https://nxtportal.org/search/349998
https://nxtportal.org/search/NXT-WY9K-ZMTT-QQTT-3NBL7

WebGL visualization of nodes: https://nxtportal.org/globe

Testnet: http://test.nxtportal.org

Release history: https://nxtportal.org/history.txt

nxtportal.org started as a project to play with the Nxt API + Node.js.  I wanted to build a browser-based block explorer with as little as possible on the web server.  My goal has been to keep things simple, lightweight and fast. 

Please report any bugs/issues.

Do you know if there is an API method to get a list of all NXT accounts?

Added account number lookup.  Right now tx are loaded by block id, but I will add some more options to the api soon.

Edit - added txid.  :)

I hope to have the next version ready by tomorrow with account tx history and a lot more features.

Definitely a good blockchain explorer.
By searching "nxt blockchain explorer" on google this is what I get: https://i.imgur.com/wWukbHv.png, and it keeps going on the second page. Plenty of domains wasted pointing to one blockchain explorer. It kinda makes me sad.

Keep it running and I will keep using it. I have a few suggestions. It is my opinion, so feel free to disagree.
I think you should make the account details a little more clear. The first time I used it, it seemed it was not working, in fact I did not even notice that the information was being displayed. For starters I would put Account ID on top of Block ID and not the other way around. Secondly, when you search for something, the Account ID tile should blink once or something, letting you know in a clear way that the information got updated.
Which brings me to the third suggestion, when you search for an account (or a block) that does not yet exist, nothing happens at all. Which makes sense, since as I said they do not exist so there is nothing to display, but at least it should be clear that is the reason. I had to click "search" at least 10 times before realizing that what I was looking for did not exist (forgot one digit on the account number). You should find a way to express this "nothing to display".

Other than that, it is great!

Thanks for the feedback, some of the things you mentioned are already fixed/changed in the latest version that I will hopefully be able to push out tonight.  Stay tuned!

Just pushed the latest version that includes a lot of updates and initial account history.  Right now I have it set to display a max of 30 transactions but in the near future I will add transaction scrolling.  You can click on any transaction ID or account ID in the transaction lists to view details.

Edits:
- This version of the scroller has some display bugs and is notably inefficient compared to the prior version, but this will be resolved when caching is implemented
- scroller is fixed!  I spent the last few hours on optimizations and it's much better even without any caching yet.  :)

I just pushed the latest version with some new features.  API results are now caching in the browser and I think I've worked out most of the glitches.  The transaction details now display aliases, messages and lease info.  NQT balances are now displaying correctly in all places.  The search is working again and I will make the notifications nicer soon!

Thanks for all the feedback so far, please let met know if you find any problems/issues.

The UI is indeed looking sleek and useful but cannot we search account info,with the account names?
 NXT-9E2Z-J8XM-HKYU-G2GC2 does,not return any results as long as I'm not doing something wrong

The Reed-Solomon format got added recently, until he adds the support to it you can only search using the equivalent ID.

A few people have requested the ability to bookmark specific searches, so I added the ability search via generic search url that RS & numeric account ids, block height and txid.

I was never completely happy with the layout so I spent a few hours trying different arrangements.  I think this latest version (v0.1.4) is much better than before.  The accounts page seems to make more sense now, and the secondary account window now has buttons to close the window or make that account the primary.

Made a few updates this past week to speed things up significantly.  Some queries have been refactored and I set up a server side caching module so data will now persist between blocks.

Transaction lists are still limited to 50 rows but I'm considering doing an "bottomless page" view for them

Modified nearly all ajax queries to use the native API.  Still need to go direct to the db to get the # of blocks forged per account, as well as the latest transactions without fetching blocks.

I finally added the transaction pager.  You can use the left/right arrows on the keyboard or the left right pager icons.  Try navigating with the arrow keys, it's fun!

I refactored the API calls and cache again and removed all the db hooks, nxtportal is now running entirely on the NXT API!  :)

There is an asset list for accounts available, is that what you mean? If you click on the accounts page, the icon in the upper left of the transactions list will let you choose between account transactions, forged blocks and assets.



It's a bit hidden right now, perhaps I will change it.

