I do a simple calculation for you as following:

Say 10, 000 nodes in the network for Nxt, as you know there are about 10,000 accounts.

Say each node is a Pi, say each pi consumes 10Watts, so total 100kW, it's 2400 kWh, which is just $600 a day with $0.25 per kWh.

Say each node is a server with 500 Watts, that's 50 times of the above calculation, so it is about $30,000 a day.

So I predict a total power consumption is in the range of $600 ~ $30,000 a day, and most probably below $10000.

Wow, that's the most efficient system in the crypto currency world.


Edit: go on a simple calculation of the price for Nxt. Presently a day's tx fee is ~ 5000 Nxt, if it should cover the power consumption, that is, $600/5000 ~ $30,000/5000, so the Nxt price in the range $0.12 ~ $6.

Yeah, my pricing for Nxt is $0.12 ~ $6.

OT: That's what I call a white paper: http://kim.com/whitepaper.pdf  

If I look only at top 8, they started with 400 Millions, now they own 250 Millions. I am pretty sure at least half of them belong to the core developers. It is a good sign, because these people won't ruin Nxt

If I look at other 14 Stakeholders, they owned 350 Millions. Now they have 90-150 Millions! There were some big trades so I wasn't sure if it was a trade or only a transfer to the new account, but I am sure about max number!

If I look at all richest 23 stakeholders, it's: 750 Millions on 24 November 2013. And now: 345-450 Millions on 10 January 2014.

If I look at 23 richest original stakeholders, they owned 75% of all Nxt in the first day, but now they own only 34-45%. 300-400 Millions had already been sold to the new users in 6 weeks.

The power costs should be negligible, because even on the machines that are running NXT, only a miniscule fraction of CPU time is needed for NXT. I'd estimate less than 5W on average per "client" node and less than 20W per hallmarked public VPS node for energy. Other stuff is even more negligible, like the opportunity cost of not having as much RAM available with NXT running.

If every node provider using a VPS stated their monthly hosting costs, that would be a number with some significance. Maybe also the network load figures.

That would be very difficult to calculate I think. Most nodes we setup in this thread are virtual servers, some are RaspberryPi's etc. You could maybe approximate with how any NXT accounts have been created but you still wouldn't know how many are running open at any given time.

Edit: I would still be curious to see even ballpark numbers.

If you guys need, I would be happy to proofread and correct any grammatical/spelling errors along the way. I already registered under my current name.

I just went through all of BCNext's posts and cherry picked the ones that seemed to be whitepaperish, or just plain interesting. Did you know about the NXT banknotes?

Hey guys,

I'm currently generating me a 777****777 address. Is my calculation correct that it takes about 900,000 generated addresses to obtain one in my wanted format with 6 wanted digits characters (the 1st digit can't be a zero).

The script is running on my PC and on my university cluster which isn't much faster. It's unfortunately running with the NXT API and in python. So it's not the fastest. I would like to make a native C version.

For this I would have to work me into the algorithms. Is this something the community wants?

Apparently, he took the money out because some people already sent him NXT.

In the app that I develop, you will expect to find resources at your finger tips.
No longer will you need to save multiple websites or fall behind the latest news about NXT. 
You will have access to ALL RESOURCES about NXT in one app.. and real-time updates with News and Social Posts.

Currently, my apps reach 15,000+ Active users... and that number is growing tremendously each and every day.
I plan to release a mobile application so NXT users receive real-time reddit/forum posts directly in the app. 

Here is a listing of all my current apps on the market place:  https://play.google.com/store/apps/developer?id=CIS+Solutions
I am expected to release an additional 5 new crypto currency support by the end of January 2014.

Here is an example of my latest project (pre-launch to the Quark Community)
https://play.google.com/store/apps/details?id=quarkcoin.qrk.crypto.com
- After launching the app, we noticed a 50% growth.
- In addition, we generated more investor interest and mining users.
- Traffic already exists for us due to our average rating reviews of 4.5+ Stars across all apps.
- I will streamline NXT through Social Media networks, and my traffic resources that add up to 100,000 impressions/month.
