NXT :: descendant of Bitcoin - Updated Information

[l8orre]

Thanks! I am reluctant about the overclocking, but I run it with -856xmx ...

What does -856xmx do?

It is the memory available to the jvm, I quoted it wrong:

ps -ax
 2040 ?        SNl   61:45 /usr/bin/java -Xms128m -Xmx856m -jar start.jar STOP.PORT=7873 STOP.KEY=0815


-Xms128m is the minimum that is reserved at the start, and -Xmx856m is the maximum it can have, in megabytes. I often had crashes with a maximum smaller 450MB, but with giving it almost all the memory, it runs quite good.

Except that dl'ing the whole blockcahin is quite some venture.

i use -Xms320m -Xmx480m
how can you give it 856m? Don't you have a pi with 512MB? Or are you using swap? Or an other device?

I think I have model B with 1GB - I run it off a start script someone posted - don't remember if it was DaveTheTrousers or somebody else..
I can post it tomorrow, but basically it just gives the Xmx856m into the java start line.

Complexity of signing is O(1).

That is plain wrong. The more bits you have to sign the longer signing takes. The question is: how long in terms of the input length.

We would have O(n) if Sign(32_bytes) == Sign(64_bytes) / 2. Actually we have Sign(32_bytes) == Sign(3200_bytes) / 2, so it's more like O(1). Right?

Sorry, still wrong.

It looks more like O(log n) but don't think so, as the whole input has to be read. That still takes O(n).

If we count time to read the input then we should count header processing time too. What about a compromise at O(log log n)?

Well. No. It's like a mathematical proof.

E.g. if you want to XOR all byte of the input onto the same variable, you need O(n) because you are reading the input. As simple as that.

When making compromises, let's just assume Qubic is safe. I think it's rather 66% safe as instead of 51%, agreed? I mean 66% is even easier to remember.

Is this really so important? If we can Sign 100 times as many at once at twice the cost, it is 50 times more efficient. Regardless of exact math equation that describes how much it is faster by, it seems it is much faster with big number of signers and I dont think it is measurably any slower with 1 sig. So it is the same or a lot faster. Why the debate over this, it dominates (mathematically speaking)

1) It seems interesting.
2) 'it seems' is not 'it is'.
3) Examples aren't proofs. It could be easily vice versa when bigger numbers are involved.

du says: 257480 for current nxt_db folder

What? Mine is 111M only.

Err:

Code:

pi@raspberrypi ~/nxt $ du -h nxt_db/
252M	nxt_db/

Wrong usage of du?

Mine says 114M - still on 0.7.4
du -h

0.7.5

Code:

du -h nxt_db/

I am still too tired to think about it from the higher perspective. So just a little conclusion. We need to send 2-4 ambassadors to every Bitcoin conf/convention, it is really essential.

Fantastic recap, Salsa... thank you for your hard work!

We should always have someone close to these conventions, this will minimize the costs. Just making that ONE key contact is all that is needed to pay for these events.

Without attending this conference, we wouldnt be discussing building a country's currency on top of NXT. It has a giant advantage over paper money. It cant be counterfeited as long as the NXT network is secure! secondarily no costs for printing.

As soon as the first country, or village, builds a currency on top of NXT, all realworld items will be priced in NXT
I see the Asset Name space getting very crowded.

James

Salsa is exactly right, it takes 3 or 4 people to handle a conference the way we need it done.  The Miami event was 1500+ people, there was barely enough time to meet with all the major players let alone meeting with different crypto supporters. We made it happen, however, additional resources would have gotten us even further.

I'd also recommend reading Nikel's summaries, it's a great way to provide real time information back to the community to take action. It would be nice if we could put together some type of document outlining best practices.

For example, the best way to meet everyone in a circle is asking the primary to introduce you.  When I would talk to someone at the conference, I'd find out who they knew and ask for an introduction. Networking 101 goes a long way when you're surrounded by a crowd that might not be as familiar with how to control the flow at larger trade shows.

So now that we've been to a few of these, I'm curious...is getting a NXT booth or table a good idea, and letting THEM come to US?  Or is gentle non-stop mingling and shaking hands the way to go?

Hello James,

Sorry for my english, I can read but I don't write well. I'm not very active in the common community but in the french one.
I can't help for technical things but I have some ideas about sociology and eco-politics.

