Ah thank you ! I was asking for help from devs but no one is moving. If bit777 add Nxt this will be the biggest promotion ever. With what exactly can we help? what do you need? Pin Just helping him understand how the client work and how to implement it to his casino (considering the high traffic/transactions). The Nxt client is very different from BitcoinQt. This is a main problem we see also appear with exchange, people dont know how to implement it in they environment. Can we have somebody other than core DEVs JL and CfB to help people with this? who is willing to do this? Pin repost: This is a main problem we see also appear with exchange, people don’t know how to implement it in they environment. Can we have somebody other than core DEVs JL and CfB to help people with this? Do we have someone other than core devs that could explain how NXT works and help them setup business; this is also in the interest of NXT wesleyh? |

CfB, I have a lot of experience with SVM predictors. Basically given training data and answer, it can produce pretty accurate predictions. Overfitting can be controlled by special constant, so the smallest factor that gives acceptable prediction result is usually a good compromise. Unlike NN that take forever to train when there are a lot of inputs, the SVM can handle almost arbitrarily large feature set. Millions of features can be used. Prediction is a simple dotproduct of feature vector with linear model. I think here is finally a technical part of NXT I can really contribute to! Just need to develop a set of features and zombie/not-zombie categorization for each set of features. James Great. Post in that thread, plz. Can't. Login didn't work. Asked to reset password, still waiting on email. Any chance of having thread on nxtcrypto? James |

Someone asked me about Cryptsy. They did contact me a hour ago. I already sent all info they asked for.
Good news is good!  Oops, sorry. I've just checked. That was Vircurex, not Cryptsy. Would wesleyh's glue code be of use to them? James |

Some thoughts on fees.
I had earlier posted some thoughts on making fees different depending on the size of the amount transferred, but now have different thoughs, since we also have to include aliases and AM and other transaction types.
Im putting some items together, but can someone please break down the blockchain and blocks vs transactions for me?
Is my assumption correct that every block is always the same size? Or perhaps the size can vary but zeros are prepended to make all blocks the same size?
Im thinking size may vary since you can have losts of transactions per block. but where can I go to get this info?
Edit: OK I see that size of a block can vary....
OK what are the max number of transactions per block? Is this fixed or are there ideas for changing it in the future? Whats the max size of a transaction?
I believe 32K, which can hold 255 transactions, much fewer AM. Cost of AM at 1 NXT seems to be a bargain considering the space in the blockchain it uses. If we say each block is worth 255NXT for 255 transactions or around 30NXT for AM, that makes AM almost 10 times cheaper. I strongly suggest AM cost of 0.01 is a disaster. It is long term storage in blockchain, distrubuted, redundant, etc. James |

It seems "Arbitrary Messages" has gotten a lot of people thinking that its purpose is for messaging. Wouldn't the name "Arbitrary Storage" be more appropriate for what it does?
Arbitrary Storage would be confused with Alias System if u used abbreviations. Arbitrary Data |

CfB Can you confirm that all Arbitrary Messages (Storage) in the blockchain are encrypted |

CfB

Since it is not stored in the blockchain in plaintext, I think the problems about illegal content are minimized. Only receiver can decode it.
Lowering fee opens up NXT blockchain to spam attack. Cost of a few cents to store 1K of data for 1 year (or permanently?) seems to be a pretty low price already

64-bit encryption is only used for accounts that have no public key and haven't done any transactions. It is recommended to make public key and do at least one transaction. Send someone some NXT, buy an alias, basically I think any proactive usage of the account gives 256 bit protection
How do I make public key? pay at least 1 NXT fee for any kind of transaction Or forge a block. Does one need to back up anything after that? Will the password on a fresh install/device still bring up the account? The password is the account. As long as you have it, you have access to the account |

The use of 64 bit encryption anywhere is a FATAL FLAW that prevents anyone from taking NXT seriously. FIX IT!   Is that a sign of disagreement or lulz for me being nervous sitting on my non-future-proof NXT? 64-bit encryption is only used for accounts that have no public key and haven't done any transactions. It is recommended to make public key and do at least one transaction. Send someone some NXT, buy an alias, basically I think any proactive usage of the account gives 256 bit protection |

