You are mixing BASE16 with BASE10 there Cheesy

Your private key = 0x0000000000000000000000000000000000000000000000000000000000000002
It's called BITcoin not BYTEcoin !! or even INTcoin hahaha Roll Eyes

Since this is a tutorial you can not really leave out the part of the binary private key so here goes.

You start with a 256 Bits BASE2 Binary Private Key. (Aka. the BIT coin flips)
A bit is either 1 or 0 no in between.

Code:

1011010000000101011011011111011001101001000111111000110111000111001011100101011000110000001011011101101011010011010001011101011001011111111010101101001111101010110110010010100110010110000010011010100000100110111000100011010001001110101101100011101010100100

Then you can use the following table which is about point doubling:

Code:

256 '1' - represents 1*G or 1 * the generator point
255 '2' - represents 1*G + 1*G or 2 * the generator point
254 '4' - represents 2*G + 2*G or 4 * the generator point
253 '8' - represents 4*G + 4*G or 8 * the generator point and the point doubling goes on 256 times...

The first number in the list is the bit number, and the second number is the multiplier, the number of times you will add the generator point to itself later on.

It's important to know that we start with bit 256, this is the last bit of the binary private key so you have to read the private key backwards and start with the last bit first.

Adding all the numbers is simple:
If the bit value is true or a '1' then you will write down the multiplier value and if it is false or a '0' you will write down nothing and move to the next bit.

You do this for all the bits and when you are done, you simply add all these multiplier values together, and this will give you the number of times you have to add the generator point to itself to get to the public key point.

Code:

1011010000000101011011011111011001101001000111111000110111000111001011100101011000110000001011011101101011010011010001011101011001011111111010101101001111101010110110010010100110010110000010011010100000100110111000100011010001001110101101100011101010100100

We now add up all these numbers, and this gives us a total of privateKeyBase10 = 81425905913881293233417886915456929825803636934140198496261481046664027716260 in BASE10
Or a total of privateKeyBase16 = b4056df6691f8dc72e56302ddad345d65fead3ead9299609a826e2344eb63aa4 in BASE16, which is the hexadecimal private key.

This is the private key number in a format that few people are familiar with but it can also be represented in various WIF Formats depending on the compression parameter:

WIF: 5KBZytdkzttdedEB7xLom6YnHRCVTNQPUrJiTDJKS7VJUbiX6Di // uncompressed
WIF: L3Fea6uFCY2tm4u9fhGRPdVGsToibPUEDvdBxhHSMqdv8odQMTAZ // compressed

As most of us know the full uncompressed public key will start with prefix '04' and have both the X and Y coordinates.
The compressed public key only holds the X coordinate, and it can be odd, or even.
Public keys of the even type start with a prefix '2' while public keys of the odd type start with a prefix '03'
You can discover, or calculate the key type of the compressed public key by looking at the least significant bit of the Y coordinate of the public key.

It's important to note that this is not regular multiplication but epileptic curve multiplication.

That's what I wanted! Could you make private key 3?

We must not forget that there are two formulas
The one you used to find the point corresponding to the private key: 2 (or rather 0000000000000000000000000000000000000000000000000000000000000002 to be more precise) it is Duplication of points.
You did it in your example with the base point--> 1 + 1 =2 (but that could be another point)
To go now with 3 we need to do --> 2 + 1 = 3 (we have now 2 différents points and we can't doubling them)

For that you need to use the second formula:

modulo = 115792089237316195423570985008687907853269984665640564039457584007908834671663
Px = 89565891926547004231252920425935692360644145829622209833684329913297188986597 (x coordinate point 2)
Py = 12158399299693830322967808612713398636155367887041628176798871954788371653930 (y coordinate point 2)
Qx = 55066263022277343669578718895168534326250603453777594175500187360389116729240 (x coordinate point 1) not because it is the base point, just because it is the point n°1
Qy = 32670510020758816978083085130507043184471273380659243275938904335757337482424 (y coordinate point 1)

