Does BU has such logic?
The logic behind EC, as implemented by BU, ensures that no amount of confirmations is enough to secure your payment due to chain reorganizations (not that this is relevant to the 100 number).Will be nice to see BU fork away forever.
Ironically, those who claim to be "pro-users" and "pro-capacity" are the ones that are staling a capacity increase. Without BU, we'd be long within >1 MB blocks due to Segwit activation & usage.This majority hash power supporting them may do rogue things to core chain and the only option left at that time will be to change the algo.
They can surely attempt that. Good luck explaining this behavior to anyone looking to join their chain (investment, development and any other kind of form of interaction). "Remember that time when we played dictators and attacked anyone who didn't obey our rules?"
