Moreover, while we at least have a soft fork mechanism that is not trivially exploitable (yes, it's got issues...but unlike SPV wallets, it isn't so easily exploitable), we have NO hard fork mechanism in place that isn't highly prone to systemic consensus failure.\n\nBut I think pretty much anyone who hasn't been in a coma for the last several years knows this...and I'll stop repeating the obvious.\n\nOn September 28, 2015 5:26:17 AM PDT, Mike Hearn \u003chearn at vinumeris.com\u003e wrote:\n\u003e\u003e\n\u003e\u003e Go ahead and object to soft forks...but at least try not to make\n\u003earguments\n\u003e\u003e based on changing the definitions of terms we all generally agree\n\u003eupon.\n\u003e\u003e\n\u003e\n\u003eI don't intend to do that, and I don't think I am - I know what the\n\u003edifference between a soft and hard fork is and am not trying to confuse\n\u003eor\n\u003eblur the two.\n\u003e\n\u003eTo reiterate: this current BIP implements a soft fork.
