The Frontier

Vlad argues that the 2017 split was more political than technical because SegWit already increased Bitcoin's effective block capacity. Bitcoin Cash's initial 8-megabyte blocks offered only a minor throughput advantage over Bitcoin's upgraded capacity.

Unlike upgrades like SegWit or Taproot, which establish rules for unclaimed script space, BIP 110 is an invasive soft fork designed to restrict active user behavior. This fundamental difference alters the social dynamics of user-activated soft fork enforcement.

Peter Wuille suggested using variable commitment styles to integrate post-quantum witness data. This approach avoids introducing a third transaction identifier, allowing unupgraded nodes to process transaction traffic using standard SegWit witness commitments.
