Lets do an Experiment. The public key is composed by 2 numbers joined. The Bitcoin curve is Y2 X3 7. 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. The result is a Bitcoin full public key.
Bitcoin Public Key X Y. 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. So whereas an original public key will begin with 04 a compressed public key will begin with either 02 or 03. Public Keys are x y points on an Elliptic Curve.

The public key is composed by 2 numbers joined. Public Keys are x y points on an Elliptic Curve. As you might remember the public key is some point X Y on the curve. Bitcoin originally used both the x and y coordinate to store the public key. Your bitcoin private key is a randomly generated string numbers and letters allowing bitcoins to be spent. An Ethereum public key is a point on the elliptic curve.
Y 2 x 3 7.
One approach appends the y-coordinate to the x-coordinate. Your next step is to turn that into a bitcoin address. So whereas an original public key will begin with 04 a compressed public key will begin with either 02 or 03. The more basic article on Bitcoin Addresses may be more appropriate. Bitcoin originally used both the x and y coordinate to store the public key. For calculating the public key the elliptic curve aritmetic is necessary.

This will give you a Public Key Hash which should be 20 bytes ie. As you might remember the public key is some point X Y on the curve. 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. Y 2 x 3 7. This technique produces an uncompressed 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. The only way our Public Key therefore our Bitcoin can be comprised is by revealing our Private Key. So whereas an original public key will begin with 04 a compressed public key will begin with either 02 or 03. The public key is composed by 2 numbers joined. 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.

This will give you a Public Key Hash which should be 20 bytes ie. The result is a Bitcoin full public key. 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. Our directory contains all possible Elliptic Curve Digital Signature Algorithm ECDSA secp256k1 private keys in decimal hexadecimal raw and WIF formats.