I just pushed the latest version with some core changes on the backend as well as mouse wheel support.  The UI is very easy to navigate now and site performance should be very fast overall, especially now that gzip compression is enabled.

I made a lot of changes recently so if anyone finds any bugs or has any suggestions please post them.

Deployed (and re-deployed) v0.4.0 with MS filter for tx lists and currency views.  Please let me know if anything looks awry.  Right now the asset and currency selection lists are ordered by number of transfers + number of trades/exchanges but that will be changing soon.

Added a currencies list to the account menu and fixed a number of bugs.

The menu is easy to miss, it will be changing soon -

searching for asset names and currencies names would be great
just a javascript script for the client to filter the tables

I just pushed the latest version with URL routing finally implemented.  The back/forward buttons work properly and if you refresh it will stay on the same page.  I had to basically refactor everything (again) because I'm using native HTML5 history and it was painful to get everything working right across all browsers because they behave differently.

I will add this shortly, hopefully this weekend if time permits.  I was going to implement the search using the API, but doing a simple filter on the local cache is a good idea and will be useful in other areas too.  The only issue is that I'm not fetching all the asset/currency data locally.  The app only ever retrieves data that is being displayed (aside from a few extra blocks) to keep traffic as minimal as possible.  To see what I mean, view the network profile while paging through the currencies/assets.


nxtportal has become my favourite blockchain explorer. Very well done!

Thanks!   :)

I may move the unconfirmed transactions monitor to the forging page and revert to the old "recent transactions" page w/type filters to make it more useful for browsing testnet transactions without needing to scroll through (empty) blocks.

Hopefully I can find some time to add a polls/voting view in the next few days.

Version 15.4.14 deployed, transaction details are much improved.  The transaction page now has a recent transactions browser that shows the last 20 transactions for the selected type filter.  I may add paging to this later.  The unconfirmed tx list and forger list are now together on the monitor view.

New version is up.  I added a scrollbar on the unconfirmed tx list so the detail panel is always in view even with a lot of transactions.  Also added total forging stake to the monitor as well as a raw JSON link on each detail panel.  If you had a connected session you may need to do a ctrl-R refresh because some of the socket data formats changed.

There was fix in 1.4.17 that fixed a bug. Someone is still trying to exploit the bug in the stragglers that haven't updated.


Update to 1.4.17 NOW, to support the network.

Just pushed an update with some initial views for polls (will add more info shortly) along with some refactoring under the hood.

I'm thinking of adding some additional stats as well.  I'm open to suggestions if anyone has particular things they would like to see.

Poll views are very well done! BTW nxtportal.org is my favorite blockchain explorer!

You may remove the links to nxtblocks.info and hashrate.org from the info page, they are outdated.

Keep up the good work!

Links updated, thanks.  I just pushed a new version with refactored websocket config that is much more efficient.  I added some more info to the polls view and will probably move the bar chart to it's own window and add a list of voters. 

You may have to hit F5/CTRL-R to reload the page, reconnected sockets will probably be confused.

I've pushed the latest version with some significant updates to help the monitor stay in sync with NRS.  It should now resolve forks as soon as they are resolved on the back end.  I've also added a few stats and a counter for unconfirmed transactions, and the browser app will now reload and get software updates automatically.

Looking at the globe, it seems the NXT community had not put enough effort to promote diversity and ensure equal access for all people, regardless of their race. How else could you explain the relative absence of NXT nodes in Africa? And don't give me the standard "lack of infrastructure" excuse. Everyone knows that African people are every bit as brilliant and capable of great achievements when not held back by (Western) oppression, bigotry and racism.

NXTers must look deep into their souls and come clean of any conscious or subconscious actions (present or past) that could bring shame to this community. A good first step would be a donation to the American Civil Rights Institute (http://acri.org/) or directly to me at NXT-1111-KCUF-1EHT-TAHW

Fixed mouse-wheel zoom.  Also IP address geo data doesn't necessarily indicate the actual location of a node, e.g. nodes using tor.

Made some updates to async load the js libraries for the globe - three.js alone is 400k minified, no need to load that on every visit.  I still need to trim down the forger data but overall the base url visit is nice and fast again.

I've added a toggle to the peers list to show peers updated in 24h or all peers.  NRS was restarted after upgrading to 1.5.14 so it will take a bit for the peers list fill out again.

I also wrote a diceware passphrase generator and linked it in the resources section.  It is all in a single html page so you can save it and use it offline if you like, the only 3rd party code included is a sha256 implementation.  The code is easy to read and the outputs are logged on the screen so you can manually verify everything without too much trouble - https://nxtportal.org/tools/diceware_passphrase.html

Nice work on the blockchain explorer. Yours is my favorite now.  :)

May I suggest to add the account ledger history so we can see dividend, trade results, transfer and such diiectly from the explorer.

Thank you so much @coretechs for making this block explorer. It is by far the best block explorer for nxt out there.
I wish it could be integrated into the NXT client.

coretechs,

Would it be possible to add different time sections in the asset trade history chart here: https://nxtportal.org/assets/ ?
For example: 1 day, 1 week, 1 month, 12 months, all?

Would be cool to see all time asset charts.
It does not have to be as fancy as poloniex: https://poloniex.com/exchange#btc_nxt

I just finished a standalone webpage for generating and validating auth tokens using the curve25519.js code that is included with the Nxt client and a few additional libs (sha256 + biginteger).  It's basically a direct port of the NRS Java code, similar to the Jay client.  I've tested it with Unicode inputs for both the message and passphrase.

[nice way of taking over a discussion - but we're on nxt forum not  ;D]

Take the nxtportal site for instance since @coretechs is here. Thats one blazing fast nxt explorer you've got there.
Keep getting impressed by how fast it renders, truly amazing.

And it has a websocket backend (socket.io if i peeked correctly) thats all really cool stuff, this is what the kids like (aka fresh blood).
Why is that not on github.com/nxt?

Thanks!!  :)

The site does use socket.io, as you noticed, initially for unconfirmed transactions and eventually the forging monitor and other active content.  I thought about using it across the site but the version at that time didn't support stream compression and I didn't want to lose the benefit of gzip compression & browser caching.  It doesn't use any major frameworks, just doT.js templates and bootstrap/jquery for the layout.  Everything is cached on the server side and on the client side using a dumb cache that is emptied after each new block, so that can definitely be optimized in the future if necessary, but for now it works pretty well.

Nxtportal.org is currently offline, something very odd is going on with the server.  Working on a resolution once I find the root cause.

update #1: lost attached storage, currently rebuilding the server, should be ready in about 15 mins
update #2: back online!   8)

Would it be possible to implement short nxt addresses in nxtportal?
The thought came to my mind today when I had to look something up in my account NXT-CRPT-KEEP-R3DV-AXCDR. Wouldn't it be nice if I could only enter "NXT-CRPT-KEEP" and nxtportal would automatically find my account?

There is something similar in bitcoin: do you know the famous physical bitcoins by Casascius? They have a short btc address printed on the back of the coin, which you can look up with some blockchain explorer services, like blockr.io.

For partial RS accounts I think I'd need to query the db directly but I'd prefer to use the API.  I could add support for the searchAccounts API, that way you could search for account name/description, so for your account you would just need to search for "CryptKeeper", e.g. https://nxtportal.org/nxt?requestType=searchAccounts&query=CryptKeeper

For partial RS accounts I think I'd need to query the db directly but I'd prefer to use the API.

Account id's are stored as unsigned longs in the db.
The rs addresses are calculated from those longs.
You need to add an extra table to store the RS ids or you should write some java plugin that stores the RS address with each new address in for instance the account_info table.

In FIMK an extra table was added, it's also what we use for send money recipient auto complete suggestions.

Head's up!
You're about to undergo a sudden surge in traffic on your testnet explorer.  Please let me know if there is anything we can do help the spread the load.
https://nxtforum.org/democracy-counts!/introductions-join-ups/msg218445/#msg218445

Up until this moment I had assumed nxtportal WAS the official NXT explorer, otherwise I would have reached out much sooner!

I can't speak for the organization officially, but I know we have a little funding left over in our IT budget I can donate in order help you cover additional costs.  It's not a whole lot, but it might be enough to spin up some servers and acquire more BW.  PM me if you need anything at all.

