limit forging power to 1.000.000 Nxt per account
then

1440 blocs per day means that 1.000.000 Nxt account forge every day
if you have more than 10.000.000 Nxt in this 1.000 VPS nodes then 1.000.000 Nxt per account is less or equal
than 0.1 * 10.000.000 Nxt


c) 1000 TPS

i do not how is the solution

Many thanks guys, I'm on it!

To wesleyh and/or Come-From-Beyond (most likely the latter)

just my .5 nxt but In my most humble opinion, charging a fee for placing a buy or sell order has the
strong potential to be a deal breaker for many many people who trade.

No other exchange charges a fee for placing an order that may or may not go through and it's common practice for people to use buy and sell orders strategically, such as whales and their psychological maneuver using the order book to intimidate or elicit a hoped for buy or sell reaction. Sure whales can afford the fee but for many this will be a matter of principle and they'll go elsewhere.

Even regular people might put in a somewhat ridiculous limit order, just in case there's a quick spike in price. When the gambit doesn't work and the price moves even further away, you cancel the order. People are going to be pissed getting charged a fee for that.

These kinds of behaviors are important to people who trade.

Also, Ripple (a main competitor) has no fee (or an infinitesimal one) for trading even when the order goes through.

Any way to either eliminate the fee for trades, make them very very tiny (similar to Ripple) or at the very least only
charge the fee when the order goes through?

I am really hoping that this is considered and that it's not another thing that's "impossible" with NXT infrastructure.

l8orre,

Thank you for responding.  That Android client is a gem and  yeuye000 released the source code to the community.

That Android client needs to be developed ASAP for Nxt to maximize it's potential.

I mean, right now.  All it really needs is GUI  re-skinned and re-colored and 1 spelling error fixed;
And the code reviewed / updated / security review.

I'm no coder yet.  But I do know my way around computers and networks.

I need a coder's interest to help with that Android client and I can help support the project and put together a proposal for Nxt Infrastructure Committee.

A functional good looking android client would be huge. How does this client actually work? Since we have no local signing yet, I wonder how the client works securely.

I think spam protection is the reason. Spam protection for Nxt is not solved yet, so the fees are in place.

No reason my HTML client couldn't be converted to android / iphone app down the road too. More options

Click that little key icon next to the lock in NRS...  then input whatever text you like as the website and generate a token.

Send the token to dgex and tell them what you typed in the website field...  they will decode it and see that you are in control of the account...  just make sure you do it from one of the accounts that was in their email.

Wait a sec.  The two account numbers in the email from DGEX aren't mine.  This is my first DGEX withdrawal and I've only ever deposited BTC there before.  What's going on?

Someone should take the lead in launching Parallel Blockchain (NXG)  CFB has offered his expertise and help in doing this and it will benefit development of several current projects; NxtCash, X-Chain Transactions, etc...  I don't have the technical know how, but would suggest ChuckOne, Chanc3r, Zahlen.

Seems like your account got hacked.
Fortunately, DGEX stopped them with their verification system.

You should say to them that those account are not yours, and change your password

This is why we need to go to .01 NXT, at that price it probably wont be much of an issue. Also, this is why I think overall forging revenues will go UP when we reduce the min tx fee. Elasticity of demand based on price

If i am not wrong, the fee is small and it is for anti-spam purpose. Blockchain is not like centralized database and it can not be very big. It is a trade off.

[NxtMinnow]

You can review the info here https://nextcoin.org/index.php/topic,797.0.html

I have had a rock solid experience (zero Force Closes) using this client.  You can select which node you want to use and watch any account.  I think at the end of the day, you are trusting the node you specify to connect to that is running Nxt NRS.  I do not know if SSL is used for the connection to the specified Nxt NRS node, but it should be if it isn't!  At the end of the day; if you are running a light client, you still have to trust someone in your network.  Obviously local signing is preferable to remove that need to trust someone in your network.

Can someone really pound on nodeminer? I was expecting some bugs, a server crash, something.
Maybe I offer some bounty for bugs, but it is so young, it shouldnt be hard to find bugs.
Free nodecoins if you can hack the "mining" algo

FYI:
I asked Ian a question about his site (CIYAM.org). here is Q and A:

Q: Your site (ciyam.org) has been contently crashed and users are not able to either log in or introduce themselves. It seems that the traffic suddenly become too big to handle by the site.


A: There is a bug that I will fix tomorrow that has caused the problem - it is nothing to do with traffic.

The problem is having a user name with spaces (I thought I'd already fixed it but it seems I missed a spot).

FORUMS.NXTCRYPTO.ORG users:

Adminius over there is btc24 here.  Seems to have just completely vanished, hit by a bus, something, whatever.  Last login on either site was end of January.  Not responding to any of my PMs on either site.  Im not sure as to how long his equipment is paid up for - what happens if 1 day its just shut off?  So do we wait for that day or do we try to do something now?

This extended absence coupled with the fact that we still have no email password recovery coupled with the fact that we still experience unknown reasons for logouts gives me reason to post here and ask the community what are the thoughts?  I will post this on the forums as a vote.

If we want to migrate elsewhere, does anyone have any forums hosting they know we can use?  I can change the DNS A record for forums.nxtcrypto.org to be whatever IP address whenever it needs to change.

Community vote.  Or maybe btc24 comes back.

I'm waiting for an official sanctioned way by CFB on how to do local signing of transactions.

BCNext was delaying local signing to force ppl to install full nodes. I think we shouldn't wait longer and am going to implement prepareTransaction right after we launch Asset Exchange.

CfB, whats up with that?