dx = (Qx - Px) % modulo --> 34499628904269660561674201530767158034393542375844615658184142552908072257357
dy = (Qy - Py) % modulo --> 95279978516251208768455708490894263304954079172022948940317551626939868843169
c = dy * invert(dx) % modulo --> 23578750110654438173404407907450265080473019639451825850605815020978465167024
Rx = (c*c - Px - Qx) % modulo --> 112711660439710606056748659173929673102114977341539408544630613555209775888121 (x coordinate of point (2+1 =3)
Ry = (c*(Px - Rx) - Py) % modulo --> 25583027980570883691656905877401976406448868254816295069919888960541586679410 (y coordinate of point (2+1 =3)

Can't explain better

If the formula is always the same, All public keys will also always be the same! "Where am I wrong?

(dx, dy, c, R.x, R.y, Q.x Q.y, P.x, P.y)Can someone explain to me what are this?

I think Rx and Ry are the coordinates of the public key, right?

ok, I will try to explain as simply as possible because it is true that I myself struggled to understand the system.
So it is a question here of adding 2 points (not the same). In this example we use :

first point: (all values are in décimal for a better comprehension)

X coordinate: 21262057306151627953595685090280431278183829487175876377991189246716355947009 (it is Qx)
Y coordinate: 41749993296225487051377864631615517161996906063147759678534462689479575333124 (it is Qy)
The Private key for this point is 0000000000000000000000000000000000000000000000000000000000000008

second point to add:

X coordinate: 89565891926547004231252920425935692360644145829622209833684329913297188986597 (it is Px)
Y coordinate: 12158399299693830322967808612713398636155367887041628176798871954788371653930 (it is Py)
The Private key for this point is 0000000000000000000000000000000000000000000000000000000000000002

So to add the 1st point to the second we use the formula : (here modulo is 115792089237316195423570985008687907853269984665640564039457584007908834671663 )

dx = (Q.x - P.x) % modulo
dy = (Q.y - P.y) % modulo
c = dy * invert(dx) % modulo
R.x = (c*c - P.x - Q.x) % modulo
R.y = (c*(P.x - R.x) - P.y) % modulo

in our example we have

dx = (21262057306151627953595685090280431278183829487175876377991189246716355947009 - 89565891926547004231252920425935692360644145829622209833684329913297188986597) % modulo
dx = 47488254616920819145913749673032646770809668323194230583764443341328001632075

dy = (41749993296225487051377864631615517161996906063147759678534462689479575333124 - 12158399299693830322967808612713398636155367887041628176798871954788371653930) % modulo
dy = 29591593996531656728410056018902118525841538176106131501735590734691203679194

invert of dx = 70279122268919195963430815486314537773961171454828771794853116552210630553734

c = dy * invert(dx) % modulo
c = 16132032934385503768504319366562120314980927452732756733183380715276156205226

So the new point (8 + 2)

R.x = (c*c - P.x - Q.x) % modulo
R.x --> X coordinate of (8+2) = 72488970228380509287422715226575535698893157273063074627791787432852706183111

R.y = (c*(P.x - R.x) - P.y) % modulo
R.y --> Y coordinate of (8+2) = 62070622898698443831883535403436258712770888294397026493185421712108624767191

If we check these coordinates, we find that it corresponds to the private key: 000000000000000000000000000000000000000000000000000000000000000a (10)

If the formula is always the same, All public keys will also always be the same! "Where am I wrong?

(dx, dy, c, R.x, R.y, Q.x Q.y, P.x, P.y)Can someone explain to me what are this?

I think Rx and Ry are the coordinates of the public key, right?

