Funny thing. Lyaffe made a challenge with guessing a passphrase https://nextcoin.org/index.php/topic,3718.0.html

I decided to simplify rules, created an account with simple passphrase and sent 100 Nxt to that account. The passphrase was an answer to the question: "I'm a big fun of soap operas and have no idea about security.". Guess what. Someone stole 100 Nxt before I even managed to post the question Smiley
yes, in fact there would/could be quizes on the internet and then especially at the conventions/conferences, but answer will have to always have some additional phrase

another question lol

if i close my client.. i have to wait 1440 blocks before i can forge again right? it was finally forging and had to close it to upgrade to 0.5.11... :/

No, if your Nxt has been confirmed 1440 times, that's good.
Once you open the new client, you will start forging immediately again Smiley

Nxt NEM

Sure. It's up to you to decide. You don't like Dgex, then don't use it.

You can be sure that I will never use DGEX again.Grav seems nice guy, but DGEX is not prefessional.Thats all.

it's just businness.

Absolutely. Just business. As for me, I bought nxt at 0.000069 on Dgex yesterday. About 5% lower then on Bter.

I'd love to use Btc-e only. I think it's a perfect exchange, but they don't trade Nxt, so I have to use Dgex and Bter.


not just business Smiley
Shouldn't we support "NXT ecosystem" and have some tolerance for development and error corrections.

Ofc it is so that problems must be brought into light, even smaller ones, but then should have patience ...

I have a few questions about nxt if someone could clarify that'd be great.

When I click the peer tab it shows a list of not only names but IPs is this just people hosting or everyone connected to the network at the time?

Why Java? Java often has exploits, it's not something most people want on there pc.

Security, is it being worked on? Even if you don't want usernames, two passwords would be a drastic improvement. Even possibly a second password where it asks you 3 random characters of it, like character 1,4,7 like some online banks use.

Nxt forging, correct me if I'm wrong but when I see the unconfirmed transaction tabs all transactions seem to have a 1 nxt fee, regardless of the amount, based on that it doesn't seem to make sense why the bigger share holders forge drastically more, maybe it should be transaction based? The more you send and receive the bigger chance?

Will there ever be an offline wallet?
Thanks in advanced for any reply, what I said above wasn't supposed to be negative. I bought some yesterday as I think it has potential, it just needs work.

My understanding of NXT is far from perfect so somebody correct me if I'm wrong but here goes.  

The peer tab only shows the subset of nodes that are in your "peer group", not all that are connected.  This list will grow the longer you stay on with your client and are eventually "discovered" by other nodes, one guy got up to 3000+ I think before his client crashed.  The client is continually being updated to have fewer bugs/memory leaks/etc  and is running longer and longer with each version number.  NXT is only a couple of months old, so creaky code is a given at this point but is getting better and better.  

Security is a hot issue and there will be upgrades in the user security interface as new clients are introduced (at least, I sure hope so) - keep an eye out on Solaris, our best hope for a new user friendly client.

Choosing who prints the next block based on transaction quantity would not be a Proof of Stake system as NXT currently is, it would be a Proof of Transaction Quantity system.  Proof of Stake is the method used to assign trust levels here, presumably people who own more NXT have a bigger stake in seeing the system run smoothly that those who own less NXT.

If there ever was a NXT wallet, it would be an illusion for general public users.  NXT is a brainwallet, all a user's NXT is stored on the encrypted blockchain itself and not in a separate file that can be taken offline and stored in a bank safe deposit box.  This is why long 40+ random passwords are so important - with NXT your holdings are available to you anywhere at any time, but they can be attacked continuously by hackers as well.  There is no hiding your NXT away from others offline, it is always in the cloud.

Welcome to NXT - new users like you are the only hope we have at success.  Head on over to https://nextcoin.org/ to dig deeper into NXT!

when is the nxt distributed exchange going to be up and running?

When the community tests it and is satisfied with the result.

Very nice work ebereon, any idea of the price for all?

Thanks all, building this is fun  Cheesy

Cost/parts of the solar powered RasPI NXT node:
- 1 x CombiBox incl. Solar panel + 1x Empty battery box:             €69,78 EUR (price can be optimiced!)
- 8 x Panasonic NCR18650B 3,6V 3400mAh !!!UNPROTECTED!!!(€6,90 EUR):    €55,20 EUR (best price!)
- 1 x Empty battery box:                               €12,95 EUR (price can be optimiced!)
- 1 x Raspberry PI model B:                            €39,95 EUR (price can be optimiced!)
- 1 x USB Adapter cable mini B-plug - A-plug(connection battery boxes):         €8,95 EUR (price can be optimiced!)
- 1 x USB Adapter cable mini B-plug - A-socket(Solarpanel > battery box):      €8,95 EUR (price can be optimiced!)
- 1 x ISY IWL 2000 Wlan Adapter:                        €19,99 EUR (price can be optimiced!)
- some time to set RasPI up
Done!

Not optimiced complete price is €215,77 EUR. I bougth everything from time to time over some month, not only for NXT Wink

Please do not complain about the price, this is not a consumer product! RasPI is a dev board and so are the components of this prototype. If you need a offgrid RasPI, then this is what works > 30 hours without sunshine!

