You generally shouldn’t store per-user data in a shared object on Sui because every change to a shared object requires consensus, which slows down performance and creates unnecessary contention when many users interact at once; instead, giving each user their own owned object avoids consensus overhead, lets their transactions run in parallel, and scales much better as activity grows.
