<P>
A BitCoin address is fundamentally derived from an elliptic curve public key and a set of network parameters.
It has several possible representations:<p>
<ol>
<li>The raw public key bytes themselves.
<li>RIPEMD160 hash of the public key bytes.
<li>A base58 encoded "human form" that includes a version and check code, to guard against typos.
</ol><p>
One may question whether the base58 form is really an improvement over the hash160 form, given
they are both very unfriendly for typists. More useful representations might include qrcodes
and identicons.<p>
Note that an address is specific to a network because the first byte is a discriminator value.