If you build 100 of em, the optimiced price would come down to half or more Wink

Greets,

I don't really come from outer space.
Separately, would it be possible to get an API call that somehow implements:

The client (spender) generates a CoinSpend signature on the transaction that includes the hash of the transaction as well as the Accumulator and PrivateCoin object. The resulting CoinSpend embeds both a coin serial number and a set of zero-knowledge proofs that prove (A) that the spender knows a coin in the transaction set, (B) that the serial number is consistent with the coin, and (C) the spender knows the secret values for the coin. These are all tied to the transaction hash. The client (spender) serializes the CoinSpend object and transmits the completed ZEROCOIN_SPEND transaction to the network.
[from https://github.com/Zerocoin/libzerocoin/wiki/Integrating-with-bitcoin-clients]

The above needs to trigger a NXT payment from some magic acct that previously received NXT. I just can't figure out the logistics of all that.
...and...

Please let us know when you have any details on this, I will feel much better about zerocoin port knowing the exact mechanism for this. Maybe it has to do with special account 0?

Back.  Had to take a nap, it was very late on the US east coast.

Let's say we agree that the cost of a zerocoin-nxt, which we'll call ZNX here for short, is 10 NXT.  

When we generate a ZEROCOIN_MINT transaction, we send 10 NXT to a special account and receive (genrate) 1 ZNX in return.  Our generated ZNX has a unique serial number only we know.

When we generate a ZEROCOIN_SPEND transaction which reveals the serial number to the network, if the serial number is not already revealed in the chain we receive 10 NXT from the special account.

This is how I understand it so far.

Also, a special account may not be needed since it may actually be redundant information in the network.  Depends on how tightly we want to couple the zerocoin concept with the Nxt software. (Also depends on how comfortable people are with the illusion of NXT seemingly disappearing and reappearing on the blockchain when a zerocoin transaction happens.)

Truth is a consensus among neurons www.synereo.com
I made a withdrawal from DGEX, and not only do those asses take a 1.4% withdrawal fee, it's now been a few days and I still haven't seen my money. It took them two days to approach me by mail - the one I signed up with - and they're asking me to deposit more money to prove my identity. Two more days have passed since, a day since the last communication.

What the fuck? What a terrible exchange.


There's a notice that your account might be locked and put under investigation if you (or someone else) is trying to send money to a new account. I feel safe with such rules.

I dont feel save when someone keeps my money for "investigation"
better use BTER = professionals

Well, 2 step authorisation is better, but we have what we have. Since Dgex doesn't have 2SA it'll be better if they at least look for withdrawal addresses.

is not my problem.
I prefer use professional services, like BTER.
To sum up,DGEX is shit.

thousends of people "investigated" ..keeping their money for weeks... wtf..  i will stay away from this shit

They are now asking me to send them my password in cleartext by mail.
What the hell.

apart from the extortionate fees that are killing it, DGEX is fine. ive transferred allot in and out and never had a single problem. i suggest you use the BTC instant withdrawal.

On the same note, can I suggest that you get some panel mounted IO ports. Like this panel mounted USB port - http://www.adafruit.com/blog/2012/08/23/new-panel-mount-usb-cable-b-female-to-mini-b-male-and-panel-mount-usb-cable-b-female-to-micro-b-male/. One for the ethernet cable and solar panel connectors would look great too.
...
Also, purely from an Electrical Engineers pedantic perspective - I would mount a small fan running at low RPM on one of the sides of the box to prevent the entire thing from overheating.
...
Even removing the casing from the batteries might make the whole thing look a little bit cooler (by doing this you can access their power switches then, such that you could daisy chain the power switches to one master switch mounted on the front of the box).
...

Well, I wont turn this into a Barebone/Desktop computer. This is just a "chep" solar powered RasPI, nothing more. If I would add all these things, it would become expensive and time consuming. Open the battery case can be done at the conference to show off. A fan would take ~ 1 Watt more, that would kill the complete idea. Temps in the sun are ~ 63°C, so nothing to scare about.

A couple of NXT stickers on the sides of the box, line the insides with strips of LEDs, a bit of cable management and it will look amazing. It's the little things that make a setup/prototype like this. From experience, if you're going to do this you have to do it right and not have it look hacked together. That will scream the wrong message at people - "You can only do something like this if you are a genius".
...

It is still a prototype, but what about this photo? I leave the stickers done by the conference people Wink

@ AE client devs:

What input parameters do u need to get trade history? Is "asset" enough? Maybe range of block heights?

yes please! range of block heights with '0' for all would be extremely nice!

I had an idea about address format.  Maybe something to visually distinguish a NXT address from the many other crypto addresses… it can also "brand" our addresses so clones of NXT would most likely need to change this to look different.

something like:

Nxxxx xxxx X xxxx xxxxT

it might also just make you feel comfortable that you copied/pasted or typed your whole NXT address… you see the beginning, middle, and end.

I just know that I have copied/pasted a lot of various crypto addresses for different currencies such as with Cryptsy and they all look the same and I've wondered if I pasted the an address for the wrong coin.  Different credit cards start with different numbers Visa starts with 4, MasterCard starts with 5.  A lot of ID number for various things always start out the same so you can say look for a number that starts like…

I'm not sure if people think this is cheesy or unnecessarily adds complexity?... But I don't think it is much of a big deal to type a couple extra letters because people will often use QR codes or if they really want convenience at expense error checking they can send to aliases.

Maybe this may even stop someone from accidentally sending NXT to an address that was actually for a different or cloned crypto but still passed the basic NXT error checking.  We definitely need to change address format at some point.  The numerical address with no error check is a nightmare if NXT was used on a large scale.


Thoughts?  NxtChg, I know you were working on address format, what do you think?
