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.

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).

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)
- Arbitrary Messages (partially)
- Asset Exchange (done)
- Distributed Computing (concept not ready)
- Distributed Storage
- Instant Transactions (requires peer review)
- Mixing Service (concept not ready)
- Multisignatures
- Service Providers
- Shrinking
- Smart Contracts (concept not ready)
- Transparent Mining (partially)
- Two-phase Payments
- Voting System
- some non-revealed features

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

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.

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.

I like that

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!
