Even if to someone who didn't care about anyone's privacy at all, non-taproot is simply inefficient. In the (I argue) overwhelmingly common case of everyone-agrees simple hash based branching requires a 30% overhead to communicate the commitment to the untaken branch (and worse in the case of extensive aggregation). I don't think an argument can be sustained in favor of that kind of communications overhead. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
