+===Extended Key Version===
+
+When serializing extended keys, this scheme uses alternate version bytes. Extended public keys use <code>0x04b24746</code> to produce a "zpub" prefix, and private keys use <code>0x04b2430c</code> to produce a "zprv" prefix. Testnet uses <code>0x045f1cf6</code> "vpub" and <code>0x045f18bc</code> "vprv."

 ==Backwards Compatibility==
 
 This BIP is not backwards compatible by design as described under [#considerations]. An incompatible wallet will not discover accounts at all and the user will notice that something is wrong.
