I have a question and why two different private keys can lead to the same address in certain circumstances?
Example:000000000000000000000000000000000000000000000050574a424748444e47
fffffffffffffffffffffffffffffffebaaedce6af48a08c171ca0d4187a8f88
1ECDtqs8nAUyxNuTY4kTV6rHr6NoVUkMna

s= fffffffffffffffffffffffffffffffebaaedce6af48a08c171ca0d4187a8f88
N = 115792089237316195423570985008687907852837564279074904382605163141518161494337

because s being larger than the order of the curve N they are equivalent to the same private key.

r= fffffffffffffffffffffffffffffffebaaedce6af48a08c171ca0d4187a8f88 % N

r= 000000000000000000000000000000000000000000000050574a424748444e47

r = s

"In response to your question, I have conducted studies on the elliptic curve that allow me to simplify some key encryption calculations. One of these is the calculation of the compressed address of the private key. To compute this, we first determine the decimal representation of the key and then multiply the result by 256. This gives us the decimal number of the private key for the compressed address we are looking for."
