In bitcoin the even or odd part is shown by prepending a number to the x co-ordinate. I understand the whole method except the first one where the public key and its x and y cord comes from the hashprivate key.
Bitcoin Public Key X Y. In bitcoin the even or odd part is shown by prepending a number to the x co-ordinate. Instead lets keep X and the sign of Y. The result is a Bitcoin full public key. Later we can derive Y from that if needed.

There is more to a bitcoin wallet than just the address itself. So instead of having to store both x and y as the public key you can just store x and whether y is even or odd.
Public Keys are x y points on an Elliptic Curve.
A compressed public key uses only the x-coordinate with a symmetry flag. This technique produces an uncompressed public key. Our public key thus corresponds to the point 52 7. A compressed public key uses only the x-coordinate with a symmetry flag. There is more to a bitcoin wallet than just the address itself. As you might remember the public key is some point X Y on the curve.
