1.1 What is Nxt?
Nxt is a blockchain platform with multiple core-level features that has been running publicly since late 2013. It is coded from scratch in Java, unlike most of the other platforms launched at the time. It's 100% Proof of Stake, meaning that the more NXT you have the higher chances you have of processing the next block. Because it's not dependent on computational power, a full node can run on something as light as a Raspberry Pi. Only 1 billion tokens were created and since there is no inflation, there will be no new coins created. So, when blocks are forged (Nxt terminology for mining) only the transaction fees are given as a block reward.
1.2 Was there an ICO for Nxt?
Yes. Actually, when BCNext, the anonymous creator of Nxt, held the ICO, it was one of the first ICOs in crypto with a total of about 21 BTC collected in late 2013. At the time, this was worth around USD 6000.
1.3 What is Jelurida?
Jelurida BV is the corporate entity of developers and owns the IP rights of Nxt, which is currently released with a GPLv2 license. It was created in 2016 and provides licenses for private versions of Nxt as well as consulting and modification services to interested parties. However, Jelurida will not do so for chains that would compete against Nxt. The current active core developers are all part of Jelurida. They are: Jean-Luc, Lior Yaffe (Riker), Petko, Tomislav Gountchev (Berzeleus), and Ronald Hoffman (ScripterRon), in addition to Kristina Kalcheva, their legal expert. Members of Jelurida have regularly been at events, whether as an attendee, an exhibitor, or as a speaker, and continue to do so. For more information about Jelurida, visit their website at Jelurida.com
1.4 What is the Nxt Foundation?
The Nxt Foundation was created in 2014 when some members of the Nxt community came together at an event and decided to present themselves under that banner since there was no entity surrounding Nxt at that time. It was officially established in 2015 as a nonprofit in the Netherlands (Stichting NXT) to be the primary point-of-contact for businesses wishing to use Nxt and raised the equivalent of about EUR 70 000 in donations in the TNSEE campaign. Though funds from that campaign still remain beyond the 1-year estimate, most of its funding today comes from the Supporter Program. Its role has since evolved into supporting the community through the creation and moderation of community channels, such as the NxtChat Slack Team, the Nxt subreddit, and Nxtforum.org, as well as the maintenance of Nxt.org and social media accounts, among others. It also helps interested project leaders, businesses, and organizations with the use of the technology. Like Jelurida, the Nxt Foundation also regularly has a presence at events in a similar capacity. For more information about the Nxt Foundation, visit their website at NxtFoundation.io
2 Nxt FAQ
2.1 Where do I get started?
2.2 What wallet/client should I use?
We recommend using the Nxt core client which you can download from Nxt.org.
2.3 Is there a light wallet/client?
There is no dedicated light core wallet/client, but you can activate a light mode in the Nxt core client this way:
- Locate directory nxt/conf.
On Windows it is here:
/conffolder under the root installation
- Create a text file nxt.properties in this directory with a single line:
- Start the Nxt client and it will not be downloading the blockchain, which will be accessed using public nodes.
2.4 Is there a mobile wallet?
There is one for Android which you can download from Nxt.org. No iOS wallets at the moment.
2.5 How do I set up Nxt on a Raspberry Pi?
2.6 How do I get NXT?
Here's places where you can get NXT with CNY, EUR, USDT, BTC and other currencies.
- To buy NXT directly
- Centralized Exchanges
- Direct Conversion Between Cryptocurrencies
You can also use the Shapeshift integration within the Nxt client itself.
2.7 What is the size of the Nxt blockchain?
As of May 2017, the Nxt blockchain is less than 3 GB.
2.8 What is the roadmap of Nxt?
There currently is not one publicly available for Nxt. However, Jelurida may release one soon after the launch of Ardor.
2.9 Where can I find more detailed information about Nxt and its features?
We recommend taking a look at this Wiki for detailed information. Start in the Features section of the main page.
2.10 Where do I find news about Nxt?
Nxter magazine provides weekly newsletters about Nxt and topics related to it such as important announcements from Jelurida and the Nxt Foundation, 3rd party projects, community developments, event participation, and other news.
2.11 Where do I find information about the API?
Information about the API can be found on the API page of this wiki.
2.12 What features does Nxt have?
Nxt has numerous core-level features such as the ability to issue assets, which are tokens on Nxt that use NXT for transaction fees, a decentralized asset exchange, decentralized voting, shuffling (for anonymity), alias system, decentralized marketplace, multisig capabilities, and a monetary system for currencies. For more information you can start in the Features section of the main page on this wiki.
2.13 How many nodes are up for Nxt?
PeerExplorer is a great tool to see live information about nodes.
2.14 Where is the source code?
You can find the source code in Jean-Luc's Bitbucket.
2.15 Where can I get the changelog?
You can download the changelog by clicking this link.