[/quote]

ok, I will try to explain as simply as possible because it is true that I myself struggled to understand the system.
So it is a question here of adding 2 points (not the same). In this example we use :

first point: (all values are in décimal for a better comprehension)

X coordinate: 21262057306151627953595685090280431278183829487175876377991189246716355947009 (it is Qx)
Y coordinate: 41749993296225487051377864631615517161996906063147759678534462689479575333124 (it is Qy)
The Private key for this point is 0000000000000000000000000000000000000000000000000000000000000008

second point to add:

X coordinate: 89565891926547004231252920425935692360644145829622209833684329913297188986597 (it is Px)
Y coordinate: 12158399299693830322967808612713398636155367887041628176798871954788371653930 (it is Py)
The Private key for this point is 0000000000000000000000000000000000000000000000000000000000000002

So to add the 1st point to the second we use the formula : (here modulo is 115792089237316195423570985008687907853269984665640564039457584007908834671663 )

dx = (Q.x - P.x) % modulo
dy = (Q.y - P.y) % modulo
c = dy * invert(dx) % modulo
R.x = (c*c - P.x - Q.x) % modulo
R.y = (c*(P.x - R.x) - P.y) % modulo

in our example we have

dx = (21262057306151627953595685090280431278183829487175876377991189246716355947009 - 89565891926547004231252920425935692360644145829622209833684329913297188986597) % modulo
dx = 47488254616920819145913749673032646770809668323194230583764443341328001632075

dy = (41749993296225487051377864631615517161996906063147759678534462689479575333124 - 12158399299693830322967808612713398636155367887041628176798871954788371653930) % modulo
dy = 29591593996531656728410056018902118525841538176106131501735590734691203679194

invert of dx = 70279122268919195963430815486314537773961171454828771794853116552210630553734

c = dy * invert(dx) % modulo
c = 16132032934385503768504319366562120314980927452732756733183380715276156205226

So the new point (8 + 2)

R.x = (c*c - P.x - Q.x) % modulo
R.x --> X coordinate of (8+2) = 72488970228380509287422715226575535698893157273063074627791787432852706183111

R.y = (c*(P.x - R.x) - P.y) % modulo
R.y --> Y coordinate of (8+2) = 62070622898698443831883535403436258712770888294397026493185421712108624767191

If we check these coordinates, we find that it corresponds to the private key: 000000000000000000000000000000000000000000000000000000000000000a (10)

they aren't the same because this formula is called different number of times depending on the private key. in simple terms imagine if the formula was this: x+1 and you always called it with the same x (like you do with the generator point). if you use it with x=5 and call it 3 times (private key equal to 3) you get 8 and if you call it 6 times (private key equal to 6) you get 11 and so on.

I have a question.
If the private key is 3 ... do I need to change the formula this way?
R = P+P+P
c = 4*P.x*Px*invert(3*P.y) % modulo
R.x = (c*c - 3*P.x) % modulo

No, formula is ALWAYS the same. That was a formula for double the point:
c = 3*P.x*Px*invert(2*P.y) % modulo
R.x = (c*c - 2*P.x) % modulo
R.y = (c*(P.x - R.x) - P.y) % modulo

If you want to add 2 points P and Q (2 different non-zero Points) there is another formula for R = P + Q:
dx = (Q.x - P.x) % modulo
dy = (Q.y - P.y) % modulo
c = dy * invert(dx) % modulo
R.x = (c*c - P.x - Q.x) % modulo
R.y = (c*(P.x - R.x) - P.y) % modulo

If the formula is always the same, All public keys will also always be the same! "Where am I wrong?

there is no special formula for point subtraction as far as i know. instead the P-Q is simply defined as P+(-Q) (same as addition) and -Q or negative of a point is defined as negating its y coordinate. or in other words -Q(x,y) = Q(x,-y) and since we don't use negative numbers in modular arithmetic -y becomes P-y where P is curve's prime.

oOO !! wonderfully explained, first test -> total success .. I understood the first time when research for several weeks had not led to much.
Many thanks to you BrewMaster (again ^^)
It is this notation (-y becomes P-y where P is curve's prime) that I have not seen anywhere that I am lacking.

Hello everyone, good! thanks to the help of MrFreeDragon and BrewMaster I now have a good basis for adding 2 points on an elliptical curve.

