Alice's payment in step 2 pays to a non-standard script. This is an improvement over the cut and choose, but it will only work for coins which allow non-standard scripts (type 2 in the BIP). I guess I was to focused on maintaining standard scripts on the altcoin. --001a113ff3264c9944052b8fcd64 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable
