Is the assumption of a group of >miners suddenly switching (for example, they realise that they didn't >intend to support the new rules)? Or they're economically rational miners, and a large difficulty decrease on the original chain, without an equally large decrease in the value of original chain tokens, has made it profitable to switch? It's dangerous to assume all miners will continue to support the side they have initially signaled. They're only invested in the chain they mine for a short time (until coinbase maturity.) If both sides if a fork retain value you'd expect mining to redistribute itself WRT short term profitability at every difficulty adjustment, irrespective of initially signaled support for the fork. -----BEGIN PGP SIGNATURE----- Version: APG v1.1.1 iQFABAEBCgAqBQJVsZIuIxxHYXJldGggV2lsbGlhbXMgPGdhY3J1eEBnbWFpbC5j b20+AAoJEEY5w2E3jkVEN7YIAIlgaAahHCssIEXYzqB1gRKYRP4fPsq8NtOMrkki dc1gfKmprlPDShFvu2Hn5L8amP51ouRpmDSJwNyU//1DyU5p1tcWTAtkHr6SY7TY uJtcPMM03BUD2i3rXSY4FbpWn8aOoUnQrkYFhx5Y/Aru+l47C0I5KF4fgMag7FhI RxkTFylvq7uWvu0QCUkVh1MgohNxMqIGAvE5t8yoj5LxrNzOq95TcOGwFngWCdJM a5BADFjq7v4j/+cP748ZTPcLUusTQTwEuIsCIhpwwiKADsy1FKjmAdHhKTff/6wn cpNYvwimKNSSESCwzAnxekaJCTXpEOWQV7/6FO9vJbTMKw8= =/hJk -----END PGP SIGNATURE-----
