Should i ignore a as given by ncsupanda. I don't think that ignoring 'a' is right.
Mathematically as long as the "a" value remains constant during each new iteration then the effect it has is constant - it's not unnecessary, it just doesn't need to be evaluated for, so it should be fine to set as any integer and leave it alone.

Also, is this the right formula? If so, A=a?

I think 'a' is an arbitrary constant provided by Evil-Knievel
From the problem description "Being a some constant," I think is meant to be interpreted as
Code:
'a' being some constant

How often do you have to perform this operation to get a specific x (basically getting the new_x and feeding it back into the formula to get another new_x, and so on)?

that is the exact operation I did. So I was not wrong?

Here's my thinking on the question...


x_0 is always 9
a is an arbitrary constant
G is the end goal, also an arbitrary number chosen by Evil-Knievel
_i is the number of steps through the recursive function you must take to reach G

Evil-Knievel is looking for a way to solve '_i' provided any 'a' and any 'G'


EDIT: That's not just standard division, it's as he mentioned using inverse modular multiplication, but visually it's depicted as division.

Was just reading more on the Montgomery curve under the arithmetic section, I think we are safe to "ignore" z, him saying z=1 allows us to say X=x and that's all we need the z for.


Code:
A point P=(x,y) on the elliptic curve in the Montgomery form By^2 = x^3 + Ax^2 + x can be represented in Montgomery coordinates P=(X:Z), where P=(X:Z) are projective coordinates and x=X/Z for Z!=0

You can start multiple such chains beginning at x=9, and add the resulting x values
using the addition algorithm from http://en.wikipedia.org/wiki/Montgomery_curve (Montgomery arithmetic section).
Note, that the x value, is the value you get at the end of such calculation-chain, and the z value is always 1.

wHat is meant by multiple chains? aand where is this 'z'?

I don't know what he is referring to by 'multiple chains'


Another user suggested 'z' might be Standard_Score/Standard_Deviation although I don't think that is correct

i had a different assumption about faucets and this has clearly not lived up to my expectations

Would you mind sharing what those expectations/assumptions were?

No, I am substituting the equation back into itself. Please check if I was wrong.

Are you using standard division where the / is or are you using "multiplication by the modular inverse"
http://cs.brown.edu/courses/cs007/modmult/node2.html


Should we be knowing what 'p' is or is this another arbitrary number like 'a'?
(basically all operations modulo some sumber p)

But is there any way I request a MOD's of the forum to remove the negative trust given to me by this fucking scamer ?

The mods will not remove it, however it shows under untrusted and people tend to ignore negative feedback left by scammers.

You still show as "Trust: 0: -0 / +0(0) " so don't worry too much about invalid feedback

Evil-Knievel is this algorithm related to your project over at https://bitcointalk.org/index.php?topic=929196.0 ?

I was looking at curve25519 and notice that it's starting parameter is x=9


I read that, but what is 'a' exactly? If it is an unknown constant, then how will I find when the said result will occur. Is it 1? Or does the value of a has no impact on the result (but it certainly does)? Or on calculation the value of 'a' will be given?

I think I did not understand the question properly. Huh

That I cannot answer. I'm currently doing some reading on the curves and trying to see what I can get out of it. (so far not much Wink)

Seems like someone found a solution, https://blockchain.info/address/18b2no9rBkovhv5gf3vkd5VQ9MKxHvqSzu

the money is not there anymore.
Has the winner been found or you are still looking for an answer?
Please update the OP. And if the bounty is still on then where are the coins?

2 posts below that I offer insight into how that happened: https://bitcointalk.org/index.php?topic=939215.msg10317539#msg10317539

Also, that transaction happened less than 24 hours ago during which time OP hasn't even logged into the forums yet.



Spam your signature somewhere else.

What is a?


What is a? What is z? Is both user defined?

a and z are constant of the Montgomery curve algorithm (http://en.wikipedia.org/wiki/Montgomery_curve)

the z value is always 1.

1373  Economy / Services / Re: Request: mobile cellphone tracking service on: January 31, 2015, 10:54:21 AM

sorry to break the bad news but u r doomed in this case. Every "service" of that kind in europe requieres and "sms text message" approval. That means in order to track the phone (has to have gps) , to send the text and then the other person has to confirm that she wants to be tracked , very poplular service in my country to track your kids (in this case you program it yourself)


Where can I find this?

I really need it. Cool

Not quite the way he described it but a good app to track family on smartphones is Life360 (https://www.life360.com/)

Seems like someone found a solution, https://blockchain.info/address/18b2no9rBkovhv5gf3vkd5VQ9MKxHvqSzu

the money is not there anymore.

The funds from that address got used to fund another of his projects it seems, he likely just used Armory and it chose those coins to send because they are all in his wallet. I'd be willing to bet this bounty is still open as Evil-Knievel has much more in his wallet than just that.

1PayC5RCF2aXZ6Rjg2DpVM73gaQbndiZVX is the payout address for his "nxt-miner"

The fifth last option you are searching for is short a hex char (7 instead of Cool

Code:
a==0xe239bdb

Should that be a trailing 0, leading 0, or did you goof in the copy/paste?

It's not really what you're looking for, but...

If they can read your plain text rpc password from the config file on the server, your bitcoins are already gone because they likely got the wallet.dat file. (Unless that's encrypted but seeing as how they are on the server now they should be able to lurk in the shadows until it's decrypted)

79$ is price for single 8GB DDR3 RAM or for all those 4x8GB RAMs, are you willing to ship them to Asia

I'd assume that's the price per stick
