As you might remember the public key is some point X Y on the curve. This means that it is a set of x and y coordinates which satisfy the elliptic curve equation. However the Bitcoin curve has a neat property that any X coordinate can only ever have one of two Y coordinates and the Y coordinates can be derived from the X coordinate. The only way our Public Key therefore our Bitcoin can be comprised is by revealing our Private Key. As you might remember the public key is some point X Y on the curve.
Bitcoin Public Key X Y. Instead lets keep X and the sign of Y. Thats your public key. Using public-key cryptography you can sign data with your private key and anyone who knows your public key can verify that the signature is valid. As you might remember the public key is some point X Y on the curve.

If i can get a code example in php it would be more helpful for me. Later we can derive Y from that if needed. A private key is always mathematically related to the bitcoin wallet address. Our public key thus corresponds to the point 52 7. The only way our Public Key therefore our Bitcoin can be comprised is by revealing our Private Key. However the Bitcoin curve has a neat property that any X coordinate can only ever have one of two Y coordinates and the Y coordinates can be derived from the X coordinate.
All that work for a private key of 2.

Instead lets keep X and the sign of Y. We know the curve and for each X there are only two Ys that define the point which lies on that curve. In this uncompressed format you just place the x and y coordinate next to each other then prefix the whole thing with an 04 to show that it is an uncompressed public key. So whereas an original public key will begin with 04 a compressed public key will begin with either 02 or 03. There is more to a bitcoin wallet than just the address itself.

When a user initiates his or her first transaction with bitcoin or altcoins a unique pair of a public key and a private key is created. A private key which is just a number such as 42 can be transformed mathematically into a public key.
