Good point, I could try it with some other materials. We will see how it will look like.

Well, a little disappointing that the interest seems to be close to none. I guess that's my own fault, though.

If you are curious what I want to do and why donating makes sense:
I want to create a person-to-person exchange for NXT, similar to the functionality of LocalBitcoins.com, providing a secure and easy way to trade NXT (for fiat).

In case you have any wishes or suggestions on how you would want to use it and what to expect from such a service, please let me know.

Also, I remember there being at least one bounty offered for accomplishing this task. Are these offers still valid?
Of course the idea itself is interesting enough to invest effort and time, yet neither infrastructure is for free nor do my living expenses pay for themselves once I go full time on this project.

The auditor must check that code correctly does what it's supposed to do and doesn't contain flaws.

I would do it.

I was curious of the requirements the auditor shall fulfill.

S/he must be a Grandmaster of Cryptography.

That's an argument from authority. That's not how you prove things. Even if Schneider were to say "it looks ok" it doesn't matter much.  
You prove code by formally verifying it and giving your proof. Someone could post it anonymously and it still would be valid.  
There's always the possibility of bugs due to bugs in language implementation itself, or even hardware, but there's no way around that.  

Although the Nxt Asset Exchange will be a useful addition I think that we are missing something that could be much more useful (and perhaps a "killer" addition) and that is "atomic cross-chain crypto-currency transfers" (some of you would recall I've already mentioned it).

As far as I can tell no-one has actually built such a system and also so far I can't even tell if such a transfer using TierNolan's approach (https://en.bitcoin.it/wiki/Atomic_cross-chain_trading) has ever actually been tested (if anyone has a link that shows such a transaction having taken place then I'd be very interested to see it).

IMO this would really be a "game changer" as it could allow people to trade crypto's directly without an exchange and without risk (beyond having to wait for the "refund" problem that is necessary for TierNolan's solution in case the trade doesn't get finalised).

It wouldn't work fast enough to do "day trading" but for those not in a huge rush the promise of 100% secure transactions with only minimal blockchain fees would be pretty appealing.

What do you guys think?

Nxt provides another way to create "altcoins". It does make sense to implement such the feature for BTC-NXT trades... for next 2-3 years. But I doubt anyone will use Bitcoin in 2017.

it be the killer addition!


Even if people dont use BTC which I doubt, they might use other coins like Dodge:)) or they might have other type of assets, shares or something else so a trustless link would rock!
If I was more clever would sugest how to do it but I hope some genius from here can create it.

I like it the way it is described here:

But, yes. Day-Trading could be done only with in-chain-coins.
