Public key type:

calculate public key

1- Public ECDSA Key (aka Bitcoin public key): (copmpressed public keys must be 33byte and start with 02 or 03)
(uncopmpressed public keys must be 65byte and start with 04)
sha-256(public key)

2- SHA-256 hash of 1: ripemd160(this)

3- RIPEMD-160 hash of 2: add network byte

4- Adding network byte to 3 (bitcoin mainnet is 00): calculate checksum

checksum calculation
5- SHA-256 hash of 4: 6- SHA-256 hash of 5: 7- First four bytes of 6 (this is checksum):

8- Adding 7 at the end of 4: base58 encode(this)

9- Base58 encoding of 8 (aka bitcoin address):
