Please let us know what NEX will do compared to NXT.

(1 ) What database will you implement? What programming language btw.?
-> LevelDB.  Java
(2 ) How is the proposed security mechanism? Some pseudo-code would be nice.
-> Bitcoin like Wallet
(3 ) How is the currently implemented PoS insecure? How do you intend to improve it? Give some technical details please.
-> Hybrid with Proof of Burn
(4 ) How is the address space of NEX designed?
-> NEX id is just the public key of the user pass phrase.   There is no checksum.  There is no user recognizable identifier that it is a NEX id.  Public key therefore can be hacked because pass pass phrase follows human patterns.
(5 ) Where did you upload the alpha version of NEX? It's open from the beginning I assume, right?
-> When available, we will people know.
(6 ) You are Carlos Perez, correct? Who are your developers?
-> Carlos Perez is the lead developer.
(7 ) You plan to rise 1 Mio NXT as buyin,  how is that fair compared to the 21 BTCs?
-> We limit the amount of NXT you can buy.  We keep it open until all 1 million is consumed.   We do not close it early.
(8 ) How will you defend issuing NEX to the same guys (sockpuppet problem)? What will be your stake in NEX? What stakes will your partners and developers get?
-> We have are engaging several partners and this has yet to be determines.  The final distribution will be let know before a single NXT cent is spent.  Oh... sorry... did not realize that NXT doesn't have decimal places.

Best of luck with your Nxt.
