Can anyone tell me why I get nodecoin even though I'm not running the nodecoin script?
Because skyNXT is self aware and knows how important your work is to its ultimate domination.... Seriously James started out with an idea to reward people running nodes so that they did not just rely on forging. Nodecoin has been around a number of weeks as a result and valuable time has been spent on it... All I see in the thread is downside and negativity, ok nodecoin is not perfect, but its not cancer, and if it is - lets hear the alternative? Do we still need to reward people who run nodes? Are we waiting for BCNext or his 12 or is it 21 disciples and the super nodes they will deploy to forge on and earn all the transaction fees from everyone else's handwork? |

If there is ever a crisis and we need a lot more nodes, we just need to put a 1 NXT per nodecoin bid in AE (144,000 NXT per day!) and we will get new nodes like crazy. It gives us a way to very quickly add network resources. Also, in this event all the crazy nodecoin mooners will have their aurora dreams come true
James Actually seeing it like this, it is a very smart and novel way to have the network adapt dynamically. Awesome! Hopefully it works out as planned in practice. I have one problem with this - as the number of coins increases 'Node Coin Whales', basically as posted earlier and in a PM to james, I like the concept but a free floating currently can be gamed, and when we add 1NXT to get people to run more nodes, the whales will move in with their sell orders and we will end up being blackmailed.... If we can figure out how to avoid this so that when people 'earn node coins' they are not just subject to wild speculation I would be happier... My view of trying to make them time limited per month to control volume/speculation issues was just one approach - I'm sure someone has a better idea to address this risk? |

For the smart maths people out there This chart says http://www.engineeringtoolbox.com/volum-expansion-coefficients-solids-d_1894.html the volumetric thermal expansion coefficient of silver is 58.3 (10-6 m/(m K)) i can only assume they mean m^3 since that is how you would measure volume. So if i multiply 58.3*0.000001 i get 0.0000583 So silver expands at 0.0000583 meters cubed per meter cubed per kelvin. Room temperature is about 300 kelvin. The melting point of silver is about 1233 kelvin. So that's a difference of 933 kelvin. So then i just multiply 0.0000583*933 and get 0.0543939 meters cubed per meter cubed of change. Ive got to be honest that seems crazy. a 5.5% change in size as it cools? there is no way that can be right. Its written as a linear expansion coefficient e.g. (m/m K) not (m^3/(m K)), a linear coefficient which is change in length per meter and degree of temperature, volumetric is 3x linear for a solid, but another reference I have says the volumetric expansion coefficient for silver is 54 *10^-6 (m^3/(m K)) AT 20C - So I think it may be a volumetric expansion coefficient just worng units.... BUT I don't think solid to liquid volume change can be calculated using a constant - so your 5% may be wrong because you have a 'state change' EDIT: density of solid silver at room temperature = 10.49gcm^-3 density of liquid silver at melting point= 9.320gcm^-3 perhaps this is a simpler - the ratio of the densities will give you a volume change between liquid silver and room temperature solid silver. |

On Nodecoin/NXTcoin:
1) Who will buy them? It seems to me that it will follow the mine & dump path, so:
2) It will devalue NXT
PS: Ricky do you have skype? If yes PM me your ID please...
2 seems to contradict 1. IMO, the more active nodecoin is, the more valuable NXT is either people will run nodes as forging pools or we need people to run nodes and find a way to reward them... nodecoin can provide proof of the work someones node has done irrespective of how much NXT they have... let STOP thinking of it as another crypto currency but as a proof of a nodes work which needs rewarding with NXT this reflects the contribution of the node to the stability of the NXTwork? (whatever the collective noun is for a collection of NXT nodes) lets not think of it as a coin... so I'm going to call it something different - don't care what just want to ditch coin. suppose in january 2014 NXTWork PoW Demon or its equivalent generates NXTWork201401 and in february NXTWork201402 now suppose we have a bounty for operating nodes each month when january is complete ,we will know how much work the NXTwork has done in terms of NXTWork201401 tokens. we know the january bounty - divide the number of NXTWork201401 tokens their are, create one order for the total at a unit cost that spends the bounty and buys back all the issued tokens. everyone can redeem their NXTWork201401 for a share of the bounty... then delist the NXTwork201401 Repeat in 201402 Repeat.... If the bounty drops too low - people will stop running nodes.. if this affects the NXTWork, people who want to have a better NXTWork will increase the bounty and people will run nodes.... If it doesn't then the NXTWork bounty and the number of nodes will balance each other. A bit crazy perhaps but it does provide a natural elasticity to allow the community to drive the performance of the NXTWork (sorry couldn't stand typing NXT Network) |

Think of it this way: Buy running a node and supporting the Nxt network, you get social credits in the Nxt community because you are part of the support for Nxt. Hence node coins are only valuable within the Nxt community. When Nxt is rising in value (Nxt community getting bigger), your node coins are worth more because you support a bigger Nxt community which uses the Nxt network.
Obviously, the Nxt community sees value in many people supporting the network. Therefore node coin has a value.
Now use node coin as a tipping coin and Nxt is the king.
OK. But who will by nodecoin for NXT/BTC/other and why? Where to spend nodecoin in real world? that goes for every single other alt coin.. yet they have value.. nodecoin is an interesting experiment - a coin awarded based on the useful work an NRS node does... if this is useful in establishing stable nodes then we can look at how to give these value if this is good way of subsidising/encouraging the creation of the network. |

