NXT :: descendant of Bitcoin - Updated Information

[hoax]

Started another node with Hallmark on 37.139.12.71, with best wishes to Nxt

Well, I guess you have valid points, but at this time since the blockchain is small, that'll do I guess.
Or maybe it's really best to copy the files.
Let's ask CfB

It's better to copy files. Imagine what will happen if everyone deletes the blockchain simultaneously.

Working on node infrastructure with a full redesign of nxtbase to support 100+.

I'm going to add trusted peers list next to well-known peers. U'll be able to create a mini-cluster that shares all the data. Need to think how to implement it in the best way though.

Ok, I'll update the guide.
So copying the .bak versions is the proper way?

different than other coins which you can mine from scratch

In another words wasting kWh and amortizing you chips (CPU, GPU or even using special types of chips built for one single purpose...) = paying eq. amount of money (which always eq. to human-hours with a few remarks).

Block feeding chunks increased from 128 KiB to 1 MiB

What does this mean exactly, in terms of what it does for the network?

It means that when a feeder gets a request to get new blocks it sends 8 times more blocks at once.

wellKnownPeers is getting a little crowded with 30 names! I'm interested in this cluster idea.

No. U must copy *.nxt files. Use *.bak only if *.nxt corrupted.

Ok, I am just trying to set up a simple guide for users who can't operate in linux at all, so too many options would look too complicated.


One observation.
I downloaded a fresh version of NXT to my home PC, installed with default settings, blockchain synced from 0, all good.

But Active peers tab shows only 14 nodes. Is that not too low? Is the reason - the hallmark protection?

CfB has mentioned that if one gets access to the memory of Java Virtual Machine then your passphrase would be exposed.

That makes forging a *very* risky endeavor!

Wouldn't a big stakeholder have to have the biggest balls in the world to forge?  Everyone knows their IP.  Does everyone know their account number (and balance) if they're forging?  If so, they're a massive target with a huge reward.

To me, this seems key. Has it been addressed?

Putting aside the current client implementation, is it theoretically possible within the API for a node to have enough information to forge/sign a block, but not enough to do anything with the contents of the account (e.g. transfer funds to another account)?

The reason is low value of maxNumberOfConnectedPublicPeers. It was 20, I set it to 10 in 0.4.4. U can see 14 active peers if 4 of them were with red flags at some moment.

had some problems with my node, should be back fine now

0.4.4 seems to solve my problems!

Ok, clear now.

In future it will be possible to "freeze" an account using multi-sig feature. U can forge but can't do transactions.

Yeah, CfB delivers! We get new features and settings as promised!

Actually, I think it's coz we added more nodes.

[PGPpfKkx]

im a bit paranoid about security. i have 7874 open from the router does this pose any risk?

can in any way my coins be stolen while forging cause i have a pc forging 24/7?

is there any downside of not opening this port? blocks seem to download normally with closed

Looks like we dodged a bullet there. This was like a stresstest and we beat it =)

Gj us all!

+1. I'm liking a lot how the community rallied back from the attack stronger than ever.

When using the API, what's the difference between balance and effectiveBalance?

My effectiveBalance still shows 0 even though have over 3000 coins in my balance and the associated transactions have around 400 confirms. This is what I'm seeing exactly:

{"balance":325200,"effectiveBalance":0,"unconfirmedBalance":325200}