2.16 Does Nxt have a testnet?
2.17 What projects are currently using or testing Nxt?
There are multiple projects currently using or testing Nxt utilizing one or more of its features. A comprehensive list is not possible to be made as there can be projects running on Nxt that even the core developers will not be aware of due to the decentralized nature of Nxt. There is no permission needed to use Nxt. In addition, since it is open source GPLv2, people may be testing it in a private research environment without anyone in the community knowing. Additionally, projects may be abandoned without the knowledge of the community, or have gone into justified "hibernation" status. However, that said, here are some resources which you can use to see which projects are running publicly on Nxt:
- Nxtforum - Assets Board
- Nxtforum - Community News & Announcements
- Nxtforum - Projects
- Nxtportal.org (Assets & Currencies Blockexplorer)
- MyNxt.info (Assets, Currencies and Marketplace Blockexplorer)
- Nxter Magazine Asset Hub
2.18 How do I access my MyNxt account on the Nxt client/wallet?
Please follow these instructions to see how you can do so. Your MyNxt Master Password is likely not the same as your Nxt account passphrase.
3 General Software Questions
3.1 Why am I getting a Java error when I try to start the software?
Nxt relies on Java 8. Make sure you download and install latest version installed from Oracle! You can check to see which version of Java is running on your computer by running the following command in a terminal window:
3.2 Why cannot I open the client in a web browser?
First of all, you need to make sure that the Nxt server window has finished loading, as indicated by a message like this:
Nxt Server 1.11.5 started successfully.
To access your client interface, you can then use either of these addresses:
3.3 Why doesn't my blockchain finish loading?
Patience is usually the best fix; your client will eventually catch up with the network. Some delay may occur specially when you have updated to a new software version that performs a database upgrade.
3.4 Why do my blockchain files keep getting corrupted?
The blockchain database may get corrupted as a result of the Nxt software being forcefully terminated, in a way that doesn't allow the server to close the database properly. You should be able to see "Database shutdown completed" in the log before shutdown, as a sign that data files have been properly closed. To prevent data corruption when closing Nxt:
- In Windows, use Ctrl-C to shut down the process in the terminal window
- In UNIX, use
kill -15 #ID PROCESS.
4 Account Questions
4.1 The client says I have 0 NXT in my account but I have not transferred my coins anywhere
In some cases, right after unlocking your account in the client, the balance might momentarily appear like zero or a different amount than expected. This will happen if the blockchain has not been completely downloaded by your software yet, and the blocks containing your deposits are yet to be downloaded. Check the time stamp on the latest block in the "Blocks" panel. If it is not very recent (within a minute or two), wait and give the software some time to catch up. Your balance should match the balance showing for your account in the blockchain explorer in a few minutes.
4.2 I'm trying to unlock my account, but I keep accessing a different account number than the one I created. What's going on?
Since different account numbers are accessed using different passphrases, getting a different account number than the one you expected means you used a different passphrase than the one originally used to generate your account number. Make sure you are introducing your original passphrase correctly. This means double-checking for typing mistakes, and ensuring no extra spaces are accidentally pasted (or omitted!) in the beginning or the end of your passphrase as you paste it to unlock your account.
4.3 I created an account. Why cannot I see it referenced in the blockchain?
In general, you can use a blockchain explorer to search for your account, examine your balance, transaction history, and more. Information about your account will not appear in the blockchain until there is at least one confirmed transaction that references your account. This is because the blockchain is a record of transactions, not account information. If you have created an account but have never sent any Nxt to it, the account will not appear in the blockchain.
5 Post-Ardor FAQ
5.1 What will happen to Nxt after Ardor launches?
Nxt will continue to be developed by Jelurida. A portion of the funds from the Ignis ICO will be going towards Nxt development as well.
5.2 What will happen to my Nxt account after Ardor launches?
Though aliases, assets, currencies, NXT, and other things will stay on your account, some projects may choose to move, such as assets that are moving to Ardor. If you are following a project closely and are interested to know whether they'll stay on Nxt or move to Ardor, please ask the respective project team or leader. However, if they are migrating, please be aware that no official announcement has been made yet about the migration process.
5.3 How do I migrate my application to Ardor?
If you want to migrate your application to Ardor, please refer to this guide.
5.4 What does Nxt have that Ardor will not?
When pruning is activated, intended to address the blockchain bloat issue with multiple chains powered by Ardor, only transactions on the Ardor main chain (ARDR) will be kept by all full nodes. Most of the features found on Nxt will not be found on the main chain and only on child chains like Ignis. However, because of pruning, child chain transaction records will be snapshotted (to continue on from the pruning point) then pruned from full nodes after every 1440 blocks (~24 hours), though secured cryptographically on the main chain blocks. Basically, with Nxt, all full nodes keep all transactional data, while on Ardor only archival nodes will for the child chains. Other features and use cases may utilize this for purposes unique to Nxt.
