NXT :: descendant of Bitcoin - Updated Information

[opticalcarrier]

i did a video interview with tai zen about how the network discovers the right chain. i cant make any promises but it may be helpful. http://www.youtube.com/watch?v=ZzKyXzZJJA8

dude, the longer you dont author our white paper, the more we will suspect you are BCNext.

I don't understand why it keeps happening to your node, but again those two block ids are from the correct blockchain - at least on the nodes I run.

I am still not sure, who determines what is the correct chain?

Anon, I think I'm sure I am not on forked chain. Check http://217.17.88.5:7874/

with base targets like those i would tend to agree. i do not think you are on a fork.

OK. So what is the problem? In public node i see errors for not accepting 90% of good blocks, which are good in blockchain, private node and public node.

Nxt is mentioned here - http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2393940 (It Will Cost You Nothing to 'Kill' a Proof-of-Stake Crypto-Currency)

Resume of this paper: All PoS coins will die except Nxt coz it's 90% attack-proof.

A system has already been created to reward running a public node.  https://www.peerexplorer.com/ (seems to be down right now for maintenance).

Sponsors create caches in the form of small amounts of NXT which are rewarded to registered public nodes.

Hmmm....must have been asleep at my desk when this happened. or it could have got lost in the information tsunami that is this thread.....

...or another thread:
https://nextcoin.org/index.php/topic,2266.120.html

Obviously I need to get out more......pity the cache system seems to have got gamed/broken.

LOL, probably lost in the tsunami

Looking at the nextcoin.org post, seems he's shutting it down after some recent changes let someone walk away with 4100 NXT...  A real pity.  The peerexplorer.com cache system encouraged me to set up a few extra public VPS nodes.  Hope he reconsiders...

Thinking generally here: we've put a lot of effort into clients, AM, AE, marketing, etc over the last few weeks, but network infrastructure has been put a little to one side, since the massive efforts we made in December/January to get the current infrastructure up and running smoothly.

Looking at the peer explorer :
https://www.peerexplorer.com/
I'm only seeing 399 active nodes right now. One of them is mine, so I am currently responsible for 0.25% of NXTs network.
 Hmmmm......I would feel happier if we had more nodes. 1000 seems like a nice number.

So, what do u guys think? Do we need more nodes ?
How can we encourage more people to run nodes, given that forging revenues are not exactly brilliant right now?

So, I'm really interested in this as I hope to get on the infrastructure committee.  Is Blockexplorer your site?  does it show ALL active nodes at a given time, or just SOME active nodes, or just systems that people have registered that may or may not be on at all right now?  These are basic questions, sorry, but gotta start somewhere learning to get ready to ask the harder questions...

holy crap this is nuts.. utilities actually breaking into houses to install smart meters? wtf?

I think it's wise to listen to this and consider some of the problems of proof of stake they're discussing:

Just listen to the whole interview because it's a plethora of good info.

CfB,

I am trying to come up with something that a forging node can do that a non-forging node cannot do. The only thing I have found so far is the numberOfUnlockedAccounts > 0 test, but this can easily be spoofed for someone that wants to pretend to be forging. I am hoping there is something that already exists in the NXT core that would enable a third party to verify that a reporting node was in fact forging. Maybe some sort of encryption calculation that is not done when not forging? It doesn't have to be 100% perfect for now.

I am just trying to make nodecoin that rewards people for forging. I dont want to use NXT transaction to do it, because it is too expensive, so I was just going to use direct connection to coin server. I was hoping that getState's cumulative difficulty wasnt available for non-forging nodes. Then I could just send that in and the coin server could verify it.

do you need nrs open in order to use solaris??

There is no way to determine if a node forging or not.

Which brings me to some important questions about where are we heading with charity marketing:
Is SoL going to be the "official" NXT charity?
Are we going to make an ongoing commitment to them, or move on to another good cause after we hit the target?
Are multiple charity projects a good idea?
Does any one have any suggestions for another charity to support?

We have two inquiries:

- Ra'ad Charity: https://asktom.cf/index.php?topic=468258.msg5179240#msg5179240
- SPICES: http://spices.org.my (they emailed me)

Please discuss!

Forgive me for having a little too much joy hearing this politically correct answer/reply from BitonicNL on twitter when asked whether they are going to start selling NXT for Euros! I have been buying bitcoins regularly from this site and is a happy customer.

Okay, let me ask you some questions. I put these ones on the table some time ago in my analysis of 'Transparent Forging' and CfB haven't answered it, yet. So, maybe you can.

You said: "The higher the stake involved in forging a block the 'better' the block."

So, how should a node (not the network as every node decides on their own) decide when two blocks are forged: one from account A and one from account B.

Now, there are several cases:
1) A comes first, TF says A is before B => A is on top of chain, B gets rejected when arriving (and vice versa)
2) B comes first, TF says A is before B => A didn't forge => B is on top of chain (and vice versa)

3) 2) happend; A arrived late; what happens? Will B get popped off?

It would be awesome to get some Nxt Coins for testing. My ID would be 2221954241417961541.

Thank you very much!

Wow!
This would be great!
Bitonic is very good and dependable :-)

[martismartis]

Returning back to my public node errors, I see, that my public node is in known peers list, not in active peers. Also in this list my node has version ?(?)@? Maybe from here comes problems?

Chuckone, in which list do you see your node and what version is showing near it?

[iruu]

Nxt is mentioned here - http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2393940 (It Will Cost You Nothing to 'Kill' a Proof-of-Stake Crypto-Currency)

Resume of this paper: All PoS coins will die except Nxt coz it's 90% attack-proof.

It doesn't matter how many coins are needed for destruction in his model, even 99.9% attack-proof currency would fall.  
It doesn't matter for NXT and other PoS currencies, because it's a ridiculous model.  

Short summary:
Each unit has a known, true value.  
Holders are willing to sell their coins at higher price than their real value.
An attacker has enough money to buy enough coins (using "true" valuation) to destroy the currency.  
Because he can do it, everyone sells his coins for nothing, because if he does buy the coins, anyone left holding will lose money. This causes the price to go to zero.
Therefore, it costs nothing to destroy any PoS currency.  

pure genius. let's sell nxt, everyone.

Which lists? I cannot see myself in the NRS. But I run 0.7.5.
