If there +is consensus among major exchanges and merchants, the preference of +miners are not particularly relevant. A checkpoint could be +implemented in a decentralized way to make sure miners of the original +chain won't be able to overtake the new chain. + +Bitcoin has no intrinsic value. Bitcoin has value because people are +willing to exchange it with something really valuable (e.g. a pizza; +or USD which could buy a pizza). If most bitcoin-accepting business +agree to follow BIP102 and ONLY BIP102, then BIP102 is THE Bitcoin, +and the original chain is just a dSHA256 alt-coin which one can't even +merge mine with BIP102. Switching to BIP102 is the only economically +viable choice for miners. + +Having said that, a miner voting may still be useful. It is just to +make sure enough miners are ready for the change, instead of measuring +their consensus. For example, the new rule will be implemented 1) 1 +week after 70% of miners are ready; or 2) on 1 Feb 2016, whichever +happens first. + +For SPV wallets, they have to strengthen their security model after +the BIP66 fork, anyway. They should be able to identify potential +consensus fork in the network and stop accepting incoming txs when it +is in doubt. My "version 0 flag block" proposal could be a good +generic way to indicate a hardfork to SPV wallets. (see my previous +email on this topic) + + |
