all points with lowest Y-coordinate are odd and with highest are even. and if we could calculate exact position of point in this group there could be a correlation
to secp256k1 subgroup S={G,2G,3G,...,(N-1)G}.
but secp256k1 P-N is 432420386565659656852420866390673177326 more than 2^128 since not all values of P can become X-coordinate.
The last part effectively rules out dividing the Y by 2 and discarding the fractional part, to attempt to discern the subranges of X (e.g. between 0,2^64-1 and 2^64,2^128-1)
hi is there any way to find private key range using public key
pk1 = '022f8bde4d1a07209355b4a7250a5c5128e88b84bddc619ab7cba8d569b240efe4'
pk2 = '02C6047F9441ED7D6D3045406E95C07CD85C778E4B8CEF3CA7ABAC09B95C709EE5'
pk1<=pk2
false
any python code useful for me
im getting below error
typeerror ' ' not supported between instances of 'point' and 'point'
Are you sure you are using this code smapl, because this error message looks funny - there are no point types in this code.