Good. We'll get some bitcoins to set a reward for Nxt crypto algo audit. Yes, bitcoins, not nxts, coz if the algo is flawed nxts won't be worth a lot  . @CfB, have the developers considered switching to Ed25519 instead? I think it could easily be deployed (i.e, require all txes + blocks > 40k block to have new sig). There are many advantages. First one being it's much better verified and tested than current sing+verify. Second one is probably speed (although I haven't tested), as computations in Edward's form should be easier. I am pretty sure BCNext decided to use current approach over Ed25519. Can't remember the exact reason, maybe it was to be able to run on cellphones? James |

For those who care, I think I finally figured out how emunie is supposed to work. Basically, as money comes in more emunies are created. The system is going to try to stabilize the price, so let's assume it is successful and it holds the price steady. Don't remind me that no government has ever been able to fight the market forces and hold a price steady.
To estimate your gain from investing in emunie, take the total amount of emunie money supply from when you purchase to when you sell. You get 50% of the change in money supply. So, if the initial distribution is for $1 million worth and another $5 million comes in, you will get 2.5 times your investment.
So, the more widely the initial emunie is distributed, the less will be gained by initial investors. I have not yet figured out anything about the hatching process or what sort of incubation equipment is needed, but it seems that the hatchers make as much money as the initial investors.
The biggest open questions are how exactly is the emunie money supply managed. Everything about emunie depends on this and it is kept tightly secret so no way of creating models or doing any sort of analysis. If it all magically works, I would be amazed. Not impossible, but still many unanswered questions.

Don't sell NXTs so cheap and in big amounts because you only help speculators kill Nxt rate on DGEX. Seriously, not when bitcoin is falling. This is the best way to damage community because noone will invest in it since rate can't recover. Even big stock holders aren't damaging it so much like you this way. I don't see any strategy here no HOLD action to help Nxt rate and create demand boosting community growth. When someone leaves dgex he want go back soon. Even if someone don't like dgex it will still affect price of Nxt on any other exchange in future. Kill it and u'll kill Nxt.

If community can break only because there's no "to da moon!" action... Do we really need such kind of "community"? We are at yuriygeorge's price point, at least on dgex. |

What is the right word? I am trying to balance technical accuracy with conveying the appropriate concept to the reader.
I think "fee dividend" is probably about the best one (it conveys the idea that you get something because of your investment without the idea that that something "comes from nothing"). Yes, that is pretty good. Also due to the variability each person gets a different rate, easier to understand the rate difference if it is a dividend (which is expected to vary) as opposed to interest (which is expected to be stable) |

Editing Wiki now. This will take some time. Also, we need to discuss the "interest" thing. I dont really like that, especally compared to bitcoin. Its not interest, its the same thing as bitcoin processing blocks for transaction fees. What do you all think?
Don't use the word "interest" that is what "fiat" uses and is *wrong* when it comes to a currency with a fixed supply. What is the right word? I am trying to balance technical accuracy with conveying the appropriate concept to the reader. "interest" "yield" "dividend" |

It is not the same at all! Financially, it works like interest since if you have NXT, you get more NXT. Maybe dividend is a better word? NXT has a built in dividend reinvestment program (DRIP). BTC has nothing like this, certainly it doesn't go to the owners of BTC. |

Question on ripple:
I managed to deposit some nxt, but now it seems that I have no access to them..
When I put in my RippleAddress it is asking for a secret key. What is that?? Did I create a secret key=? I have noticed a secret key previously, but when I put it in there and send on Sell, nothing happens. No message, no error, nothing. That is not really userfriendly..
If you are on a Mac, I think there are some problems with direct trade page. If you use the ripple wallet directly, you don't need to put any secret key anywhere, it is already in the ripple wallet. Just go to trade page in wallet, type in "NXT/XRP" uppercase in the dropdown. Input peercover's ripple address for issuer: ra9eZxMbJrUcgV8ui7aPc161FgrqWScQxV Now the orderbook will appear, current bid is 2.25 XRP and ask is 2.69 XRP, about 30% above dgex prices. Kind of a hassle, but worth doing to get a bit more from selling NXT |
