NXT :: descendant of Bitcoin - Updated Information

[swartzfeger]

This is a surprise: Cross platform NXT client launched by DGEX in Twitter:

http://offspring.dgex.com/

OFFSPRING WALLETS

Offspring stores your NXT private keys (passphrase) together with your Offspring account label in an encrypted file,
we call this file your wallet.

When Offspring starts you must either enter the password for your existing wallet or create a new wallet by entering
the password for your new wallet twice.

By default Offspring offers to unlock or create a wallet called 'offspring.wallet' which is in the directory that
contains your Offspring executable.

Great catch! Downloading now...

You guys sure are quick!  Here's the full scoop.

DGEX is proud to present Offspring - The Cross-Platform 2nd Gen Crypto Client.

Offspring v0.2a system requirements:

Java 1.7 required (if you already run official NXT client NRS, then you already have java)

http://java.com/en/download/manual.jsp

Operating system: Windows XP, Windows Vista, Windows 7, Windows 8, Ubuntu, MacOSX
Program to open/extract installation zip file (first try and double click the zip file,
if that does nothing use http://www.7-zip.org/)

Download (select your operating system below):

http://offspring.dgex.com/offspring-w32-w64-blockchain.x86.exe (Windows, easy install with blockchain included)
SHA-1 C807446737534CC7E869553DF802218168A3683C

(Windows, SHA-1 5DFE403DEEDA7291C73F668AB34B4FFF4022DCAB)

http://offspring.dgex.com/offspring-linux-gtk.x86.zip
(Ubuntu Linux, SHA-1 6E5D8D7451F9E59BB47661417EC16A80C6DC8C06)

http://offspring.dgex.com/offspring-linux-gtk.x86.zip
(MacOSX, SHA-1 C660D6645330CA2650996458A8A957313BC47F53)

Installation:

Download the one click installer with blockchain:

http://offspring.dgex.com/offspring-w32-w64-blockchain.x86.exe

After download double click on the file and follow instructions.

OR:

   - Download the zip package version for your operating system (Windows users same version works for both 32 and 64 bit Windows)
   - Create an Offspring folder on your hard drive (we recommend C:\Program Files\Offspring).
   - Double click the zip file you just downloaded, now select all the files and folders contained in the zip file and drag them
     to your freshly created Offspring folder.
   - Now double click your C:\Program Files\Offspring folder, then double click offspring.exe, have fun

First time use:

    If used first time without blockchain included, Offspring must download the blockchain files.
    You can watch download progress in the Advanced section by looking at the Recent Blocks panel.

    Once you downloaded (a good part of) the blockchain it's best to switch off Offspring and then turn back on again,
    this way you force NXT to save the blockchain to your hard drive,
    later versions when NXT is open source will not require this.

Offspring main features:

   * Cross-platform, the same source code is compiled for various platforms.
   * No web browser required, works offline
   * Latest NRS engine is embedded
   * Connect to local or remote NRS engine

   * Control multiple NXT accounts from single interface with one master password

Support for basic NXT features and more:
    * Send money
    * Assign alias
    * Create token

    * Validate token manually (for merchants)
    * Sortable full transaction history details
    * Advanced network status view section: recent blocks, orphaned blocks, active peers, known peers, blacklisted peers
    * Quick blockchain download during which accounts can be used for operations
    * Forging on by default for all included accounts
    * Security features: encrypted accounts "wallet" file in user settable location (eg. USB stick)
    * Display of total NXT holdings value in BTC and EUR according to latest rates and chart direct from DGEX
    * Realtime BTC / NXT market rate and chart with level 2 full order depth from DGEX.com

Major features coming soon in later versions:

    * Multicurrency client, incuding transfer capability for some of the other major cryptocurrencies
    * Asset Exchange, trade NXT or any other assets directly peer-to-peer from the client without third party web sites
    * Full block explorer with search
    * Encrypted p2p messaging
    * Transaction memos

Offspring will support all current and coming features of NXT.

Why use the authentic NXT client to store your NXT instead of third parties, for instance your DGEX account?
Consider the following points:

    - The client enables you to own and operate a genuine NXT account with a few clicks of a mouse
    - Take full control of your NXT so you can sleep your nights well even if your favorite exchange has service interruptions
    - Send NXT instantly to another account or merchant
    - Create tokens for use on merchant sites without the need for extensive server configuration
    - If you are a merchant, verify customer payments through tokens manually without the need for custom software
    - Participate in strengthening the NXT network and be eligible for random forging rewards automatically by
      just keeping your Offspring client on.

