What do I have to do to get on the Nxt TestNet?
Would like to try creating and launching my own asset in preparation for that to launch. Thanks!

does ANYBODY know what it was BCNext wanted from us that we didnt do right? Im still not sure if TF will ever happen, earlier CFB gave an april fools response to a question about TF and if he could complete it
TF is just a proof of concept?  That's why Nxt is as cheap as it is.. just wait until they finish fully implementing it  |

It was the first hybrid PoW/PoS to go to only PoS with 0 premine and no IPO...... others=crap
I think IPO was genius, now they creators have a lot of money that they can use to create a really awesome product. Oh well, I guess we all have our favorites.. Nxt has huge things coming it's way though. |

Not a fan of the website claiming this is the first real proof of stake coin, you guys haven't heard of Nxt or Mintcoin? Deceptive marketing is a turn off for me, otherwise I might've bought a couple for the sake of diversifying..

What prevents the currently picked mining node from only confirming half of all transactions he picks up?
Or from packaging different versions of the block together and passing them to only half the network?
|

more bad news crossover MACD downwards about to happen!  I certainly hope so, I'd love to buy more Nxt even cheaper |

Dude, I just bought 2.5 cent Nxt!! So cheap!

Very nice, I agree, make sure someone helps this guy out! |

A forging node decides to be dishonest to disrupt the network, he verifies transactions but packages half of the transactions into one block, half into another block. He sends one of those half blocks to one half of the nodes he's supposed to passing information on to and the other half block to the other half of the half of those nodes. He tells them they are complete blocks. Now nodes have a fork as approved by the forging node. How do they learn about it and prevent these dishonest nodes?

I'd totally be for upping the price of aliases up to 100 nxt each, don't want them all to run out now.. unless it's already too late. |

I would say lets put this enormous thread on-going, this is where poeple throw their raw idea out and discuss about, where the forum is a perfect for poeple to work and concentrate on that particular features.
I was against this enormous thread at first, but yeah, it's kind of like a chat room with a very long history saved. Think we can reach the limit on number of pages bitcointalk will allow? |

I figured out how to choose a random number deterministically within the decentralized Nxt network, where someone with 90% of the forging power as determined by proof of stake could only get lucky enough to manipulate this number 1 in a billion years at a rate of 1 block per minute. It would only require 300 forgers online, we currently have more than this. If we have get 500 forgers participating this number drops to someone with 90% of the forging power only getting lucky enough 1 in approximately 40 Octillion years.
And it scales nicely and it's fast, could easily be done. No proof of work required. Could probably cut down how long you lock up funds and changes to forging power to 10 blocks, say 60 if you want to be safe. I'm telling you, it's big. Already run it by one person, would like to run it by others.
If I were working for Nxt it'd be a different story but I don't want to just put the whole idea if I can get a bounty on it. If I can proof this, is there a bounty on it? Or you guys already have a work around in mind that could achieve this?
maybe you should pm cfb or JL directly ? Good idea. Also it's a trustless solution, as long as a single peer is honest, it'll produce a truly random result. And that 90% number is if he plays a couple tricks. I think I've got all the attack vectors worked out. Guys, buy Nxt.. it's the future. I PMed them, we'll see what happens. Can't wait to share it, and get people beating it up to see if they can find flaws. Maybe behind the scenes first because unless I'm missing something, I'm convinced this is the holy grail that cryptos have been searching for when it comes to efficiency. |

it is interesting for different reasons - right now this video is super-boring for me, because we already have this and I have spent a lot of attention to mesh networks here: http://justpaste.it/nxt-decentralized-internet (Fiber optic cables are addition by NxtMinnow). So the guy is like prehistoric talking for me. BUT - he was telling to the audience about something new. So the interesting part is - how he decided to do that. By 10 minutes faery tale and 5 minutes of very uncertain datas. No techbullshits The biggest issue I see is you have to really quickly choose which neighbor to forward each packet too. If you have even 1 extra ns of latency per person when forwarding it on but multiple that by thousands of people along the way, it adds up quickly. Anyway point is, I'd be interested in discussing this further. I actually spent a little bit of time thinking but this idea, I'm thinking it could be done with special ASICs and an algorithm that routes network traffic based upon geographic location. If anyone wants to, I'd love to bounce it around a little bit. |

The only thing you have to predict correctly is who will be the author every single one of the next 1440 blocks. (a difficult task no doubt considering you need to pay 0.1 nxt for each guess) You dont have to predict correctly what transactions will be in those blocks. This is important because it protects against gaming from transactions to be specifically tailored to allow you to author future blocks.
Why does predicting who will be the author of the block help you? Because you can change around your nxt in order to make sure that the hash of the account balances leads to you being the author? Also not sure why it's 0.1 nxt per guess? Why actually move around the funds? Why not just do it all offchain, use your own hashing function and when you find one that works, then you do the actual transaction? And you do have to predict what the account balances 1440 steps into the future will be because it's a hash of those account balances that determines who will forge and small changes to those account balances should lead to big changes in the hash output, right? Something obviously hasn't clicked yet.. heading to bed hopefully it will tonight, thanks Anon 136. |

As I understand it, the way Nxt currently picks the next person to forge a block is that it hashes the account balances of the accounts that forged 1440 blocks ago, right? Somehow this hash is weighted based upon the amount in people's accounts, right?
It has nothing to do with 1440 blocks ago - the next "best" forging account is according to the hash of the last forged block (which is weighted by the account balance). Ok, so the reason for making someone wait for 1440 blocks before adding new coins to their forging power is because in that way a superpowerful machines can't shift their balance to make sure that they will be forging during the next block, right? Because there is no way that you can predict that far into the future what the account balances will be, because you'd have to know how everyone else will be shifting around their money within the system, right? Why wait 1440 blocks? Wouldn't 100 be sufficient? Also I thought there was a propagation delay before everyone else saw the next block and all the updated balances right? Otherwise, why wait 10 blocks for confirmation? Why am I not confirmed next block? no 100 wouldn't be nearly enough. (im skeptical that 1440 is enough if i had my way it would have been 10080 because there is so much at stake) there wouldn't be enough permutation in that space. You have to understand the incentives at work here. if you can front run like that you gain control of the blockchain for ever until we notice and roll back the chain to before it happened. so there would be incentives to guess over and over and over. you could even analyze the network to see what stake forged and how often, what times of day certain stake forged. all sorts of novel ways can be imagined to analyze that data to make your guesses better. I thought the whole idea behind a hash was that small changes now make wild changes in the future, right? So one person moves his account balance and the forging power assigned to that machine changes 1440 blocks later, so unless you predicted every single block correctly for the next 1440 blocks and you can't change your account balance fast enough to change this 1440 blocks into the future, right? Because in order to change when you forge, you have to know what all the account balances are going to look like 1440 blocks into the future and move your balance to make sure that hash works out to be your machine, right? Or is the idea that you can selectively not include transactions into the current block in order to change who forges next block? |
