Okay, I see. This was not what I meant. I meant, could it be possible to force popping off blocks containing alias transactions and therefore causing a rescan over and over again?
No, to force a block pop-off you need to have a better block / longer chain, etc. This cannot be faked, and if a peer lies about its cumulative difficulty and causes a rescan because of that, it gets blacklisted, for 5 min by default. And when one day we keep more stuff in database instead of in memory, the need for rescans will also be reduced.


So, theoretically, if I would buy thousands of nodes, I could keep everybody busy by rescanning the blockchain?

I have tested my raspi with a bruteforce script witch is checking account balances.

The raspi was able to answere ~400 requests per secound (web.xml ddos entry 30000). I don't know if this is an indicator of the resources of a raspi to get 1000tps done. The java process was consuming 95% CPU and the connection was 100Mbit.
Powerconsumption was ~3,5Watt (model B)

For comparison my i5 windows pc was able to answere 15000 requests per secound with 1Gbit connection.

Greets,
eb

PS.: Do we have a script or something to test tps? Would be nice to have to decide what hardware we need for the nodes someday.

Well, don't wanna take the wind out of your sails, but that doesn't sound to me like they decided to add Nxt. To me that sounds like Nxt is under consideration among with other coins, but has good community support so thats a plus.

Mintpal is down for maintenance now - to add NXT???
Maybe we should keep an eye on them and keep voting as we made it to the top ...

Can someone send me links to any secure online Nxt wallets available?  Working with a couple exchanges to add Nxt and want to make it easy for their end users.  Thanks.

i think the best is https://wallet.nxtty.com:7875 with trusted SSL

On the topic of exchanges

Please show some reddit love over here as well:

http://www.reddit.com/r/CryptoMarkets/comments/1yd9dx/its_welcome_week_at_coinmkt_zero_fees_zero/

Another possibility to buy NXT with US dollars. They have jumped through all the crazy regulation hoops already here in the US.

I have already exchanged a couple of emails with them as well.

And on the topic of reddit: it would be great for some more technical people to look in once in a while.

We are getting more new users in there with questions we cannot always answer.

It's not as scary as it looks and would be much appreciated Smiley

I got the wallet working, but the official faucet kept giving me an error. I also probably didn't create a particularly strong password.

Any recommendations on what level of password strength/entropy are required for a sufficiently strong password?

I'm merely curious about NXT. I'd like to see what I could do with it. I actually know some Java but never really had any incentive to keep learning it.

well my password is on the level of AD!e1wdsa$T#%345rdsfjhtUYgFHY!!`1264514mGBndsffdawDSAdrtvju^3651$%$%$sd (not my real password btw...just an example) ...  Tongue

Hopefully that type of style of password is random and strong enough...I tried making it as random as possible...

Very well. I'll create a more secure password and do that.  Smiley

Just need to finish up on some work and I'll get right on it.

Maybe I should just disable debug logging by default, it only makes people think something is wrong. The intention was to make it easier to follow what is going on with the block and transaction processing, in the cases where something does go wrong.

These questions will disappear after they have familiarized themselves with nxt-core. It's a process. It takes time.

Another issue:

many folks have the fear that they are on a branch/fork.

If you could find a way to demonstrate otherwise in the nxt.log. That would be great. Something like that:

Code:
[date] INFO: ....
[date] INFO: ....
[date] INFO: Fork probability: 0.01%
[date] INFO: ....
[date] INFO: ....
[date] INFO: Fork probability: 0.1%
[date] INFO: ....
[date] INFO: Fork probability: 14.2% WARNING
[date] INFO: ....
[date] INFO: ....

But, I fear that would greatly increase overhead at least for Raspis.

@J-L: Keep the debug logging on, I like seeing whats going on......

@ChuckOne: I find that u can almost always spot a fork by the number of unconfirmed transactions. If it ever gets over 20 or so, in my experience u are always on the wrong leg of a fork...and I've been there a few times.
Maybe u could just use the number of unconfirmed tx as a forking probabilty indicator ?

Can someone explain me how to get rid of the local time issues (I'm on 0.7.6, but this happened also with previous versions)? For instance, I get the following message in the console:

[2014-02-19 19:47:27.452] DEBUG: Will pop block 8909105522996058296 at height 70422

and then in the NRS client I see this as an orphaned block with time 20:47:11 (i.e., one hour ahead of my true local time, which was really 19:47). My system clock is synchronized with NTP (Brasil/East), I'm using Mageia linux (version 3).

A passphrase of 12 unrelated and randomly choosen words is the best, I think the Diceware method should be the standard recommendation for newbies: http://world.std.com/~reinhold/diceware.html

That or use Keepass

At this writing, NXT costs under 0.1 satoshi each.

should be "under 10000 satoshi", right?

And you could mention the "solved" 51%-attack-problem, by POS-coins in general and especially with NXT and TF

Thank you.  I confused mBTC and satoshi.  And good point about 51% attack, that is definitely another meme to put in there.
I'm currently doing the automated multisig gateways, so not sure if I have time to get the "push button" coin creator by the time of Texas conference. Just change it to future tense and we should be good.

Also, I think I figured out all the things that need to be done for a proof of concept automated multisig gateway. It has to be 3 community gateways and 2 of 3 multisig since that is all bitcoind supports for now.

Still, I should be able to rapidly add support for all the altcoind's that are bitcoind forks. Then all cryptos will be able to be traded within NXT AE. Deposit and withdrawal to bitcoin/altcoin addresses automatic and multisig. You will therefore be able to go from any supported crypto to NXT to any supported crypto.

Automatically!

This is a limited trust solution, as the three gateways are peer reviewing each other. As long as we figure out how to have proper failsafe methods for gateway private key recovery in case two of them disappear at once, it will be safe in all but the scenario where all three gateways collude. After the initial release, we would probably want the three gateways to keep one third each of the reserve deposits in an offline wallet. Then again two of the gateways would need to be hacked before any unauthorized withdrawals could be made. My concern is that there is no way to detect that one of them was hacked.

James

P.S. At first I am just going to release support for dogecoin, that way any losses would be easily absorbable

set your system to UTC then NTP sync with UTC, then change any DST/TZ settings to correct the clock.  Just dont manually adjust the clock to correct for DST/TZ.

Barring that, not sure what issues you are having
