Brainstorming
I'd like to introduce a concept of a new feature called Account Control. This feature will allow to do different things with ur accounts. For example, u will be able to set a lock on an account to prohibit any outgoing transactions until a special condition met (e.g. an incoming transaction from a predefined account).
Love it. Conditions could be: incoming transaction from another account, only at specific times, second password(?). Or it wouldn't be locked only for specific amounts or receiver addresses. We should keep in mind that the functions need to be simple. Of course with genius coding behind, but the end user must understand the features in a second. Another example is Pooled Forging, when an account leases its forging power to another account.
I have a question first: When Alice's account forges a block, is Alice able to forge the next block(s) also or is there some locking going on (i read about it somewhere)? Without locking for the next x blocks, we could get some centralization (like big forging 'banks', getting bigger and bigger). edit: ok, slow writing. this was mentioned three posts above mine. |

I'd like to modify this concept a bit in a universal way. I'd like to lock a portion of my account (up to the whole account) I want let's say invent a turtlecoin with value xx_NXT, grant a specific account (other or mine) the right to pull this turtlecoin if he sends a password and define a timeframe during this has to be done. after the timelimit the turtlecoin becomes NXT again. During the timeframe the turtlecoin is locked for me. this way the NXT-client could print a QR-Code with the generated password, I go to the petshop and the owner can pull the turtlecoin with it. -> I get the turtle and both are happy  this is of course only one application for this feature. of course turtlecoin can be replaced by amout xx NXT. another idea: it wouldn't be hard to implement an escrow this way. I wanna sell a turtle. buyer sends me pass for turtlecoin, which I only can pull after turtle reached buyer succesfully. if he doesn't confirm turtle reached him alive, the turtlecoin becomes invalid for me and him also and goes as NXT to a predefined social fund. the buyer can trick me, pretending the turtle was dead, but he won't do this very often, because the network stores unsuccesful trades. Poor turtle. Nice idea. Like a voucher ( or paper money! mindblowing). It could also work as a guarantee. The coins are blocked for you, reachable for the other party which could grab them if a special condition is met maybe, but you can still forge with them. edit: And they are called nxt coins (finally ). Backed by NXTs. |

And in the end, we will have a big pool with all Nxts in it  On the subject of large pools forging... Assuming all one billion nxt contributes to forging, an account (or pool) that has 17million balance will forge a block on average once per hour, i.e fairly regularly. Any business that needs to execute lots of transactions each day (e.g. an online wallet service / exchange / alias registrar service / poker game) could lump all its transactions from the last ~1hour into that one block and get them executed without fee. Or rather, it gets its own fee; but same result. So, big players with big wallets and big transaction volumes will end up not paying any fees, whereas the small fish will have to pay fees. Is this a likely scenario, and if so is it a problem? |

Well, this finally seems like a fine candidate for a new RaspNXT. My RPi is down right now for some overclocking tests. Will update, test and upload later. |

don't see any problem there.
Maybe it would make sense to replace unlimited by an defined number to avoid "Monopo(o)ls".
(don't know how to do in open source SW)
Big pools could become bigger and bigger due to more frequently forging.
This allure (more accounts => more frequently forging) + self gaining...
And in the end, we will have a big pool with all Nxts in it As I said ... It was a big pool, now its a big pool, always be a big pool with all NxT in it ;-) If you zoom out far enough  , every decentral system becomes centralized by it self ;-) |

best ever  just created pincoin Pin I'm kinda sad I didn't see an option for maximum number of coins. I wanted to make OneCoin: The Rarest of CryptoCoins(TM). |

That's the reason I was mentioning to set maxNumberOfAllowedForgingClients != infinite. This would lead to an minimum dispersion, affected by the value of maxNumberOfAllowedForgingClients. |

Account number 12956190138975700589 was incorrectly typed with an extra 1 at the end: 129561901389757005891. This is not a valid account number (it exceeds 2^64) and so resulted in overflow and was interpreted as 434692873790144579. I have added code that checks and prevents such overflows, so from now on this would return an "invalid recipient" error message. It is important to note that typo's that result in a different but valid account number will still not be caught, but in those cases it would be more obvious to the user that he has made a typo. So if the user enters the account as 12956190138975700588 for example, it will be accepted because this is a valid account number.
Most importantly, there is no evidence in the above case of a random, memory corruption type of bug, as some have feared. Adding checksums as a way to prevent user errors is a different issue, but there has been no memory corruption at play here.
Wow, I am ashamed. It indeed looks like my stupid mistake. Still there is a small possibility that that last 1 was a result of a memory corruption, because I do not type anything, I use the mouse to copy/paste. What happened in the old version when the account number was pasted twice, so it read 1295619013897570058912956190138975700589 ? |

Hi dudes. I created few days ago fan-page vk.com/nxtvsbtc on russian social network to promote NXT for russians, belarusians and ukrainians. Now we have over 2500 followers. We start competition today. People must join to fan page and share this post( video about nxt) http://vk.com/wall-64086699_17 The competition will finish 20January. The winner must has more re-post of this video from his profile then others. Bounty is 1000NXT! After finish we will start next competition. Many people will know about NXT. I'm waiting my withdraw from dgex and I will thank you if you will donate this project. Best regards NXT 5552153634766291106  |

I thought about it too. Would be strange not to notice such a long number, though. I also thought maybe the field had a limited length and on double-paste it became 129561901389757005891, but it doesn't seem to have a limit. It's also possible that it appended to itself internally as a result of corrupted memory. Anyway, the important thing is how to protect against it in the future. I hope the developers are brainstorming how to do checksums in the best way and how to migrate to the new address scheme and will come back to us with a solution later. |

You are wrong, or maybe you have an agenda? Or just too busy to read ? This was THERE on the DGEX site, FAQ section DGEX promotes NXT trading by lifting trading fees at least in the beta period. We charge 0.9% of all Bitcoin withdrawals to cover transaction fees and other overhead costs. NXT withdrawals carry no fee until the end of 2013, we absorb the 1 NXT transaction fee. Peace.... It's good to see some reasonable behavior in here for a change!
So how much money you wanna rip off this great community and altcoin? 800k NXT not enough, I guess. Fuck off, bastard!It's not just confusing, it's total bullshit. Graviton made for the community more than most of us. If someone doesn't like fees, then remember how much money did you make on Dgex or outside it but because there was such thing as Dgex. If there was no Dgex and nextcoin.org we'd still have Nxt around 0.000001 Btc and one thread here on bitcointalk.
When one do not charge you to get in and later do not allow you to get out for free than it is called a scam. Very simple. On a funny note, check nxt:rawdog Peace! First of all he notified in advance about fees. There was no info on DGEX website. I don't give a shit if he posted it elsewhere. I use his website and I expect info there.27.12.2013: Server migration over, smooth sailing! 16.12.2013: Fee structure change, instant BTC withdrawals available! 08.12.2013: Email server changed, problems should be gone 02.12.2013: NEXT Forum at Nextcoin.org launched! 28.11.2013: Launch of NXT trading. Welcome! |
