As seen in our guides to elliptic curve cryptography and how to create a Bitcoin Private key — a public key is in fact just coordinates on the Bitcoin curve calculated through multiplying the generator point by the private key number.

These numbers are shown in Hexadecimal format, or binary digits shown as 64 hexadecimal digits. If the number was shown in decimal format it would be 10 77 figures long. If you take these two coordinates and concatenate them i. There is also the checksum to add which is essentially a hash of the address of the hash of the address — this is to check that the address is what it is — to stop typos et al.

The last step is to change the coding structure into a more readable format or Base58 in the case of Bitcoin. Base 58 is similar to base 64 but with a few characters removed. All the symbols that could be confused for each other are removed making the format readable. The end result is a Bitcoin address of between 27 and 34 characters long! Such as below. Notice that this address begins with 1 meaning it is a Bitcoin main network address and also that the first three characters spell the word Bit — in other words this is a vanity address.
