Nxt :: descendant of Bitcoin

Nxt uses brand new software.  It’s not a fork of Bitcoin's source code.

Nxt is the first 100% Proof-of-Stake (PoS) currency.  Coins are earned solely by charging transaction fees.  Unlike other currencies with PoS mining, Nxt's PoS mining does not cause monetary inflation.  The total amount of Nxt in circulation is 1 billion.  Nxt is resistant to +90% attacks via it's transparent mining algorithm.

Nxt improves different features of Bitcoin, removes some disadvantages (e.g. bloated blockchain) and resolves a big environmental issue.  Time between blocks is one minute.  This increases the rate of orphaned blocks but makes it more convenient for the users.

Nxt doesn’t use so-called “scripts” aka predicates.  This simplifies and accelerates transaction processing.  Advanced features like multisig will be created on top of the core as 3rd party services.

Nxt will have the following features:
- Decentralized Asset Exchange / Colored Coins (Starting after block 30000)
     This allows gateways to issue other currencies (fiat or crypto) on the Nxt network.
- Decentralized Marketplace / Auction
- Decentralized Mixing Service
- Encrypted Messaging / Chat
- Decentralized DNS / Alias System (Starting at block 22000)
- Transparent Mining (Partially starting at block 25000)
- DDoS Protection - Project Kharon
- Voting

Nxt IRC Channels
FreeNode #nxtalk
FreeNode #nxt-otc (Trading)

Nxt Forums
Nextcoin.org
NxTalk.org

Nxt Buying / Selling
DGEX.com - Nxt / Btc Exchange (thread)
Later, there will be a Nxt / Btc exchange integrated into the Nxt client.

Full source code will be released Jan 3rd, 2014.
Partial source code is available here.

Install Instructions

How to Install Nxt Client w/ Pictures

Ubuntu/Debian
1 - Download and Install Java                     'sudo aptitude install openjdk-7-jre'
2 - Unzip 'nxt.zip'                                        'unzip nxt.zip'
3 - Go to your Nxt Directory                        'cd nxt'
4 - Start Nxt                                                 'java -Xms512m -Xmx1024m -jar start.jar'

Windows
1 - Download and Install Java                      http://download.oracle.com/otn-pub/java/jdk/7/jre-7-windows-x64.exe (64-bit) or http://download.oracle.com/otn-pub/java/jdk/7/jre-7-windows-i586.exe (32-bit)
2 - Unzip 'nxt.zip'
3 - Go to your Nxt Directory                        'cd C:/PATH_TO_NXT_FOLDER'
4 - Start Nxt                                                 'java -Xms512m -Xmx1024m -jar start.jar'

Mac
1 - Download and Install Java                     http://download.oracle.com/otn-pub/java/jdk/7u45-b18/jre-7u45-macosx-x64.tar.gz
2 - Unzip 'nxt.zip'
3 - Go to your Nxt Directory                        'cd nxt'
4 - Start Nxt                                                 'java -Xms512m -Xmx1024m -jar start.jar'

Open Nxt Client
- Open your browser and go to http://localhost:7874 or https://localhost:7875
- Click the "Lock" icon in the upper left corner to unlock your account.
- Enter your passphrase or if you don't have an account, enter your new passphrase.  Make sure you use a very random, complex password of at least 30 characters.  You can use 0-1, a-z, A-Z, special and national characters.

Security Tips

- Do NOT run Nxt on a VPS.  Only run Nxt locally.  Even if you connect to your VPS securely via SSH, you are still not safe because all VPSs have backdoors.
- 7874 (tcp) is used for P2P communication, the http web client and API commands.  This is the only port that needs to be open to run Nxt.
- 7875 (tcp) is used for the https web client.

Russian Thread by abctc

Hi,

I want to report that I got an error when installing the JRE under OSX and lauching nxtcoin.
To work around this, I simply install the JDK that you can recover here:

http://download.oracle.com/otn-pub/java/jdk/7u45-b18/jdk-7u45-macosx-x64.dmg

Thanks.

Now that you mention it... should they invest in some SSL or something similar?!?

Looking at their interface I suspect their server is written in Fortran. This protects much better coz noone knows how to hack Fortran-based sites. Smiley

Hi CFB;

I put in a request for an alias and received what I thought was a confirmation with a transaction ID.  I looked at the transaction URL but it said "alias unknown".  However, today when I looked at the list that someone posted here it appears as though someone else who bid the same amount as me received the alias instead of me even though the server returned a transaction ID.  I'm wondering what happened.

Put hosts listed in lastBlockchainFeed about into "wellKnownPeers". Set other parameters to:

connectTimeout = 2000
readTimeout = 2000
pushThreshold = 1
pullThreshold = 1
- may be we need to set
pushThreshold = 500000
pullThreshold = 500000
in order to use only Hallmarked nodes?  to diminish the attack ?

500 seconds too much
- doesn't  pushThreshold define the hallmark weight ?  not seconds?

pushThreshold is weight.
- so didn't you and BCNext invent Hallmarks exactly in order to fight against Application level attack ?

doesn't we need to put higher value into pullThreshold, in order to bypass the attacker's requests?

Great. Don't forget to put ur IP into myAddress in web.xml. Also put a hallmark on it, this helps a lot.

Ddos is incoming requests, push and pull r for outcoming ones. Also it targets Jetty core, not Nxt servlet.
