There are several reasons why I decided not to use BIP39 in Electrum. One of them was that BIP39 seed phrases do not include a version number. A version number is needed in order to maintain backward compatibility, everytime you change the address derivation. Electrum will allocate a new version number for seed phrases that should be derived to segwit addresses. I guess BIP39 designers will have to change the semantics of their checksum bits, in order to encode a version number for segwit. --Ue7LvMs5BAt6NSUdlmeNsPP65QAmw4PGB-- --daEsUSF9tV0B5x5jTirWEQbPptlVNlKgR Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBCgAGBQJXODkJAAoJECvVgkt/lHDmM7UP/0Or/uGU6RI+v9FP0dDiIC42 pqvxf7G+gUAMG6+tVvD39GPUYbqW5YtIN0N4dwl+ltdFp8iF6x/N3K/kx8fEaJaH 6FLXyQoAVI28t8Q5hmcfM6ZikkwuDy7dEWspykgArOnsp3hWwbQejs9Rn2kVfSiW 44zZXOIKvUaebHKiHcWWHJ1pSGqwKARddPVMf/VwsGv/DbM/jYGTb5nfW/x+savr XzuKP3A4YgGtQUft03vk5YcAUPdNg6PFxWPjUvnzRLWr9JqZKKmGSwgQsY/pcuy2 FvehtY+sa7FwVRYIztWOF8kvJ99YM+qfsSMMTUlOnrCsdvMTNrasxLOi7KjMt/Sx iNNtuTUqfcxCt/WcbPyvFKNGkQydGW3oucIshXi9m8tqSy5czH8ymebL3KG+PwNj eSu3pG2NAIcwv9hoSf2Bv96hQ7ylqMYeT+oiARx7hLReNbBK8dRxeJRmZ3SnvW86 PVw++isHXSlPPLgSkxfSfRZU+4ojwZinzEXeuppUbcPlaBNIjbOywPeNs+eGP1QB h4u7+lC6c2SXWD4MlztzOb0fZuA+HQL2RjwvNldIHb0jcEKqXsyqDcYf1jsm50Z2 4q82aL2wXEbEprcgFkCy3/vF/KxTAc9eHkMFIGg713g/u/TsnlTFH8c8hgzzVMNm kcIZRuxWKI5msXnpPwIk =Yb+1 -----END PGP SIGNATURE----- --daEsUSF9tV0B5x5jTirWEQbPptlVNlKgR--
