I don't know what you mean by "render the replay threat moot." If you don't have replay protection, replay is always a threat. A very serious one. -- Please do not email me anything that you are not comfortable also sharing with the NSA. > On Jun 6, 2017, at 5:19 PM, Kekcoin > wrote: > > Hmm, that's not the difference I was talking about. I was referring to the fact that using "post-chainsplit coinbases from the non-148 chain" to unilaterally (ie. can be done without action on the 148-chain) taint coins is more secure in extreme-adverserial cases such as secret-mining reorg attacks (as unfeasibly expensive they may be); the only large-scale (>100 block) reorganization the non-148 chain faces should be a resolution of the chainsplit and therefore render the replay threat moot. >