(additionally, if this goes off without a hitch we'd like to talk about licensing this block explorer for custom projects, it's awesome!)

Nxtportal is getting crushed right now.  The H2 db is getting hammered and transactions timing out.  This isn't the first time I've seen performance degradation in the file system where the blockchain is stored, and in the past the only way to resolve it was to spin up a fresh disk volume.  Maybe it's time to upgrade the default VPS disk to a dedicated storage volume.  For now I'm going to reduce the frequency of the peer list & charts processing as that seems to be the primary cause of the timeouts.


The good news is that there are around 4x-5x more users than normal.   ;)


edit: ran some disk tests and everything looked ok, then discovered a thrashing bug in my job scheduler... easy fix, yay.

Since June 26 there has been a 10-20 times increase in trading volume (measured in USD). See coincapmarkets.com/currencies/nxt
One would expect that this had an effect on NTX/day and fees/day in the charts at nxtportal.org, but it doesn't. Which site is wrong, nxtportal or coincapmarkets ?

From my experience a lot of traders keep their crypto on the exchanges - even if this is a bit risky (see MtGox, Cryptsy)! I can partly follow their arguments: keeping it on an exchange enables you to react more quickly on sudden price changes.

The number of transactions/fees per day hasn't increased much, but zoom into the last few weeks of the "NXT Transferred Per Day" chart and you can see the increased activity.

Hello, is it a lot of work to have nxtportal.org show Ardor amounts before it's become a "normal" asset?

Not much work at all thanks to the getFxtQuantity API.  I just pushed an update that adds Ardor balance/expected in account details.   :)

I've pushed a new version with a long-overdue alias browser w/realtime search filter.  Please report any issues.  I'm still tweaking the keyboard input as it can be a bit glitchy.

I've been having some problems again lately with database queries timing out.  I made a few updates to the maintenance scripts that should hopefully help.

Hi coretechs,

How do you get the Active stake of forging NXT?

Thanks!

I take the distinct generators of the last 10,000 blocks to get the # of active forging accounts, then sum their effective balance.

Is anyone using nodejs and querying the Nxt H2 database?  It appears that some recent update broke the jdbc driver package as it can no longer connect to the H2 db without crashing with a segmentation fault.  I've been trying to get it running again for hours and at this point I'm probably going to disable some features in order to get the site working again.

Looks like the cause was a kernel security patch that broke node-java:

Hi,

A few day ago, when searching for JLRDA on the nxtportal.org, we ended up on the correct MS currency. At least it was possible to find it. Now the search end up on a scam asset and only that scam asset, and this even if we do the search in the currencies tab.

Would be good to fix this newly undesired behavior.

Thanks

The link https://nxtportal.org/resources/ contains outdated exchanges: Coinimal and CCEDK. Both do not offer NXT anymore. Please remove Coinimal and CCEDK entries from the resources list. Thank you.

Hotfixed a bug in the server that was triggering a restart under heavy load and updated Nxt to 1.11.11 in the process.

Things appear to be stable again, currently peaking at 2650 3800 4850 (!!!) connected sockets.

The Ignis airdrop turned out to be an interesting production load test for Nxtportal. Last night the server peaked at around 7000+ connected sockets. I really never expected to see this many users on the site; In the past I'd be happy to see 50-70 online from time to time. It was barely keeping up at that point, considering that everything runs on a single 2-cpu VPS w/4GB and the Nxt client was allocated 2GB of that. I got a lot of valuable debugging data from the logs, particularly a few spots where errors weren't being handled properly that resulted in the nodejs process restarting.  Whenever this happens, thousands of sockets reconnect and it pegs the CPUs for a few minutes. This is still happening occasionally but I'm planning to depoly fixes later this week instead of hacking together hotfixes as there are still ~3000 active connections.

To those of you who have asked, yes, I am working on a block explorer for Ardor. It is a complete rewite still in early development but at least you can browse blocks. Expect lots of bugs and updates at random times.

I just applied a patch that should resolve the issue. There was a manual lock that was not being released when handling an error condition.