As a reminder :

If you want to double point P in order to receive R = P + P, you should make the following:
c = 3 * P.x * Px * invert (2 * P.y)% modulo
R.x = (c * c - 2 * P.x)% modulo
R.y = (c * (P.x - R.x) - P.y)% modulo
modulo = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F
and
If you want to add 2 points P and Q (2 different non-zero Points) there is another formula for R = P + Q:
dx = (Q.x - P.x)% modulo
dy = (Q.y - P.y)% modulo
c = dy * invert (dx)% modulo
R.x = (c * c - P.x - Q.x)% modulo
R.y = (c * (P.x - R.x) - P.y)% modulo

I have now no problem with this but as you can imagine, I still have 1 problem ^^, certainly due to my approximate understanding of English I am unable to find a formula for point to point substraction. Is this also possible?

Thanks in advance (again^^)

My question is : why 13 = 8 + 4 +1 ? is 4 + 4 + 4 + 1 give the same result or must there be a certain rule ?
Not sure and i can't retreive the post but it seem i read something with the private key in it's binary form ?
-snip-

Your example with 13 will give the same result. You can also calculate 13 as 1 + 1 + 1 + 1 + ... + 1 + 1 (13 times), but here you should perform 12 additions.

As for the private key in binary form - I made a tool to play with binary numbers: https://bitcointalksearch.org/topic/bitcoin-visual-private-key-generator-5187401
That tool is very nice for learning purposes. And also good to create real wallets if you use physical coin for your random entropy source.

Every binary number could be represented as c255*2^255 + c254*2^254 + c253*2^253 + ... + c3*2^3 + c2^2 + c1*2 + c0, where coefficients c0, c1, c2, ... c254, c255 represent bit values (1 or 0). It is actually your binary number.
So in order to calculate public keys for various large binary numbers you can easily make the pre-calculations of 256 public keys for numbers 1, 2, 2^2, 2^3, 2^4, 2^5, ... 2^254, 2^255 and later just make up to 255 additions between pre-calculated public keys.

that's the idea. one of the methods to compute public key (which is multiplying the key numeric value by generator point) is that key (shown as d) is going to be split into smaller powers of 2 parts (d0 + 2d1+...) then for each 1 an addition then a doubling occurs and for each 0 only point double is performed.

Thanks to MrFreedragon and BrewMaster for the explanations. However I still have a question on the generation of public key with a private key other than 1 or 2 or 13 like the examples.

MrFreedragon say :
"The same for every number. For example, if you want to find the public key for 13, you should present it in this form: 13 = 8 + 4 + 1 = 2^3 + 2^2 + 1, and now calculate public key for every part (for 2^2 it is doubling G, and then doubling te received result again; for 2^3 it is the dubling G 3 times, anf for 1 it is just G); as soon as you have all 3 public keys you should use addition formula 2 times: add 2^3 and 2^2 and then add the received result with G. Finally you will have the public key for pk = 13"

My question is : why 13 = 8 + 4 +1 ? is 4 + 4 + 4 + 1 give the same result or must there be a certain rule ?
Not sure and i can't retreive the post but it seem i read something with the private key in it's binary form ?

I'm confuse with this part : c = 3*P.x*Px*invert(2*P.y) % modulo
How get invert(2*P.y) = 0xb7e31a064ed74d314de79011c5f0a46ac155602353dc3d340fbeaeec9767a6a6 ??

As was explained above, the inverse for k by modulo is such value mwhere (m*k) by modulo is equal to 1.
The best way for python is to use library gmpy2 and its function gmpy2.invert(k,p) which returns the inverse value to k by modulo = p. This function is the best for python and approx. 50 times faster than any other self made calculations.

