NXT :: descendant of Bitcoin - Updated Information

[bidji29]

This is what I plan to do next:

1. In 0.8.4 I am adding the ability to easily switch between real net and test net. First, this will allow anyone to use the test network with just a single change in nxt.properties, no need for a different client (of course for features like Asset Exchange one will have to use Wesley's client, but the Nxt core code will be the same). This will allow many more people to participate in testing. Second, by having the test network and the real network run exactly the same code, with the only difference being at which block height features like AE and Voting become enabled, there will be no risk of additional bugs introduced in porting, or any need for porting of code from test server code to main code.

2. We need to get the Asset Exchange feature rolled out. There is one remaining critical bug, the wrong calculation of unconfirmed asset balances, which I have tried to fix in the latest 0.8 code, but haven't been able to test yet because the test net was still on 0.7.6. Thus the importance of the previous point about having test net in code sync with the main one.

3. Before actually enabling Asset Exchange, I need to make the transition from storing transaction amounts and fees in Nxt to nano-Nxt (0.000000001 Nxt), or whatever fits in a Java long, given that the max possible balance or transaction amount is 1000000000 Nxt. I previously thought about adding a new transaction type, but this will be more complicated and ugly in the long run, so better do it right. At first this is just about increasing the precision at which amounts are stored, enabling actual usage of fractional amounts and fees will be done at a later step. But this has to be finished before the AE is turned on, it will be much more difficult after that. And it will have to be very well tested, so again we need a reliable test network.

4. I need to move the remaining classes that are still stored in memory only - Account, Alias, Asset, Order... into the database. It is not critical yet, because they don't take much space, but has to be done before it becomes a problem, especially with the Asset Exchange that currently needs to keep all open orders and trades in memory.

Are you gonna use floating point?

How much was the fatal flaw worth? I guess that money can be sent to community fund now? (Or used for crypto audit)

Guys I need some links for educating someone in NXT!

Is there any concerted effort being made to compile information to a single, comprehensive source? there are a lot of places to find info, and a lot of people putting out info, it may be a good idea and a good time for there to be an effort to consolidate and reorganize usable information to a single and definitive source and to coordinate this effort between the people who are working on it. There is so much info out there in so many sources, and in so many forms and styles that it is kind of confusing and really a lot of work to self educate on NXT; And there is no form of cohesion or method to its structure. There IS no single article, blog, interview, podcast, forum thread or any other media source that does it justice as a stand alone source of info. Anon136 was posting last night about how he felt he had given a bad interview on NXT, but that only stands to reason, as the nature of NXT makes it impossible to be educated on in a brief info session, and the lack of cohesiveness in the information that is available only serves to magnify this. It may be a good time to start a coordinated effort to supply a source of info that is more unified, accurate, and complete and is organized in a way as to accommodate specific targeted audiences (technical information seekers, and basic information seekers). I think it would serve the community better and make it seem like we had our stuff together a little more to pursue this. I have come into the community just recently and have spent a lot of time looking, and bugging people with questions to learn about NXT, and this has made me aware of this chink it the NXT armor. I think there is a lot of good info out there, and a lot of talented people who know a lot about NXT and care a lot. But with the way that NXT has grown and with the way that info about it is dispersed as a result of that growth it might be a good Idea to supply a more easy to access, consolidated source of info. Get everyone on the same page so to speak. If there were a group effort, coordinated and outlined for that purpose I think it would be beneficial to the growth of NXT, and would not burden one person with such a daunting task.

if there is an effort to do so, I would like to help if there is help needed. If there has not been such an effort I would like to suggest it and offer help.

Something like a NXT secretary, scribe, or archivist?

I did see one case where I submitted a transaction to the dogecoin network but it just never appeared. I am not sure what to do in this case as when I tried to resubmit it, I kept getting error -22, eg. you already sent that transaction. due to the requirement that all servers generate identical rawtransactions, once one server gets in a confused state, it will take some fiddling to sync all three servers again. This is why I am thinking it will take a while before this is production ready. Just need to make all the gateway management tools.

does anybody know how often bitcoin blockchains are rolled back? How much time to be sure it wont be? For larger deposits, I am thinking of issuing assets that cant be redeemed right away to limit exposure to blockchain rollbacks

James I used to work with 3 computers voting for chemical plant control, what we did there was if one computer got confused and was continually voting wrong it would take an update from one of the others and verify it with the other one and if both updates agreed it would reload itself with that copy.

