Given the protocol requirements of the segwit proposal this is not the case. A miner running pre-segwit code will produce blocks that no segwit node will ever receive. It matters not whether these blocks contain transactions that are invalidated by the soft fork. Despite being valid to other pre-segwit nodes they will never be built upon by the majority hash power once segwit activates. At the same time, Peter's comment above is also incorrect. A "minority branch" *is* a set of blocks that have been orphaned (the term orphan being a misnomer, since these blocks of course have an ancestry all the way to the genesis block). That's precisely what is implied by the word "minority". So his description contradicts itself. e -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAEBCAAGBQJY2C6pAAoJEDzYwH8LXOFOf4gH/2e/euZ9bQxPKZyC7DN8us6T R1R9f+JFFsU3Vo8HkcU028Ib4aF0IAELvAWrhpZfH6ixZV2c3CJoi53rMbPmJ/+H Rlj0Qjc58mYpqosxyNoi0qPFZ2e3yCv+R5v9PQEeOdcGwXIr77Tij8lI1yu4uqHU bqJ3BXJLFpvL5iXOLhbakeu2qVIHqJnb1/hQMNh6eNM794n+UT2T8You52xUkuTm zJ+5CTQUiMNFE/HBWsbk8Vf3BTrM0sqMRTJzdr4VT1l+uOZn58BJJPFzLr2WeZww klAB/wK5oExMNlKQVy6Rw9+uFx88qRTl5s7LwFASOxEZYJIjd36bBaoTdqfaB5U= =pvlp -----END PGP SIGNATURE----- _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
