NXT :: descendant of Bitcoin - Updated Information

 Also, would be great to have a "setting up hallmarked node" section in the wiki, can't seem to find it.

It should be somewhere in the wiki. At least I recall translating it a few days ago.

Found it, thanks.

@ AE client devs:

Do u need more APIs? Tomorrow I'm going to download a lot of new code into my brain so I won't be able to pay attention to other things. Post if u need anything urgently.

For the record: I havn't even looked into AE.

[msin]

Haha, Pin, good one.

Release 0.7.0e - experimental

Change log:

This is the first release using an embedded java database (H2) to store
the blockchain, instead of serialized java object files. Because this is
a major change, this version is to be considered experimental.

The blocks.nxt and transactions.nxt and .bak files are no longer used.
Furthermore, they will not be loaded at startup, when you start with
empty database the very first time it will need to download the full
blockchain from the network.

The database is stored under the nxt_db directory, as of now it will
take around 100 MB when downloaded. If anything goes wrong and you need
to start fresh, it is safe to delete that nxt_db directory, it will be
recreated.

There are no changes in the web.xml file compared to 0.6.1. I will add
parameters to tweak database settings later, if needed.

The database will use 50% of the memory available to java for its cache.
The actual value is printed out at startup.

Currently only blocks and transactions are stored in database tables,
everything else such as accounts, aliases, assets, orders, messages,
is loaded at startup and then kept in memory. The amount of memory
those take is still small, relative to what was needed for all blocks
and transactions.

At startup, the blockchain scan takes a bit longer, this is normal.
If anything else is unusually slow, I will look into profiling and
optimizing it.

There are no new user-visible features compared to 0.6.1, the code is
kept in sync now (including the critical bugfixes). Having both 0.6.1
and 0.7.0e nodes on the network should not result in forks. I will
maintain both the 0.6.x and 0.7.x branches for some time, until all
major database related issues are discovered and fixed. Please report
bugs, including the stack traces.

So when I do my installer for 0.7, is it going to cause any issues if I include the nxt_db folder as I include blocks.nxt and transactions.nxt now?

Which elements will be implemented in NRS 1.0? Any roadmap?

Why do we need roadmap in NRS? Is it BCnext plan 4?

[NxtChoice]

You're killing me!!!

Are you kidding? Is 0.8.0e coming today?

decentralized roadmap... definitely a feature which noone else can claim! Maybe we should vote on this?

How can I backup it?

No, but 0.5.12 was today as well.

Ok... I install new client... download whole blockchain... terminate client... client crashes after scanning blockchain upon restart... happened 5-6 times today... with three different versions. 

It doesn't make sense to have to download the whole blockchain almost after each termination of NRS.     

You're not supposed to redownload the blockchain each time

It's a very bad idea...

it looks like ltbcoin and the gameshow are public knowledge now. so i guess that means im finally able to tell you guys that i reserved the first 3 episodes of that gameshow to have nxt as the prizes.

I'm baffled shocked we are still talking about some rendered pictures.

In 3 months there will be 2014 IIHF World Championship right near my house (1 block away). I'd like to have some cool-looking pictures in case if I decide to give-away chocolate candies packaged in such hexagon boxes or other crazy stuff.

CfB is a hockey fan too    ....got my 1st hockey stick when I was 9 years old.

Point taken, I hope u won't do it too often.

[BitcoinForumator]

AHAHAHAH. Best one! 

[opticalcarrier]

can we expect to be able to zip up the nxt_db file to be used on VPSs when turning up new nodes?  Or in migrating from 0.7.0e to 0.7.1?

Also, I normally back up my blockchain with my client running. i just check current block, then zip up the 2 .nxt files then check to make sure the same block is still current.  Will this still be possible with the new nxt_db?
