pls could anyone provide a basic info about client "Nxs" Like 3 sentences about it, maybe even 2 pictures.

Salsa,

There's some good descriptive text you can grab from their github page:

https://github.com/Regulus343/Nxs

EDIT: and like instacash mentioned, it's not a new client, just a facelift for the current default web interface.

We have a Wesleyh his client to cover that and function as the new webinterface when NRS is gone

So community, what do you think now? Smiley

Nice document. You could however add some Offspring screenshots from here https://bitbucket.org/incentivetoken/offspring-public/wiki/Home.

Bitcoin depends on a small network of mining nodes who support their operations by generating a fixed profit of 3600 bitcoins per day.  The available daily operating budget to keep Bitcoin from freezing up is thus $3.6M or less (at $1K/BTC or under) to  generate the current 25 million GHash/s needed daily.  A representative miner “pickaxe” is a Butterfly Labs Monarch costing $2000 and using 350W of power to produce 600 GHash/sec. Thus the current Bitcoin mining network has sunk unit infrastructure costs of at least $83 million and (at $0.10/KwH) ongoing electricity costs of at least $35,000 per day.  

Both costs are rising faster and faster. Exponential growth of Bitcoin’s hashrate (see blockchain.info/charts/hashrate) means mining rigs and energy use will skyrocket out of control, sooner rather than later.  Bitcoin, and clones like Doge, are thus by their very nature destined to fail.

NXT is the sustainable solution to this problem.  By using cooperative transparent forging, not competitive gigahash mining, NXT does not have an exponential forcing function at its core that drives its costs and energy consumption ever higher.  A NXT blockchain support network of 1000 Odroid U3 nodes has a one-time unit infrastructure cost of only $60 thousand and uses only $48 per day in electricity – forever.  
 

You could maybe include that every NXT is a virtual mining machine with zero power consumption. I think this is a nice 'picture' to grasp.

Sorry to say, if you cut away the smoke and mirrors NXT is not a way to make money by mining or forging.  NXT makes mining obsolete by making the required infrastructure so cheap that it's going to happen as a low -cost NXT community effort just because we want it to happen.

Here's some words I'm writing for distribution in Texas:

NXT Is Green

Ecological?  Financial?  BOTH !!!

Bitcoin depends on a small network of mining nodes fighting for their share of a fixed profit pool of 3600 bitcoins per day.  The only thing keeping Bitcoin from freezing up is $3.6M or so (at $1K/BTC or under) inflation per day, funding miner generation of the current 25 million GHash/s needed daily.  A representative miner “pickaxe” is a Butterfly Labs Monarch costing $2000 and using 350W of power to produce 600 GHash/sec. Thus the current Bitcoin mining network has sunk unit infrastructure costs of at least $83 million and (at $0.10/KwH) ongoing electricity costs of at least $35,000 per day.  

Both costs are rising faster and faster. Exponential growth of Bitcoin’s hashrate (see blockchain.info/charts/hashrate) means mining rigs and energy use will skyrocket out of control, sooner rather than later.  Bitcoin, and clones like Doge, are thus by their very nature destined to fail.

NXT is the sustainable solution to this problem.  By using cooperative transparent forging, not competitive gigahash mining, NXT does not have an exponential forcing function at its core that drives its costs and energy consumption ever higher.  A NXT blockchain support network of 1000 ($60 ea., 10W) Odroid U3 nodes has a one-time unit infrastructure cost of only $60 thousand and uses only $48 per day in electricity – forever.  
 

Excellent – thanks. I read the forum posts everyday trying to improve my (still) very limited understanding and this is one of those stand out posts that produce that 'Ah ha' moment.

Thank you for your kind words.  I've edited mine to the version above and I am going to try to get 2000 people to read them on March 6 at the Texas Bitcoin Conference.  Hopefully that will generate 2000 ah-ha moments - and 2000 new NXT users.

Hey guys i need some help!

The reddit-tip-bot went opensource now and i need someone to check the code before i release the Bounty to the dev. Can someone please do this?

Please please Smiley

Quote


The source code resides in https://github.com/nxtip/nxtip and is GPLv2 licensed!

The bot is based on ALTCoinTip, with some extra files that emulate the bitcoind daemon behavior as far as ALTCoinTip is concerned, plus handle the deposits. See the src/ctb/nxtip* files.

Contact me, there might be a bounty for the code checking!

Code:
for (w = 0, i = 0; i < 32; i++)
w |= v[i] = tmp1[i];

Is my pascal version correct?

Code:
w:=0;
for i:=0 to 31 do
begin
  v[i]:= tmp1[i];
  w:=w OR v[i];
end;


What exactly is the "if (i==0) { i=0;}" supposed to do???


looks fine, but are you sure your Pascal compiler supports 0 as an array index?
(Can't remember if the starting index could be set ...)


Quote

that looks like a place for a "conditional" breakpoint for debugging ...  unless someone had wanted to adjust some timing in the loop Wink


Thanks for the review!

Yes, pascal arrays are 0-based. :-)


ok Smiley   apparently you have compiled it already.
I was just remembering that by default Pascal arrays are [1..n] but they can be set   [ 0 .. N ];
Once ported Pascal/C ... maybe it was Pascal to C and the arrays were used as 1..N. So then there was two different ways to be chosen in C. Smiley


About OR :
I guess the Pascal compilers are still case-insensitive. And they haven't invented different operators to logical/bitwise OR  and to Boolean OR Smiley

I think you're right.  Hopefully the techdev fund will support programming and infrastructure fund will support deploying permanent hardware nodes like the Odroid U3  - which I have been converted to from the Raspberry Pi as the low-cost solution for NXT.

In Pascal, characters in strings are 1 based, dynamic arrays are zero-bases and static arrays are based on whatever you defined them.

OK so as far as web browser javascript transaction generation and signing goes, does it matter where the end client sends their signed transaction to?  do they have to send it to a NRS process that has active forgers, or can they just send it to any NRS system with a synced blockchain?  Im asking because Im considering opening up API for all the 24 VPSs I manage on nxtcrypto.org and am also considering adding SSL certs for that domain into the Jetty for each server as well.
The node doesn't need to be forging. If you send a transaction to any node, it will broadcast it to others, and eventually a forging node will include it in a block.

good question, TBD I think.

but you are a tech guy for sure  Wink

edit: maybe one commitee would be a better solution?

According to Wiki TF decides the next forger dependent on the previous block. So, if there is a partition of the network N1 and N2, then the nodes in these two different partitions have different TF outputs.

So, there are two cases: (next blocks/accounts are C, C' (part of N1) and D (part of N2); TF1 and TF2 are the output of TF of N1 and N2 respectively)
1) TF1 says C; TF2 says D => branches will get longer as foreign blocks get rejected
2) TF1 says C; TF2 says C' => C will get accepted; C' will get rejected as N1 expects C => What does N2? I would say: penalize C', ignore C and move on on its branch.

Still don't see how this conflict can be resolved. I need some idea for that.

Nxt uses Bitcoin's consensus rule. How would Bitcoin resolve this conflict?

IIRC, each node analyzes the known graph and assumes the longest chain as the correct one.

The same in Nxt.

ok, ill pursue getting SSL running on those VPSs, and opening up API for allowedBotHosts to * and leave allowedUserHosts nulled out to prevent remote forging, unless someone can think of a reason to open that up as well

IIRC, each node analyzes the known graph and assumes the longest chain as the correct one.

The same in Nxt.

Anon136's video described it as the chain that had the most stake involved in forging the blocks was the 'correct' one, even though there may be a longer chain.   Huh

It's slang. "Longer chain" == "chain with the most stake involved".
