I have deployed additional nodes. I've been focussing on regions that don't have many nodes yet.

Total nodes deployed: 20

Regions:

South America (Sao Paulo, Brazil): 10 (nxt2.tweetmondo.com to nxt11.tweetmondo.com)
Australia (Sydney): 5 (nxt12.tweetmondo.com to nxt16.tweetmondo.com)
Malaysia (Singapore): 5 (nxt17.tweetmondo.com to nxt21.tweetmondo.com)

If you want more nodes in these regions, please donate 1000 NXT per month per additional node to: 9060914620736248721

Thanks!

ZeroTheGreat, remember that those are upper bounds on forge time.

A wallet that is unlocked 24/7 on an always up-to-date server will forge a block more often, because of the large portion of all NXT currently in locked accounts, lagging/stuck nodes (temporary phenomenon atm, though) etc.
No, that feature postponed. If 900M locked, 100M now'll forge like 100M. Later we'll have to say "200k unfrozen equivalent coins", and full amount can be any. Multiplier unthinkable now.

Really? That would mean that when 90% NXT are locked, forging would only go on at 10% speed. Sounds strange to me.
Look at statistics, we went to ~1440 blocks per day not so long ago. DDoS splitted network and calculatable low % of all coins was forging main chain with low speed against needed 1440/24h. I'm little surprised why "Transparent Forging" wasn't built-in. Code wasn't ready?

There are active peers and known peers. If your client runs long enough, you will see EVERYONE forging as an known peer.


So does this mean that some who are listed in the known peer list on a particular desktop client are actually active peers, and the given desktop client hasn't figured that out yet?  Just how long does it take for a desktop client to sync up and see all of these new VPSs out there on the cloud?

Not sure, it's in the software code somewhere, maybe there is even a limit. Plus I'm sure there a bunch of nodes behind NATs like people running on their home desktop, likely that 50M account.

NXT VPS Server Donations can be sent here: 6044921191674841550
At the end of each month I will donate some of them back to the community.
This is separate from my main wallet so you can keep track of them. I will keep them in there and only use them for hosting.

I really doubt that too! We are not too far of 1 Block/minute. So something doesnt compute here.

I guess it is like this now:

(Coins you forge with)/(total coins forging) = % change of creating the next block

The client seems to eat more and more memory over time. Anyone else noticed that?

same here, i have to write a small script to restart nxt after it crash

yeah, something's got to be done about this.
Although RAM is cheap and getting cheaper, some leaking is going on for sure  Undecided
it's not a problem for home users who just launch, make some payments and close, but for public nodes it is an issue.

I never saw Java memory issues with my node, and it served several tens of GB of traffic (public static IP; hallmarked). It did get stuck on some occasions (running and serving requests, but not on the latest block even after browser refresh), and a restart usually fixed that, although sometimes it required reverting to a backup blockchain.

I'd like to look at any Java memory issues you see. If you consistently see out of memory exceptions, please run the client with the following parameters:

 -verbose:gc -Xloggc:gc.log -XX:+PrintGCDateStamps -XX:+PrintGCDetails

And then share the resulting gc.log file. NB: this gets overwritten on start, so take a copy first.

You can also run it with this parameter:

 -XX:+HeapDumpOnOutOfMemoryError

This will produce a large file which is basically a copy of the entire heap at the point, so it's best to do it on a node with moderate memory settings (e.g. 512MB, not 4GB) and make sure you have sufficient disk space. Zip/gzip this up and upload it somewhere (e.g. mega) and share details. NB: very important, if you do this DO NOT enter your secret key on that node as it is likely to be visible in the heap dump (hallmarks are okay).

but how would that work?
We are nearly at 1/minute, with your formula that means that nearly all 1 billion coins are forging? Thats 100% not the case

The software keeps the passphrase in memory? That would be a bad idea.

Transparent Mining is an advanced feature and won't be included into released source code. It's the most powerful feature of Nxt atm.

All but sooner or later mixing is essential.
Any ideas whether zerocoin is applicable with NXT?

I want opinions before I ask the professor and his team - I think they may match idealy...

this is so frustrating, getting good alias only to have them not take

getting a transaction id then nothing

very very flaky

Don't know if you tried it, but increasing the deadline time to like 6-8 helped me. i had the same issues at first, for the record i had one alias confirmed for awhile and then taken away, given to someone else on the "right" chain (back when the chain was screwy and forked) so the system isn't solid but is probably better than before.

*edit
another thing. don't know how much it's been discussed, but unless you're picking an alias that is in DEMAND.. I don't believe there's any reason to pick anything higher than 1 fee.. before realizing that it would just take my highest offer, rather than, THEE highest offer, I lost a bit of NXT this way.. disappointed because the video by the user NXT (developer?) on youtube didn't accurately describe the fee process with Alias.


If you've had an alias nabbed: it's always possible for a bot to listen to the network for new alias request messages, and quickly submit a new one for the same alias and +1 fee, on the basis that if it's requested by one person it might be valuable one day, and so worth a (probably 2nxt) punt. Doubt anyone would bother now though.

By mixing you mean making a transaction anonymous? Then yes, that would be a top-priority for me.

The Nxt faucet has given away 2,472 nxt so far to over 1,000 people. Wow, that went fast! More still available.

Source code will be released later today!

In continuation of the announcement that we r looking for more Nxt core devs, there are features we r planning to implement till block 525960 (in alphabetical order):

- Alias System (done) - similar to DNS
- Arbitrary Messages (partially) - any soft can send messages in custom format
- Asset Exchange (done) - currency/stock exchange
- Distributed Computing (concept not ready) - similar to BOINC
- Distributed Storage - similar to Torrent
- Instant Transactions (requires peer review) - transactions with guaranteed confirmation
- Mixing Service (concept not ready) - laundering service
- Multisignatures - multisignatures Smiley
- Service Providers - off-chain services
- Shrinking - shrinking of bloated blockchain
- Smart Contracts (concept not ready) - http://en.wikipedia.org/wiki/Smart_contract
- Transparent Mining (partially) - can't describe in few words
- Two-phase Payments - payments with extra confirmation
- Voting System - good old democracy

I'd like to get ur opinions what features should be implemented in the 1st place.

Could we get, or is there a location for descriptions for each of what these do?
