CfB keeps hinting on something fantastic coming from BCNext on the use of these 20 digit short accounts, so I doubt what you ask will happen.  Although I wonder if this fantastic thing is the ability to mine for that 'hiberNXT' whenever curve asics become available.

I'm not hinting, the idea is simple:

This gives us ability to find out what coins r lost and what coins r hoarded.

All, consider this as fair warning.  Buy 1 alias for 1 NXT or something. OR IM COMING FOR YOUR NXT WITH MY CURVE25519 ASIC IN 2015

We don't integrate some sort of CRC because of saving a tiny bit of memory in the core code and because sort-of-CRC could be done in a/the client, right?
No, because in the core and when sending across the network the transactions are already signed with the sender public key. Any corruption in the transaction content would automatically invalidate the signature.
So what? Buffer, from which recipient's address is taken could be corrupted, user could made a typo.

Maybe somebody don't understand. One can make a very easy experiment: send small amount of Nxt to a known address whith one digit randomly changed. Such transactions are accepted and gladly confirmed by the network. That wouldn't happen with Bitcoin or any of it's copycats.

There is only one proper solution for that. Extend Nxt address with (preferably) 4 bytes of checksum. I'm not a Java developer, I don't know details (and I haven't read the code), but I stronly beleive there are readily available classes for big ints, use them instead of primitive data type which is apparently being used for addresses now. Or write your own class. You need a method to take significative part of a new address, method to convert old address to the new form. From block XXXXX use new addresses, make proper conversions when you deal with old blocks. That should be easy.

This solution is ugly.

1) You will have aliases like CfB\0CFA67D9 - looks ugly
2) In another client your alias will be just CfB => people will get confused what your alias really is.
3) Some people won't use aliases at all and will continue to send money to nowhere.

It's a total mess.

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). Another example is Pooled Forging, when an account leases its forging power to another account.

Please, post here what u would like to see in Account Control.

Nxt transfer, Alias selling and buying prohibition until a special condition met.

But hackers could probably register, when the special condition happens.

It's a client soft issue.

Would you stop being silly?

Ok, core devs, consider this very real scenario:

I am building an automated payment collection API right now, similar to blockchain.info. Mostly for the exchange, but I will make it available for others too.

So the merchant calls this API via URL to generate a unique address for each customer and also passes the main account number to forward money to.

And now all your silly talk about how client verification is enough is shuttered into pieces, because now we have a very long and unreliable path between address source and the place where transaction is actually signed.

So what happens if something goes wrong along this path? Human error, network problem, bug, glitch, anything.

Bitcoin: Money isn’t forwarded.
Nxtcoin: Bam! Brains all over the place.

I don’t know how things are going in that perfect, illusory world of yours, where memory corruption doesn’t occur and everything’s rosy, but here in the real world, losing money is kinda big deal.

So why are we playing Russian roulette with it?!

Would you kindly pull your collective head out of your collective ass and start taking this issue seriously?

I post a few days ago in nexcoin.org that aws.amazon.com cloud gives 1 year free micro t1 VPS
I have a windows one free and now I added onepaid both with slightly more than 600mb ram. It seems that the nxt nodes run ok on them. I don't have them hallmarked but I thought we run as many like them as we could to support the stability.

It costs 0 for 1 year.
Go make accounts in aws.amazon.com and set up a VPS with nxt node.
You need to modify the web.xml
         <param-name>myAddress</param-name>
         <param-value>PUT THE VPS IP HERE</param-value>

Don't put money to fogrge just run nxt client.

Just running nxt node (client) with 0 nxt in it will help the stability right?? or am I confused again!!!!

Would be great if you could write up a guide on getting people up and running on AWS. Windows and Linux.
Bai,

I signed up and I'm at my console home page. How do I set up a VPS? Do I launch an EC2 instance? Which flavor (linux, windows) of Amazon Machine Image should I choose?

Also, has anyone confirmed that this will help nxt network stability?

Why am I doing this when I can't even get my client to run properly? Tongue

I will do Windows set instructions later on tonight. I am with a customer at the moment and cannt do any work on NXT!!

Would be nice if some of the leaders/genii can confirm that this will help the stability of the newtork else its waste of time.

Step by step with images how to install a VPS in amazon:

AWS (aws.amazon.com) consol set up of a windows server to allow NXT running on it. Should be free for 1 year if you run 1 instance only and its t1 micro (at least it is free for me).
Step are the links (images/screenshots) below in chronological order:
They are really every click so its not as bad as it looks!! less than 20 clicks (simpleS)

After you create and connect to the VPS using the remote desktop shortcut you need to set up Firewall Rule on the Server to allow everything for NXT.
Here are the steps:

Why is that silly? Anyone can build on top of the NXT API and put whatever verification checks they want in a client.

It would take a few days (or less) to hack together an "idiot proof" send money page that uses aliases, verifies the recipient account exists, and asks 3 times if you're really really really sure.

Exactly it's a user/client side issue.

At the end of each month I will donate some of them back to the community.
This is separate from my main wallet so you can keep track of them. I will keep them in there and only use them for hosting.

Hi, download 0.20 here: http://nxtra.org/mac

The reason you got that message is because they're using another location for downloads now (hopefully the final time they change it..) - and what was compared was the hash of a HTML page returned at the old download location no longer in use instead of the zip.