Hi guys, This is Nodecoin, that James has developed. We need to test it, but I have no idea how I should make it work on Windows: It is for testnet the following is how to get it compiled and running from command line git clone https://github.com/jl777/multigatewaycd multigateway chmod +x run.sh ./run.sh ./nodeminer <NXTacct> <passphrase> I cloned it to my drive, but what now? Any suggestions? You run it on the same machine as NRS and based on the work your NRS instance does it creates node coins under that account on AE. I'm running it on all 4 testnxt nodes - generating lots of node coins  |

**BUG I THINK If you log out and then log in with a different account you get buy/sell messages reflecting the different assets. So I logged out / in with different accounts and I get messages on log in like 'you bought 138 node coins' because the two accounts have different amounts and you bought 1440 Ranbow ends because one account has them and the other account doesn't have any. Looks like some residual data is surveying the logout. I tried to capture the messages with screen cap - you can just about make them out here. *EDIT: nothing is being bought and sold of course so the messages are in error.  Should be fixed, please test. Fixed |

On the todo list :-) thx
thanks, asset creation at 1000 nxt - does this need a summary screen and a do you really want to do this... I'm just imagining the screams of ' I spent 1000 nxt and made a typo and this client didn't stop me from doing it'... the asset equivalent of a short password screw up... In fact there are a few places for a confirmation screen... Could be a user switch - default 'on' - experienced trader can default this to 'off' Would make them just a quick summary of the action with a 'yes/no' - it might be worth thinking where and if to put these... EDIT: like the groups... is it possible to make them collapse to just the header i.e. save space when you are not using them? EDIT 2: can I suggest you make this type of pane scrollable - it would work really nice on the mac  |

Wes - can you add a filter field at the top of this list. So if I type 'BTC' then it only lists assets containing that string. would make it case insensitive... I think the asset list will get long quickly and this will let people find assets quicker  |

I've commented on the paper, its interesting, needs work, at this moment I think it has a number of flaws and assumptions which need correcting for any community funds to be spent wisely. |

can parallel chains be 1min blocks and 1s, 5s, or 10s out of sync so every 1s, 5s, or 10s one chain is forging?
Not sure. If the block time is 60s,.... what defines when in a minute the 60s starts and can this be adjusted per chain perhaps? Ian |

There is a display of nodecoins earned, paid out, etc. It would be nice if half a dozen testers could just run in in a console window. Need to make sure the client/server networking is stable.
James
Put it on all 4 testnxt nodes let me know if it causes a problem... |

Any suggestions about Parallel Chains? If not then I'll stick to BCNext's draft.
A question: can parallel chains be 1min blocks and 1s, 5s, or 10s out of sync so every 1s, 5s, or 10s one chain is forging? this might be an interesting answer to the latency problem of 1min and provide more opportunities for clients to get quick confirmation of transactions... |

Anyone for a pint?

That may be a possibility but for this we need other client developers to agree on the same standard and the same questions. We can't have all developers making their own implementation.
Thanks Wesley. That is a valid point. I would also point out as the wallet.dat just contains the brain wallet passphrase, as long as one client supports this method of generation and the wallet.dat is consistent you could generate it and move it - the point is a trade off between security and ability to recover. I think if you consider that no method is perfect then some kind of structured generation does not really reduce security much. If it is implemented and popular then others will copy anyway. Also a user hashing a passphrase built from structured information for 30s or a minute is going to make it harder for someone to crack aren't they? |

