So why does nxt have this problem too? Is this something inherent to crypto currencies?

Can it be fixed?
Will it be fixed?
What should exchanges rely on instead of transaction Ids / transaction bytes?

Only thing I can think of off the top of my head is individualized accounts, so you can constantly poll getGauranteedBalance on them.

Question: If what parts of the transactions can be faked? The sender ID? All of it?

It's a problem only for exchanges that rely solely on transaction id. It doesn't need to be fixed. An exchange is supposed to pay attention to timestamp and other parameters of a transaction.

The idea was to prevent hacking and emptyings.

Is almost impossible to make a error sending by placing the phrase and all. Tongue

My next idea to prevent hacking and emptyings consists to create a second key 16-32 characters.
That would register like the ALIAS. Key is not used to unlock the account, only to send!
The key can be changed.


BCNext implements Account Control. Let's wait for that...

I think that's not the point here. Consider this:
Code:
b = f(a)

c = g(b)

d = h(a, c)

Let's assume c results in -2 with a certain b.

Even if c=-2 and c=3 are interchangeable mathematically, h might not work as expected as the pair (a, c) belong together.

So, it could be the case that h(a, -2) != h(a, 3) for the very same a. This must be avoided at any cost.

That IS the case, as h == verify, verify WORKS (validates) on "3" (and it SHOULD work on "3") and doesn't work on "-2",
(that's why you can see those "Generated incorrect block messages")

tell you DGEX to send and receive your deposits in 10 minutes. lol


I don't know what Dgex problems are but I can use bter to sell and buy Nxt within minutes.

This is DGex problem, not Nxt.

Would you buy online clips (porn or not)  with Nxt if you get the download link AFTER  24 hours?

That will make Nxt useless.

Even bitcoin with 10 minute for one confirmation is faster.


I will accept Nxt as a merchant with even one confirmation (1 minute), but I won't accept Nxt if transactions are reversible for 24 hours.

I would rather then find a better currency.
no body said the transaction is reversible.

I heard on Lets Talk Bitcoin a few nights ago that the Zerocoin protocol is being developed for NXT.  Does this mean that NXT is developing a Zercoin-like protocol or have the Zerocoin developers decided to build on top of NXT?  Are the developers working together?

(that's why you can see those "Generated incorrect block messages")

The point here is: 'SHOULD work on "3"' has to be proved.

Maybe, there are some negative numbers c so that (a, c') validates ALTHOUGH a is invalid. (where c' is the positive equivalent of c)
Maybe not.

So, proof of the algo as well as the code is needed.