OFFSPRING WALLETS

Offspring stores your NXT private keys (passphrase) together with your Offspring account label in an encrypted file,
we call this file your wallet.

When Offspring starts you must either enter the password for your existing wallet or create a new wallet by entering
the password for your new wallet twice.

By default Offspring offers to unlock or create a wallet called 'offspring.wallet' which is in the directory that
contains your Offspring executable.

You do however run the risk that future malware or hackers will try and steal that file from your computer,
even though that file is encrypted that does not mean it can't be cracked given enough time and computing power.

For enhanced security Offspring offers the ability to select what file is your wallet file. You could for instance
insert a USB thumbdrive and from the login dialog browse to that USB thumbdrive and then select which file is your wallet file.

You must remember what file is your wallet file since we don't store any reference to it.

Offspring does not care about the name or extension of your wallet file and if it's set to read only or maybe hidden.
You could name your wallet 'funnycatpicture.jpg' or 'taxreturns.doc' and Offspring will happily unlock and use that.

Another possibility of selecting your wallet file is that you can use multiple wallets each containing different
NXT account private keys.

Offspring can run in local or remote mode.
When run in local mode (default) Offspring will run an embedded webserver on your computer
and in that webserver Offspring runs the official NXT class files (java servlet).

Offspring can also connect to any other server that runs the NXT servlet.
The address of the server is set in a file called 'offspring.config' which is a so called java properties file,
the property is called 'remote_address'.

If you used to run the official NXT client you could use Offspring to connect to that.
You could also run your own NXT node on a server and connect to that from your local computer.
We use this feature to connect to the test net while developing for the Asset Exchange.

Example to connect to the AE test net:

remote_address=http://holms.cloudapp.net:6874/nxt

Example to connect to official NXT client running on your own computer:

remote_address=http://localhost:7874/nxt

Warning! Upon connection to remote NRS server Offspring will send your NXT account private keys to that server.
Make sure you trust that server.

Enjoy!

WOW great job to Graviton!

It's interesting and think some folks will like it. Multiple accounts + wallet is cool, alias support is nice. Some minor things don't work in OS X version (cmd-Q doesn't work nor does Quit menu item; must close window).

Biggest thing is my acct balance is incorrect due to old blockchain. Tried deleting to download a fresh copy but that didn't work. Think I'll pass on this and stick with Wesley's excellent Mac client.

edit: Graviton, your Mac link works correctly but says it's for Linux. You should change the text.

*** IMPORTANT ***

I just spoke to Mike over at Vault of Satoshi, they are ready to implement us.


** What I need **

We need to make it very easy to implement NXT on exchanges. Could someone please send me the right information to send to VoS to get them started?

[lucky88888]

Sometimes I feel a bit frustrated about the fee-system of Nxt, when I see these kind of blocks passing by:


Fee = 0,0016%


Fee = 33,33%

It's not really fair and the rich are getting even richer this way. I love Nxt, but there are small flaws which needs to be addressed. The critics will talk negative about Nxt because of these kind of issues. 

Maybe a percentage instead of a fixed fee? Curious to hear about the options.

I dont think approaching anything from the "rich getting richer" is a good idea in a 100% POS system.  IMO though fee should be based on transaction byte size.  And even if it were based on scale of larger transactions = larger fee, the 'rich' are more apt to mine those higher fee blocks anyways.  There just doesnt seem to be a way to prevent the 'problem', as it were.  Regardless, 'the critics' wont matter the more and more NXT features are released.

The real concern here is people just giving up forging, or centralizing their forging power into central pools.

Well, can't see why a percentage would be bad.

Centralization is an issue. How do we counteract?

What centralization? CfB said that there will be no use of forging pools once we get Transparent Forging fully implemented by April. Right?

Great.
Can you expose the detail of the conversation with VoS?
For example , how do they think of NXT?

[jl777]

I am sensing a generally positive reception to the community backed gateway concept, contingent on solving the technical details.

Since I am not seeing any specifics on how we can actually do this, I will post a ROUGH DRAFT idea of the tech pieces that are needed. Any improvements are definitely welcomed.

During a global Ddos attack like now, some websites are inaccessible, but NXT networks seems to be fine, a bit lagging but functional.

The gateway will be running NXT node as well as all the other altcoind's. This gives it access to AM. In order to not require the keeping of account databases, I am willing to live with a slight delay on deposit and withdrawal.

