Topic: Any particular meaning to this? K=z/s and R=X (Read 361 times)

How is that relevant?  X is what you want to establish in the end .. so if R = X then i would presume that is applicable as its established form K

This is just a way i was playing around with .. more so i outlined what i was doing with

proving
S = ((Z + (X * R)) / K) % N
R = (((S * K) - Z) / X) % N
Z = ((S * K) - (X * R)) % N
X = (((S * K) - Z) / R) % N
K = ((Z + (X * R)) / S) % N

So where is the error in that? i dont see one...

In a ECDSA process the R value is always equals to the X value of the result of multiply your random nonce K by the generator point.

This is

Publickey = k*G

R = Publickey.X

You can check the full process in: https://cryptobook.nakov.com/digital-signatures/ecdsa-sign-verify-messages

In your examples none of the K values generate those X or R values that your are showing, that's means that you are doing something wrong or your scripts are doing something weird, so any extra calculations with your current ""K"" value will be wrong, maybe you are skipping some steps or maybe you are confused about what you are doing.

But without any extra information we can't help.

What calculator do you use?

in ECDSA

if :
K =0xdec38117d66f305ea76ee63b625c283d37b2bb144ad96c269ea72bce06b3e702

restult :
R=0x6f543f42b9a91e55e2eaabf3d52cbfe4555d3ef39248f1cbcbc6cbf5b1ad74e6

Why would sharing the code provide any insight? Its just self generated RSZK points based on the public key ...
Im asking about the correlation K=z/s .... which i dont see in this manner referenced and repeats..  
Any significance?  Can do it on other addresses




or on another code i get R=X  which was surprising...

R = 0x17fc8af742cd78a73d7d720700fb7b1c21c15ea0b3ea07911781ca0f6a1a9f03
S = 0xbc87bcbb1e1f34b673e28c4b31168f03ab13fdadf7bf8330acc160d304740818
Z = 0x6951c1defa7011c72c990168ec9dc2540a7cb09d681e28643ea8d3a41cac7e73
K = 0xdec38117d66f305ea76ee63b625c283d37b2bb144ad96c269ea72bce06b3e702
X = 0x17fc8af742cd78a73d7d720700fb7b1c21c15ea0b3ea07911781ca0f6a1a9f03

Where as: with R you can verify you have the correct K value, and if you have the correct K value, then you can get the correct X value...
So R=X would be relevant?

proving
S = ((Z + (X * R)) / K) % N
R = (((S * K) - Z) / X) % N
Z = ((S * K) - (X * R)) % N
X = (((S * K) - Z) / R) % N
K = ((Z + (X * R)) / S) % N



I am not sure about legitimacy on either k=z/s or r=x   --- not a phd in math or anything hence why i am asking.  lol

Not really sure. Share your codes for us to understand further.

Your Random K Value *G != R
K =  6ec4814e7f2a2443682a4ab10414ceb588450c78edacd8d88e8b33a449549141 255 bits

Your code share please..

Just wondering if this has any particular meaning when k=s/z ..
