So I've been following cryptocurrency for almost a year now.
I have been mulling over an idea and thought it was time to release it to see what people think.
I don't know how this could be done, and not sure if it could utilize nxt due to high TF.
Now that there has been discussion about making coins built on top of Nxt I can forget about the high TF for now.
The idea..
Tying digital image (or any file or digital content) ownership to a colored coin via smart properties (that's my current thinking on how to implement)
This would give anyone that wants to copyright their content a way to stick it onto a secure, public ledger.
This is useful for stock images as they could set a smart property and give certain rights to someone that wants to use the image on their site. The image or API or something would check the network to verify that there rights for the subuser to use the image like whenever it is shown on a website. Nxt is good for this especially with the transparent mining.
I don't know how this could be implemented, but there are something like a Trillion digital images produced every year with only a few being digitally watermarked by highly expensive services. I think cryptocurrency can solve this and make it very easy and cheap track the rights to one's content.
I know most would want to pay to use those images that are just floating around the internet. Attaching some kind of address and/or smart property to an image can make it easy for those that want to do right by an original content owner and give them something, even if it's just a fraction of a penny.
So say you create a viral image that gets millions of views.
Right now that person most likely gets zero for it.
But if somehow all the servers and/or clients had an easy way to pay fractions of a penny to the original owner, that would make it easy for everyone to pay to use.
I don't know much about programming these days, but I think this could be a killer app if implemented correctly. The cryptocurrency that it gets attached to could be the de facto for content rights management and payment. This would seriously enhance the worth of the cc (cryptocurrency) that it is tied to by many factors IMHO.
What do you think?
sorry if you don't follow what I am getting at, basically it's some kind of DRM utilizing a secure, decentralized public ledger.
I have some NXT, BTC, LTC so I could send some to whomever takes this on to help the currency grow.
Definitely an interesting idea, could probably incorporate Alias, Messaging, and AE to tackle the project. Any kind of DRM solution utilizing Nxt would be huge. I agree, it's really a very good idea! |

2036840723237273850, thanks a lot! But please hold on, I didn't yet do anything useful  So start.....what can u do? And to anyone and everyone sitting on the sidelines: GET INVOLVED !
Every small contribution helps. If u want to actively help NXT: get off yr ass, look around, find somewhere u can help and dive on in. Don't hang back because u might not want to look foolish or make a mistake. No one here is perfect, (except me, of course), just do your best. Surely, no one sitting on the sidelines can resist such an invitation. One humble question: does translating around 500 wiki entries count as an involvement? My remark about "anything useful" meant that I'm really interesting in constructing a reasonable math model to estimate probabilities of a successful attack on the network, but didn't yet advance too much on this. ooopsss.......maybe I should have been a little less blunt. Yes, 500 wiki entries counts. Sorry, I took your "I didnt yet do anything useful"post at face value, didn't mean to tread on your toes. My call to arms was really intended as a general shout out to anyone and everyone who is on the bench right now. So i'll apply a quick edit......good work with the Wiki and the brain-melting math, btw. No problem, it's all right |

Je dirais que le NEM est le plus sérieux entre eux. Par contre, le NEX est annoncé par quelqu'un qui n'est pas sérieux...

I'm so glad to see a real math person on the case. I just tipped you 10 Nxt. Please stick around to help sort though all this madness.
Thank you! And it's not madness, I'm starting to find it very interesting |

Did I get it correctly? If yes, what happens then (assuming 1 wants to continue with its bad behavior)?
I think you've got it correctly - the reason that 1 can't continue this behavior successfully depends upon his control of the future blocks (which he can't actually *control by himself* due the random nature of crypto hashes). So the *evil block forger* actually needs *evil friends* to help him. If he has enough friends then he can win but the actual probability of this is why we need a math guy. OK, it's good that I'm starting to understand something. Sorry for being soooo slow, but that's on purpose It's better to clear any misunderstanding on an early stage. To proceed, I need to understand: 1. How the "weight" variable is actually computed? 2. In particular, for what reason the weights on a "bad" branch are supposed to be much smaller than on the main one? 3. Assume that a node sees at least one neighbor with a different version of the blockchain (from the blockchain that our node has). How does it decide, which is the "correct" one? Then, do I understand correctly, that the main object of interest is the probability distribution of the length of the "bad" branch? That is, we should be able to issue statements like "given that the bad guy has X% of all NXT, he can grow a bad branch of length at least 10 with probability at most 0.00000000003", right? On the side note, there is probably also a question about penalizing "suspicious" accounts. Because if the rules are too strict, then inevitably your would penalize some good guys too, and so maybe an attacker can invent a strategy to break the network because too many nodes are penalized. Is this a possible issue? |

