19:21:36 Lucas[m]1: were you one of the people interested in tx chaining? what kind of ‘timing’ do usecases for chaining have? I mean the delta between tx construction and submission. If the delta is low enough (eg less than a ~day) in the majority of usecases, then it may be feasible to A) support, B) convince people it is worth supporting. 19:27:44 If the delta is too big then it is impossible to avoid fingerprinting txs based on the gap between ‘newest’ ring member and ‘next newest’. Introducing new ways to fingerprint tx is not very enticing.
