Al right so far for an independent review of NXT algorithm, we have some suggestions

1. Andrea Antonopoulos
2. I suggest Emin Gün Sirer at Hacking Distributed http://hackingdistributed.com/
3. Another great suggestion by msin is Steve Weis http://saweis.net/

It is better to contact several of them to see who is interested. Name it if someone has another suggestion. Cfb and Luc are you going to contact them ? Also what kind of review do you have in mind ?

How about those guys from Cornell that published their paper on the 25%/33% selfish-mining "feature" of gaming bitcoin blocks?


That's him Emin gun sirer and his students.

Also

http://www.cs.cornell.edu/~ie53/

Here is what I just emailed him

Quote
Hello Ittay,  My group and I are very impressed with your paper of the bitcoin 25/33 selfish mining risk.  We would like to offer you a fee of 10BTC to examine a few hundred lines of java code that is the base of the crypto currency called NXT.  Specifically, we would like a critique of the sha256 and curve25519 implementations used for block signing and other transaction processing.

Your credentials makes you perfect for this task.  Please let me know your availability or if you are not interested, possibly you can recommend someone who would be interested in getting involved with our project for the same 10BTC fee.

Thanks!

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

He is great but why don't you write to the real professor? Is he more difficult to get? I think msin has also contacted weis.

Why not 1, 2 and 3? If 1 (a with vested interest in bitcoin), 2 (apparently unpopular paper for bitcoiners) agree that the NXT code is sound and 3 (I don't know his reputation... neutral?) then it would give us an unbiased consensus from multiple perspectives.

Of course... paying bounties to all of them would probably be a problem since CFB is only selling 10 BTC for the bounty fund... offer them 1/3 BTC 2/3NXT Roll Eyes

Are any Dev's going to work with Vircurex on this? seems pretty important such a large exchange are asking for help implementing it on their exchange.

Man they don't ask for help. He said he will look into it when things cool down a bit. Why some of you guys are so impatient ? What is the rush? Do you need money next week?

No they specifically ask for help as per the quote below!!

If we could get a developer to follow-up with Vircurex offering help, I'm sure this would move the process along much quicker.

Post it in the NxtCrypto forum, will get better responses.  Ask guys like ricot, ImmortAlex, etc.. they are qualified.  CFB will definitely get him the API.

Available at http://nxtra.org/api -- but I don't think they use PHP. Nevertheless, the concepts are the same and easily translatable to different languages.

I understand correctly that the public key can not be used to encrypt messages, and private - to decrypt?
And i must use another channel for deliver key(s) for message encryption/decryption?

U can use them - https://nextcoin.org/index.php/topic,727.0.html

Cfb and Luc are you going to contact them ? Also what kind of review do you have in mind ?

Programmers shouldn't establish contacts with humanoids imho. We need security review of Crypto and Curve25519 classes. Also Transaction.sign/verify and Block.sign/verify should be checked. And I would like to hear opinion if NRS algo could be vulnerable to attacks described in http://eprint.iacr.org/2007/357.pdf
