WARNING!
The vote is currently tied at 3-3. Hopefully someone new comes along to break the tie for Team Monero before 0:00 UTC to avoid any delays.
Qxd4 (smooth, articmine, xmrpromotions)
Nxd4 (8xmr, lucylovescrypto, erikgoff)
If you have a strong preference for one move over the other it might be helpful to provide your reasoning in attempt to influence other voters.

Nxd4. queens have be left sleeping in 
More detailed explanation of each constant choice can be found there: http://cr.yp.to/ecdh/curve25519-20060209.pdf
I am still studying the paper, but must say the more I learn about elliptic curves the more interested I become.
Nxd4
Qxd4
I was pretty sure you were going to do that, or maybe Bb5
Let's hope we don't get outvoted
I was planning to vote Nxd4.
Lucky for Qxd4 voters I happen to be watching the World Cup Finals live online right now. Peter Svidler just played Qxd4 in the same position

I vote 4.Qxd4 in the spirit of the World Cup

Team Monero (white pieces) vs. Team Boolberry (black pieces)
white to move
1.e4 c5
2.Nf3 d6
3.d4 cxd4
Based on the votes in this thread Team Boolbery has chosen to play cxd4
Now it is time for Team Monero to respond. Votes will be counted at 0:00 UTC tomorrow.

cxd4
I like this opening!

Since I was 2 hours late with the count Team Boolberry only gets 22 hours to reply this time. I doubt anyone will object based on how early we are in the game. Based on the rules in the OP if votes are counted well after 0:00 UTC technically the other team should be getting another day to respond. As the position becomes more complicated and in cases when I fail to count votes on time either team can claim this extra time if it wishes. Most days I expect to be able to count votes reasonably close to 0:00 UTC.

Definitely no need for a time extension on this move
I vote cxd4 and will be shocked if the move does not capture most or all of the votes
It looks like we are headed for an open sicilian despite the wishes of you and ArticMine.
I was considering changing my vote but I guess it wouldn't have mattered even if I hadn't missed the deadline. If there is a discussion after the game I will explain my reasoning. Onward we go in any case.
my vote goes to Kb1-c3
This may seem strange to those that can spell but in chess notation we use the "N" for knight since "K" is used for the king. It looks like we are headed for an open sicilian despite the wishes of you and ArticMine.
I recommend cxd4 as blacks third move.
I vote for c3. There are alternatives to d4 in this position
Sorry for being late with the count. d4 remained the clear winner by votes
Team Monero (white pieces) vs. Team Boolberry (black pieces)
black to move
1.e4 c5
2.Nf3 d6
3.d4
Based on the votes in this thread Team Monero has chosen to play d4

I would like to join the d4 bandwagon!
My single biggest question after reading the entire paper is the how did they choose their elliptic curve constants? The protocol appears sound; who chose the constants? Will there be a plan for choosing new constants in the future if needed?
As I understand it the constants were chosen by Daniel J. Bernstein. I think this is noted in the white paper but may have been missed during that initial review when cryptonote suddenly dropped out of the sky.

I'm not a cryptographer so I may be getting some of this wrong.

I know that Monero and Boolberry did not create CryptoNote but have improved on it. Any guesses for the reason the CryptoNote creators selected a relatively new cryptographic hash function?

I've not seen any answer to this, though you could try asking on their forum. That can be hit or miss. Some of the people posting there on behalf of "cryptonote" obviously have technical knowledge but others are just clueless.
Daniel Bernstein seems well qualified to make that decision. Maybe he will share his thoughts with us. Is he on bitcointalk?
https://en.wikipedia.org/wiki/Daniel_J._Bernstein
The second question may or may not even matter (I have no reason to assume there is something wrong with the chosen hash function). Only because of the importance of the decision am I wondering about the selection. I have not registered on the CryptoNote forums but may do so at some point.
Thank you for your time.
1. The largest prime number closest to the power of two (2^255 – 19) was defined for modular arithmetics speed up.
2. The order of group 1 (another large number) was obtained when the group order for this curve was calculated.
3. Basepoint for EdDSA corresponds to the basepoint of Curve25519. These curves are birationally equivalent. Curve25519 uses the base point x = 9
4. Coefficient 486662 for Curve25519 (and, respectively, coefficient 121665 for EdDSA) was chosen the same way.

Thank you for your detailed answer.
I will study the paper you referred me to until I am certain I understand the importance of all of the above. My chess schedule should provide me some flexibility to study more cryptography this week.
