From what I understood that we have a private and public key correspond to a point on the secp256k1 curve.
We have the option to choose the private key and then derive the public key from that private key.
address is derived from the public key by performing a ripemd160 hash.

address is derived from the public key by performing a ripemd160 hash.
1) Hash it using SHA256 once
2) Hash it using RIPEMD-160
3) Put the version byte at the front
4) SHA256 hash it twice
5) You'll be able to extract the checksum from the first few bytes
6) Insert the SHA256 hash at the end of the RIPEMD160 with version byte and BASE58 encode it.
Blockchain does not verify addresses, so if we mistake it for the right address, we will lose our money.
Every address comes with a checksum. If you accidentally capitalise a character in the address, it'll not be valid.Now suppose I choose a 99 random bytes to generate the private key, it is not a perfect idea but I want to know. How is the addreess, public and private key generated?
As long as your 99 random bytes is within the range of acceptable values for an ECDSA private key, it's alright.Let's take it as 01.
Your ECDSA private key is 01
From there, we'll convert it to an ECDSA public key by multiplying it against the generator point. The number of times the number gets multiplied against the generator point is dependent on the number of your private key which is once.
I thus obtain the ECDSA public key to be 0479BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798483ADA7726A3C 4655DA4FBFC0E1108A8FD17B448A68554199C47D08FFB10D4B8.
After this, I'll do my steps 1 to 6.
1) SHA256 Hash of my ECDSA Public key
50929B74C1A04954B78B4B6035E97A5E078A5A0F28EC96D547BFEE9ACE803AC0
2) RIPEMD160 Hash of the above
50929B74C1A04954B78B4B6035E97A5E078A5A0F28EC96D547BFEE9ACE803AC0
3) Apprehending the network byte to the front (for P2PKH addresses on Bitcoin mainnet, it is 00)
0091B24BF9F5288532960AC687ABB035127B1D28A5
4) SHA256 the above
79FA926BF4AC874060B244D6E985C694233EED0D5562C0B88CDF37BFBB80B44F
5) SHA256 the above
0074FFE0526D823BE09B39865422A1D6135AFC85AFB0A6863C58E9FE89989170
6) Take the first 4 bytes as our checksum
0074FFE0
7) Apprehend the checksum to the end of the SHA256 hash
0091B24BF9F5288532960AC687ABB035127B1D28A50074FFE0
