It is a bit of a lop-sided argument to claim that bitcoin's client/wallet syncs slower than Dash's.

The bitcoin transactional volume is probably 100 times bigger than Dash. For two weeks that's quite a bit of data to download.

What kind of data connection are you on?

Comparing the two are almost pointless as the amount of transactional volume Dash has is much smaller than Bitcoin collectively.

From the outside looking in it appears that Evan does the following:

1. realizes that anonymity is the hot topic .......BETTER DEVELOP ANONYMOUS CODE!

2. anonymity dies down as a hot topic...

3. speed is now the current hot topic.... BETTER DEVELOP FAST TRANSACTION CODE

4. speed dies down as a hot topic...

5. scalability is the hot topic (given bitcoin's block size issue)...... BETTER DEVELOP SCALABLE CODE!

....

You can guess what is the next step...

Empty promises:






From the outside looking in it appears that Evan does the following:

1. realizes that anonymity is the hot topic .......BETTER DEVELOP ANONYMOUS CODE!

2. anonymity dies down as a hot topic...make some excuse not to finish it fully

3. speed is now the current hot topic.... BETTER DEVELOP FAST TRANSACTION CODE

4. speed dies down as a hot topic..make some excuse not to finish it fully

5. scalability is the hot topic (given bitcoin's block size issue)...... BETTER DEVELOP SCALABLE CODE!

....

You can guess what is the next step...

In that context it sounds like he is talking about code that someone else wrote.

Perhaps someone that is working behind the scenes.

My guess would be that Evan has people to help him where he doesn't know what he is doing working for him (as he pays them).

Nothing bad about that...just the fact that he makes it appear that HE is the one developing all of this on his own is shady.

not to mention all of the other things like peer review that does not exist for Dash.

The serial number for all coins will be the same.

The pic is just a sample picture. So it won't be #99.

It will be a number below #500.

FTFY

Current high bid ^

This is the winning bid ^

Please send me a Private Message with your shipping information (and selected shipping method) along with how many coins you are going to prefund. I will respond with at total that includes the cost of shipping to pay.

This auction is closed.

Added some images and info to the OP. It's a work in progress.

I looked at your account history...even though it is somewhat inactive/spotty.

I will consider your bid valid.

Shen linked me to the latest version of RingCT paper: https://www.overleaf.com/read/qzgytbyyxvyf

I've created a thread to discuss RingCT in a more simplified (hopefully) context here: https://bitcointalk.org/index.php?topic=1268336.msg13091439#msg13091439

It's a work in progress.

Looks like shen added 10-11 pages of content from the last version which was 15 pages.

Well that goes to show how serious you are about selling something you are listing if you can't even do that.

Why should any one take your post serious?

 

This thread is specifically for discussing Ring Confidential Transactions as defined and outlined in Shen Noether's RingCT pdfs

My Goal of this thread is to simplify RingCT and its definition as much as possible so others can understand it (including myself)

Disclaimer: I am just a curious mind. I do not pretend to know anything about RingCT and its underlying math/proofs/defintions. I am merely a curious soul trying to understand how this all works. I welcome any and all discussion directly related to the topic of this thread. IF I HAVE WRITTEN SOMETHING WRONG OR INCORRECTLY PLEASE POST OR PM ME ABOUT IT SO I CAN CORRECT IT.

Latest version: https://github.com/ShenNoether/MiniNero/raw/master/RingCT0.5_copy.pdf

This paper is very math heavy and some variables are defined and some aren't.

Hopefully after discussion there can be more clarity on the math that is used within.


Preface/Purpose:

Currently in Monero amounts that are transferred are public to view. Ring CT is an attempt to obfuscate the amount of a transaction (and all of its inputs and outputs) to add more transactional privacy.