I realized that by issuing 1 billion units of an Asset and sending the exact amount of Asset received would give 100% backed Assets and you can tell how much should be there by the difference from 1 billion. There is the issue of lack of precision, which requires a min lot size to be determined for each crypto, but this is a small detail

Deposit: AM is sent to gateway acct with type of deposit, source wallet number, amount and destination NXT acct to receive the Asset. gateway parses this AM and returns an AM with wallet address for this deposit and waits for the appropriate blockchain to show that the deposit has come in. When it does, it transfers the received amount of Asset to the specified NXT acct.

Withdrawal: AM is sent to gateway acct with type of withdrawal, dest wallet number, amount and source NXT acct that will be sending the Asset. gateway waits for Asset to arrive and then transfers the coin to the designated wallet. AM is sent to source NXT acct with transaction ID.

A small amount of client code is needed to handle the AM messages and once we get this done it can be a universally available feature. As long as NXT network is running, the gateway requests will get to the gateway server. We just have to make sure the gateway server is always running.

Notice that the gateway server does not have to keep a database of user accts, just the pending transactions. it can always rescan the blockchain to figure out what transactions are pending. More importantly, it is public data so everybody can verify that all the deposits and withdrawals are happening.

Any volunteers to code the server side? The client side? We can develop the tech while we are figuring out the trust issue.

I also think there is a solution for the Asset name issue. Since it is likely that in the landrush for Asset names, "BTC", "DOGE", etc will all be taken. My solution is to just have a random prefix/suffix that is available for all the desired Asset names and then when the client software is presenting the orderbook for the available Assets, it would just strip off this random number.

Did I miss anything?

I've worked with Mike getting Peercoin implemented on VoS. I simply sent a follow-up email, introduced him to the different developers we have in the community and let him know we're committed to working WITH exchanges to help drive traffic. I mentioned we are right under Peercoin at about 50 million... that's all that was needed.

There's a lot to be said about attending conferences and spending time making connections in the crypto community. I hope to leverage everyone I've met since Feathercoin in the coming weeks. Now that I have a team of guys (CoinTropolis) eager to help push Nxt forward, I feel we're in a great position!

http://www.cryptocoinsnews.com/2014/02/13/the-mathematically-secure-way-to-accept-zero-confirmation-transactions/

Can someone more technically adept than I am (that would be any of you guys) comment on this, please? The claim about zero confirmations seems to imply that short times between blocks is far less important than network hashing power regarding prevention of double spending. Is his analysis correct? And are there implications for NXT?

[rickyjames]

Berlin (2)
Hive, BitAngels and Mastercoin guys, + many many others. We ale looking for a speaker at the San Francisco conf Everyone is so excited about Nxt, it is easy with nice T-shirts we have thanks tu admiral.fu

Texas guys are here, so the speaker is for sure.

Still only 2 Barbie girls, so not much fun, only business talks...

About those Texas guys - please find Paul Snow and ask him to verify me as a speaker for nxt in Austin.

yes we spoke with Paul a few times for quite a lot of time... It's settled up... I even had to sign some papers with my blood

Good job...I think.  What exactly did you sign?  And...is he a vampire?

The claim about zero confirmations seems to imply that short times between blocks is far less important than network hashing power regarding prevention of double spending. Is his analysis correct? And are there implications for NXT?

From what I read it is basically using statistics to estimate the chance of a double spend happening. As more and more nodes see it, it becomes less likely for any chain to override this. I did not see any mathematical proofs about the accuracy of this method, especially how it would fare under a selfish mining attack. For example, a selfish mining group could have many blocks prepared ahead of time and even though it would be statistically unlikely, it could happen.

Since the article is talking about a statistical method, odds are good that it works, just not 100% guaranteed. Probably fine for small transactions, but if you are dealing with big amounts, just be patient.

As for how it affects NXT, I dont see much here to worry about. firstgen cryptos are still limited in the number of transactions, nothing close to 1000TPS would be in the cards for bitcoin anytime soon

<gateway stuff>

Nice work on getting us all started on this.  Keep in mind that for some assets such as BTC you could just imply a certain number of decimal points for more resolution.  Its times like this I wish I had gone the CS route in stead of the easier IT route in university - Im no coder.  Oh well, wish I could help out more.

But yes, the trust thing will be difficult.  Possibly some aspect of account control will assist here, whenever it comes out, since it looks like we will see account control instead of regular multisig.