I read that and I am very interested :

I only dreamed about an entire country using crypto as their national currency. It sounds like many smaller countries are ready now!

I propose a bounty for a coin development kit. It needs to make creating a new coin push button easy. I am not sure even how it should be implemented, but it needs to be something that can be used as a replacement currency for an entire country. I guess QR codes on mobile apps to do payments would work for a realworld economy. The more customization options the better.

I will start the bounty with 25000 NXT. If you also like the coin development kit idea, please make a directed donation. just post txid and amount sent to NXTcommunityfund 13776816462073143763

This improvement could be great and I can help for the bountyfund but I want to know more about this project. I think, it's very important to integrate new concept in the cryptocoins on top of NXT. It's very important to seduce politics and institutions.

I think about Universal Dividend like this cryptocurrency project : http://project.openudc.org/
Other things are possible the possibility to have concepts like Devcoin (without mining).

Could you give me your idea for this bounty and his goal ?

Ludom

I downloaded the client and thought I would be able to forge a few coins but the forge link on the site doesn't work.

How does one go about forging some of these coins?

I think both would be best, having a booth occupied with someone and others go around introducing them self. We are not that popular yet just to be sitting in the booth and letting people to come to us.
Maybe, when we are able to pass $1 per nxt or 1000tps which ever is first. Only Then we could just sit there and people will be lining up to talk to us.

[CoinTropolis_JustaBitTime]

Team,

We have a major opportunity with the charity to be the official sponsor:

"We can bill it as Nxt presents…,

Check out who we have on the bill:

songsoflove.org/LA

We can change the bitcoin Logo to Nxt."

Not only would we gain press before the event (which would open doors to a number of different writers), we would get media exposure at the event. I need to work out the details this weekend, but yeah... I'm pumped.  If Dogecoin can raise $30k for a bobsled team, I see no reason we can't raise $10k+.  

Blu Cantrell will be there... guys, this is a huge event.'

** Large Stake Holders and Marketing Budget **

The amount of press and exposure we will get from this is an amazing ROI.  I'd love to see some of our bigger holders as well as looking at the marketing budget to help support this initiative.

I havent figured out how exactly to create a coin on top of NXT. It is supposed to be easy, so that is why I started bounty with 25000 NXT. My hope is that someone that knows how to do this (hint, hint) will publish a reference coin on top of NXT. Then we can extend it by adding customization, etc.

I am thinking that a new coin would simply be an Asset inside of NXT AE. So the community gateways should be able to provide a turnkey coin creation service. However I am not clear on how to enforce any sort of proof of work mining....

Oh, of course! I think I just saw how it could be done. Let it percolate for a bit in my head. I will disclose the method to any community gateway providers. Still need 3 more.

I think we can create a mechanism for anybody to issue a new "coin" that will trade within NXT AE. Any type of proof of work, proof of stake, proof of whatever, could be specified. Of course the more complicated it is, the more work it will be to implement, but somebody familiar with bitcoind should be able to create a PoW coin on top of NXT. Not that we want to encourage such things, but the beauty of NXT is that there is nobody that will prevent you from doing a PoW coin on top of it. As long as 1 billion coins is enough, NXT AE seems to be a pretty good platform for customized coins.

[lucky88888]

Eeeerm,

I issued a buy order for 1400 SkyNxt asset and somehow ended up being the owner of all of them?



Edit: look how smart I look in a suit in my avatar!

My mistake, I'll fix this!

Damn!  

K, do a hard refresh, and you should see your assets slinking to 1400 ;-)

Btw, fixed some other bugs too - and no longer allow anyone to log in without a password. (In the official client you can log in without a password but this serves no purpose so I completely forbid it).

Loading indicators sprinkled everywhere, nicer loading of asset listings.

Added more blogs to the news page;

nxter.org
nextcoin.org forums
nxtcoin.blogspot.com

aww i was playing around with the "null account"..
and are we somehow able to add a refresh button somewhere, instead of relogin everytime i want to see new assets or other things.

Change log:

Another bugfix in the transition to Transparent Forging, starting from
block 67000. Upgrade before this block, because there will be a fork.

This release drops support for the old getMilestoneBlockIds protocol.
Clients older than 0.7.3 will not be able to request blocks from 0.7.4

Some optimizations in the database queries used during unlock account,

Minor other improvements.
