This will give you a Public Key Hash which should be 20 bytes ie. The only way our Public Key therefore our Bitcoin can be comprised is by revealing our Private Key. An Ethereum public key is a point on the elliptic curve. A Bitcoin address is a 160-bit hash of the public portion of a publicprivate ECDSA keypair. This article may be too technical for some users. One approach appends the y-coordinate to the x-coordinate.
If i can get a code example in php it would be more helpful for me.
The more basic article on Bitcoin Addresses may be more appropriate. They are produced from the private key. Our directory contains all possible Elliptic Curve Digital Signature Algorithm ECDSA secp256k1 private keys in decimal hexadecimal raw and WIF formats. Lets do an Experiment. 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. As you might remember the public key is some point X Y on the curve.

How a Public Key Works. Public Keys are x y points on an Elliptic Curve. In the case of bitcoin. In bitcoin the even or odd part is shown by prepending a number to the x co-ordinate. 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.

Lets do an Experiment. How i can get Bitcoin Address from a Bitcoin Private Key. The result is a Bitcoin full public key. 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. 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.

This means that it is a set of x and y coordinates which satisfy the elliptic curve equation. It also contains the public and private key for each of your bitcoin addresses. A private key which is just a number such as 42 can be transformed mathematically into a public key. Instead lets keep X and the sign of Y. The equation you want for this part begins like this.