Maybe, define it this way:
- assume for now that we have a static picture (no transactions between accounts), and there are accounts (nodes) 1,...,N with balances M_1,...,M_N on them;
- the time is discrete, and at each moment k each (active) node j calculates its current weight W_k as a (randomized?) function of M_j and B^j_{k-1} (the previous block in the blockchain that the node j thinks to be "official")
- the network then chooses j_0 such that W_{j_0}>W_i for all i not equal to j_0, and lets the node j_0 forge the block B_k; then L_k=W_{j_0} is the weight of this block.
Now, what I don't really understand, is how a node really determines, which branch is "official"? By looking who has the majority among its neighbors in the network?
Now you lose me with the math (as I said that is not my field) - but let's try and move forwards. There is "no official" branch. Each node makes it's own decision about its current chain according to what it sees. So one node can end up on a "fork" and if it goes too far down that fork it may never be able to get back onto the "main chain". So the "main chain" is the "best chain" in terms of the "weight" of every block in it. Yes, "official" is a bad term; I meant the "main chain". Let's, maybe, consider an example, to help me understand it better? Assume the node 1 is run by Emule a rich person, who, nevertheless, wants to destroy Nxt for some reason. Assume also that 1 is connected to 2,3,4 in the network. At some moment k_0, the node 1 intentionally delays broadcasting its current weight W_1 (should denote that W_1^{k}, but let's not overcomplicate notations), so that at the moment k+1 all nodes except 2,3,4 would think that B_0,...,B_{k_0} is the main blockchain (where B_{k_0} was forged by someone else, say, node 7), while 2,3,4 would think that it is B_0,...,B'_{k_0} (where B'_{k_0} was forged by 1). Did I get it correctly? If yes, what happens then (assuming 1 wants to continue with its bad behavior)? |

Can you define (in simple terms) the math model and the question about it that you need answered? I'm a mathematician (Probability/Stochastic processes), but understand little how cryptocurrencies actually work, I have to confess that I understand almost nothing of the tech talk over here...
I will try my best (math is not my strength - logic is). Basically the way that TF works is that there is a crypto hash for each block which was calculated from the previous' block hash and the "forgers" account. This hash then determines who's account is the "best" to forge the next block so in a perfect situation if we consider that the max. "weight" of a block is 100 then you would see a blockchain like this: A(100) B(100) C(100) D(100) but things aren't perfect as some people won't forge (or pass on their forging right) so the network allows other "less perfect" blocks to be announced and each node will accept the best one that they see to try and keep building on the chain. A(80) B(90) C(50) The problem of "forking" is because each node can't see everything in the network (due to latency) so you could also end up with: A(80) B(95) C(10) with these "forks" ending up becoming "ignored" because a longer "better" chain has been noticed by the node. So the problem we are dealing with is that B(95) could "hide" their block and then announce it *after* B(90) which would at least for 1 block make it a "better chain". But as others will build upon what they see then it won't necessarily *matter* that B(95) was better than B(90) because C(50) is better than C(10) and so B's attempt to "create a fork" will fail. If though someone has the ability to produce a better B, C, D, E, etc. then they could replace a large number of blocks. This is known in Bitcoin as the >50% attack. We need to work out the probabilities of all this including how "penalising" a node for "not forging" changes this. OK, let's try to make the notations more clear. Who are A,B,C,D? Blocks, right (not nodes)? Shall we write "A(80) B'(95) C'(10)" in your example then? Maybe, define it this way: - assume for now that we have a static picture (no transactions between accounts), and there are accounts (nodes) 1,...,N with balances M_1,...,M_N on them; - the time is discrete, and at each moment k each (active) node j calculates its current weight W_k as a (randomized?) function of M_j and B^j_{k-1} (the previous block in the blockchain that the node j thinks to be "official") - the network then chooses j_0 such that W_{j_0}>W_i for all i not equal to j_0, and lets the node j_0 forge the block B_k; then L_k=W_{j_0} is the weight of this block. Now, what I don't really understand, is how a node really determines, which branch is "official"? By looking who has the majority among its neighbors in the network? |

From the text by BCNext/cfb, it seems so to me. don't know about the math
We really need the math - so if we have any math guys in our community there is an opportunity for you to earn some NXT or BTC for helping out with this and some other analysis. Can you define (in simple terms) the math model and the question about it that you need answered? I'm a mathematician (Probability/Stochastic processes), but understand little how cryptocurrencies actually work, I have to confess that I understand almost nothing of the tech talk over here... |

You know how I know BCNext is not a native English speaker? A native English speaker never would have used the word "forge" positively in connection with currency.
+1000. This is a real problem for anybody learning about NXT for the first time. There is a valid and legitimate use in English for "forger" as being "one who heats and works metal", like a blacksmith. But the FAR MORE COMMON use of "forger" in English is "one who creates fake documents, particularly financial ones". The same problem in Portuguese, by the way. |

Two choices: 1. Either change the plans we agreed to when entering this IPO and thus give all the coins to me (just as "fair" as giving more to 1st stage investors who now want to change because the applications were different than they expected) or 2. Use the original plan. Changing plans because it went differently than we all expected is a sure fire way of having two month of bickering about the fact that you decided to change the rules before you even got started. I expected things to be different, too, but hey ho, sometimes life isn't what you expect it to be.
(choose option 1)I'm afraid Option 1 implies that the coins will have no value at all |

Voting would be the best in this case, democratic voting is the most fair thing to do in this case.
As usual, the question is: who will have the right to vote? Also, as far as I remember, it is already planned that the early birds will receive more in the (unlikely) event that investing on the 2nd stage is more profitable. Anyhow, I'm against introducing drastic changes to the initial plan (just in case, I'm among the first investors, invested around 1/2 of the max amount). |

Nxt's 3-months Birthday in 2 days! А самая левая самочка (на фоне окна) ничего так, я бы ей вдул... Очень похожа на одну мою знакомую гречанку. Ну... эххмм, ладно, а то вдруг жена прочтёт... |

+1 Also, if he was a scammer, there would be no reason at all for him to disappear now. Quite contrary, he would be writing tons of posts to convince people to invest on the last day. |