I think something like this could solve the passphrase problem,adapted to Nxt,keeping its essence of brain wallet,and no wallet.dat file.People could generate their passphrases with no need of knowing them in a super easy way,and would follow BCNext's first idea. http://braincontrol.me/http://betanomics.asia/blog/store-and-send-bitcoin-directly-from-your-brain-using-braincontrolBrainControl ultimately uses the following function to determenistically generate the necessary keys at the precise time required to perform any sensitive functionality such as send or backing-up: <script>
var keys = btc.keys(Crypto.SHA256(salt+url+Crypto.SHA256(username+password+pin)));
</script> Someone will need to explain this in a little more detail. Won't URL always be the same? (in case of a desktop client there's even no URL). Im not a programmer,but i guess URL could be excluded.This is just how this site works.I found it in a tweet from Antonopoulos, supporting this.What i think is useful is the idea. Just try it and take the idea.It will even show you the bitcoin private key the wallet generated if you want to save it somewhere. It could let people use 2 or 3 easy passwords,and a PIN,easy to remember,and create the NXT passphrase from there For example,putting account name : nxttrial passphrase: nxtsecondgeneration extra salt: nxt pin : 123456 This gives access to the publid bitcoin ID 1Ax7FXk9Q8oneRpkPv9GzMyi6gjf4y6Sg5 If you click backup, it gives you the QR code and the private key : 5KACFTu5aESZQ7THmSpgkFkew9J8EJRhSeuNWuBmEkcGhE28yGk So you are not saving it anywhere.It is only that in 5 years,you come back and put the same login details,it will give you access to she same account.I think this system could work for Nxt and be user friendly.I cant say how safe it is,but i guess it is. What's the difference between this and simply having the brain password: nxttrialnxtsecondgenerationnxt123456? Thats why im not a programmer,and maybe its just stupid,hahah. But at least it made you create a more than 30 characters long easy to remember passphrase with numbers and letters,and symbols could be mandatory. The idea is that nxttrialnxtsecondgenerationnxt123456 --> 5KACFTu5aESZQ7THmSpgkFkew9J8EJRhSeuNWuBmEkcGhE28yGk , which would be the Nxt passphrase,but maybe it is useless for security reasons Well, if this is the default method, a "hacker" would simply use the same encryption method on the brain password to get the "real" passphrase. Or am I wrong, anyone? Gulp - this is a dangerous place to tread but I think I should have a go... I was thinking along these lines when I saw this post.. Wesley - logically you are correct but from a user perspective putting in the information in a structured way would help the user to remember, and recover their passphrase. Other people are also right - we have a problem if this is lost if we don't have robust back up mechanisms. I would go even further.... Ask a series of questions - things it would be difficult for an attacker to know; e.g. What is your favourite place: barcelona What is your lucky number: 88 What religion are you: jedi What was your mothers middle name: leslie Please enter a memorable 4 digit pin: 1234 I would combine this into a phrase - hash it <lucky number>*<pin> times and save it as a passphrase in a wallet.dat which is password protected. Hashing it lots of times just makes it a bit more computationally expensive for a brute force attacker.... If the user loses their wallet.dat or forgets their password, they can regenerate the 'brain wallet passphrase by re-entering the structured information which should be memorable for them and they won't have to write down. Is it secure, its more secure than a sha256 password that no one can remember, its more secure than just a wallet.dat that can become lost of corrupted and its more secure than a short brainwallet password that people use so they don't have to write it down. You could have this option, the alternative to use a pure sha256 random pass or enter your own brain wallet password. |

Life has to go on, right? I died for about 1 minute but I think that was about it.  I am sorry what happened to you happened, we all have those moments sometimes where we ignore a warning and regret it later.. I would probably have died for longer than a minute... I agree refusing to accept a PW less than 20 chars would help, with this specific issue, but then hackers would create dictionaries of common 20 char words and phrases looking for someone who had tried to use a phrase they could remember. Unfortunately there will always people out there trying to take advantage of mistakes people make and in the FIAT world these crooks can be caught, in the crypto world the environment itself prevents that, ergo we need to try even harder to help people not make mistakes. Due to primitive client SW NXT exposed something to the end-user that other crypto's hide, I expect the emerging NXT clients will improve this generating/enforcing strong brain wallet passwords, whilst using a local memorable password and/or 2FA mechanism to allow access to this.

I agree his actions are beyond reckless, but HIS ACTIONS ARE KILLING NXT. When one guy loses 20% of his portfolio on NXT due to poor password security and tweets it out to *** 2100 *** followers, WE JUST LOST 2100 PEOPLE WHO WON'T TOUCH NXT NOW.
THIS IS A DISASTER.
WE COULD HAVE AVOIDED THIS DISASTER IF WE HAD IMPLEMENTED INTEGRATED AUTOMATIC STRONG PASSWORD GENERATION IN ALL CLIENTS A MONTH AGO.
ARE WE IN AGREEMENT TO IMPLEMENT IT ACROSS THE BOARD NOW?
I don't think its a disaster, its unfortunate, and when the 'official' client's are all out with a better solution, put up a page and tweet a url to it with the same tags. I agree we have to protect the unwary from having direct access to a brain wallet but we will always have this if people do not follow instructions, he doesn't say what client he uses... Was it NRS directly? Currently you get this when you click 'unlock' in NRS.... If opening a new account, please note:
A simple passphrase will certainly result in your NXT being stolen!
Do not use any phrase that appears in any printed or online material,
no matter how long or obscure. A secure passphrase will be at least
35 characters long and consist of random letters, numbers, and special
characters, or a meaningless combination of 10 random words.
And if you ignore that and type in a stupid password you get... Your secret phrase is too short
and can be easily picked by a hacker!
So that was TWO WARNINGS that he did something stupid, unless he used some other client and that means we have a downloadable client on our site that accepts bad practice without any warnings, or he got a client from somewhere else which means it could have a trojan in it anyway... We cannot protect the gullible from themselves and we cannot protect ourselves completely from the bad news that the gullible being taken advantage of will always generate... But I do agree we could/need-to be better at security than we are currently. |

Did mintpal refund people the money?
Demand your money back if you paid them for listing Nxt
Just for the record. I seem to have got mine back. |
