So is there any way to derive or calculate the number representation from btc address that coresponds to its private key hex?
Please clarify whether I am understanding your question correctly. Do you want to know if the following equation has a solution?
It could have, as no theory that I am aware of can demonstrate that it has no solution. It goes without saying that until you break the hash function, you cannot find the answer.
No, i was asking if theres any kind of way to derive or get a decimal representation of btc address that coresponds to its private key hex, without having to derive private key hex from btc address first, since decimal and private key hex have nearest relationship dec to hex/hex to dec, so only publicly available components are ripemd160 or btc address to get busy with.. .
Its known that private key wif are derived from private key hex and private key hex is derived from 256bit random number which is from 1 to 115792089237316195423570985008687907852837564279074904382605163141518161494336, in ECDSA it all starts from these natural numbers which is the root of all.