I.e. the continually 'wrong' node would update itself by cloning one of the other 2 (which were agreeing) and verifying itself with the one it didn't clone from, as the other two were agreeing they should be identical and therefore after the clone all 3 are then in sync again.

Don't know if that helps you resolve the confused state.

If you ever get in the state that all 3 nodes do not align then this is a critical state and requires human intervention but I'm sure you know this.

lol, java long is an integer data type not float. That is java basic: http://www.tutorialspoint.com/java/java_basic_datatypes.htm

[redsn0w]

speak of the devil. I just lost internet and all my ssh sessions got terminated along with all three of the gateways. I think there were a few pending transactions, so this is a good test to see if recreating the state from blockchain is working.

I am having some server issues, they keep saying "bind() failed: Address already in use", but all prior instances have been gone for a while...

Edit: OK, all three gateways are rescanning blockchain, just from the first possible timestamp

Could that have been why I was just seeing 'not enough funds' when trying to send DOGE back to my wallet?

I'll try sending back/forth again after my confirmations complete.

It' a bug  in the Nxt server :

Example :

{"balance":684600,"effectiveBalance":684600,"unconfirmedBalance":684300}

Are you sure thats a bug?  That tells me that the nrs instance returning that api has, just prior to that api request, processed a sedMoney request from that account for 3.00 nxt, and that transaction has just not yet been written to a block

Yes , I'm sure

So why the hell he is asking this stupid question? Of course it would not be float.

Well, not everyone knows programming.

i dont like lists with everyone's name except mine.

Really?

Now seriously.

neat. this is what we need. less charity, bounties and rewards and more bootstrapping companies on the blockchain.

If only we had a wiki!

[chanc3r]

I'm considering locking this thread on page 2100.  What are everyones' thoughts?

I don't want to interrupt communication, but I think we would make more progress if we were better organized.

Poll - https://forums.nxtcrypto.org/viewtopic.php?f=2&t=839

Thought on this for a while...

1. We do need to be organised BUT this thread DOES NOT stop us doing that.
2. This thread is a COMPLETE PAIN to keep up with and AMAZING at the SAME time
3. This thread allows for a huge amount of crossover between the vast activity ongoing
4. When we pick up on things we are interested we can find and go over to other threads and stay or leave if we want to get involved deeper.
5. What we could do better is how we take stuff off to other threads where it needed to be worked on sometimes and then bring some news back to this thread.
6. People could also be more responsible quoting and NOT quote an entire page - just the key parts.
7. There are so many people reading and posting lots of new connections are made every day.

I fear that if we lose this forum we will lose something valuable, in pursuit of organisation we will lose something that helps keep us aligned and we will be more organised but fragmented with less innovation as a result.

If people can't read the thread - there is always the newsletters which i have to say is a great commitment by some of the community members to keep up to date.

where can I go to read more on the bug?  FWIW the scenario I described is 100% legitimate, so I must have missed the bug discussion on your particular scenario

Hi Guys,

Just an update on the NXT market at MintPal. We really regret to say that we won't be able to add it. While our scripts were largely working, we simply didn't have the confidence or understanding required for it, in comparison to Bitcoin and other altcoins, especially when it comes to handling trading.

We will be refunding all voting payments in 48 hours automatically, though you can contact us if you require an alternative arrangement.

Full announcement here - https://support.mintpal.com/index.php?module=announce&sec=view&id=7

That is very disappointing (understatement). What did you not understand exactly? What were you not confident in?

Let them refund the money first and then talk about it later.

[CoinTropolis_JustaBitTime]

I blasted out the generous 1 million Nxt donation about 15 minutes ago to our list. CoinTropolis continues to do what we can for the Nxt community. As more press releases are created, we'll get those out immediately.