For ubuntu for example you can easily install it:

Code:

sudo apt update
sudo apt install python3-gmpy2

If it is not in repository, you can download gmpy2 from here (pls, check the correct python version): https://www.lfd.uci.edu/~gohlke/pythonlibs/#gmpy

and install it in this way (example for python ver 3.7):

Code:

python -m pip install gmpy2-2.0.8-cp37-cp37m-win_amd64.whl

If you do not want to use the gmpy2 libriary (however it is the best way), you can also use this self made inversion function:

Code:

def egcd (a, b):
   if a == 0:
   return (b, 0, 1)
   else:
   g, x, y = egcd(b % a, a)
   return (g, y - (b // a) * x, x)

def inversion (m, n):
   while m < 0:
   m += n
   g, x, _ = egcd (m, n)
   if g == 1:
   return x % n
else: print (' no inverse exist')

The function inversion requires 2 parameters: m and n, where n is the modulo and m is the number for which you would like to calculate the inverse.

How get invert(2*P.y) =

the full name is Modular Multiplicative Inverse and to compute ModInverse(2*P.y) you have to find a value that when multiplied by your value and divided by the prime gives 1.
you can read more about it on wikipedia:
https://en.wikipedia.org/wiki/Modular_multiplicative_inverse
look at the examples below that.
the computation uses the extended Euclidean algorithm.

Thanks for the answer. I will correct my question.
I just wanted to understand the G + G2 point duplication part ... The public key of 2,
X =0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798.
But for me:
X = 02f37cccfdf3b97758ab40c52b9d0e160e0537f9b65b9c51b2b3e502b62df02f30

If you want to doule point P in order to receive R = P + P, you should make the following:

c = 3*P.x*Px*invert(2*P.y) % modulo
R.x = (c*c - 2*P.x) % modulo
R.y = (c*(P.x - R.x) - P.y) % modulo

modulo = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F

For your case with P = G = Point (Gx, Gy) where:
Gx = 0x79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798
Gy = 0x483ada7726a3c4655da4fbfc0e1108a8fd17b448a68554199c47d08ffb10d4b8

We have the following:
invert(2*P.y) = 0xb7e31a064ed74d314de79011c5f0a46ac155602353dc3d340fbeaeec9767a6a6

R.x = (c*c - 2*Gx) % modulo = 0xc6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5
R.y = 0x1ae168fea63dc339a3c58419466ceaeef7f632653266d0e1236431a950cfe52a

So we have R.x and R.y of the public key 2G = G + G (public key for private key = 2), and it is written in compressed format like:
02c6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5

Hello,

Thanks for your explanation

I'm confuse with this part : c = 3*P.x*Px*invert(2*P.y) % modulo
How get invert(2*P.y) = 0xb7e31a064ed74d314de79011c5f0a46ac155602353dc3d340fbeaeec9767a6a6 ??
Can someone provide an explanation or simply a python formula, is it the inverse modular ?

Thanks in advance

I just want to understand the math behind Bitcoin in a simple way Wink

you can check this sources to learn more. I am also a learner and happy to be here.

For more details have a look at parrt 4 of this reading:

Thanks both of you for sharing this sources. I am also still learning this and happy to get in touch of you guys. Personally, i do bounty to earn something while i am learning this. But my curiosity take me into this forum while i just start leaning python and other programming language. Cheesy

well that math is not very simple to learn it that easily. there is a lot of new concepts involved and the whole algorithm (elliptic curve cryptography) also has certain complexity to it.
but i have found that this page here explains things in simpler terms that could get you started on understanding the whole thing, specially while looking at the curve shapes included helps with understanding the characteristics of elliptic curves:

Wait a minute, so are you guys suggesting that you can actually calculate or deduce the private keys of someone by just looking at the public key? I'm lost maybe a bit of clarification would help. Or I am not getting that the OP is trying to say.

No that's not actually going to happen. Because this is just one integer public key, but in reality there are more integer in your private key. No scripts can deduce the private keys of someone. Even if anyone wants to do this, he/she needs a quantum computer with a minimum of 1000 qubits to expose any private key from any algorithm. In this current time, only IBM has 50 qubits of a quantum computer and Google (cooperating with NASA) has 53 qubits of quantum computer. Thought D-wave have 2000 qubits of quantum computer, but that's used only for optimization not for general purpose. So, it's will take more time to break bitcoin or other crypto-currencies private key. Also by the time passed, there will be a solution for it too. Cheesy

I agree with you!
