00:36:08 <m-relay> <c​haser:monero.social> I noticed that most of the current {1|2}-in/many-out tx's have only one transaction public key in tx_extra (33 bytes). IIUC this means all of their non-change outputs go to either 1. one or more primary addresses, 2. one subaddress, 3. one subaddress and one change address (thanks to tobtoht for explaining this). Monerujo's PocketChange strictly spends to distinct subaddresses. un<clipped message>
00:36:09 <m-relay> <c​haser:monero.social> less there's a wide adoption of a new, inferior anti-N-block lock mechanism or this is the dawn of hypermonerization (in the partial case of 1.), the rational explanation to me seems to be that these are black marble transactions that save money by having the smallest possible tx_extra.