Definitions:

MLSAG - Multilayered Linkable Spontaneous ad-hoc group signatures

E - an elliptic curve equation; −x² + y² = 1 + dx²y²;

q: a prime number; q = 2²⁵⁵ − 19

d = -121665/121666

P_j = xG = Public Key

G = Ed25519 base point

l: a prime order of the base point; l = 2²⁵² + 27742317777372353535851937790883648493 =~ 7.25 x 10⁷⁵

x = signer's spend key

I = xH(P_j) = Key Image (unique - no copies/duplicates allowed)

H = hash function returning a point (in practice toPoint(Keccak(Pk)))

h = hash function toScalar(Keccak(Pk))  <---- can take multiple parameters concatenated

m = message

α, s_i, i =/= j, i ∈ {1,...,n} are random values in Z_q (the ed25519 base field)
s_j = α − c_j·x mod l
α = s_j +c_j·x mod l

L_j = αG = s_j·G + c_j·P_j <---- Intermediate value if i = s

R_j =αH(P_j) <---- <---- Intermediate value if i = s

c_j+1 = h(m,L_j,R_j) or  A.K.A. "non-interactive challenge"

σ = (I,c₁,s₁,...,s_n) = Signature

Key Vector = the collection of all public keys Y = (y₁,...,y_r) and corresponding private keys X = (x₁, ..., x_r)

Generalized Ring = [P_ij] where i = 1,...,n and j = 1,...,m = n-members and all of which have EXACTLY m-keys




<Other heading not sure what to call it lol>

1. What I've deduced from reading up until page 6 is that the idea of obfuscating amounts will be accomplished with
"mixing" with n signers that have the same amount of m keys.



2. Also noticed that the equations are recursive mod n. If you don't know what that means that means that for example define the following:

L_j = s_j·G + c_j·P_j

c_j+1 =H(m,L_j,R_j)

Since L_j is part of the definition of c_j+1  and c_j is part of the definition of L_j that is the definition of recursion. A function/equation calling itself within its definition.

The mod portion is the remainder of a division (example: 5 mod 3 = 2).

In the context of this paper c_n+1 = c₁ AND c_n+2 = c₂...and so forth, because (n+1) mod n = 1 and (n+2) mod n = 2


s_j = α − c_j·x mod l
α = s_j +c_j·x mod l


3. With a single c_i value, the P_j values, I (key image), and all the s_j values...

... all other c_k values can be deduced while k =/= i.

This provides space saving of about 1/2 the space/size when creating the signature. <------ is this part of Compact CT?

The signature therefore is:

σ = (I,c₁,s₁,...,s_n)


4. Assuming a GENERAL RING composed of n-member and  EXACTLY m-keys with the following requirements:

a. Exactly 1 of the n-signers gives a signature on all m of their keys.

b. If that same user uses any of those m-keys to in another GENERAL RING SIG then, the two RINGS are linked.


<more to come>



Elliptic-curve overview:

Example #1 with d = 30:

x² + y² = 1 - 30x²y²



Center of the curve is point (0,0) for reference.




Example #2 using the actual curve E as defined above:

<-------- Actual Ed25519 curve used in Monero/cryptonote



As you can see above in the blue is the curve of the equation in the image above it. Here is the site where the graph was generated https://www.desmos.com/calculator/ialhd71we3

Just paste the following into a new Elliptic curve line on the left:

Question: Why do you only show the graph from -7.25x10⁷⁵ to 7.25x10⁷⁵ on the x-axis?

Answer: Because l as it is defined 2²⁵² + 27742317777372353535851937790883648493 =~ 7.25 x 10⁷⁵

Because we mod the base point G by l in our computations this why the graph essentially "ends" at those points.





Example #3
Now if you play with some of the values on that site you can get a different modified curve that doesn't just look like two parallel lines just to get a gist of how elliptic curves look like when you slightly modify the values:







Example #3
And modifying it one more time you get:

Will be editing OP to add more information as I am able to digest it in my limited capacity brain.

can anyone guess how many of these "core fundamentals" changed even after Evan claimed it was not going to change?


Then he goes on to say this...

This is a quote from Evan Duffield
"This system doesn't mix on masternodes at all. It's done on a protocol level.
And so, we actually don't like that we are mixing on masternodes and I wanted to remove that for a long time and I finally figured out how to do it."

Oh and how did you come to the conclusion? Proof?

Just "the manipulator"?

Talk to OTOH he knows quite a bit about that. 

This thread was referenced in the followig Ring Confidential Transactions pdf paper by Shen Noether.

The 1/2 size reduction is referenced in the first few pages.

Good stuff.

Thanks Adam!
