* @brief a 160 bit hash of a public key
*
* An address can be converted to or from a base58 string with 32 bit checksum.
*
* An address is calculated as ripemd160( sha512( compressed_ecc_public_key ) )
*
* When converted to a string, checksum calculated as the first 4 bytes ripemd160( address ) is
* appended to the binary address before converting to base58.
